This is an activity (located on page 3 of the PDF under Water Clean-up Activity) about the use of reduction agents to decontaminate ground water.

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 outdoor activity and game, learners explore how animals adapt for survival through coloration, markings and camouflage.

In this activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes.

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 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, learners construct a robot-like hand to demonstrate how data is collected when using robotic technology.

This activity guide includes instructions on how to build a "Shake Table" by mounting an eccentric mass (off center) on the shaft of a small dc motor.

In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.

In this design challenge activity, learners build a tower that can support a tennis ball at least 18 inches off the ground while withstanding the wind from a fan.

In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.

In this activity (page 1 of the PDF under SciGirls Activity: Dinosaurs), learners will model how paleontologists estimate the age of fossil discoveries by extracting “fossil” playing cards from newspa

In this activity, learners investigate passive solar building design with a focus solely on heating.

In this outdoor activity, learners design devices that will catch prey or gather plants.

This activity (on pages 38-43) has learners simulate the way scientists track and map the movement of otters in the wild using radio trackers.

In this physics activity (page 10 of the PDF), learners will explore how energy from moving water can be used.

Using simple materials, learners will construct the end effector (grasping device) of a robotic arm and use the device to capture and pick up an object.

In this experiment, learners design and build a model room in a shoebox and furnish it with tiny furniture.

Learners will explore the scientific mystery behind a disappearing group of trees by examining data and attempting to explain the decline.
