The fifth graders continued their study on mixtures by conducting an experiment that helped them practice different filtering methods. Students were asked to filter out three different mixtures: water with gravel, water with salt and water with a mystery powder. They previously practiced paper filtering in the last experiment, so now students tried filtering using a wire mesh screen. Each step students had to observe and record their observations on texture, color and clarity of water and other interesting observations. In the end, students were asked to use their data and observations as evidence to which method they thought was most effective in filtering out each mixture.
