The students have been learning all about their five senses and the many ways in which we use our senses to explore and observe the world around us. We recently started learning about science tools that can help us as we make observations and take part in exploration. During this lab, students were asked to look at different materials and pick the one they thought would be best to use when cleaning up a liquid mess. They had to answer the question, "which material will absorb water the best?". The students made predictions and then worked with partners to explore pieces of aluminum foil, wax paper, and paper towel using water droppers and observing how each material reacted with the water. Our conclusion? Wax paper and aluminum foil would only spread the mess around. Paper towels are the best choice because they absorb liquids better than foil and wax paper!
