Purpose: show children about how a plant absorbs water (osmosis)
Materials:
- celery stalks with leaves, if possible (my local store had all the leaves cut off)
- clear glasses or jars
- water
- food colouring
Procedure:
- Cut the bottoms of the celery stalks.
2. Fill glasses up at least halfway with water.
3. Add food colouring, about 15-20 drops. Use darker colours and more food colour drops (the sooner you’ll see results and the easier it will be to see)
4. Place celery stalks into the water.
5. Observe what happens to the celery after 24 and 48 hours.
Day 1 (after 24 hours)
Day 2 (after 48 hours)
Discuss what you see with your child.
