Building with sand
What type of sand was best for making a molded sand castle?
Your child can learn a lot about the characteristics of natural materials by manipulating and building with mixtures of sand, dirt, water, and other natural items he finds in the environment. Give your child some water, several buckets and a spoon for mixing, and invite him to build tiny houses for real or imaginary creatures. Encourage him to experiment with different combinations of dirt, sand, and water to find the combination that makes the sturdiest structure. How can rocks and other materials like sticks, twigs, and grass be used to help support the structure?
