There’s nothing better than playing with sand in the classroom! Your students can be construction engineers experimenting with sand to see which combination of materials makes the strongest sand castle. Help them understand that different combinations of materials will affect the outcome of the building. This lesson includes objectives, a materials list, an introduction into the reason for the process, as well as several assessment suggestions. Practical applications of engineering problems are not often addressed in grades 3-5, but this lesson is aimed just at that age group and is a great way to interest your students in science and engineering.
