No

200

Complete the sentence:

Energy moved from the ______ to the ______.


Battery pack → phone.

200

What is evidence?


Information that supports your answer.

300

True or False: An object can have energy even when it is not moving.

True

300

Why did Mila's phone begin playing music again?

Energy transferred from the battery pack to the phone.

300

Which is the BEST evidence that the phone did not have enough energy to keep playing music?

A. Mila ate a banana
B. The music stopped
C. Mila went running
D. She wore headphones

The music stopped

300

Why did the phone start playing music again?

A. The phone created energy.
B. Energy transferred from the battery pack to the phone.
C. The headphones gave the phone energy.
D. Mila's running charged the phone.


B. Energy transferred from the battery pack to the phone.

300

Reasoning : 

“Based on the evidence, ______.”

Based on the evidence, the phone needed energy because it started playing again after Mila connected the battery pack.”

400

Mila eats a banana before running. Does the banana contain energy?

Yes. The banana contains stored energy that Mila's body can use

400

After Mila plugged her phone into the battery pack, did the energy stored in the battery pack increase, decrease, or stay the same?

Decrease

400

Complete the sentence:

“I know the phone did not have enough energy because ______.”

The music stopped playing.

400

After giving energy to the phone, did the amount of energy in the battery pack:

A. Increase
B. Decrease
C. Stay the same


B — Decrease.

400

"This matters because ______.”

…it shows that energy transferred from the battery pack to the phone.”

500

Explain the energy change when Mila eats food and then runs.

Stored energy from the food is transferred to her body and allows her body to move, producing kinetic energy.

500

Give a complete scientific explanation:

The battery pack's energy decreased.
What evidence and reasoning support this claim?

Evidence: Mila's phone began playing music after she connected it to the battery pack.
Reasoning: The phone needed energy to operate. Since energy transferred from the battery pack to the phone, the amount of stored energy in the battery pack decreased.

500

Which is the stronger answer?

A. No.
B. No. My evidence is that the music stopped playing.


B. No. My evidence is that the music stopped playing.


500

Why did the battery pack's energy decrease?


Because energy transferred from the battery pack to the phone.

Question: Did the battery pack loose some of its stored energy ? 

Claim:The battery pack lost some of its stored energy.

Evidence:The phone started playing again after Mila connected the battery pack.
Reasoning: This matters because energy transferred from the battery pack to the phone, so the battery pack had less stored energy.
