The Jensen Bar - What is It and How to Make One

What's the best way to learn how watersheds work? Build one! Combining engineering, the water cycle, and ecology concerns, the activity is the perfect fit for an interdisciplinary unit. Teams construct a model watershed with simple...

Host a design challenge of Olympic proportion! Junior engineers build their own bobsleds using simple materials. The activity focuses on kinetic and potential energy and how the center of mass affects motion on a downhill track....

Can't build a cantilever? You'll be able to after a hands-on, constructive activity. Young engineers build cantilevers out of straws and tape. The finished products must be able to hang off a table as far as possible.

Future engineers design and build structures out of toothpicks and marshmallows. They then make sure the structures can withstand an earthquake simulator!

An important part of balancing caloric intake to energy expenditure is knowing how many Calories you are consuming. In the fifth of a seven-instructional activity series on food and energy, learners estimate their daily caloric intake,...

Raise children's awareness about the importance of conservation with this hands-on science lesson. Start by breaking the class into groups and having them collect trash from around the school or local park. Students then use the provided...

Shake, rattle, and learn! Future engineers build structures out of toothpicks or spaghetti sticks, using marshmallows as connectors. They then use a homemade shake table to test the sturdiness of their creations.

Collaborative earth science groups create a working model of a watershed. Once it has been developed, you come along and introduce a change in land use, impacting the quality of water throughout their watershed. Model making is an...

Here is a six-minute video of a pair of electrical engineers that illustrate how to build a wind turbine. A list of materials is provided, along with general guidelines for your class. Use this to introduce turbine design to your...

Forget your local meteorologist — build your own barometer and keep track of the weather with an activity that provides directions to build a barometer out of a narrow necked bottle, a glass, and some water. Using their barometer,...
