What is Energy?
Energy is the ability to cause motion or create change. Energy is the ability to do work. Energy is everywhere you look.

Name one example of position and motion in our school.
Some examples include... ladies doing dishes in the kitchen, Ms. Sendi mopping the tile, child picking up a ball, man mowing the lawn, leaves moving in the breeze, or a car driving on the street.

When a ball falls to the ground, it's pulled down by what force?
Gravity
100
Magnetism is...
the pull of an object to a magnet

Where does heat/thermal energy come from? Give an example.
The sun radiates light and heat energy. It helps plants to grow.
200
In order to start a motion, what must be applied?
Force – push or pull
200
Is the gravitational pull the same for all objects?
Yes, objects with different masses will hit the ground at the same time (as long as an object is not “fighting” against gravity with lighter objects).
200
How are magnets that attract and repel similar? Different?
Similar – both forces Different – attraction is pulling toward itself; repelling is pushing away an object
300
Where does sound energy come from? Give an example.
Sound energy comes from vibrations. Your voice, music, and instruments are example of sound energy.
300
Define and give an example of position.
Position is an object's location, or where it is. Examples will vary.
300
How did our demonstration of a key and penny show gravity exists?
Gravity is pulling down on both objects.
300
How can you float four ring magnets on your pencil to show magnetism and gravity as non-contact forces?
By putting the same poles of a magnet next to each, the magnets will repel (push away). Although gravity is pushing them together, the magnetic force is stronger than the gravitational pull.
400
What is mechanical energy? Give an example.
Movement of an object from one place to another is mechanical energy. Some examples of this type of energy are sweeping, pulling a wagon, or walking.
400
Define and give an example of motion.
Motion is a change in position. Examples will vary.
400
What might happen on Earth if there wasn't gravity?
Everything would float if it wasn't attached to the earth.

How did Task One from “Floating Magnets” show magnetism?
The three magnets were held at the bottom by a direct contact by the attractive magnetic force.
500
What is light energy?
Light energy is energy we can see. Light bulbs, flashlights, lamps, and the sun are all examples of light.

Explain how the position of the soccer ball changed as you played the game outside. Be sure to include how the action of your foot caused the change. Use the following vocabulary words: direction, move, opposite, position, push, and pull.
Example: The position of the ball was in front of my foot. As my leg made a motion, pulling back, and then pushing forward, the ball was contacted by my foot. I kicked the ball at at angle, in the direction of the farthest cone. The ball moved with little fiction across the grass.

Why does the moon stay in its path around the Earth?
The moon is drawn toward Earth by gravity. All of the planets circulate around the sun because the sun's gravitational pull is much stronger than Earth's, the moon's, or any other planet.
500
What evidence did you see that the force of gravity was greater for the bottom magnets than the top ones in Task Three?
The spacing was smaller between the magnets on the bottom than it was for the ones on the top. The weight of all four magnets pushed down on the bottom magnet, even though the magnets were not in direct contact.
