Smart Domino Tricks
Source Institutions
In this activity, you take regular dominoes, and turn them into conductive switches that can turn on a LEGO RCX block or Pico Cricket (micro controller). LEGO RCX block or Pico Cricket is required.

Shake it up with Seismographs!
Source Institutions
In this activity, learners explore the engineering behind seismographs and how technology has improved accurate recording of earthquakes.

Build a Battery
Source Institutions
Learners make a simple battery out of "sandwiches" of aluminum foil, pennies, and a salt water-soaked paper towel.

What Trickles Down?
Source Institutions
Learners design their own experiment to explore the permeability of different materials such as soil, sand, gravel, and marbles.

Design a Lunar Rover!
Source Institutions
In this team design challenge (page 2-10 of PDF), learners design and build a model of a Lunar Transport Rover that will carry equipment and people on the surface of the Moon.

Magnetic Marble Run
Source Institutions
Learners explore magnetism and motion as they build a simple marble run. Learners test different arrangements of plastic and cardboard tubes, bottles, and cups on a magnetic board.

First Impressions
Source Institutions
Learners experiment with a commercial photo-sensitive paper (Sunprint® or NaturePrint® paper). They place opaque and clear objects on the paper and expose it to bright light, observing the results.

Ripening of Fruits and Vegetables
Source Institutions
In this activity, learners test the rate of ripening fruit and vegetables and use a chemical to inhibit the ripening process.

Folding Matters
Source Institutions
In this activity, learners explore how the process of folding has impacts on engineering and is evident in nature.

Musical Sculpting Machine: Squeeze Play-Doh to Make Music
Source Institutions
Play-Doh is conductive! Use the semiconductive qualities of Play-Doh to make your own squeezable instrument. Pico Cricket is required.

Catapult
Source Institutions
Build a catapult that transforms the potential energy of a twisted rubber band into kinetic energy. Experiment with design variations so that you can hit a target with a projectile.

Proportionality: The X-Plane Generation
Source Institutions
In this activity, learners build a 1:140 "scale model" of NASA's X-33 Reusable Launch Vehicle (RLV) Technology Demonstrator, and investigate how the model dimensions compare to the real vehicle.

Twirling in the Breeze
Source Institutions
In this engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.

Clean Water: Is It Drinkable?
Source Institutions
In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.

Big Wave
Source Institutions
This is an activity about waves. Using marbles, paper clips and rubber bands, learners explore how waves behave.

Crank It Up
Source Institutions
In this engineering activity, learners explore simple machines and then build cardboard automata using cams.
Pesticide Watch Card
Source Institutions
After learning that some of the chemicals we add to food crops may have harmful consequences on our health and the health of the environment, learners will create a pocket-sized card with their favori

DNA Detective
Source Institutions
This activity is about collecting and analyzing DNA as part of a criminal investigation.

Design Your Own Rube Goldberg Machine
Source Institutions
Engineer and cartoonist Rube Goldberg is famous for his crazy machines that accomplish everyday tasks in overly complicated ways.

Casting and Molding
Source Institutions
This activity was designed for blind learners, but all types of learners can explore the process used to cast and mold molten metal, glass, and plastics.
