Today is science we completed Rocks and Mineral scratch testing. We talked about Mohs hardness scale; and then we completed the scratch testing on our samples to try and figure out how hard each one was. Each group was given a collection of rocks and minerals and some scratch testing tools including: a penny, a nail, paper clip, nail file and a magnifying glass. They recorded their results in their notebooks.
I am so proud of how engaged and excited the students were today! They appeared to really enjoy this experiment.
