Magic opening flowers are a brilliant super simple science investigation using just paper and water. The folded paper flowers open up as the paper absorbs the water. They are a great way to learn about capillary action and transport of water in plants too.
You can make these as simple or creative as you like. Try experimenting with different flower shapes, types of paper and size of flowers. This investigation is great preschoolers who will love to watch the flowers open to reveal a drawing inside. Older children can use it as part of a plant science unit or use it to practice correct experimental procedures.

Magic opening flowers instructions
Half fill the tray with water.
Cut out several different shaped flowers from different types of paper.
Fold the petals up.
Draw a little image inside – optional
Carefully place the flowers on the water and watch as they open up.
If you don’t want to cut out your own flowers, try my template.
Make it an investigation
Place flowers made with different types of paper onto the surface of the water at the same time. Record how long each take to open up.
Remember to make this a fair test the flowers must be the same size and placed in the water at the same time.
