The learning connection
Hands-on activities like this engage students and make learning memorable. Experimenting with materials enhances understanding of scientific concepts.
Try it with your learner
1. Cut two sheets of A4 paper into strips, each 5 cm wide. 2. Use one sheet to create a base for your bridge. 3. Tape the strips together to form an arch or beam shape. 4. Place your bridge between two surfaces, like books or boxes. 5. Gradually add weights, like coins, in the middle of the bridge. 6. What did you notice about the bridge's strength as you added weight?
