Teach Engineering: Bumps and Bruises

Build a strong foundation for your teaching of stability and change! The video addresses the Next Generation Science Standards Cross-Cutting Concept through insightful examples. The narrator includes ideas for introducing the standard in...

Students learn about the strength of bones and methods of helping to mend fractured bones. During a class demonstration, a chicken bone is broken by applying a load until it reaches a point of failure (fracture). Then, working as...

We design and create objects to make our lives easier and more comfortable. The houses in which we live are an excellent example of this. Depending on your local climate, the features of your house will be different to satisfy your...

Through a series of activities, students discover that the concept of mechanical advantage describes reality fairly well. They act as engineers creating a design for a ramp at a construction site by measuring four different inclined...

This lesson introduces students to the important concept of density. The focus is on the more easily understood densities of solids, but students can also explore the densities of liquids and gases. Students devise methods to determine...

Through an overview of the components of the hydrologic cycle and the important roles they play in the design of engineered systems, students' awareness of the world's limited fresh water resources is heightened. The instructional...

Students explore the use of several biomedical engineering sensor devices, and then use the collected data to create and analyze scatterplots of the different variables to determine if any relationships exist between the measured...

In this activity, students gain first-hand experience with the mechanical advantage of pulleys. Students are given the challenge of helping save a whale by moving it from an aquarium back to its natural habitat into the ocean. They set...

Students use a spring scale to drag an object such as a ceramic coffee cup along a table top or the floor. The spring scale allows them to measure the frictional force that exists between the moving cup and the surface it slides on. By...

Students are introduced to the differences between acids and bases and how to use indicators, such as pH paper and red cabbage juice, to distinguish between them.
