Search Results

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 game, learners experience how computers divide a big problem into many smaller ones and how they use binary "yes"/"no" questions.

In this math activity (Page 12 of the Play Ball! PDF), learners play a game of "soccer" and analyze the results of the game.

In this math activity (Page 14 of the Play Ball! PDF), learners play a game of "basketball" and analyze the results of the game.

In this game, learners build up six stacks of cards in the middle of the table, face up, in order from 1 at the bottom to 20 on the top. The first player to get rid of all his cards is the winner.

In this activity, learners use their understanding of probability to guess which color will be drawn from a bag.

Professor John Endler traveled to Trinidad in the 1970s to study wild guppies. In this activity, learners take part in an online simulation of Endler's work.

These three short activities challenge groups to fit objects through paper and index cards: "Slots" presents the challenge for one learner to figure out which objects fit through a hole cut by another

In this math activity, learners play a game in which every roll can earn you counters, but if you roll the wrong number (6), you have to put everything back.

In this Cyberchase activity, use grid coordinates to share secret pictures with a friend. Color squares of a grid to make a picture (like a smiley face) that you keep hidden from the other person.

In this activity, learners play an evolution card game to see how selective pressures can affect an organism's evolution.

In this math game (Page 14 of the Are You Game? PDF), learners determine the probability of getting an even versus an odd product using the numbers on a regular deck of cards.

In this activity, reuse two-liter bottles to create bowling pins. Learners practice math skills and develop a concept of verifying answers, while bowling and keeping score.

In this activity, learners will explore the physics of liquids and gas by playing with both! Learners of any age use their own breath to move drops of water across a smooth wax paper surface.

In this math lesson, learners play a game to identify the properties of prime, composite, abundant, deficient and perfect numbers.

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

Learners use their opponent's clues and a compass rose to find the hidden treasure on a map. Learners use problem solving and coordinate grid skills as they hunt for treasure.

In this math activity, learners play a number game to explore the relationships between numbers, combinations, and the concept of equivalency.

In this activity (15th activity on the page) about the sense of touch, learners use glue and cardboard to construct a maze they use with their eyes closed.
