About this worksheet

What students practice

  • Students use repeated observations to connect an object's speed with its energy.
  • Students compare fair-test results to support a claim about motion and energy.
  • Students use evidence to make cautious predictions about a moving object's effect.

How to use

Read the trail investigation together and discuss what was changed, measured, and kept the same. Then have students use the repeated results to answer the questions and write evidence-based explanations.

Pinecone Clues at a Mountain Lodge Station

Use trail-token observations to explain how speed and energy are connected.

Read the trail investigation

Read the investigation and data table. Use the evidence to answer the questions.

The Pinecone Trail Model

At a mountain lodge science station, Keira and Mateo built a model of a trail. They used the same smooth wooden trail token each time. The token slid down a packed-snow board and struck three pinecones resting in marked circles. The students counted how many pinecones moved out of their circles.

The students changed the token's speed at the start of each set. They measured the token's speed during the final second before it reached the pinecones. They used the same board, token, pinecones, and starting direction. The pinecones were placed in the same positions for each trial.

The table shows their observations. The three trials in each row used the same speed setting. The impact measurement is the number of pinecones that moved out of their circles.

Speed during final second | Impact measurement in three trials | Average impact 15 centimeters per second | 1, 1, 2 pinecones | 1.3 pinecones 30 centimeters per second | 3, 4, 3 pinecones | 3.3 pinecones 45 centimeters per second | 6, 5, 7 pinecones | 6 pinecones

1.

  • A. The wooden token's shape
  • B. The pinecones' positions
  • C. The token's speed
  • D. The snow board's length
2.

What was the average impact at 30 centimeters per second?   pinecones
