Presentazione1
Protists are a diverse group of eukaryotic microorganisms that do not fit into other kingdoms like plants, animals, fungi, or monera. Traditional classifications divided protists into animal-like protozoa, plant-like protophyta, and fungus-like slime molds and water molds based on superficial similarities. Modern classifications attempt to create monophyletic groups based on ultrastructure, biochemistry, and genetics. Protists exhibit different types of feeding, reproduction both sexually and asexually or through complex life cycles, and some are important pathogens or can be used to fight diseases and reduce insect populations.
Microbes
Microbes are tiny living organisms that cannot be seen without a microscope. They include bacteria, protists, fungi, tiny animals, viruses, and prions. Major groups of microbes are prokaryotes like bacteria, eukaryotes such as protists, fungi, plants and tiny animals, as well as viruses and prions. Prokaryotes have no nucleus and include eubacteria and archaea found in extreme environments. Eukaryotes range from protists to fungi, plants and tiny animals. Viruses contain genetic code but are not alive, and prions replicate using host proteins.
Plant Defence Mechanisms.pptx
Plants have evolved several defense mechanisms to resist exploitation by pathogens. These include constitutive defenses that are always present and induced defenses that are activated after exposure to a pathogen. A successful plant disease requires an interaction between the host plant, pathogen, and the plant's resistance. Plants defend themselves through basal resistance, which involves both constitutive and induced defenses that act as barriers to infection and disease development.

R.H. Whittaker proposed a five kingdom classification system that divides organisms into five kingdoms - Monera, Protista, Fungi, Plantae, and Animalia - based on their cell structure, whether they are unicellular or multicellular, their mode of nutrition, and their ecological lifestyle. The classification system places organisms on a continuum from prokaryotes to eukaryotes and from unicellular to multicellular. Many biologists accept Whittaker's classification of microorganisms which divides organisms into these five kingdoms.

This document summarizes key sections from a chapter about protists. It describes the characteristics of protists, including that they are a diverse group of eukaryotic organisms found in moist environments. It also outlines different types of protists like amoebas, algae, diatoms, and flagellates. Additionally, it discusses how some protists can affect human health, providing examples like malaria which is transmitted through a mosquito vector, and treatments for diseases caused by protists.
Chapter 21 and 22 notes
Protists and fungi are eukaryotic organisms. Protists can be unicellular or multicellular, autotrophic or heterotrophic, and include protozoa, algae, and slime molds. Some protists cause diseases like malaria and African sleeping sickness. Fungi break down organic matter as decomposers and form mutualistic relationships with plants through mycorrhizae and lichens. Both protists and fungi fill important ecological roles.
Food chain
Plants and algae are producers that make their own food through photosynthesis. Primary consumers are herbivores that eat producers, secondary consumers are carnivores and omnivores that eat primary consumers, and tertiary consumers are carnivores and omnivores that eat secondary consumers. Decomposers like fungi and bacteria feed on the remains of dead living things.

Protista Kingdom
Protists are eukaryotic organisms that are mostly single-celled and can reproduce both sexually and asexually. They are decomposers and consumers. There are three main groups of protists: fungus-like protists, plant-like protists called algae, and animal-like protists called protozoa. Protozoa move using flagella, cilia, pseudopods, or they cannot move if they are parasitic. Some disease-causing protists are Giardia, which causes diarrhea, and Plasmodium, which is carried by mosquitoes and causes malaria.
Innovative activities in the classroom
http://eduwebinar.com.au - I was inspired by a post by MrHooker about 21 things teachers should do, so put together this presentation which explores 18 of these innovative activities that you can do in your classroom.
Plant kingdom
This document provides information about different kingdoms of plants. It begins by listing the main kingdoms - Bryophytes, Pteridophytes, Gymnosperms, Angiosperms, and Algae. It then focuses on describing Algae in more detail, including their characteristics, reproduction methods, economic importance, and classification into three main classes: Chlorophyceae, Phaeophyceae, and Rhodophyceae. Brief descriptions are also provided for Bryophytes, Pteridophytes, and Gymnosperms.
Atmosphere Powerpoint
The document discusses the four main systems that make up Earth: the atmosphere, hydrosphere, biosphere, and geosphere. It focuses on describing the layers of the atmosphere, including the exosphere, thermosphere, mesosphere, stratosphere, and troposphere. The troposphere contains most of the weather and clouds and temperatures decrease with increased altitude. The stratosphere contains ozone that absorbs UV radiation. The mesosphere is the coldest part while the thermosphere reaches temperatures over 1,700°C and protects the Earth from radiation.
Layers of the atmosphere
The document summarizes the four main layers of Earth's atmosphere:
1) The troposphere, the lowest layer where weather occurs and temperatures decrease with altitude. Most water vapor and clouds are found here.
2) The stratosphere, which contains the ozone layer that absorbs ultraviolet light. Temperature increases with altitude in this layer.
3) The mesosphere, where meteorites burn up before reaching Earth's surface. Temperatures decrease with altitude in this layer.
4) The thermosphere, the uppermost layer where the temperatures sharply increase with altitude and the aurora occurs. Some satellites orbit within the thermosphere.
Water Cycle[1] Power Point
The water cycle describes the continuous movement of water on, above, and below the surface of the Earth. The sun warms water in oceans and lakes, causing it to evaporate into water vapor in the air. Water vapor condenses to form clouds, and air currents move clouds around the world. When clouds become too full, water falls as precipitation like rain or snow. Precipitation returns to oceans, lakes, and rivers, where the cycle repeats.
Action Research
Ms. Wong, a third grade teacher, wants to address a disruptive student's behavior through action research. She plans to use a single-subject A-B-A-B design to study the effects of time-out on the student's disruptions. First, she will establish a baseline by observing the student's behavior for several days. Then she will introduce time-out periods for a few days to see if it decreases disruptions. She will repeat the cycle, ideally finding that time-out reduces the problematic behavior so it is no longer needed. The main challenge will be observing the student during time-out while still teaching other students.
Action research related to Classroom problems
This document provides an overview of action research related to classroom problems. It discusses that action research is a method for teachers to study problems in their classrooms to improve student outcomes. The key aspects covered include defining action research, its purpose in education, who it is for, the practical focus on immediate classroom problems, and the collaborative nature. It also outlines the typical process of conducting action research, including identifying problems, developing hypotheses, implementing interventions, analyzing data, and sharing results. Examples of potential areas of focus for classroom action research are also given.
Biology 26.1
This document defines key terms related to the animal kingdom, including invertebrates, vertebrates, feedback inhibition, blastula, protostomes, deuterostomes, radial symmetry, bilateral symmetry, and more. It describes animals as multicellular, eukaryotic heterotrophs and outlines their essential functions of feeding, respiration, circulation, excretion, response, movement, and reproduction. Complex animals are noted to have high cell specialization, internal organization, bilateral symmetry, a head with sense organs, and a body cavity.
Biology 26.2
Sponges contain specialized cells like choanocytes that use flagella to move water through the sponge for feeding, respiration, circulation, and excretion. They have structures like spicules made of calcium carbonate or silica that form their skeleton, and archaeocytes that produce these spicules. Sponges reproduce through internal fertilization and larval stages, and some can form protective gemmules during unfavorable conditions.
Biology 22.5
Angiosperms are flowering plants that reproduce sexually through flowers. Flowers contain ovaries that surround and protect seeds. Angiosperms are divided into monocots and dicots based on whether their seeds have one cotyledon (monocot) or two cotyledons (dicot). Flowering plants can also be annuals, biennials, or perennials depending on whether their life cycle is one, two, or more than two years.
Earth science 13.1
The document discusses Precambrian time from 4.56 billion years ago until the Cambrian period over 4 billion years later. It describes shields as flat expanses of ancient metamorphic rock within continental interiors. Stromatolites are layered mounds formed from algae trapping sediment and calcium carbonate. Earth's original atmosphere lacked oxygen but primitive organisms evolved photosynthesis which began releasing oxygen into the atmosphere around 2.5 billion years ago.
Earth science 13.4
The Cenozoic Era saw the rise of mammals as the dominant land animal, replacing reptiles. Flowering plants known as angiosperms also became the dominant land plant over gymnosperms. Major geological events like mountain building, volcanism, and earthquakes occurred in western regions due to plate tectonics during this era. Mammals were better adapted than reptiles for more active lifestyles through bearing live young and maintaining steady body temperatures.
Earth science 13.2
The Paleozoic Era saw an explosion of life, as the continents of Gondwana and Laurasia formed most of the southern and northern portions of the supercontinent Pangea. During the Cambrian, Ordovician, and Silurian periods, life was restricted to the seas surrounding Gondwana, which contained the continents of present-day South America, Africa, Australia, Antarctica, and parts of Asia. By the end of the Paleozoic Era, around 400 million years ago, all continents had fused into the single landmass of Pangea, and plants first began moving from waterside habitats onto land.
Earth science 13.3
The Mesozoic era was the Age of Reptiles, where reptiles like dinosaurs quickly became the dominant land animals due to developing shelled eggs. Gymnosperms also dominated as the prominent plant during this time. A major geological event was the breakup of the supercontinent Pangea. Many reptile groups went extinct at the end of the Mesozoic era.
Earth science 9.1
Continental drift is the hypothesis that the continents were once joined together and have since drifted apart. Originally proposed by Wegener, it suggests the continents were part of a supercontinent called Pangaea approximately 200 million years ago that has since broken apart, moving the landmasses into their current positions. Fossil and rock evidence support this idea, including matching fossil organisms and mountain ranges found on separate continents today that indicate the continents were once joined.
Earth science 8.2
This document discusses seismograms and the different types of seismic waves that are recorded, including P waves, S waves, and surface waves. It explains that seismograms amplify and electronically record ground motion from earthquakes, allowing scientists to determine the epicenter location using travel time graphs from multiple seismographs. The document also covers historical intensity and magnitude scales used to describe earthquake size and introduces moment magnitude as the most widely used scale today because it estimates the energy released.
Biology 28 2 groups of arthropods
This document defines and describes key anatomical terms used to classify groups of arthropods. It discusses the cephalothorax, thorax, and abdomen found in crustaceans, as well as specific structures like the carapace, mandibles, chelipeds, swimmerets, chelicerae, pedipalps, and spinnerets. It concludes with three key concepts: arthropods are classified by body segments and appendages, especially mouthparts; crustaceans typically have two antennae, two or three body sections, and mandibles; and chelicerates have chelicerae mouthparts and two body sections, with nearly all having four pairs of walking legs.
Biology 2.4
Chemical reactions involve reactants being converted into products through breaking and forming chemical bonds, requiring a minimum amount of energy called the activation energy. Catalysts like enzymes speed up reactions by lowering this activation energy, with enzymes being protein catalysts that facilitate substrate reactions within cells.
Earth science 12.3
This document discusses radiometric dating and how it is used to determine the absolute ages of rocks and minerals. It explains key concepts such as radioactivity, half-life, and how comparing ratios of radioactive isotopes like carbon-14 and carbon-12 can be used to calculate radiocarbon dates for samples. Radiometric dating relies on the fact that radioactive isotopes decay at a constant rate and comparing the amounts of parent and daughter isotopes allows the age of a sample to be estimated.

Wind shapes landscapes through processes like deflation, desert pavement formation, and loess and dune deposition. Deflation is the lifting and removal of loose material by wind. Desert pavement is a layer of coarse pebbles created when wind removes finer material. Loess deposits are windblown silt deposits that form blanket-like layers, while dunes are ridges of wind-deposited sand that can vary in shape depending on wind and vegetation factors.
Earth science 7.2
Much of the weathered debris in deserts comes from mechanical weathering like alluvial fans formed where stream slopes abruptly decrease. While chemical weathering is less common, over long periods clays and thin soils can form. Desert streams are ephemeral, only flowing after rain, and often drying up before reaching oceans due to evaporation and soil infiltration. Most desert erosion comes from running water, though wind also erodes deserts, water does the most erosional work.
Earth science 7.1
Glaciers are large masses of ice that originate on land from compacted snow and move due to gravity. During an ice age, large ice sheets form on continents and flow outward, carving U-shaped valleys and depositing unsorted sediment called till. Valley glaciers are smaller glaciers confined to mountain valleys that flow due to plastic deformation and basal sliding between the ice and bedrock.
Earth science 6.3
Groundwater exists below the surface in the saturated zone where all spaces between rock and sediment are filled with water. The water table marks the top of this zone, and groundwater moves slowly through porous and permeable materials. Springs form where the water table intersects the surface, and overuse or contamination can threaten groundwater supplies in some areas. Karst regions have irregular terrain with sinkholes caused by erosion of soluble rock by groundwater in caverns below the water table.
Earth science 6.2
This document defines key terms related to streams and their processes, including bed load, capacity, alluvium, delta, natural levee, floodplain, flood, drainage basin, divide. It also describes concepts such as how streams erode and deposit sediment according to flow velocities, and how flooding occurs and can be mitigated. The overall work of streams is to shape the landscape through erosion, transportation, and deposition of sediment within drainage basins.
Earth science 6.1
The document discusses key concepts about running water and the water cycle. It defines terms like infiltration, transpiration, gradient, stream channel, discharge, tributary, base level, and meander. It explains that water constantly circulates among the oceans, atmosphere, geosphere, and biosphere in the water cycle. Balance in the cycle means annual precipitation equals evaporation globally. A stream's ability to erode and transport materials depends on its velocity, while gradient decreases and discharge increases from headwaters to the mouth.
