In this activity, learners play a game similar to Hangman by guessing a secret phrase to understand how computer scientists measure the amount of "information" in a document.

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 activity, learners recreate a method of detecting and correcting errors in computers called 'parity'.

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

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

This game asks you a series of questions about how much time you spend in front of a screen, not being active.

This activity (page 2) draws upon a familiar, computer-based concept related to visual resolution: pixilation.

In this activity, learners examine nanoscale structures of common things.

In this activity, learners will divide into teams or groups of equal size. “How many teams of three can we make?” “We need an equal number of children at each of the four computers.

In this fun and interactive online exhibit, the straight lines of a tile wall appear to curve. The learner moves the rows of tiles and changes the color of the grout to achieve the intriguing effect.

In this online version of the classic paper and pencil game, learners practice looking ahead to anticipate an opponent's move.

In this interactive game, learners compare their music-listening skills with that of a three-month-old baby.

In this online Flash game and spacewalk mission simulation, learners are challenged to repair parts of a space station while balancing their oxygen and fuel use carefully.

This is a virtual representation of a sound mixer containing pre-looped sounds of animal, insect, and environmental noises.

In this number puzzle/trick, learner #1 thinks of a number between 1 and 63. Learner #2 shows learner #1 six cards and asks them whether the cards contain their number.

This is a virtual representation of a sound mixer containing pre-looped sounds of animal, insect, and environmental noises.

In this interactive game, learners will test their memory of animal and insect sounds. Flip over cards, listen to the sound, and try to find the ones that match.

This online game tests reaction time. The learner controls a computer-generated frog, and must press a button as soon as a fly appears on the game's radar screen or can be heard from the speaker.

In this activity on page 4 of the PDF, explore the unique molecular structure and conductive nature of graphene. Learners construct a circuit with a battery and LED bulb.
