Exploring Structures
Source Institutions
This event guide features three related explorations in which learners investigate the following science concepts: how you design and build a structure helps determine how strong it will be; different

Hoop Glider
Source Institutions
In this activity, learners engineer a flying glider using paper hoops and a drinking straw.

Balloon Car
Source Institutions
In this physics activity, challenge learners to make and race a balloon-powered car. Learners construct the body out of a paper cup, wheels out of wooden spools. and fuel tank out of a balloon.

Geometry and Algebra: The Future Flight Equation
Source Institutions
In this activity, learners discover how NASA engineers develop experimental aircraft.

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.

Reusable Rockets
Source Institutions
This activity (located on page 3 of the PDF under GPS: Garbology Activity) is a full inquiry investigation into design optimization using recycled materials.

Engineer a Dam
Source Institutions
In this activity, learners explore the function and engineering of dams and how dams have many uses and solve many problems in the world.

Hot Air Balloon
Source Institutions
In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.

Hand Spin Helicopter
Source Institutions
In this activity, learners build helicopters and launchers using wooden dowels and scrap paper. Use this activity to explore rotational motion and kinetic and potential energy.

Design a Landing Pod!
Source Institutions
In this team design challenge (page 11-18 of PDF), learners design and build a Landing Pod for a model Lunar Rover (previously built in activity on page 1-10 of PDF).

Balloon Hovercraft
Source Institutions
In this activity (on page 2 of the PDF under GPS: Luge Activity), learners will construct a model hovercraft out of an empty spool and a piece of cardboard.

Bottle Cars
Source Institutions
In this activity, learners explore motion, energy, and electricity by constructing bottle cars that run on motors.
Up, Up and Away with Bottles
Source Institutions
In this activity, learners make water rockets to explore Newton's Third Law of Motion. Learners make the rockets out of plastic bottles and use a bicycle pump to pump them with air.

Achieving Orbit
Source Institutions
In this Engineering Design Challenge activity, learners will use balloons to investigate how a multi-stage rocket, like that used in the Interstellar Boundary Explorer (IBEX) mission, can propel a sat

Construction Technologies: Construct the Strongest Bridge
Source Institutions
Learners work in pairs to create three simple types of bridges, a beam bridge, an arch bridge, and a suspension bridge.

Newton Car
Source Institutions
In this activity, learners work in teams to investigate the relationship between mass, acceleration, and force as described in Newton's second law of motion.

Rubber Band Racer
Source Institutions
In this activity, learners construct speedy vehicles made out of paper plates and powered by twisted rubber bands.

Evolution in Plane Sight
Source Institutions
In this activity, learners model directed evolution by making paper fly. Learners construct and fly paper airplanes.

Paddle Boat
Source Institutions
In this activity, learners build an old-fashioned paddle boat out of simple materials.

Above Water: Buoyancy & Displacement
Source Institutions
In an investigation called "Shape It!" learners craft tiny boats out of clay, set them afloat on water and then add weight loads to them, in order to explore: how objects stay afloat in water; what th
