If your student comes home with muddy knees, please forgive them. We were working diligently on creating erosion models and had to get down on the ground in order to make them work. Scientists use models to study processes that happen too slowly or on too large of a scale to observe directly. And so, working in small trays with mud, water, rocks, toothpicks, and spray bottles works well for us to "see" erosion first hand. We created deltas, carved caves, and smoothed out mountain tops all within a 30' by 15' space and in only 45 minutes! Ask your student how they eroded today.
