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.

This activity (page 2) draws upon a familiar, computer-based concept related to visual resolution: pixilation.

In this activity, learners will explore coding by arranging words and phrases to create an order of operations in this low tech version of computer programming.

This activity requires a Pico Cricket (tiny computer).

In this activity, learners make their own encrypted code to pass along secret messages using a printable cipher wheel.

In this activity, learners examine nanoscale structures of common things.

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

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, learners use cooperation and logical thinking to find solutions to network problems on the playground.

In this activity, learners make their own binary code bracelets by translating their initials into 0s and 1s represented by beads of 2 different colors.

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

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 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

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

In this activity, learners explore electronics and motion by making a Scribbling Machine, a motorized contraption that moves in unusual ways and leaves a mark to trace its path.

In this activity, learners use UV light to transfer a pattern onto a plastic board. The pattern is transferred by placing a mask (a transparency sheet with the pattern) on a plastic board.

In this activity (page 12), learners apply the concepts of pixilation and pointillism to the world of biomedical science.

This is a virtual representation of a sound mixer containing pre-looped sounds of animal, insect, and environmental noises.

This is a virtual representation of a sound mixer containing pre-looped sounds of animal, insect, and environmental noises.

In this web-based activity, learners try to figure out who in an online chat room has their matching puzzle piece.
