Determining Densities
Don't be dense—use a robust resource. The second installment of a five-part Floaters and Sinkers unit has learners determine the densities of several objects. As part of the activity, they learn the displacement method for finding...
Teach Engineering
Egg-cellent Landing
The classic egg-drop experiment gets a new bounce with an activity that asks pairs to design a lander similar to one used to land a rover on Mars within a fixed budget. The activity provides a great introduction to the idea of terminal...

Energy Systems
Is electricity created in the outlet? Using posters of several energy systems, collaborative groups identify and describe the parts of their systems. The groups also look at the environmental impacts of the systems and present their...
Teach Engineering
Working Together to Live Together
Whose home is it anyway? Design teams plan a housing development in which they must also protect a native species. The teams consist of a project manager, civil engineer, environmental engineer, and graphic designer. Teams present their...

A Simple Solution for the Circus
Class members are challenged to design a device that will move a circus elephant into a train car. Groups brainstorm ideas that use simple machines to load the elephant. They then choose one of their ideas, sketch a plan, and present it...
Teach Engineering
Machines and Tools (Part 2)
Which pulley system will give us a whale of a good time? Teams compare the theoretical and actual mechanical advantages of different pulley systems. They then form a recommendation for how to move a whale from an aquarium back to the ocean.
Teach Engineering
The Magician's Catapult
Class members work in pairs to build a catapult to launch a grape a given distance. The catapult project, a compound machine, reinforces pupils' understanding of simple machines.

Engineering Brainstorming
Here is a lesson that offers a great hybrid of forming new skills and using current knowledge to come up with a plan. The class brainstorms information they would need to know or already know about hybrid vehicles. They then group the...
Teach Engineering
Energy and the Pogo Stick
Let your class bounce to examine the concept elastic potential energy. Individuals bounce on a pogo stick in order to calculate its elastic potential energy. Groups then compare the elastic potential energy to the gravitational potential...
Teach Engineering
Energy Storage Derby and Proposal
Small groups use the engineering design process to build and test a vehicle capable of carrying 250 grams a distance of five meters. The design must allow for the storage of potential energy and turn it into motion, allowing the...
Teach Engineering
Bridge Types: Tensile and Compressive Forces
Bridges rely on tension and compression to keep them standing. Pairs test this principle by constructing simple bridges and applying a force to the center. Teams use the provided worksheet to record their observations of the reaction of...
Teach Engineering
Straw Bridges
Pairs work as engineering teams to design and build model bridges from drinking straws and tape. In this third segment in a series of 10, teams compete in an attempt to build the strongest bridge. To help with the design, the groups...
Teach Engineering
Load It Up!
See how a marshmallow can hold up a bridge load. Teams take a closer look at the design of bridge piers. They determine the types of loads that might affect a bridge, and, using that information, they calculate the needed cross-sectional...
Teach Engineering
Cost Comparisons
Our final proposal for the cost of the bridge requested is ... In the last segment in a series of 10, pairs work together to develop a proposal for a city bridge design. The class completes a cost comparison between concrete and steel to...
Teach Engineering
The Challenge Question
A research position becomes a modeling job. The introductory lesson in a series of nine presents the challenge of analyzing a set of bivariate data. The class brainstorms what the data may represent. Pupils must decide what is needed to...
