Peat like a sponge

Students check how much water peat retains compared to sand and soil.

Steps

1. We pour equal amounts of peat, sand, and soil into three funnels with a filter.
2. We pour the same amount of water in and measure how much leaks into the cup.
3. Students record the results in a table.
4. Conversation: what happens to water when wetlands are drained?

Tip: You can buy peat at a garden store; one small bag is enough.

Materials needed

• Peat (1 bag 5 l)
• Plastic funnels (3 pieces)
• Measuring cup (3 pieces)
