Earthquakes Living Lab: Locating Earthquakes
There are patterns in nearly everything — even earthquakes. Pairs research current earthquakes to see if there are any patterns. They determine the mean, median, and mode of the earthquake data, along with the maximum and minimum. Using...

Keep-a-Cube
Waxed paper, newspaper, or aluminum foil? Keeping an ice cube from melting may require one or more of these materials. Learners design a box that will provide insulation so an ice cube stays intact for at least 90 minutes.

Build a Big Wheel
Pasta is great for cooking—and for making Ferris wheels. Aspiring engineers use an assortment of pasta types to create a functioning Ferris wheel. They keep track of the design process to refine their designs, if necessary. Let's hope no...
Beauty and Joy of Computing
Algorithms
Introduces the class to the idea of searching a list by building a script. Learners modify a guessing game script that will find a number in a list.
Teach Engineering
Magical Motion
Make solutions to projectile motion problems magically appear using equations. Pupils watch a clip from a Harry Potter movie and find the length of time it takes for a remembrall to fall into Harry's hands. They use a projectile motion...
Teach Engineering
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...

Hands-On Engineering Challenges to Bolster Your Electricity, Sound, and Force Units
Need some activities to go along with your unit? A collection of hands-on activities from PBS offers opportunities to add to your electricity, sound, and force units. The electricity activities revolve around building a pinball-type...
Teach Engineering
Show Me the Genes
Give your class a chance to show what they know. In the last installment of a seven-part series, pupils summarize and review what they have learned in the series. They present their solutions for creating a biosensor to detect cancer...

Protecting Our City with Levees
Teams use the design process to design, build, and test a model levee to protect the town from a wall of water. A handout provides a price list for the materials learners can use to build their levee within a budget.
Teach Engineering
Measuring Viscosity
Groups use a marble to determine the viscosity of household fluids. The procedure calls for pupils to measure the amount of time it takes a marble to fall a specified distance in the fluids. Using unit conversions and algebra, the teams...
Teach Engineering
Chromatography Lab
Groups use alcohol and chromatography paper to separate the color components of black ink. The purpose of the activity is to allow the class to become aware that mixtures exist in hidden places.
Teach Engineering
A Simple Solution for the Circus
Class members are challenged to design a device that will move a circus elephant into a train car. Groups brainstorm ideas that use simple machines to load the elephant. They then choose one of their ideas, sketch a plan, and present it...
Teach Engineering
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, allowing the...
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
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...
