Collect ten rock samples from your garden or yard. Using a magnifying glass, observe
the rocks. Create a grouping of the rocks based on your observation. Label your rock
samples as samples 1 to 10. You may use the data table below for your observation.

Guide Questions:
1. How many groups did you form for your collected samples of rocks?
2. What basis of grouping or classification did you use?
3. Can you describe the common features of each group?
