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 (on pages 41-47 of PDF), learners explore tesselating geometric patterns (repeated shapes, similar to the art of M.C. Escher).

Millions of organisms can live in and around a body of water.

In this tabletop activity (on pages 32-40), learners make Möbius strips -- 3D surfaces with only one side.

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 fun and simple hands-on astronomy activity lets learners build a scale model of the universe with little more than adding machine tape.

In this math activity, based on the research of famed astronomer Frank Drake, learners calculate the possibilities of finding intelligent life elsewhere in the universe besides Earth.

In this activity about tangrams, learners print and cut out their own tangram shapes and solve puzzles by fitting these geometric pieces together in a variety of ways.

Use geometry, a ruler, and a steady hand to create these amazing unfurling paper folds!

In this craft activity, learners create a string of cut-out moons and stars.

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.

In this activity (on pages 49-54 of PDF), learners play with tangrams, a set of triangles, squares and a parallelogram that can combine into a larger square as well as all sorts of other shapes.

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.

Learners will do an experiment to determine which type of paper is strongest while focusing on variables and collecting data.

This is an activity about reaction times. Just how quickly must an NHL goalie respond to save a shot, and how does your reaction time compare?

This fun hands-on astronomy activity lets learners explore models of the Milky Way and other galaxies to get a sense of relative distances to other galaxies.

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.

In this activity, learners use a string and pair of scissors to find pi in the world all around them. Take the circumference of a round object with string and cut the string to that length.
