Water Pollution
Sources (litter, oil, too much fertilizer) and effects on fish, birds, and plants.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 47
- Water pollution happens when trash, oil, or chemicals get into creeks, rivers, lakes, and oceans. Rain washes litter from streets into storm drains, which empty into creeks!
- Oil coats birds' feathers so they can't fly or stay warm. Sea turtles can mistake floating plastic bags for jellyfish.
- Too much fertilizer washing into a river makes too much algae grow, and fish can't get enough oxygen.
Georgia Standards of Excellence in Science:
- S3L2.a β Ask questions to collect information and create records of sources and effects of pollution on the plants and animals.
