Go Public: Osteoporosis Brochure
Osteoporosis and family — notice the connection between the two. Pairs develop a brochure to educate the public about osteoporosis in the last portion of the six-part series. The teams draw on the information learned throughout the...
Teach Engineering
Magnetic or Not?
The class must determine the magnetic properties of different materials, including aluminum and steel by sorting through materials using a magnet. Groups make a prediction on whether a material is magnetic and then perform...
Teach Engineering
Circuits and Magnetic Fields
Have your class use compasses to try to find the magnetic field around an electric current. Groups use the same technique to visualize magnetic fields as they did in the second activity in the series, but this time, the field is...

Energy Storage Derby and Proposal
Small groups use the engineering design process to build and test a vehicle capable of carrying 250 grams a distance of five meters. The design must allow for the storage of potential energy and turn it into motion,...
Teach Engineering
Linking Sources and Pollutants
Class members use an air quality monitor to measure the amount of gas-phase pollutants emitted by different sources. Groups choose three different sources and make predictions about what the monitors will detect. Teams then expose...

Writing and Research Using Counterclaims
Introduce your high school scholars as to how to use counterclaims in argument writing. Learners explore this skill with collaborative efforts and technology. Together they explore the pros and cons of homework and develop a thesis for...
Teach Engineering
Cartesian Diver
Amaze your scholars with an activity that uses a Cartesian diver to demonstrate Pascal's Law, Archimedes' Principle, and the Ideal Gas Law. Groups then repeat the process and make their own diver move up and down in a bottle.
Teach Engineering
Rock and Boat
Present the class with a question on whether the water level of a pond will rise they take a large rock out of a boat and drop it into the pond. Groups come down on all sides of the question and try to justify their answers. The activity...
