I can compare objects based on their physical properties so that I can classify matter.
I'll know I have it when I can explain that anything that has mass and takes up space is matter.

Can the popcorn be kernels of corn again? Why or why not?

​

Can you unpop popcorn?

1. observe ways the objects are alike and different. List 3 of these properties.

​​What properties can be used to classify matter?

2. Classify Observe how the objects are alike. Sort the objects into 2 groups. Put a yarn circle around each group. What property is alike for the objects in each loop?

3. Look at what other groups did. Infer three properties they used to classify their objects.

​4. How can you use properties to describe matter?

When you compare you say how things are alike. When you contrast you say how things are different.
