Our rocks and minerals unit is in full swing, and this week students are putting rocks to the test in our very own Rock Olympics! Students tested the physical properties of various rocks and minerals to see which rock would win the gold at each station. We tested for hardness using the Moh’s Scale, examined the impact of water on colour, studied the weight of rocks, and determined which rocks or minerals are the most useful. Students showed gold-medal teamwork as they judged our “rock-star athletes!”
