Students will use a square to investigate other polygonal shapes that can be formed. Students will work with these polygons to make designs that will later constitute cooperatively designed quilts. The quilts will be made by translating,...

Working as engineering teams, students design and create model beam bridges using plastic drinking straws and tape as their construction materials. Their goal is to build the strongest bridge with a truss pattern of their own design,...

Students will use two different methods to determine the densities of a variety of materials and objects. The first method involves direct measurement of the volumes of objects that have simple geometric shapes, while the second uses the...

In this engineering science fair project, students will determine which 3-D geometric shapes scatter light the most. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction,...

This is an interesting project that explores which geometrical shapes make the strongest bridge truss structures. It is a good introduction to the engineering design process. You'll design three different trusses, and use online...

Using simple geometric shapes cut out of paper and taped together to create a ball that is as round as possible with this challenge. This page also includes a lesson plan, tips, and a place for students to document their engineering...
