Sometimes we all need a helping hand. Scholars get together to lend a hand in creating an assistive device that must be able to grab a hard-to-reach object. Now that's some help we could all use!

If a ski lift had rockets, imagine how fast it would be! Scholars let their imaginations take flight as they build models for such a ski lift. Rather than using a rocket, though, they'll use a much safer balloon as the power source.

Wheeeee! Young thrill seekers build a bungee jump—not for themselves, though, but for an egg. The egg must fall from a height of five feet and rebound within two inches of the ground or floor.

It's time! The fourth lesson in a five-part series has teams of scholars build a circuit for an alarm. A switch lets them turn the alarm on and off and allows them to hide the alarm—just as long as they don't hide it in the classroom!

Do your part to make manufacturing more manageable. A capstone project challenges each group to identify and research a manufacturing process for a product. To complete the activity, they create a presentation for business and community...

Biotechnology changes lives every day, but how did it all start? Learn about Cohen and Boyer's technique for recombinant DNA and the founding of this new scientific study. Then, scholars use the online interactive to discover how Hanahan...

Discover the power of wind energy. Learners design, build, and test wind blades in a hands-on experiment. They analyze the results to determine if they can make any improvements before gathering as a class to discuss their designs.

Secondary artists create a metal box made from copper tooling foil and solid oil paint sticks (Shiva Paintstiks). The exacting design develops organizational principles and the painted finish allows for individual expression of...

Blend art, adolescent snacking habits, and math to create new cereal boxes. Secondary learners review scale drawings. They use this information to construct cereal boxes to scale and will compare their creation to the original product to...

What a scam! Middle and high schoolers pose as journalists exposing consumer fraud. In this lesson, they write an article for a magazine using data collected during previous investigations (prior lessons) to defend their findings that a...

Students examine sea surface temperatures to see how hurricanes get heat from the oceans surface.  In this hurricanes lesson students use the Internet to find data and make line plots. 

Learners investigate how solar energy is converted into heat in part two of the 10-part Discover Your Changing World series. They build and test homemade solar cookers to boil water and cook rice. Pupils consider the impact of heat...

Watch red cabbage juice turn green. Pupils first watch a video that takes them through the process of creating red cabbage juice. They then add various solids and liquids to the juice and use the color change to determine whether the...

Hurricanes are a destructive yet fascinating phenomenon. Individuals examine evidence that hurricanes use thermal energy from the ocean as they approach land. Learners use images, charts, and graphs to collect data and then draw...

Students examine human anatomy by creating a prosthetic limb.  In this medical engineering lesson, students view numerous images of prosthetics used in science today and define several medical terms associated with prosthetics....

Students investigate how engineers use different types of bridges for different places. In small groups they design and construct bridges for three different scenarios, and answer a series of investigating questions applied to the...

Learners solve real life scenarios using algebra. In this word problem lesson, students use different websites dealing with engineering as it relates to the real world and math. They use other resources such as magazines to solve word...

Students explore the ways that engineers study and harness the wind. They study the different kinds of winds and how to measure wind direction. In addition, students learn how air pressure creates winds and how engineers build and test...

Students examine the concepts of computer and mechanical engineering. They dissemble a computer mouse and create a new design for the mouse. They also design new enhancements for the mouse over time.

Students examine interactions within the environment and environmental engineering careers. They discuss and view photos of natural and manmade environments, explore various websites, create a web to identify interactions between living...

Young scholars follow the steps of the engineering design process to meet the challenge of getting their entire class from one location on the playground to the sidewalk without touching the ground between. The class develops a well...

Middle schoolers examine how environmental engineers determine possible sites for drinking water wells. They listen to a teacher led-lecture, and create their own groundwater well model using a coffee can and wire screening, observing...

Young scholars explore an important role of environmental engineers by studying the Exxon Valdez oil spill. They experiment with different strategies in order to clean up their own manufactured oil spill.

Students study the concepts of weight and drag while making paper helicopters. They measure how adding more weight to the helicopter changes the time for the helicopter to fall to the ground. They apply what they examine to the work of...
