In this activity, learners discover why some nanoscale science and technology is done in the controlled environment of a clean room, what clean rooms are like, and how scientists help keep the clean r

In this activity, learners create a traditional Mexican noisemaker (a matraca) using cardboard, craft sticks, and a wooden dowel.

This activity (on page 2) explores how sensing is part of robotics. Learners try tying their shoes with different constraints.

In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.

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

Find out what it would be like to have ears shaped differently from your own! Design and make different animal ears then try them out.

In this invention challenge activity, learners see how many objects they can grab with a homemade "bionic" arm.

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

In this activity (posted on March 27, 2011), learners follow the steps to construct a mini zoetrope, a device that produces an illusion of action from a rapid succession of static pictures.

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

This activity requires a Pico Cricket (tiny computer). Learners work on designing and building a sound sensor out of household materials, like plastic wrap and cardboard.

In this delicious activity, learners get to make, taste-test and compare their own "brands" of homemade strawberry ice cream.

In this activity, learners explore the concept of how engineering has made possible the development of--and ongoing improvements to--adaptive devices that serve to help individuals with a wide range o

In this design challenge activity, learners build a four-stringed instrument that can play a tune.

Have you ever heard of a camera without a lens? In this activity, learners create a pinhole camera out of simple materials. They'll see the world in a whole new way: upside down and backwards!

Make a copy of the first stethoscope with only a cardboard tube! René Laennec invented the first stethoscope in 1819 using an actual paper tube!

Learners write a message in Braille using beans to form the patterns of dots. Learners glue beans in place, and then challenge another learner to read the message.

From this How To slide show, you create an Audio Tape Bow that can play distorted audio sounds by running it across a tape head.

In this design challenge activity, learners add headphones to a previously built instrument (see "Build a Band" activity) to make it easier to hear.

In this activity, learners explore how polarizing sunglasses can help diminish road glare.
