Use these superheroes pictures to explore the properties of materials including strength, elasticity, hardness, toughness, waterproof, feeling, and magnetism. I have included cards which feature heroes made of sand, stone, elastic, plastic, copper, gold, glass, wood, water, sponge, iron, paper, bricks and fire. Also includes a vocabulary list to support understanding and discussion. Complete the cards by giving each character a score out of 100 in each of the categories relating to properties. Then play against each other to see who can collect the most cards. Brilliant for scientific discussion, vocabulary development, cooperative learning and independent discovery.
