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.

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 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).

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.

Make two firefly lanterns, then program them to blink to one another and change 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

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

In this math lesson, learners use slices of bread and geoboards to explore several ways to divide a rectangle in half. Learners also identify equivalent fractions that represent one-half.

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

Learners use scientific processes to solve a crime. As they get clues, learners must create a hypothesis then adjust that hypothesis as more information is revealed.

Put on a pair of gloves and be the conductor of your invisible orchestra!

Use a Pico Cricket (micro-controller) to animate your art! You can program a Pico Cricket to make your art spin, light up, or make music.

In this activity, you take regular dominoes, and turn them into conductive switches that can turn on a LEGO RCX block or Pico Cricket (micro controller). LEGO RCX block or Pico Cricket is required.

Through this nutrition activity (page 5 of the PDF), learners will understand—and probably be surprised by—how big serving sizes of various foods should be.

This activity lets you program your 'robot' (a willing friend) to pick up and dispose of some 'toxic waste' using as few commands as possible.

Play-Doh is conductive! Use the semiconductive qualities of Play-Doh to make your own squeezable instrument. Pico Cricket is required.

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