Rocks are natural, solid nonliving material found in the earth.
Rocks are made of minerals.
Rocks change during the Rock Cycle.
There are 3 main types of rocks
Igneous rocks form from melted magma or lava that has hardened and cooled.
Sedimentary form from small pieces of rocky material that are pressed or cemented together.
Metamorphic rocks form when great heat and pressure change the rocks that are there.

A mineral is a solid material formed from nonliving things.
A gem is an example of a mineral valued for being rare and beautiful. (diamond, ruby, sapphire)
We can identify minerals by color, luster, (shiny or dull) streak, or hardness.
Chemicals found in some minerals keep our bodies healthy.

Soil is a thin layer of loose material that covers most of the Earth’s land.
All soil has the same ingredients, weathered rock, humus, air, and water.
There are 3 layers of soil: topsoil, subsoil, and bedrock
There are 3 main types of soil, plus LOAM. – SAND, SILT, CLAY

3/4 of the Earth’s surface is covered in water-most is salt water.
You should know at least 3 uses of water and the 3 forms-liquid, ice, and water vapor.
Know the Water Cycle, especially the words EVAPORATION-CONDENSATION-PRECIPITATION.
Fresh water is founds in groundwater, wetlands, rivers, lakes, and streams.
E. Force and Motion
1. Motion is a change in position.
2. Force is a push or pull on an object. A heavier object takes greater force to move,
3. There are 3 main types of force.
4. Gravity is a pulling force between the Earth and an object.
5. Friction is force that is created when 2 objects rub together.
6. Magnetic force is anything that attracts metal. We say it has the property of magnetism.
7. Magnets have 2 poles. Like poles repel or push away from each other. Opposite poles attract.
8. There are 3 types of motion- LINEAR, WAVE, and RANDOM.
9. Energy is the ability to do work.
10. Work is when force changes the motion of an object.
F. Simple Machines.
1. Know the 6 simple machines and 1 example of each kind.
2. LEVER, PULLEY, WEDGE, WHEEL AND AXLE, INCLINED PLANE, and SCREW
G. The Human Body
1. Cells are the basic units of all life.
2. Cells work together to perform functions.
3. The part that holds the cell together is called the membrane.
4. The nucleus tells the cell what to do,
5. Groups of cells are called tissues.
6. Groups of tissues that work together are called organs
7. Groups of organs are called systems.
8. Be able to name 4 systems.
9. Bones support and protect your body. There are 206 bones in the adult body.
10. Bone marrow produces red and white blood cells.
11. Joints are points at which bones meet. Not all allow movement.
12. Tendons join muscles to bones.
13. Ligaments attach bones to each other to hold the skeleton together.
H. Living Things
1. Know the meanings of the following words. Use your Living things Study Guide to help you.
2. ecosystem, community, population, individual, habitat, niche, food chains, producers, consumers,
food web, herbivores, carnivores, omnivores, decomposers
3. Adaptations traits that help an animal survive where he lives.
4. Mostly adaptations are needed for protection.
5. Camouflage helps an animal blend in with its surroundings.
6. Armor is a special body part that protects animals from danger.
7. Poison- an example would be snake venom
8. Mimicry- This is the ability to look and or act like a dangerous animal when the animal is harmless.
