In this activity, students will work in pairs to create three simple types of bridges. They will observe quantitatively how the bridges work under load and why engineers use different types of bridges for different places. They also will...

This lesson focuses on the concept of Biomimicry and students learn how engineers have incorporated structures and methods from the living world in products and solutions for all industries. Students then work in teams to develop a...

This site explores the history and the science of DNA. Content also examines and considers the possibilities of genetic engineering and mutation.

For this engineering design challenge about building in hurricane-prone regions, students learn that a solid base helps stabilize a structure by constructing, testing, and redesigning a tower that can support a tennis ball at least 18...

This lesson focuses on torsion as a force acting upon structures. Students will have the opportunity to design something to withstand this force.

In this unit, students will learn about the difficulty that farmers in Bangladesh and the UK experience trying to grow crops on land that is regularly flooded. Then they will be challenged to make a model of a structure that can float to...
