Today's Problem

Brainstorm ways the following materials could be tested. This will help you design tests when planning what materials to use for the development of your engineering task. 

Think about how you could measure the strength to get a quantitative (measurable) result.

Items for testing:

• How much force is required to break a rubber band
• Compressive strength of a cardboard toilet roll (i.e. crushing a toilet roll tube)
• Load testing of a piece of chalk (i.e. snapping a piece of chalk)
• Voltage across a circuit
