AIM

To test for the presence of water in living things.

Materials Required

1. Test tube
2. Bunsen burner
3. Beaker
4. Green plant leaves
5. White anhydrous copper sulphate

Procedure

Water in Living Organisms Science Fair Project

Heat green plant leaves in a test tube and collect the condensed vapour in a beaker as shown. Add a drop of this to white anhydrous copper sulphate.

Observation

Each specimen will be found to produce a clear liquid which turns white anhydrous copper sulphate blue. This is a test for water.
