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.

This activity shows learners how computers use numbers to represent pictures. A grid is used to represent the pixels (short for picture elements) of a computer screen.

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

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.

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

In this activity, learners cut out 5 paper cards and label them with 1, 2, 4, 8, or 16 dot(s) to explore binary digits.

In this activity, learners find the answer to the question, "if you have a pile of 8 cards, and you remove half, then half again, how many times can you do this until you get to just one card?" This w

In this puzzle, learners investigate the decisions involved in linking a network between houses in a muddy city.

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.

This activity about cryptographic techniques illustrates a situation where information is shared, and yet none of it is revealed.
