Learning objective

Explain and practice energy transfer using the activity and evidence, then take part in a grade-appropriate discussion.

Gather your materials

  • Paper and drawing supplies
  • An adult-prepared safe observation setup or photographs

Use the items named in the teaching steps; paper models or adult-prepared photographs can replace physical equipment.

Supporting Common Core connection

SL.4.1

Prepare, carry out discussion roles, link comments, and review shared ideas.

Code and grade verified 2026-11-03. This mini-lesson addresses a selected skill, not the entire standard. The connection is to the guided literacy discussion; it does not establish alignment with this subject’s content standards.

Teach it step by step

  1. Place two safe balls on a level clear surface.
  2. Roll one gently into the other and observe both before and after contact.
  3. Record the motion as evidence rather than an unseen measurement of energy.
  4. Use agreed discussion roles, explain evidence and build on a partner's idea.
  5. Discuss your evidence, follow agreed roles, and build on classmates’ ideas. Give each person a turn, invite a question, and finish by naming an idea heard from someone else.

Watch, notice, discuss

After watching

Describe a collision. What evidence suggests that energy transferred between the objects?

Make the thinking visible

Example to work through together

A resting ball beginning to move after contact is evidence of energy transfer from the moving ball; no exact energy amount is established.

Try the starter activity

Roll a ball gently into another ball. Record the motion before and after contact. Then discuss your findings with a partner or adult, using the discussion goal above.

Student practice

Repeat a gentle collision and draw arrows showing observed motion, then discuss evidence.

Quick check for understanding

What evidence suggests energy transferred?

Sample answer and teacher guidance

Sample answer: The initially resting ball moves after contact. Listen for a distinction between observation and explanation.

Listen or look for: The initially resting ball moves after contact. Listen for a distinction between observation and explanation.

Invite the learner to explain, demonstrate, draw or dictate their reasoning. Revisit a teaching step when the explanation is unclear.

Make it work for your learner

A little more support

Use a video or adult demonstration and a before/after chart.

An additional challenge

Predict how a changed starting motion may affect the outcome and discuss a fair test.
