Science Bridge Challenge

Continuing with our unit on Forces acting on Structures and Mechanisms, my students engaged in interactive activities that allowed them to be able to:

- identify internal forces acting on a structure (e.g., compression [squeezing], tension [stretching]), and describe their effects on the structure
- identify external forces acting on a structure (e.g., the weight of people and furniture in a classroom, wind blowing on a bridge etc.)
- use technological problem-solving skills to build and test a frame structure ( a bridge) that will withstand the application of an external force (500 grams).

Here are the pictures. I'm sure you'll agree they did an AMAZING job!
