Sun, Moon, and Earth
True or false, the sun rotates around the Earth.
False
Name the three steps of the water cycle.
Evaporation, condensation, and precipitation.
Name the three states of matter.
What are solid, liquid, and gas.
Who developed the Laws of Motion?
Who is Sir Isaac Newton
What is transferred from organism to organism in a food web?
Energy
How long does it take the Earth to make on complete rotation around the sun?
What is 365 days or one complete year.
When water is evaporated it becomes what
Water vapor
Which state of matter has a defined volume but not a defined shape?
Liquid
What is the force that acts when two objects rub together.
Friction
In a food web, what is the job of the decomposer?
They break down the remains of consumers to nourish the soild for producers.
Use three people in your group to demonstrate the orbit of the sun, moon, and earth.
One person should be standing still in the middle, the sun. Another should be walking around the sun while rotating, the earth. The last student should be rotating around the earth while spinning, the moon.
When they are warmed by the sun they evaporate when they are condensation the molecules are being cooled.
Materials change states of matter by adding or removing what
Heat
Define gravity.
The force that pulls things toward the center of the Earth and keeps them from floating away.
Explain the difference between a food chain and a food web.
A food web has multiple paths of energy while a food chain has only one path of energy through an ecosystem.
Explain why a shadow would increase then decrease in length throughout the course of a day
The sun is crossing the sky so it is hitting the object from which the shadow is being cast at different points throughout the day
Your entire group must sing the water cycle song.
Good job!
What state of matter has no defined shape or volume.
What is gas.
Name one law of motion.
1. An object at rest will remain at rest unless a force acts upon it. 2. An objects motion depends upon its mass and the amount of force needed to move that mass. 3. For every force or action there is an equal and opposite reaction.
Explain what would happen in a food web if a second level consumer was killed off and removed from the ecosystem?
The third level consumers would not have food to survive and would starve or relocate and the first level consumers would overpopulate, run out of food and starve or relocate.
How long does it take for the moon to orbit the Earth?
27-28 days
Once water precipitates from a cloud, where can it go form there?
It can be evaporated back up, be absorbed into the ground and become groundwater, or travel into a larger body of water.
Explain what the molecules in each state do. (i.e. move freely, shake, etc.)
The molecules in a solid vibrate in place, molecules in a liquid shake and have minimal movement, molecules in gas move freely past each other.
Potential- energy stored for later use.
Kinetic- energy in motion or use.
Example: roller coaster at top, in motion. Bat being held, then swung.
Define carnivore, herbivore, and omnivore.
Carnivore- organism that eats only meat
Herbivore- organism that eats only plants
Omnivore- organism that eats plants and animals.
