Avalanche Experiment

Primary 6 were learning how avalanches are caused. Weak layers of unstable snow give way when stronger layers of snow form on top.

We recreated the weak layers using rock salt and coconut and the strong layer was flour. We tipped the slope to an angle of approx. 38 degrees and watched what happened. The total contents slid off! We were hoping to see a slab give way as you would see in a real avalanche.
