This activity explores the main algorithms that are used as the basis for searching on computers, using different variations on the game of battleships.

This activity introduces the idea that computer scientists measure information by how "surprising" a message is.

In this activity, learners use a straight line to learn about circles. Learners measure and record the diameter and circumference of different sized cylindrical objects on a chart.

In this activity, learners help a poor cartographer color in the countries on a map, making sure each country is colored a different color than any of its neighbors.

This activity introduces the idea of "divide and conquer" using a fictitious but serious problem--a pair of dirty socks has accidentally been wrapped in one of the presents that Santa is about to deli

This activity helps students learn how computers "compress" text by identifying repeating patterns of letters, words, and phrases.

In this activity, learners listen to songs and decode hidden messages based on the same principle as a modem. As a final challenge, learners decode the binary messages in a music video.

In this activity, learners will first learn the basics of galaxy classification and grouping.

This magic trick is based on how computers detect and correct data errors.

In this activity, learners graph 48 hourly air temperatures from a local weather observation site and observe the diurnal temperature variations.

In this activity, learners build a stuffed-animal zip line. Learners hold a cord against a wall, hook a cute stuffed animal onto it, let the animal slide down, and records its travel time.

In this activity, learners discover how their heart rate changes in different situations.

This activity lets learners participate in the process of reconstructing a phylogenetic tree and introduces them to several core bioinformatics concepts, particularly in relation to evolution.

In this health and fitness activity, learners focus on the importance of daily physical activity, specifically walking.

In this activity (on page 2 of PDF under GPS: Sea Turtles Activity), learners will model how a sea turtle population changes over time, from eggs to adults, using puffed rice.
