Rocks, Rocks, Rocks: Test, Identify Properties and Classify
Time is growing short. Teams work together to identify physical properties of rocks in order to determine the properties that would best suit their cavern shelter design.
Teach Engineering
Ranking the Rocks for Desired Properties
Math rocks! Cavern design teams determine the rankings of rock types based upon desirability points. The points are connected to the properties of the rocks and their usefulness in building a cavern.

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...

Clay Boats
Clay itself sinks, but clay boats float. Why? Young engineers build clay boats to learn about buoyancy. They test the weight the boats can hold using washers and then tweak their designs to make improvements, following the engineering...
Teach Engineering
Windy Tunnel
Lift—it is about the wing's attack. Using a virtual wind tunnel, pupils investigate wing shape and angle of attack. Learners use worksheets to record their observations and to convert verbal relationships into mathematical equations in...

Efficiency of a Water Heating System
Tired of waiting for hot water? Groups of three determine the efficiency of an electric water-heating device. They calculate the amount of energy it takes to heat the water and the theoretical amount of energy required to heat the water....
Teach Engineering
Light vs. Heat Bulbs
Careful, that light bulb is hot! Compare heat and light energy using a simple light bulb. The exercise addresses energy conservation and presents actual calculations to determine the most cost-effective light bulb.
Teach Engineering
Model Heart Valves
Small groups use the knowledge learned about the heart to design and build a prototype of an artificial heart valve. The teams demonstrate the functionality of their valve. They are also responsible for creating a pamphlet that describes...

Visualizing Magnetic Field Lines
Magnetic fields might not be a field of dreams but they are useful. Class members observe the reactions of magnetic fields using a compass, iron filings in a paper container, and iron filings suspended in mineral oil.
Teach Engineering
Breaking the Mold
A little too much strain could cause a lot of stress. Groups conduct a strength test on clay. Using books as weights, pupils measure the compression of clay columns and calculate the associated strain and stress. Teams record their...
Teach Engineering
Searching for Bigfoot and Others Like Him
Individuals create a GIS data layer in Google Earth that displays information about where one might find seven different cryptids. The class members research to find data on cryptid sightings they can include in their data...
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
Applying Statistics to Nano-Circuit Dimensions in Fabrication
Do flexible circuits change dimensions during fabrication? Groups use GeoGebra software to measure the length of pictures of flexible nano-circuits. To determine if the circuits change dimensions, future engineers use Microsoft...

Considering Trade-Offs and Maximizing Efficiency in a Fast Food Restaurant
Make fast food restaurants even faster. Groups consider trade-offs when maximizing efficiency in fast food restaurants. Restructuring schedules and floor plans, as well reassigning job duties, all fall under this directive.
Teach Engineering
Let's Take a Spin: One-Axis Rotation
Investigate the effect of one-axis rotations on geometric figures. Scholars learn to use snap cubes and the right-hand rule to draw figures after rotations about the x-, y-, or z-axes. They try their hands at examples created by the...
Teach Engineering
News Flash!
Extra, extra, read all about it! Scholars research information on endangered species and produce a news report to share their findings with the rest of the class. In groups, they then consider engineering solutions to problems on habitat...
Teach Engineering
Design Inspired by Nature
Let nature guide your engineering designs. By taking apart a flower, pupils learn about reverse engineering. They use the results to brainstorm designs for new products or ideas. This is the seventh installment of a nine-part Life...

Messin' with Mixtures
Do you separate your trail mix before eating it? Then you've been separating mixtures your whole life! Scholars model a contaminated soil sample using trail mix and estimate the percentage of each component. They consider how to clean up...
Curated OER
Tech Integration Project Lesson Accelerator: Project Overview
Prepare middle schoolers for life in the tech world with a lesson on entering, storing, sorting, and creating database collections. They use a database tool, such as excel, to record the contents of their CD collections. They then...
