How to use shadows to teach Light Energy:
- Find a plain flat surface as a screen
- Use a smart phone portable stand
- Clip and secure the smart phone on the stand
- Switch on the flashlight option (download the app if smart phone does not have flashlight inbuilt)
- Adjust the size of the light shone
- Cut out templates on pieces of paper
- Templates can be taken from clip art or hand drawn. (for this, our P6 boys drew and cut out the shapes on their own)
- Ensure the shapes are clear (like a figure of a lion, monkey, shark, etc)
- Tape the templates on wooden chopsticks/pencils
- Test out the shadow puppets against the light source
- For bigger shadows, move the puppets nearer to the light source
- For smaller shadows, move the puppets further away from the light source
