BODY STRUCTURES THAT HELP ANIMALS ADAPT AND SURVIVE .pptx
Animals have body structures that help them adapt to their environment. ADAPTATION is
the structure or behavior that helps an organism survive in its environment.
HABITAT is an ecological or environmental area that is inhabited by a particular species of
animal, plant, or other type or organisms. Fish are covered with scales for protection from disease and
from other animals that live in water. Shrimps and lobsters are covered with outside skeleton or
exoskeleton while other animals like clams and mussels are covered with shells. Some animals are
covered with fur to keep them warm like monkey, lion, horse, and cheetah. Some animals that found in
the locality are carabao, cow, goat, dog and cat. Others are covered with feathers for flying like chicken,
eagle, peacock, and duck. Some have smooth skin for breathing like earthworm. Most body coverings
of animals are for protection.
Animals move differently depending on their habitat and their body structures. Some animals have
legs for walking and some have wings for flying. Animals that live on land move in different ways.
Some walk, hop and jump. Most animals that live in water swim. But some aquatic animals have legs,
too, for walking like crustaceans, shrimps, prawns, and crabs. Animals that can live both in water and
on land can either walk, hop, jump, or swim. Some animals used the following body structures to adapt
and survive: horns, tails, claws, paws, fangs, pincers, beaks, sticky tongue, movable jaws, sucking tubes,
and teeth.
These are the important information about the body structures that help animals adapt and survive
in their particular habitat.

It then discusses the factors that affect friction, the different types of friction (static, sliding, rolling, fluid), their definitions and examples. The document also covers the effects, advantages and disadvantages of friction, and methods to increase or reduce friction such as changing surface roughness or using lubricants. It concludes that friction is sometimes necessary but also causes issues, so it can be considered a "necessary evil".
Gravity
The document discusses the key concepts of gravity including:
1) Gravity is a force that acts between any two masses and depends on their masses and the distance between them, as described by Newton's law of universal gravitation.
2) On Earth, gravity causes all objects to accelerate downward at 9.8 m/s^2 when in free fall with no other forces acting on them.
3) Air resistance counteracts gravity and causes objects of different sizes and shapes to fall at different rates, though they would fall at the same rate in a vacuum. Objects reach a terminal velocity when air resistance equals the downward force of gravity.
Friction
Friction is the force that opposes the motion of objects in contact with one another. It causes objects to slow down and stop moving even without an apparent force being applied. Friction occurs due to bumps and hollows between surfaces and is greater on rougher surfaces, causing slower motion. While friction has disadvantages like causing wear and reducing efficiency, it also has advantages such as enabling brakes to stop moving vehicles and allowing objects to be gripped. Friction can be reduced by smoothing surfaces or adding lubricants between surfaces.
Ppt Friction
Friction opposes the motion of objects and is caused by bumps on surfaces sticking together when they touch. There are three main types of friction: static friction between non-moving surfaces, sliding friction between surfaces moving past each other, and rolling friction between rolling objects and surfaces. Adding sand to tires increases rolling friction and helps cars move on slippery surfaces by providing more traction between the tires and the ground. This relates to Newton's Second Law, as increasing friction generates a greater net force to overcome inertia according to the formula F=ma.
Energy, Heat & Light
The family was going to the beach on a sunny Saturday morning. Mother packed sandwiches and drinks in a basket. Father said it was time to go and the children were excited to leave. The sun provides light and heat energy. It can dry clothes and warm the air but too much sunlight causes sunburns and eye damage. Shade, hats, sunscreen and sunglasses can protect against too much sun.
Slideshare gravity, friction
Gravity pulls all objects toward the center of the Earth, causing things like pencils to fall when dropped. Friction is the force that resists the relative motion of objects in contact and can cause heat, as when rubbing hands together. Friction in car brakes and tires helps slow and stop vehicles safely. The document discusses gravity and friction, provides examples of each including falling objects and braking in cars, and asks questions to check understanding.
Earth magnetic field
The Earth has a magnetic field that extends into space and protects the planet. The magnetic field is generated by Earth's core and behaves like a giant bar magnet. It has a north and south magnetic pole that are located near the geographic poles but can wander over time. The magnetic field deflects solar winds and cosmic rays, protecting the atmosphere. It can be mapped and measured at different locations on Earth. Animals like birds are able to detect the magnetic field to aid navigation.
Heat, light and sound
Heat is a form of energy that makes things hot. The sun is a major source of heat for Earth, warming the land, air, and water. Other sources of heat include fires, lamps, stoves, and friction from rubbing hands together. Different materials warm up at different rates when exposed to heat - some parts of the street may get hot faster than others.
12 1 Friction And Gravity
Friction is a force that opposes the motion of objects that are touching and moving past each other. There are four main types of friction: static friction between non-moving objects, sliding friction between moving objects, rolling friction which is much less than static or sliding friction, and fluid friction caused by air or water resistance. Gravity is an attractive force that pulls objects towards the center of Earth. Falling objects experience both the force of gravity accelerating them downward and the resistance of air slowing them down, reaching a steady speed known as terminal velocity when these two forces balance.
Effects Of Heat Energy
The document discusses the effects of heat energy on solids, liquids, and gases. It explains that when materials are heated, their particles vibrate more and expand in size, taking up more space. When cooled, particles vibrate less and materials contract. Examples are given such as railway tracks leaving gaps for expansion, pipes being looped to prevent bursting, and balloons rising due to heated air expansion. A particulate model is used to explain that expansion and contraction occur due to changes in the spacing between particles rather than changes in particle size itself.
Section 2
This document discusses friction and gravity. It defines friction as the force that two surfaces exert on each other when rubbing together, and identifies four types of friction: static, sliding, rolling, and fluid friction. Gravity is defined as a force that pulls objects toward each other. The document explains how mass and distance affect gravitational attraction between objects. It also discusses concepts related to gravity and motion like free fall, air resistance, terminal velocity, and projectile motion.
Earth's magnetism
The document discusses the earth's magnetism and how it was studied over time. It explains that early civilizations noticed magnetic properties in rocks and how compasses were used for navigation. William Gilbert conducted experiments in 1600 which showed that the earth acts like a giant bar magnet. The dynamo theory later emerged to explain the earth's magnetic field as being generated by convection currents in the liquid outer core. Studies of ancient rocks have provided evidence that the polarity of the earth's magnetic field has reversed many times in the past.
Earth's magnetism
The document discusses the dynamo theory of the Earth's magnetism. It proposes that electric currents produced by the movement of liquid iron in the Earth's outer core generate the planet's magnetic field. Convection currents provide the energy needed to sustain the magnetic field over geological timescales. Paleomagnetic studies of fossil magnetism in rocks support the idea that the Earth's magnetic poles have reversed polarity multiple times in the past, consistent with the dynamo theory.
Earth’s Magnetic Field
The Earth's magnetic field is generated by electrical currents in the liquid outer core. The magnetic field traps charged particles from the solar wind in the Van Allen radiation belts. Rocks record the magnetic field at the time of formation, allowing scientists to study how the magnetic poles have reversed in the past. The magnetic field shields the Earth from solar wind and cosmic rays.
Friction
Friction is a force that opposes the relative motion between two objects in contact. There are two main types of friction: static friction and kinetic friction. Friction can be both helpful and harmful. It allows for walking and braking a bicycle but also causes wear and tear over time. Friction depends on factors like the roughness and weight of surfaces, and it can be increased or decreased through these surface properties.
Scientists behind Electricity and Magnetism
Hans Christian Ørsted discovered electromagnetism in 1820 when he observed that electric currents create magnetic fields, establishing the first connection between electricity and magnetism. Georg Ohm determined quantitatively in 1827 that the current through a conductor between two points is directly proportional to the voltage and inversely proportional to the resistance of the conductor, known as Ohm's Law. Michael Faraday discovered electromagnetic induction in 1831 when he found that a changing magnetic field can induce an electric current in a nearby conductor, the basis for electric generators and transformers.

Unit 6 heat, light and sound
This document provides information about heat, light, and sound. It discusses that heat is produced by the movement of atoms and molecules and is transferred from hotter to colder objects. Light allows us to see objects when it bounces off them and enters our eyes. Objects can be transparent, translucent, or opaque depending on how much light they allow to pass through. Sound is vibrations that propagate through a medium like air and are perceived through hearing.

Weight mass ws1
Matter is anything that has mass and volume. All matter experiences gravity and has mass. Gravity is the force of attraction between objects due to their masses. Weight is a measure of the force of gravity and depends on an object's mass and the strength of gravity where it is located. Mass is a measure of the amount of matter in an object and does not change with location, while weight can change depending on the gravitational pull of different locations.

Gravity
This document provides a worksheet on forces and equilibrium with 10 problems. It begins by explaining that mass is a measure of amount of matter while weight is the force caused by gravity, and one's mass would stay the same on the moon but weight would decrease due to lower gravity. It then provides problems involving calculating gravitational force based on given mass or finding mass based on given gravitational force. The remaining problems involve drawing force diagrams and using the concept of equilibrium to solve for unknown forces like tension or normal force.
G1
This document discusses the difference between mass and weight. Mass refers to the amount of matter in an object and is measured in kilograms. Weight refers to the gravitational force on an object and is measured in Newtons. Weight depends on both the object's mass and the strength of gravity. On Earth, a 10 kg object has a mass of 10 kg and a weight of approximately 100 N. On the moon, where gravity is 1/6 as strong as Earth's, the same object would have a mass of 10 kg but a weight of approximately 17 N. The mass of an object does not change in different locations.
