What students practice

  • Students compare information about Earth events that happen quickly or very slowly.
  • Students use time clues and observations to explain cause and effect in Earth changes.
  • Students support a claim about Earth events with evidence from records.

How to use

Read the kitchen science records aloud and trace the cause-and-effect chain together. Then have students use the records to compare event times and support their ideas.

Read the kitchen science records

The school kitchen is making a science display about where soil and rocks come from. Read the records. Then answer the questions.

Records from the School Kitchen Garden

1. After a heavy rainstorm, water ran down the slope beside the kitchen garden. In about 2 hours, the water carried soil away and left a groove 6 centimeters deep. The class marked the groove and took a picture.

2. During a storm, three rocks fell from a nearby rocky bank. A safety camera showed the rocks falling in 8 seconds. The rocks landed at the bottom of the bank.

3. The school found older pictures of a sandstone ledge. The ledge was 2 centimeters thinner in a picture taken 50 years later. Wind and rain had carried away tiny grains over many years.

4. A geology record showed that a river carried sediment away for about 200,000 years. Over that long time, the river made a valley 30 meters deeper. The valley did not become that deep during one afternoon.
