About this worksheet

What students practice

  • Students use time clues to classify Earth changes as quick or very slow.
  • Students judge whether display designs accurately show the time taken by Earth changes.
  • Students support a claim about Earth change speeds with evidence from sample records.

How to use

Read the sample records together. Let students judge the display plans, then discuss why a model's running time may differ from the time a real Earth change takes.

Curriculum

NGSS standard covered

2-ESS1-1

Choose Records for the Display

Read the sample records. Use the changes and their time clues to answer each question.

A New Display at the Zoo

A zoo is planning a learning hall beside its bat house. Visitors will explore a model cave and learn about changes to rocky land. The builders want their displays to show how long Earth changes take. They use these made-up sample records with realistic times. The records describe real kinds of Earth changes, not changes inside the zoo.

Ground crack: During an earthquake, the ground moved and a new crack opened. This change took 20 seconds.

Soil slide: Wet soil slid down a steep hill and collected at the bottom. The soil moved and came to rest in 3 minutes.

Cave mound: Dripping water left tiny bits of stone that built up on a cave floor. A stone mound grew from 2 centimeters tall to 3 centimeters tall over 100 years.

Stream valley: A stream carried away small amounts of sand and rock again and again. Records describe how the valley became much deeper over 6,000 years.
