You will find several objects in a container. Can you describe the object to your group members without telling them what
it is? Each member takes turn describing an object from the bag.
Object one: Descriptors: _______________________________________________________________________________________________
Object two: Descriptors: _______________________________________________________________________________________________
Object three: Descriptors: ______________________________________________________________________________________________
Object four: Descriptors: _______________________________________________________________________________________________
Now come up with general descriptors you can use that are unique to a particular object. Think about them as a group
and write them down. I’ve given you one to get started.

The words that you used above are how you describe matter and they are called physical properties of matter.
Brainstorm some physical changes in matter. List them in the space below:

Give an example for the following physical changes of matter.
Shape: ________________________________________________________________________________________________________________
Size: __________________________________________________________________________________________________________________
State: _________________________________________________________________________________________________________________
Chemical Properties of Matter
If physical properties are what describes an object, then what are chemical properties of matter? Look up a definition for
chemical properties of matter and write it down here in your own words:

You will see a list of some signs that signal a chemical change. Give examples of where you have seen that happen.
A gas is produced (sometimes production of bubbles is a sign):
