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.

In this activity, learners explore the concept of how engineering solved the problem of human/computer interface.

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.

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 math lesson, learners use simple addition facts to compute values (in dollars and cents) for their names.

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 (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 can program a compass to draw a circle by itself using a Pico Cricket, some Legos, and lots of tape! Pico Cricket is required.

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

In this math lesson, learners make estimates to analyze the number of apples per acre, and visualize the magnitude of one million.

In this math lesson, learners apply mathematical modeling to solve a real-world storage problem, in which a manufacturing company is given two options for storing oil barrels.

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.

In this math lesson, learners identify and compare unit costs of given items. Learners use computation skills, problem solving and number sense to find the cost of an ounce of cereal.

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

In this pencil and paper activity, learners work in pairs and simulate how astronomical spacecraft and computers create images of objects in space.
