How Photocells Work
Give small groups of physical scientists tokens that represent electrons in a photovoltaic cell. They play a dice game in which they move the tokens around, representing the flow of electrons through the p-n junction of a semiconductor...
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
Electricity and Magnetic Fields
Introduce your class to the idea of magnetic fields around electrical wires with an activity that provides the information about the direction of a magnetic field around a wire carrying an electric current.
Teach Engineering
Slinkies as Solenoids
What does an MRI machine have to do with a slinky? This activity challenges learners to run a current through a slinky and use a magnetic field sensor to measure the magnetic field. Groups then change the length of the slinky to see...

Alloy the Way to Mars
Future engineers test different alloys to determine the specific strength of each one. Based on the results, they make a recommendation to NASA on which alloy to use on engines for spacecraft.
Teach Engineering
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...

Understanding Elements
Nothing says organization quite like a table. The third lesson in a six-part Mixtures and Solutions unit teaches young scientists about elements and the periodic table. They learn how the periodic table is organized and about the...
Teach Engineering
Gumdrop Atoms
There's nothing sticky about the resource, unless you count the gumdrops! Scholars create a model of a lithium atom, complete with protons, neutrons, and electrons. It's just that these models are made with gumdrops and toothpicks.
Teach Engineering
Drawing Magnetic Fields
Class members use a compass and several points to map out the magnetic field of a magnet. Pairs trace the magnetic field lines produced by a permanent magnet by positioning the compass in numerous spots around the magnet to view the...
Teach Engineering
Building an Electromagnet
Your pupils can build their own electromagnet — awesome! The culminating activity in an eight-part series challenges groups to design and build their own electromagnet. The goal of the activity is to build a magnet capable of picking up...
