In this sports-themed engineering activity, learners create super bouncy balls out of balloons. Learners brainstorm, test their designs, and share results.

In this activity (on pages 4-5), learners make fake snow by adding water to the super-absorbant chemical from diapers, sodium polyacrylate.

In this activity, learners build a 1:140 "scale model" of NASA's X-33 Reusable Launch Vehicle (RLV) Technology Demonstrator, and investigate how the model dimensions compare to the real vehicle.

In this engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.

In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.

This is an activity about waves. Using marbles, paper clips and rubber bands, learners explore how waves behave.

In this engineering activity, learners explore simple machines and then build cardboard automata using cams.

After learning that some of the chemicals we add to food crops may have harmful consequences on our health and the health of the environment, learners will create a pocket-sized card with their favori

In this robotics activity, learners find ways to express emotions and feelings using only body movements, not facial expressions.

In this activity (pages 3-4), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.

In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.

Make your own speaker with a magnet, wire, and paper cup! If you have a radio with a headphone plug and an old pair of headphones, this is a great tinkering activity.

In this activity related to plant biotechnology, learners transform a strain of E. coli using green fluorescent protein from a bioluminescent jellies.

In this design challenge, leaners attempt to build a strong structure out of LEGO® bricks that can withstand a 4-foot drop.

Oboes's unique sound originates from the two small reeds a musician blows into. Make your own double reed instrument out of straw!

In this activity, learners explore the concept of how aerospace engineering has impacted sports, specifically exploring the design of golf balls.

In this activity, learners turn empty 2-liter bottles into a see-through compost container.

In this physical sciences activity, learners explore insulation. Leaners investigate how insulation can be used to slow down the conduction of heat from one side of a wall to the other.

This activity is about collecting and analyzing DNA as part of a criminal investigation.
