Add to list Go to activity
In this activity (pages 13-14), learners investigate the properties of smart materials, which are materials that respond to things that happen around them. In this activity, learners will use Nitinol’s shape memory properties and the properties of Nitinol’s two phases to make a sculpture that can lift weight (pennies). Safety note: Young learners should have adult supervision. [Activity is publicly available through a web crawler capture on Archive.org.]
