Alloy Advantage
Mix it up by using an intriguing resource that teaches young metallurgists that alloys are a metal mixture. They learn about the advantages of using alloys over pure metals and investigate titanium alloys as an example to finish the...
Teach Engineering
Solenoids
Metal slinkies, coils of wire, magnetic fields, and MRIs. To determine the safety hazards of MRI machines, class members use the provided formula to calculate the magnetic field along the axis of the solenoid.

TECH:Robotic Hazardous Materials Squad (Manu)
Using a remote-controlled robot, junior engineers simulate a hazardous materials removal exercise. This activity will introduce students to the following careers: robotics technician, hazardous materials specialist, environmental...
Teach Engineering
Magnetic Materials
The design challenge: develop a method to separate steel from aluminum. The first lesson plan in an eight-part series introduces the class to the grand challenge of ciming up with a method to streamline a sorting process at a recycling...
Perkins School for the Blind
Identifying and Using Tools
How can you teach a person about technology and engineering if he has never been exposed to the tools and devices used to create and construct? Learners with visual impairments examine a number of common tools, such as hammers, wrenches,...
National Sailing Hall of Fame
Introduction to Sailboats
The left part of the boat is called what? An informative lesson and accompanying slideshow presentation introduce middle schoolers to the terminology and parts associated with a sailboat.
Curated OER
Finding the Way
Students identify and research navigational tools used in deep sea explorations. They are introduced to a compass, the Global Positioning System and sonar technology and then describe their uses in underwater exploration.

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...
Intel
Prototyping
I need something to test. The three sessions in this lesson have individuals build and test a prototype of their design. The first two sessions are devoted to prepping for the prototype by drawing up specifications and materials. 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 tests to...
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 the...
Teach Engineering
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...
Teach Engineering
Strength of Materials
Pupils examine a stress-strain diagram that compares the advantages and disadvantages of the two common bridge building materials, concrete and steel. The also consider the factors that influence the materials builders choose for their...

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...
