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 investigate just how small a billionth of a meter is by attempting to cut a paper ruler down to a nanometer-sized sliver.

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.

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

In this activity, learners play a card game that explores the relative sizes of various objects. Learners compete to organize their hand of cards into lists of objects from largest to smallest.

In this activity, learners mark their height on a height chart and discover how tall they are in nanometers.

Learners make their own simple slide rules out of paper and learn how they work.

In this activity, learners play a card game that explores different size scales--macro, micro and nano.

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

This simple activity uses paper and scissors to convey two key concepts to learners: the nanoscale is very small and working on the nanoscale requires special tools.

In this game, learners try to find nano-related objects on a game board. Learners investigate the different ways nano is in the world around us.

This game introduces learners to the scale of the greenhouse gas problem, plus technologies that already exist to dramatically reduce our carbon emissions and prevent climate change.
