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

Build a catapult that transforms the potential energy of a twisted rubber band into kinetic energy. Experiment with design variations so that you can hit a target with a projectile.

In this physics demonstration, learners are challenged to break a raw egg just by squeezing it. Learners will be shocked by their inability to complete the deceivingly simple challenge.

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

Learners create a small explosion by collecting hydrogen and oxygen gas together and squeezing them into a flame.

In this hands-on activity, learners use heat to shrink samples of polystyrene plastic (#6 recycle code). Learners compare the size and shape of the plastic pieces before and after shrinking.

Learners compare the properties and solubilities of Styrofoam (TM), ecofoam packing peanuts, and popcorn. First, the solubility of each substance is tested in water.

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

In this three-part activity, learners use paper to explore Bernoulli's Principle — fast-moving air has lower pressure than non-moving air.

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

In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.

In this activity, learners electrically plate zinc onto brass objects.

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.
