This activity explores the main algorithms that are used as the basis for searching on computers, using different variations on the game of battleships.

This activity introduces the idea that computer scientists measure information by how "surprising" a message is.

In this online interactive simulation, learners will add different salts to water and then watch the salts dissolve and achieve a dynamic equilibrium with solid precipitate.

In this activity about computer programming, learners follow instructions in a variety of ways in order to successfully draw figures.

In this activity, learners build bridges using paper and explore how much weight each bridge design can support.

In this activity, learners build bridges and cantilevers in a series of "building out" challenges with straws and pins.

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, learners make bridges using an oil-based modeling clay (plasticene). The instructions include discussion questions for both before and after bridge building.

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 fun hands-on activity, learners create a safety device to protect an egg "passenger" in a toy car crash. Learners experiment with different solutions to this very problem.

In this activity, learners investigate the relative growth of lengths, areas, and volumes as cylinders are scaled up.

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