Water in experiments

A series of simple experiments: what sinks, what floats, filtering, and traveling water.

Steps

1. Station 1: children guess what sinks and what floats (cork, coin, apple, plasticine) and check it.
2. Station 2: a filter made of a bottle, sand, gravel, and cotton wool cleans dirty water.
3. Station 3: traveling water - a paper towel between cups of dyed water creates a rainbow.
4. Summary: why we need to save water and how to do it at home.

Tip: Start the traveling water in the morning, the effect is visible after a few hours.

Materials needed

• Liquid food colouring (1 set)
• Reusable clear plastic cups (10-12 pieces)
• Paper towel (1 roll)
• Little scientist water kit for children (1 set (optional))
