Milli's Super Sorting Challenge

In this activity, learners separate materials based on their special properties to mimic the way recyclables are sorted at recycling centers. Learners observe if various objects are attracted to a magnet, are attracted to a balloon, and float on (or sink in) water. Use this activity to discuss recycling as well as magnetism, static electricity, cohesion and density.
