Truss Me is an iPad app that students can use to design and test simple weight-bearing structures. Truss Me can be used in “challenge” mode or in “free play” mode. The challenge mode contains fifteen activities in which students are awarded points for strength and efficiency of their structures. For example, if a structure holds the weight but uses too many parts it doesn’t receive as many points as a structure using fewer parts while supporting the same weight. Structures that won’t work at all fall apart.
Truss Me is a nice iPad app that could be used as part of a simple physics lesson. I would like to see the app offer more instruction to students in terms of why a particular structure design is better or worse than another.
Simple Physics is a similar app that you might also want to try.
Both apps in this post are currently priced at $1.99
