What children learn in Level 49
- Scientists keep records to learn about pollution. One way is a litter survey: walk an area, and tally each kind of litter you find.
- Then make a bar graph to compare. Here, food wrappers were the most common litter.
- Records help people make good choices, like adding trash cans where wrappers pile up.
- Try it with a grown-up: wear gloves and do a litter survey of your yard, a park, or your schoolyard. Tally what you find!
Georgia Standards of Excellence in Science:
- S3L2.a — Ask questions to collect information and create records of sources and effects of pollution on the plants and animals.
