The beaver lives near wooded streams and builds large dams and lodges out of branches and mud. It is considered an engineer for how it strategically cuts branches and uses the river currents to transport materials. The beaver builds dome-shaped lodges with multiple chambers, including areas above and below water level, and stores food underneath for winter. It dams rivers and streams to form deep ponds to protect against predators and ensure access to food and shelter during freezing temperatures. Beavers mate for life and have litters of 3-4 young in the spring and summer.

Sparrows
House sparrows are small, brightly colored birds that have adapted to living alongside humans. However, their populations are declining worldwide due to changes in architecture and agriculture that remove nesting sites and food sources. World Sparrow Day is celebrated annually to raise awareness about threats to sparrows and ways to increase their populations, such as providing bird feeders, conserving habitats, and educating others.

It describes different terrestrial habitats including jungles, forests, deserts, and savannas. It provides examples of animals that live in each habitat and characteristics of those habitats. It also discusses different aquatic habitats including oceans, fresh water, and polar regions. It provides information on animal adaptations for different habitats and activities to help students learn about habitats.
Polar bear ppt
Polar bears are the largest land carnivores. They can grow up to 10 feet long and weigh over 1,700 pounds. Polar bears have thick fur to keep them warm and hollow hairs that act like straws to keep them dry. They live in Arctic regions and hunt seals, which they eat to sustain their large bodies. Polar bears communicate through growls, roars, and body language to warn, play, or scold each other.
Animal power point (gray wolf)
The gray wolf, scientifically known as Canis Lupus, is a species found across the Northern Hemisphere. Gray wolves have a varied diet consisting of large prey like elk, moose, and deer. They live in packs that typically include 2-12 wolves, with a breeding pair that gives birth to litters of 4-6 pups. While not currently at risk of extinction, some local wolf populations remain threatened.
Glaciers
- Glaciers are large persistent bodies of ice that form where snow accumulation exceeds melting over many years. Their sheer weight and plasticity causes them to slowly flow under gravity.
- The approximate areas covered by glaciers worldwide are provided, totaling nearly 15 million square kilometers, with over half of that in Antarctica and Greenland.
- Glaciers are classified by their location and behavior, such as ice sheets, ice caps, valley glaciers, and tidewater glaciers.
Grassland
The grasslands biome is dominated by grasses and other herbaceous plants called forbs. It covers more of the Earth's surface than any other biome. North American grasslands can be divided into tallgrass, mixed grass, and shortgrass prairies depending on the average precipitation and height of the dominant grasses. While grasses remain green and growing in the spring and summer, they become brown and dried out in the autumn and winter. Grasslands support a diversity of primary consumers and provide habitat for species like bison, prairie dogs, meadowlarks and rattlesnakes. However, over 99% of North American grasslands have been converted to agricultural use like growing corn and wheat.
Endangered species
Scientists determine if a species is endangered based on estimates of its breeding rates, threats from predators or disease, and population decreases over time. The Endangered Species Act of 1973 provides protection for species classified as endangered or threatened throughout a significant part of their range in the United States. Examples of endangered species include the sun bear, honey bee, quokka, kakapo, saola, and sand cat.
Grassland Biome

Chapter 19.1: Land Biomes
Grade 8 Integrated Science Chapter 19 Lesson 1 on land biomes. This lesson covers basic characteristics of the 7 major land biomes: deserts, grasslands, temperate deciduous forest, temperate rainforest, tropical rainforest, taiga, and tundra. The objective is that students should be able to recall defining characteristics of each biome and identify a biome by temperature and precipitation.
Habitats for kids!
The document defines several major habitat types on Earth: oceans cover 71% of the planet's surface; coastal areas have shallow waters near land; rainforests have tall trees, warm climates, and abundant plants and animals; polar regions are the coldest areas in the north and south; deserts are extremely dry with little water and few plants or animals; and grasslands have grass but few trees due to dry or poor soil conditions.
Grade 2 going outside (freshwater habitat) ppt 2
Habitats provide shelter for animals and can be found in water or on land. Water habitats include rivers, ponds, streams, and lakes and are home to animals like dragonflies, mosquitoes, and water snails as well as freshwater plants. Land habitats provide shelter on dry ground for other species.
Fox
fox is the smallest canid found in the world having short legs,bushy tail,small narroe pointed muzzle.primarily it is an omnivorus animal,lives in den.
Bears
Storybook bears are bears that live in storybooks. They live in houses, sometimes people houses and sometimes in trees, and all over the world. They eat foods like porridge, honey, and people food. Storybook bears come in different sizes, colors, and may or may not wear clothes. Some look like real bears while others look like teddy bears.
Real bears have characteristics like broad shoulders, short backs, and short thick legs. They are found all over the world and eat things like fruits, plants, small animals, and insects depending on the specific type of bear. The document then provides information on characteristics and habitats of different types of real bears like spectacled bears, sun bears, giant pandas
Plant Adaptations
Plants have developed various adaptations to survive in different environments. The document discusses plant adaptations for obtaining water, sunlight, and protection based on their habitat. Desert plants like cacti store water in their stems and have waxy coatings to reduce water loss. Grassland plants have deep roots to absorb water and narrow leaves to minimize transpiration. Forest trees vary based on climate - tropical trees have buttresses and drip tips, deciduous trees drop leaves, and coniferous trees retain needles year-round. Tundra plants are low-growing and have shallow roots to survive the harsh conditions. Overall, plant adaptations allow them to obtain resources and protect themselves in their particular environments.
Snakes
Snakes are found worldwide except Antarctica and come in many shapes, sizes and colors. There are about 3,000 snake species, around 375 of which are venomous. Snakes have excellent senses of smell and vision which help them hunt prey. They swallow prey whole due to flexible jaws and teeth pointed backwards. Snakes shed their skin as they grow and most mate annually. The largest snake is the reticulated python and smallest is the thread snake. While some snakes are dangerous, most are beneficial and their habitats are disappearing.
Walruses
Walruses are marine mammals that live in the Arctic and Pacific oceans. They travel by swimming or walking on land using their flippers. Walruses eat clams and soft-bodied animals like worms, gastropods, and crustaceans. They use their large tusks to catch food or defend themselves against threats. Walruses must adapt to harsh Arctic winters by migrating, getting into piles to stay warm, or using their tusks to break ice if trapped underneath.
ALL ABOUT PLANTS
The document discusses different types of plants and their parts and functions. It describes trees, shrubs, herbs, climbers, creepers and other small plants. It explains the roles of roots, stems, leaves, flowers, fruits and seeds. It discusses how plants make their own food through photosynthesis and provides food and shelter for animals.
Animal´s habitats
Animals live in habitats that provide food, shelter, and space to raise young. A habitat can be an ocean, river, forest, pond or other natural environment where plants and animals find the resources they need to survive. Many different animal species can share the same habitat, with habitats like forests being home to foxes, bears, owls and squirrels.
Plants
This document discusses different types of plants and their characteristics. It describes trees as tall plants with trunks, branches, leaves and roots. Evergreens keep their leaves all year while deciduous trees lose their leaves in autumn and winter. Bushes are short with many stems and leaves but no trunk. Grass is green and bendy. Some plants like trees and bushes are cultivated while others like grass grow wild. Flowers grow fruit to protect seeds inside while non-flowering plants like ferns and moss use spores to reproduce. The document provides a vocabulary list of plant-related terms.
Animals in Danger
Many animal species are endangered or face extinction due to natural causes like disease, competition, and natural disasters, as well as man-made threats including poaching, habitat loss, and commercial exploitation. Specific animals mentioned that are endangered include the Iberian lynx due to habitat loss and poaching, polar bears whose sea ice habitat is diminishing, tigers whose bones and body parts are used in traditional medicine and habitat is destroyed, gorillas whose forest habitat is invaded and destroyed from human activities, and pumas which depend on intact habitats for survival.
Animal intelligence
Dolphins are marine mammals closely related to whales that vary in size but generally weigh around 40 kg. They have streamlined bodies and are carnivorous, mostly eating fish and squid. Dolphins have acute eyesight, can hear much higher frequencies than humans, use their teeth like antennae, and have a well-developed sense of touch. They communicate through whistle-like sounds, occasionally leap out of the water, and can sleep with half of their brain at a time.
Soil for 3rd or 4th graders. (Teach)
1) Soil is formed from two main components - tiny pieces of weathered rock and humus, which is composed of decomposed dead plants and animals.
2) Rocks are weathered into smaller pieces through natural forces like water, wind, freezing and thawing. Over long periods of time, these break rocks down from boulders into soil.
3) Humus is formed as bacteria, fungi and invertebrates decompose dead organic matter through a process of rotting and decay. This decomposition of plants and animals is what creates the dark, nutrient-rich organic component of soil.
Rainforest animals and their adaptations
Animals in tropical rainforests have developed various adaptations for survival. Some animals are able to climb trees to forage for food, while others can swim or are nocturnal to avoid heat and competition. Many rainforest animals have camouflaging colors and patterns to hide from predators or warning colors to deter predators while still blending in. Some birds have evolved strong or long beaks suited to their environments.
Grasslands ecosystem
Grasslands are ecosystems dominated by grasses rather than trees. There are two main types: temperate grasslands like the North American prairies, and savannas near the equator. Temperate grasslands have colder winters and get less rain than savannas. Both ecosystems support many large grazing animals and are important for livestock agriculture, but they are threatened by conversion to cropland and urban development. Conservation efforts include protecting wildlife, controlled burning, and preventing overgrazing.
Forests deciduous evergreen
The document discusses deciduous and evergreen forests. It describes deciduous forests as shedding leaves seasonally, occurring in areas with 70-200 cm of annual rainfall, and providing habitat for animals like bears, squirrels, and deer. Evergreen forests are found near the equator in tropical regions receiving over 200 cm of rainfall each year. They form dense canopies and support biodiversity, including elephants, monkeys, and birds. The document also outlines four main types of forests - tropical and temperate evergreen, mediterranean, and coniferous - and notes their climates, vegetation, and examples of resident wildlife.
Sydney thomasen polar bears
Polar bears are the largest land carnivores, inhabiting Arctic sea ice, water, and coastal areas. Males can grow to over 2.5 meters and 650 kg, while females reach 1.8-2.5 meters and 150-500 kg when pregnant. Polar bears primarily feed on seals but will also eat beluga whales, narwhals, and bowhead whales. Their habitat and ability to hunt is threatened by pollution and climate change causing sea ice to melt. Conservation efforts include reducing greenhouse gas emissions and not purchasing fur products.
Beavers by Reagan
Beavers are brown or dark brown mammals that are around 3 feet long. They live near bodies of water in North America, where they build dams out of trees and branches to create shallow ponds. Beavers eat bark from trees and use their teeth to fell trees, building lodges in the process. Baby beavers are called kits and can grow from 1 pound at birth to 25 pounds within a year. While beaver dams sometimes flood areas, their ponds also help prevent forest fires.
Mattaya best
Beavers are large rodents native to Canada that grow up to 1 meter long and weigh 30 kg. They have two layers of fur and teeth that continually grow. Beavers build lodges out of mud and sticks near forests and streams, and spend their time chewing food and storing it in their lodges for winter. Their predators include wolves, bears, hawks and owls. Baby beavers, called kits or pups, can swim at birth and leave home at 2 years old. Beavers are known for their skills at swimming, cutting down trees, and building lodges and dams, making them a symbol of Canada featured on the Canadian nickel.

Albatrosses are amazing travelers that can fly long distances over oceans. They have hooked beaks to easily catch fish and can dive underwater. However, many albatrosses are dying after getting trapped in fishing nets, with over 100,000 dying each year. Albatrosses live for 50-60 years and their chicks stay on land for 9 months.
Penguins live in both cold and warm climates and come in various sizes, from the smallest little blue penguin to the largest emperor penguin. Penguins are excellent swimmers and divers, with emperor penguins able to dive over 500 meters deep and stay underwater for 20 minutes. Their feathers trap air to keep them warm since they cannot fly.
Why did eagle populations decline in the 1960s Why do eagles cong.pdf
Why did eagle populations decline in the 1960\"s? Why do eagles congregate at the Shepaug
River and Hudson Rivers in winter? When do they reproduce? What are their nests like? How
many young do they have and when do they hatch out? What types of behavior do adult eagles
engage in in winter? What percent of the time do they spend searching for food? What habitat
do they prefer for nesting sites? Why?
Solution
Answer:
1. Why did eagle populations decline in 1960s: Different reasons contributed to a steep decline in
Eagle population in 1960s:
- More than 100,000 bald eagles were killed in Alaska from 1917 to 1953 as Alaskan Salmon
fisherman feared that Eagles were a threat to the Salmon population
- In the 1950’s the insecticide DDT (dichlorodiphenyltrichloroethane) was introduced and used
widely to combat a broad spectrum of insect pests. DDT was indiscriminately used and it caused
serious environmental effects DDT interferes with the calcium processing of birds and results in
deformed eggshells. The chemical by products of DDT persisted in the aquatic ecosystem long
after its application. Since bald eagles are at the top of the aquatic food chain and feed primarily
on fish, they received concentrated doses of the chemical. When the female eagle laid a thin,
deformed eggshell, she crushed it under her own weight when incubating the egg. Since bald
eagles pairs breed only once per year, with many bald eagle pairs not reproducing successfully,
the bald eagle population declined steeply throughout the 1960’s and 1970’s.
2.Why do eagles congregrate at the Shepaug River and Hudson river in the winters.
The same elements that support breeding pairs - clean air and water, ample food supply, large
undisturbed stands of trees - also attract bald eagles looking for a winter home.
The Hudson River region still provides tracts of relatively undisturbed land for roosting,
perching and nesting.These habitats are especially attractive during winter, when human activity
is limited.
Each year, bald eagles migrate from their northern nesting areas to New York\'s rivers and
reservoirs in search of open water, food and roosting sites. Even during the coldest months, open
water can be found near power plants that discharge water during energy production, or where
the natural flows of tributaries enter the river. In recent winters, more than 100 wintering eagles
have been counted along the lower Hudson.In recent years, the stretch of the Hudson from
Kingston to Croton has been increasingly popular with bald eagles, probably because sections of
the river are kept open by discharges from power plants, and railroad tracks provide an ample
supply of dead animals (carrion) for scavenging eagles.
3. When do they reproduce? What are their nests like? How many young do they have and when
do they hatch out?
An eagle is sexually mature and ready to breed at about 4 to 5 years of age. For bald eagles, the
complete white head and tail are signs of sexual maturity. Golden eagles.

Multiple uses are possible as there are many cards included. Worksheets can be edited as needed.
Moose martina3
Moose have two layers of fur and skin hanging below their neck. They can weigh up to 600 kg and have black, brown, or white fur. Moose live in northern Canada and in forests near water. They eat plants like leaves and bark. Moose predators include wolves, bears, and humans. Baby moose are called calves, and calves can stand soon after birth and run after two weeks. Moose have adaptations like long legs, big hooves, and big noses and ears to survive in their habitat. Male moose grow antlers that can be over 2 meters wide and shed them in winter.

The document describes the creation of a mutated creature called the Great Bald Snakehead through combining DNA from a bald eagle, great grey owl, and snakehead fish. It was created through an insertion/deletion mutation over 10 years and can adapt to many environments, including living both on land and in water. The document also outlines three potential arenas - forest, water-based, and snow - that the Great Bald Snakehead creature could be placed in for survival purposes.
The Northern River Otter
The river otter has brown to black fur with a gray belly and chin. It lives in banks of rivers, small lakes, ponds, and dens made of mud and twigs. River otters mostly eat small fish, crayfish, frogs, small mammals, and aquatic insects. They give birth to litters of around 6 pups after a 2 month gestation period.
Arctic/Antarctic adaptions (Teach)
The Arctic tundra is a cold, treeless region around the North Pole where winter temperatures average -30°F. Summers are short and cool, allowing some plants like lichens, mosses, and low-growing flowers to survive. The ground is permanently frozen except for the top layer of soil. Antarctica is even colder, with temperatures below freezing year-round. Only lichens, mosses, algae and two flowering plants survive on its ice-free areas in summer. Penguins are the only birds that breed on Antarctica, finding food in the surrounding oceans. Both polar regions are home to animals like seals, whales, polar bears, and birds that have adaptations like blubber and thick
Water animals by freddie
Water animals include fish, turtles, octopuses, beavers, frogs, sea lions, crabs, and stingrays. Turtles hold their breath and swim with adapted shells, octopuses use camouflage and ink to defend against predators, and beavers build dams and lodges. Frogs lay eggs in water that hatch into tadpoles and become frogs, while sea lions are fin-footed and can live over 20 years. Crabs have thick shells and claws and live on land and in water, and stingrays are related to sharks and use tail barbs for defense.
Beavers
Beavers are known for building dams, canals, and lodges out of wood and other plant materials. They are semi-aquatic rodents that use powerful front teeth to cut wood to build these structures for shelter and transportation of materials. By constructing dams, beavers create deep ponds that provide protection and allow them to float building materials.
Problems with beavers
The document discusses problems caused by beavers and methods for removing them. Beavers are large rodents known for building dams that can flood forests, homes, and roads, damaging crops and trees. While some think destroying dams will make beavers leave, they can quickly rebuild the dam. Trapping is an effective control method, but requires expertise. The document provides contact information for a professional wildlife removal service.
Second periodtotal
The West Indian manatee lives in shallow coastal waters, rivers, and estuaries in warmer parts of the Americas. It has adaptations for staying underwater, like nostrils that can close tightly and a thick layer of insulating body fat. Its flexible upper lip helps guide vegetation into its mouth to eat.
Adaptations
- Many organisms have developed adaptations for coping with physical environmental factors like temperature, light, and water through structural or behavioral adaptations. Examples include thick fur in camels and polar bears and kidney functions in camels.
- Organisms also have adaptations for obtaining food like certain teeth structures for tearing or grinding, and beak structures in birds for different feeding behaviors.
- Adaptations also help with escaping predators through behaviors like hiding, living in groups, or having physical features like camouflage, warning colors, speed, or defenses. Cryptic coloration allows blending with backgrounds.
Riparian Zone
This document discusses the habitat needs of wild salmon in Whatcom County, including native riparian vegetation that provides shade and food, gravel for spawning eggs, habitat diversity with pools and riffles, and woody debris for shelter. It encourages readers to avoid disturbing salmon habitats by walking in rivers, removing logs or dead salmon, and provides contact information for a local organization working to restore salmon populations.
Muataion
The document describes several original creatures - the bald eagle, great grey owl, and snakehead fish - and their key characteristics. It then introduces a mutated creature called the Great Bald Snakehead, which is a fusion of DNA from the bald eagle, snakehead fish, and other animals. The mutation took over ten years to create and involves an insertion/deletion mutation that benefits the creature for hunting and self-defense. As a result of its mutations, the Great Bald Snakehead can adapt to many environments and survive both on land and in water.
Project
The document describes several original creatures - the bald eagle, great grey owl, and snakehead fish - and their key characteristics. It then introduces a mutated creature called the Great Bald Snakehead, which combines traits from the three original creatures: it can fly fast, breathe underwater, has sharp teeth for hunting, and enjoys eating human flesh. The document explains that creating this mutation took over ten years and involved an insertion/deletion mutation in its DNA that allowed it to adapt to many environments and survive with both gills and lungs.

The Fascinating World of Bats: Unveiling the Secrets of the Night
The Fascinating World of Bats: Unveiling the Secrets of the Night
Bats, the mysterious creatures of the night, have long been a source of fascination and fear for humans. With their eerie squeaks and fluttering wings, they have captured our imagination and sparked our curiosity. Yet, beyond the myths and legends, bats are fascinating creatures that play a vital role in our ecosystem.
There are over 1,300 species of bats, ranging from the tiny Kitti's hog-nosed bat to the majestic flying foxes. These winged mammals are found in almost every corner of the globe, from the scorching deserts to the lush rainforests. Their diversity is a testament to their adaptability and resilience.
Bats are insectivores, feeding on a vast array of insects, from mosquitoes to beetles. A single bat can consume up to 1,200 insects in an hour, making them a crucial part of our pest control system. By preying on insects that damage crops, bats save the agricultural industry billions of dollars each year.
But bats are not just useful; they are also fascinating creatures. Their ability to fly in complete darkness, using echolocation to navigate and hunt, is a remarkable feat of evolution. They are also social animals, living in colonies and communicating with each other through a complex system of calls and body language.
Despite their importance, bats face numerous threats, from habitat destruction to climate change. Many species are endangered, and conservation efforts are necessary to protect these magnificent creatures.
In conclusion, bats are more than just creatures of the night; they are a vital part of our ecosystem, playing a crucial role in maintaining the balance of nature. By learning more about these fascinating animals, we can appreciate their importance and work to protect them for generations to come. So, let us embrace the beauty and mystery of bats, and celebrate their unique place in our world.

Beaver
- 1. THE BEAVER
- 2. The beaver lives near wooded streams. Beavers are found in a lot of parts in Canada Where is the beaver live?
- 3. This creature is considered as A professional engineer and A hard worker at the same time that it makes its nest and establishes A dam to prevent water from destroying it It spends a super effort to finish its job in a several stages. it collects a huge amount of tree branches for its food and to build its home and dam. The Beaver's Nest For this purpose it gnaws the surrounding trees . scientific searches proved that it makes great calculations to choose which branches it needs and which would be suitable for its project and also it was proven that it prefer to work on the river's banks to make the water help him in collecting the branches which it already cut.
- 4. The beaver builds a home (lodge) made of mud and branches. The inside of the beaver's home is distinguished by a fabulous design with Tow underwater passages, a feeding area above the sea level and a dry area above it for the nest in addition to a fresh air hole at the top (roof) of the lodge. Beaver also make a food store under the nest to be fed from along the winter season and make another passages net-like in shape to lead him to the land and the trees which is its food most lodges are about 5 meters wide and 2 meters high
- 5. Mud is plastered on the outside of the lodge to make it strong Beaver gather branches with each other to form the outside structure carefully using small branches and mud in order not to leave any holes or gaps in it. This prevents enemies from breaking in. The mud also helps keep the inside warm during the winter although it's too cold in winters up to -35 C degree it keeps the temperature warm inside above zero C all the time
- 6. Beavers may also build dens or burrows along river banks. Sometimes they live in these bank burrows while they are building their lodge to hide from enemies. It also builds a dam which is made of branches, mud and rocks by gathering them above each other the same way like it builds its nest. This dam holds back the water and a deep pond is formed. The pond must be deep enough so water will not freeze to the bottom
- 7. The beaver is the largest rodent in North America. A full grown beaver can weigh from 16 to 32 kg. It can be from 60 to 80 cm. in length. Beavers have long sharp front teeth. A beaver's tail is flat (about 30 cm. long) and covered with scales. The beaver uses the tail to steer when swimming or for balance when sitting on land. If an enemy is near, the beaver slaps its tail on the water to warn other beavers. The tail is not used to plaster mud on dams or lodges. Appearance
- 8. The beaver's legs are short. It is not able to move quickly on land. But the beaver is a strong swimmer under water and on the surface of the water. The front feet have sharp claws. The beaver uses the claws for digging up mud and stones. The beaver uses its front feet for carrying mud and branches. With its back feet the beaver spreads waterproofing oil on its fur. The beaver's fur has to be oily to keep the animal waterproof.
- 9. Food Beavers eat the bark and leaves of trees. Their favorite tree is the aspen. Beavers also eat grasses, berries and water plants.
- 10. The beaver is well adapted for swimming. It can see well under water over its small eyes. The beaver's nostrils and ears can be closed when swimming. Adaptations The front teeth are very strong and sharp for gnawing and cutting down trees. Beavers pull smaller branches with their teeth. Bigger logs are rolled down to the pond with their front paws or their nose or the top of their heads.
- 11. Beavers mate for life. Early in the summer (May or June) the female has a litter of three or four kits. The newborn have fur, teeth and can see and walk. The babies remain inside for about a month. Beaver’s Family The yearlings act as babysitters for the new litter. During their second year, young beavers help their parents repair the dam and lodge and gather food for winter. Young beavers stay with their parents until they are two years old.
- 12. Wolves, coyotes, bears, and lynx are the enemies of the beaver. Beavers can be easily caught when they are on land. Enemies River otters have been known to slip into the lodge and kill the kits. In the winter when the water is frozen, predators can walk right up to the lodge. These animals may try to break into the lodge.
- 13. Thanks For Your Attention.
