Pushing it Off a Cliff
Focus on the conservation of energy, specifically looking at gravitational potential energy and kinetic energy, with a lecture that involves having friends throw light objects at each other to determine which has more kinetic energy and...
Teach Engineering
Quantum Dots and Colors
Introduce teams to quantum dot solutions with an activity that has them expose solutions to a blacklight, observe the colors, and take measurements. Groups graph the data and analyze the dependence between particle size and color...
Teach Engineering
Nanotechnology as a Whole
It's a small (nanotechnology) world after all! The first segment of a six-part series gives an overview of nanotechnology, its principles and applications, and shares some of the engineering applications of nanotechnology. A presentation...

Get the Word Out at McDonald's!
To get the word out that the Great Pacific garbage patch (GPGP) contains millions of pounds of non-biodegrading plastics, individuals research the GPGP and write an article for a newsletter. Researchers present their facts in a way that...
Teach Engineering
What's Wrong with the Coordinates at the North Pole?
Here is an activity that merges technology with life skills as individuals use Google Earth to explore the differences between coordinate systems and map projections. The self-guided activity is the fourth segment in a nine-part unit....
Teach Engineering
What is GIS?
Is GIS the real manifestation of Harry Potter's Marauders Map? Introduce your class to the history of geographic information systems (GIS), the technology that allows for easy use of spatial information, with a resource that teaches...
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 data...
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...
Teach Engineering
Load It Up!
See how a marshmallow can hold up a bridge load. Teams take a closer look at the design of bridge piers. They determine the types of loads that might affect a bridge, and, using that information, they calculate the needed cross-sectional...
Teach Engineering
Designing Bridges
Introduces your class to the types of loads experienced by a bridge. Groups calculate the ultimate load combinations to determine the maximum load requirement. Using this information, builders then determine the amount of material they...
Teach Engineering
Straw Bridges
Pairs work as engineering teams to design and build model bridges from drinking straws and tape. In this third segment in a series of 10, teams compete in an attempt to build the strongest bridge. To help with the design, the groups...
Teach Engineering
Bridging the Gaps
The London Bridge should not have fallen down. And here's why. After a brief history of bridges and the three main types, class members are introduce to the concepts of tension and compression, the two main forces acting upon bridges.
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.
Teach Engineering
Magnetic Fluids
Teams work as material engineers to create ferrofluids, whose shape is influenced by magnetic fields. The activity, which is the fourth in the six-part series, has the teams create magnetic ink and use it to write, testing it with a...
Teach Engineering
Projections and Coordinates: Turning a 3D Earth into Flatlands
Introduce your class to map projections and coordinates, the basics for the work done in a GIS, with an activity that uses Google Earth to challenge learners to think about the earth's shape.
Teach Engineering
The Great Pacific Garbage Patch
The Great Pacific Garbage Patch is one of several garbage patches around the world where garbage accumulates naturally. As part of a GIS unit that combines oceanography, environmental science, and life science, class members investigate...
Teach Engineering
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
Identifying Possible Underground Cavern Locations
Teams continue with the Asteroid Impact challenge and determine possible locations to construct their underground shelters. Participants cut scale area models of their shelters from paper and place them on the map to find locations to...
Teach Engineering
Using Map Scales to Figure Distances and Areas
The asteroid is getting closer and the question is whether the state of Alabraska is large enough for the shelter calculated in the previous activity. Teams determine the scale of their project and then use the scale on the map to...
Teach Engineering
Automatic Floor Cleaner Computer Program Challenge
Have your class use the engineering design process to program a vacuum robot. Using computer engineering concepts, teams program an automatic floor cleaner to traverse designated patterns.
Teach Engineering
Super Slinger Engineering Challenge
How well can you launch a ping-pong ball? Small groups design launchers that can launch a ping-pong ball 20 feet into a target. The teams follow the engineering design process as they develop a solution that meets the design...
