Clipper Creations
Source Institutions
In this activity, learners create a working model of a nail clipper. This activity helps learners learn the basic principles of simple machines, engineering design and model building.

Jam Jar Jet
Source Institutions
In this activity, learners create a "Jam Jar Jet" based on Francois Reynst's discovery of a pulsejet engine, which uses one opening for both air intake and exhaust.

Heavy Lifting: Design Squad
Source Institutions
In this engineering challenge, learners design and build a crane out of cardboard to see how heavy a load it can lift.

Infrared Investigations
Source Institutions
In this activity, learners explore how infrared technology is used by engineers to create equipment and systems for a variety of industries.

Tinkering with Tops
Source Institutions
In this activity, learners explore the history, design and motion of spinning tops. Learners work in teams of "engineers" to design and build their own tops out of everyday items.

Statue Display Tower
Source Institutions
In this activity, learners design, build, test and redesign a display tower that will meet a specific set of criteria and constraints.
Happy City
Source Institutions
Make a model city happier with LEDs, circuits, motors, and batteries! Groups can think, discuss, design, and build what would make a community happy. Kids can work as part of a team or on their own.

Linkages
Source Institutions
This design challenge is an open-ended exploration of linkages, a group of parts connected by hinges, and the types of motion they can create.
Stranded
Source Institutions
What's a more compelling problem to solve than being stranded on a deserted island?
