Cookie mining lab - Understanding why we should protect our environment from damage caused by mining
As environmental science students, we need to learn the importance of minimizing the impact of our actions on the world around us. Did you know that when miners drill into or strip the earth to obtain ore or fossil fuels, they can cause great environmental harm? In this science project, we will be operating our own "mine" to understand how mining can damage our environment . We will be mining "

Just about everything has potential energy stored in it. The problem is releasing that energy to be able to do some work.A tiny peanut contains stored chemical energy. When we eat them, the stored energy is converted by our bodies so we can do work. We can also use the energy in a peanut to heat a container of water.
