Teach Engineering: Capturing the Sun's Warmth
In the exploration of ways to use solar energy, students investigate the thermal energy storage capacities of different test materials to determine which to use in passive solar building design.
TeachEngineering
Teach Engineering: You're in Hot Water
To explore different ways of using solar energy, students build a model solar water heater and determine how much it can heat water in a given amount of time. Solar water heaters work by solar radiation and convection.
TeachEngineering
Teach Engineering: Cooking With the Sun
Students learn about using renewable energy from the Sun for heating and cooking as they build and compare the performance of four solar cooker designs. They explore the concepts of insulation, reflection, absorption, conduction and...

Teach Engineering: Oil Spill Cleanup
This hands-on experiment will provide students with an understanding of the issues that surround environmental cleanup. Students will create their own oil spill, try different methods for cleaning it up, and then discuss the merits of...
TeachEngineering
Teach Engineering: Oil on the Ocean
Students learn about oil spills and their environmental and economic effects. They experience the steps of the engineering design process as they brainstorm potential methods for oil spill clean-up, and then design, build, and re-design...

Teach Engineering: This Landfill Is a Gas!
In this activity, students work as engineers to build and observe a model landfill. They will understand the process and pitfalls of the use of landfills as a method for the waste disposal.
TeachEngineering
Teach Engineering: It's All in the Package
In this activity, students explore the concept of "reducing" solid waste and how it relates to product packaging and engineering advancements in packaging materials. Students read about and evaluate the highly publicized packaging...
