My students love this activity! It is a fabulous way to get them excited about physical properties!
This complete lesson contains an "Engage" activity introducing the Physical Properties of Matter, as well as a PowerPoint and student note taking papers to ensure engagement.
This lesson includes:
Instructions for use
"Mystery Rock Challenge" Worksheet
"Physical Properties of Matter" Worksheet
"Physical Properties of Matter" Key
"Physical Properties of Matter" PowerPoint, which explains the activity and provides answers to the "Physical Properties of Matter" worksheet.
You will need to purchase rock salt, ice cream salt, or sea salt in order to use this activity. A large box of ice cream salt can be purchased for less than $3 at a grocery store, and would be enough to complete this activity 50 or more times.
I recommend adding the notes to interactive notebooks after they are completed, though these activities easily work without using notebooks.
