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

In this technology activity, learners explore digital imaging and pixels. Learners "transmit" an image to a partner by creating an image on grid paper.

In this activity (on page 2), one person "programs" the other like a robot to move through a space, trying to get them to avoid obstacles and reach a goal.

In this activity about human interface design issues, learners help the Oompa-Loompas of a great chocolate factory solve different problems.

Learners create an Incan counting device called a quipu (pronounced kee-poo).

Learners make their own simple slide rules out of paper and learn how they work.

In this activity about encryption, learners cut out a secret decoder badge from a handout and use it to encode messages to each other.

When a lot of people share one network (such as cars using roads, or messages getting through the Internet), there is the possibility that competing processes will create a “deadlock," or an interrupt

MarsBound! is an engineering simulation activity in which learners use realistic techniques to plan a mission to Mars.

Even fast computers are limited to how quickly they can solve problems. One way to speed things up is to use several computers at once.
