In this activity (pages 3-4), learners investigate the properties of smart materials, which are materials that respond to things that happen around them. This activity explores the properties of one smart material (Nitinol) by shaping and heating it. What makes Nitinol so smart? Find out! Safety note: Young learners should have adult supervision. Nitinol can get very hot when using electricity. Don’t touch the wire as it is heating. Hold the alligator clips by the insulated covers.
