About this worksheet

What students practice

Students use observations and time clues to compare quick and slow Earth changes.
Students support a claim about the speed of Earth changes with evidence from records.

How to use

Read the museum records together and explain that the drawings label the records rather than show the changes. Have students use the time clues to answer, then discuss their evidence.

Earth Changes in the Camera Room

Use picture records and time clues to compare changes to Earth.

1. Follow the Rock Records

Read the records. The small drawings show objects found at each place. Use the written observations to learn what changed.

Two Places, Two Records

Imani visits the Earth Camera Room at a science museum. Scientists have shared pictures and notes from different places. Each record tells what changed and how much time the change took.

Record A: Falling Rocks
Picture of a rock
A camera on a distant hill filmed a cliff. Rocks broke loose and fell. A new pile formed below the cliff. The fall lasted 30 seconds. No people were near the falling rocks.

Record B: Stream Rocks
Picture of a rock
At a stream, moving water rolled rocks against one another. Tiny bits wore away. Scientists studied the rocks and the stream. Their notes explain that sharp corners became rounded over thousands of years. One picture shows the rounded rocks beside the water.

Which comparison do the time clues support?

A. The stream rocks rounded faster than the rocks fell.
B. The rocks fell faster than the stream rocks rounded.
C. The two changes took about the same amount of time.
D. The two changes were finished within one minute.

Underline the note that is evidence of a very slow change.

A new rock pile formed during a 30-second fall.Rounded rocks lay beside the water in one picture.A camera stood on a hill away from the cliff.Rock corners wore away over thousands of years.
