Forms of Energy (Basic)

Students investigate sound. They decide to apply what they have learned to make a musical instrument with materials from the kitchen. First, they locate four identical glasses. They each hold different amounts of water.

The students blow across the top of each glass and hear a sound. Which conclusion can the students draw from this finding?

• Energy has changed form

• Air is vibrating across the water

• Energy has been reflected off the water

• Air is producing energy

Students decide that the amount of air in the glass is related to the pitch of the sound produced. What observation would support the conclusion that the more air that vibrates, the lower the pitch?

• All of the glasses make a sound of the same pitch

• Only the glasses that are at least half-full make a sound

• Glass 4 makes the highest pitch

• Glass 2 makes a higher pitched sound that glass 3

A guitarist strums two strings on her guitar. The first string vibrates more quickly that the second string. What is true about the pitch of the strings?

• The first string has a higher pitch than the second string.

• The second string has a higher pitch than the first string.

• The strings have the same pitch.

• The pitch of the second string is louder than the pitch of the first string.

Look at the diagram of the melting popsicles.

What do the arrows MOST LIKELY represent?

• Heat energy transferring from the air to the popsicle, causing a change in state

• Light energy from the Sun transferring to the popsicle, causing particles to move faster

• Particles in the air transforming the particles in the popsicle, causing them to move faster

• Particles of energy transferring from one part of the popsicle to another, causing it to melt

Kayla and Rachel each roll bowling balls down their lanes at the same time. Both bowling balls have the same mass. Kayla’s bowling ball reaches the pins before Rachel’s bowling ball.

What can you conclude about how the bowling balls were rolled?

• Kayla exerted a greater force on the ball.

• Rachel exerted a greater force on the ball.

• Kayla’s force balanced Rachel’s force on the ball.

• Rachel did not exert a force when she rolled the ball.

In science class, a group of students put water in a pot, put the pot on the hot plate and turned on the burner to the “high” setting. After a short amount of time, the water started to boil. What is MOST LIKELY to happen if they kept applying energy to the boiling water?

• The water would condense

• Ice would begin to form

• All of the water would change to a gas

• The water would continue to boil, but would not change state.

While playing at the park, Erica and her sister take turns going down the slide and swinging on the swings. Which of the following is an example of change that is caused by applying energy?

• Erica continues to swing back and forth without trying.

• When Erica pushes her sister, her sister slides down the slide.

• Erica sits at the top of the slide and waits for her sister to finish her turn.

• When Erica stops pushing her sister on the swings, the swing eventually comes to a stop.
