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

In this activity, learners conduct a simulation exercise related to public key encryption and try to intercept a message sent between two learners.

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.

This activity about cryptographic techniques illustrates how to accomplish a simple, but nevertheless seemingly impossible task—making a fair, random choice by flipping a coin between two people who d

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.

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

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.

In this math lesson, learners practice estimation and measurement skills as they move from station to station calculating length, volume, weight, and area.

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

In this activity, learners conduct scientific research on multitasking. Learners determine if multitasking with media while doing homework affects their ability to successfully complete the homework.

In this activity, learners create their own weather forecast map.

In this math activity (Page 17 of the Play Ball! PDF), learners play a game of "baseball" and analyze the results of the game.

In this math lesson, learners apply the concepts of ratios and percentages to the distribution of letters contained in a box of Alphabits® cereal.

In this data activity, learners analyze data from coral reef snapshots taken by scientists at the Virginia Institute of Marine Science.

In this activity, learners will use Google Sky to observe features of the night sky and share their observations.

In this activity, learners calculate the number of milliliters of water a nearby tree transpires per day.

In this math lesson, learners determine and compare the rate of descent of various learner-constructed parachutes. Learners construct parachutes that will have maximum hang times.
