Computers store drawings, photographs, and other pictures using only numbers. Through this activity, learners decode numbers to create pictures using the same process that computers use.

In this activity (on page 2) about fingerprint analysis, learners use graphite from a pencil and scotch tape to capture their fingerprints.

Data in computers is stored and transmitted as a series of zeros and ones. Learners explore how to represent numbers using just these two symbols, through a binary system of cards.

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

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

Extract your DNA from your very own cells! First, learners swish salt water in their mouth to collect cheek cells and spit the water into a glass.

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

Learners work in groups to build model cars from paper parts. First, each learner builds cars individually and the group times themselves.

Computers are often used to put lists into some sort of order—for example, names into alphabetical order, appointments or e-mail by date, or items in numerical order.

In this activity (page 2 of PDF), learners play with a lens and a piece of paper to focus an image on the paper. Learners look at different things, and see how the lenses affect the image.

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.

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 computer science activity about finite-state automaton (on page 45 of the PDF), learners use a map and choose various pathways to find Treasure Island.

Learners design different shaped bandages for different purposes. First, they draw their designs on paper.

Learners design, build, and test models of "dragon boats" made from up to three milk cartons.

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.

Learners explore the Bernoulli effect by building an airfoil (airplane wing) and making it fly.
