Rocks and Minerals Hardness Test Pfart 2

So yesterday we began our hardness test and conducted four different trials to see the hardness of the rocks and minerals we tested.  Today we completed day 2 which was the vinegar test.  We made our prediction of the results based on the results from yesterday, so we can continue learning base our "arguments" and ideas on real data and not just guessing.  Our discoveries today have created some new wonderings!
