Physical Science
It is what makes up matter.
What are atoms or molecules?
In this food chain the grass is the example of this.
Grass → Caterpillar → Bird → Snake
What is a producer?
This is where most of the water on Earth is located.
What is the ocean?
This causes day and night on Earth.
What is the rotation (spinning) of Earth?
Salt dissolving in water, peanut butter mixed with jelly, and a candy bar melting are all examples of this.
What is a physical change?
This is an animal that eats plants and animals.
What is an omnivore?
Lava from a volcano destroys trees and vegetation in its path is an example of these two spheres interacting.
What is geosphere and biosphere?
This causes the seasons on Earth and causes Earth to see different constellations throughout the year.
What is the orbit (revolution) of Earth?
Food digesting, fireworks exploding, and iron rusting are all examples of this.
What is a chemical change?
This is not a complete food chain because this is missing.
Grass → Caterpillar → Bird → Snake
One of the ways people can help the geosphere.
What is reuse, reduce, or recycle?
This is why the sun looks bigger and brighter than other stars.
What is the closeness of the sun to the Earth?
A gas forms and heat is produced when two substances are mixed showing this type of change.
What is a chemical change?
This is the type of food plants make during photosynthesis.
What is sugar or glucose?
Animals breathing in oxygen and breathing out carbon dioxide is an example of these two spheres interacting.
What is biosphere and atmosphere?
This is why we don't fall off of Earth.
What is gravity?
Water in a bowl has a mass of 25 ml. After it is frozen its mass still measures 25 ml showing this.
What is conservation of matter (conservation of mass)?
This is what plants use along with sunlight and water for photosynthesis.
What is carbon dioxide?
This is where most of the fresh water on Earth is located.
What are glaciers?
This is the time of day shadows are the shortest.
What is noon?
