Teach Engineering: Hot Stuff!
Students observe demonstrations, and build and evaluate simple models to understand the greenhouse effect and the role of increased greenhouse gas concentration in global warming.
TeachEngineering
Teach Engineering: Battling for Oxygen
Using gumdrops and toothpicks, students conduct a large-group, interactive ozone depletion model. Students explore the dynamic and competing upper atmospheric roles of the protective ozone layer, the sun's UV radiation and harmful...

Teach Engineering: Washing Air
Students observe and discuss a simple model of a wet scrubber to understand how this pollutant recovery method functions in cleaning industrial air pollution.
TeachEngineering
Teach Engineering: Engineering Pop Ups
Students learn about applied forces as they create pop-up-books - the art of paper engineering. They also learn the basic steps of the engineering design process.
TeachEngineering
Teach Engineering: A Shot Under Pressure
Students use their understanding of projectile physics and fluid dynamics to find the water pressure in water guns. By measuring the range of the water jets, they are able to calculate the theoretical pressure. Students create graphs to...
TeachEngineering
Teach Engineering: Population Density: How Much Space Do You Have?
Students learn about population density within environments and ecosystems. They determine the density of a population and think about why population density and distribution information is useful to engineers for city planning and...

Teach Engineering: Biodomes Engineering Design Project: Lessons 2 6
In this lesson students learn about biodomesand how engineers use them. Students then create their own biodomes.
TeachEngineering
Teach Engineering: Plant Cycles: Photosynthesis & Transpiration
What do plants need? Students examine the effects of light and air on green plants, learning the processes of photosynthesis and transpiration. Student teams plant seeds, placing some in sunlight and others in darkness. They make...
TeachEngineering
Teach Engineering: Biomimicry: Natural Designs
Students learn about biomimicry and how engineers often imitate nature in the design of innovative new products. They demonstrate their knowledge of biomimicry by practicing brainstorming and designing a new product based on what they...
TeachEngineering
Teach Engineering: Prosthetic Party
Student teams investigate biomedical engineering and the technology of prosthetics. Students create a model prosthetic lower leg using various materials. Each team demonstrate its prosthesis' strength and consider its pros and cons,...
TeachEngineering
Teach Engineering: Sticks and Stones Will Break That Bone!
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...

Teach Engineering: The Artificial Bicep
Young scholars learn more about how muscles work and how biomedical engineers can help keep the muscular system healthy. Following the engineering design process, they create their own biomedical device to aid in the recovery of a...
TeachEngineering
Teach Engineering: Measuring Our Muscles
Student teams build model hand dynamometers used to measure grip strengths of people recovering from sports injuries. They use their models to measure how much force their classmates muscles are capable of producing, and analyze the data...
