Learners see that a carrot slice sinks in fresh water and floats in saltwater.

In this activity, learners separate materials based on their special properties to mimic the way recyclables are sorted at recycling centers.

Learners add different liquids (water, salt water, alcohol, and detergent solution) to water and observe the different ways the different liquids combine with water.

In this activity on page 12 of the PDF (Rethinking the 3 R’s: It’s Easy to be Green), learners examine how recyclable materials are separated by various properties at recycling centers.
