Worksheet 1
1A toy car moved 3 m/s in Trial A and 8 m/s in Trial B. Which claim fits the evidence?
2A soccer ball rolls toward a target. What prediction follows from the speed data?
3When the moving rubber ball hits another object, what happens to energy?
4Which evidence best supports the claim "the faster marble has more energy of motion"?
5Which fair test would compare energy of motion for the cart?

About this worksheet
Energy and motion investigations show that moving objects have energy and that speed affects what happens in a collision asks fourth graders to connect observations with an explanation, model, or design decision instead of choosing a fact from memory. Students may say a heavier or larger object always has more motion energy even when the evidence is about the same object moving at different speeds. This worksheet uses short investigations and evidence-based situations so students must read what happened, decide which science idea is being tested, and choose the answer that fits the title. Students compare speeds, predict collision effects, interpret energy transfer, and use bar-graph evidence from motion tests. Support versions use familiar objects and direct wording. Standard and challenge versions add closer distractors, fair-test language, and multi-step evidence. Ask your child to point to the measurement, diagram, map, or observation before answering. If the choice does not explain the evidence in the prompt, it is probably a distractor. That habit keeps science reasoning tied to data rather than guesswork.
What your child will learn
Relate speed to energy of motion
Predict collision outcomes
Use evidence from motion tests
Describe energy transfer between objects
Worked example
If the same cart rolls faster in one trial, the faster cart has more energy of motion and may push a cup farther.
Common mistake
Ignoring speed data and choosing the biggest-looking object instead.
Helpful hint
Compare the speeds first, then predict the collision result.
