Sorting Materials

You have already learned about classifying objects by properties, the three states of matter, sink and float, and how materials are chosen for their purpose. Today you put it all together — by getting your hands on real objects and sorting them yourself.

What this lesson teaches

1Collect everyday objects and physically sort them by observable properties — hard or soft, transparent or opaque, sink or float and record results
2Explain each choice using correct materials vocabulary
