Bend That Bar
Bend it, but don't break it. Groups investigate the strength of different materials. Using a procedure in the seventh segment of a 22-part series on aviation, pupils determine how far a rod will bend. They determine the strength-to-mass...

Indicating Electrolysis
Sure, your learners know water is made up of two molecules, but watching them separate helps the class see the construction like never before. This resource provides directions on how to build a simple electrolysis device using a...
Teach Engineering
Investigating Contact Angle
Discover the properties of water-loving and water-hating surfaces. In the seventh installment of a nine-part series, scholars explore hydrophilic and hydrophobic surfaces by conducting an experiment. They observe surface coatings,...
Teach Engineering
Building a Piezoelectric Generator
In pairs, learners build a piezoelectric generator from readily available electric components in the second and final installment of the two-part series. Tapping the piezoelectric element produces enough electricity to light an LED....

Build a Candy Dispenser
Everything in moderation, especially candy. Scholars design and build a dispenser for candy. But, they can't get too carried away—only three or four pieces of candy can come out of the dispenser at one time.
Teach Engineering
Exploring Capillary Action
Explore capillary action from different perspectives. In the fourth installment of a nine-part series, scholars perform several experiments to observe capillary action. They look at the meniscus of water in a glass, observe capillary...
PBS
Heart to Heart
Study heart health and math in one activity. After measuring their resting heart rates by finding the pulse in their wrists, learners build a stethoscope to listen to their heart rate, and note the differences between the two methods.
