b. Energy you can see with your eyes
What is energy?
A. The distance between two objects
B. The ability to cause change
C. The place where an object is located
D. The speed of an object

D. How fast an object is moving
What is energy of motion?
A. Energy an object has while it is moving
B. Energy stored for later
C. Energy that makes objects hot
D. Energy that powers only light bulbs
A. Energy an object has while it is moving
What is electricity?
A. The speed of an object
B. A type of energy you hear
C. A form of energy that powers devices
D. Energy stored in a rock
C. A form of energy that powers devices
What does it mean to convert energy?
A. To stop energy from existing
B. To change energy from one form to another
C. To measure the distance energy travels
D. To keep energy stored forever
B. To change energy from one form to another
How are energy and speed related?
The faster an object moves, the more energy it has.
What is motion?
A. The process of an object changing position
B. Energy that makes things hot
C. Energy that powers devices
D. Something that stays still
A. The process of an object changing position
Which is an example of a form of energy?
A. Sound
B. Distance
C. Position
D. Speed
A. Sound
What is energy transfer?
A. When an object becomes farther away
B. When an object stays in the same position
C. When energy is destroyed
D. When energy moves from one object or place to another
D. When energy moves from one object or place to another
8. A flashlight uses batteries to produce light. What happens to the energy in the battery?
A. It disappears
B. It is transferred and changed into other forms of energy
C. It turns into water
D. It stays inside the battery forever
B. It is transformed and changed into other forms of energy
What evidence shows that sound transfers energy from one place to another?
Sound transfers energy because it can make other objects move, shake, or vibrate when it hits them.
What is evidence?
A. Anything that helps prove or disprove an idea
B. A type of energy you can hear
C. How fast something moves
D. Energy stored for later
A. Anything that helps prove or disprove an idea
What is sound?
A. A type of energy you can hear with your ears
B. A type of energy you can see
C. Energy stored in food
D. The distance between objects
A. A type of energy you can hear with your ears
What is distance?
A. How fast an object moves
B. Where an object is in space
C. How far apart objects are
D. The energy in a moving object
C. How far apart objects are
What energy transformation happens when a flashlight is turned on?
a. Chemical energy --> light energy
b. Light energy --> chemical energy
c. Sound energy --> heat energy
d. Heat energy --> motion energy
a. Chemical energy --> light energy
What evidence shows that light, heat, and electricity transfer energy from place to place?
Evidence that light, heat, and electricity transfer energy from place to place comes from everyday observations where energy moves from a source and causes a change somewhere else.
What is an object’s position?
A. How fast it is moving
B. Where it is in space
C. How hot it is
D. How much sound it makes
B. Where it is in space
What is heat?
A. The speed of an object
B. Energy that can only be seen
C. The position of an object
D. Energy that makes things hot
D. Energy that makes things hot
2. Which example shows heat energy being transferred?
A. A ball sitting on the floor
B. A cold spoon placed in hot soup becoming warmer
C. A book sitting on a desk
D. A rock sitting outside
B. A cold spoon placed in hot soup becoming warmer
Which energy transformation occurs when you eat food and then run?
a. Sound energy --> chemical energy
b. Chemical energy --> motion energy
c. Light energy --> sound energy
d. Heat energy --> light energy
b. Chemical energy --> motion energy
How do energy transformations help people?
Energy transformations help people by changing energy from one form into another so we can use it to power our daily lives, cook food, and stay warm.
An energy transformation is when energy changes from one type to another. Energy cannot be made or destroyed, but it can change shape to help us do things.
What is stored energy?
A. Energy that is always moving
B. Energy that has the potential to cause change later
C. Energy that can only be heard
D. Energy that disappears quickly
B. Energy that has the potential to cause change later
