This fun activity uses simple materials such as milk cartons and mirrors to introduce the ideas of optics and visual perception.

This activity models the necessary balance of creating power and cleaning up its associated waste. Learners participate in a game where they attempt to move forward toward a goal.

This activity was designed for blind learners, but all types of learners can explore the process of extrusion used to produce pipes and wires in industry.

In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.

In this quick activity (page 1 of the PDF under SciGirls Activity: Tug O' War), learners will test how many pennies a flat paper index card bridging the gap between two stacks of books is able to supp

In this activity, learners compare water pressure at different depths. Learners discover that water pressure increases with depth.

In this activity, educators can demonstrate how the nanoscale arrangement of atoms dramatically impacts a material’s macroscale behavior.

In this physical activity, two lines of learners link hands and arms to model a beam subject to various loading schemes.

In this activity related to computer programming, learners give directions to a "robot" (either an adult or another learner) and find out which instructions the robot is able to follow, and how their

In this physics activity, learners build their own rockets out of film canisters and construction paper.

In this activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.

Learners observe and discuss a simple model of a wet scrubber, a device for cleaning industrial air pollution.

In this activity on page 9 of the PDF, learners make their own paint using chalk as a pigment and glue and water as binders. This activity introduces learners to special mixtures called suspensions.

In this activity about electricity, learners explore what happens when you blow a fuse.

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 construct a rocket powered by the pressure generated from an effervescing antacid tablet reacting with water, and build a launch pad for their rocket.

Use this model to demonstrate the goal of NASA's Kepler Mission: to find extrasolar planets through the transit method.

In this activity about problem-solving, learners build a house for the Three Little Pigs using twenty straws and two index cards.

In this activity, learners discover the difficulty of ocean exploration by human beings as they investigate water pressure.

This activity investigates how bark beetles can threaten forests by having learners estimate the number of infected trees from a photo.
