Students design and create their own air-powered rockets, in this hands-on activity.

Learners observe projectile motion by launching wooden balls off of a table top. They set up a rubber-band launcher so that each ball experiences a consistent amount of force.

In this activity, learners discover that some things only stand up while they are spinning.

This lab activity has learners create a pendulum with a one-second period.

In this hands-on engineering project, kids use two simple machines, levers and inclined planes, to construct their own pinball machines.

In this team design challenge (page 19-24 of PDF), learners "land" a model Lunar Rover in a model Landing Pod (both previously built in activities #3 and #4 in PDF).

In this activity (located on pages 23-24 of the PDF), learners are introduced to structural engineering and encouraged to practice goal-oriented building.

In this activity, learners will explore pendulum motion through scientific trials by using household items with different length strings.

The goal of this activity is to design, build and test a house or toy for an animal.

Engineer and cartoonist Rube Goldberg is famous for his crazy machines that accomplish everyday tasks in overly complicated ways.

Learn about friction and kinetic energy with this cool spinning toy.

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.

In this activity, learners experiment and collect data during a simulation of the fluid shifts experienced by astronauts' bodies in microgravity.

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).

In this activity about friction and gravity (page seven of the pdf), learners use toy racing cars to explore how the two forces affect the motion of objects.

In this engineering activity (page 5 of PDF), young learners investigate how materials and design contribute to the strength of a structure, particularly walls.

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

In this activity, learners use simple materials and basic tools to construct a special toy to explore pendulums. As the head of the toy bobs one way, the eyeballs bob the other way.

In this activity, learners test how cornstarch and glitter in water move when disturbed. Learners compare their observations with videos of Jupiter's and Earth's storm movements.

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