In this activity about light and perception, learners create and observe moire patterns.

As learners play this challenging strategy game, they build understanding of area and perimeter. On each turn, a player draws a line between two dots next to each other on the grid.

In this activity, learners conduct an experiment to find out if steel wool will weigh more or less when it is burned. Learners will explore the effects of oxidation and rusting on the steel wool.

In this activity on page 1 of the PDF, learners compare the relative sizes of biological objects (like DNA and bacteria) that can't be seen by the naked eye.

Learners create an Incan counting device called a quipu (pronounced kee-poo).

This strategy game has simple rules but can be a challenge. Players start with an empty hexagonal grid. On each turn, a player initials one empty hexagon on the grid.

This is an activity/demo in which learners are exposed to the difference bewteen hydrophobic surfaces (water repelling) and hydrophilic surfaces (water loving).

In this physics related activity which requires adult supervision, learners make their own powerful water rocket and, with it, explore Newton's Third Law of Motion.

In this activity, learners use geometry to predict the shape of carbon. Learners twist and attach chenille stem pieces that represent bonds between different carbon atoms.

Learners test two jars containing hot water, one covered with plastic and one open, for changes in temperature.

In this activity, learners will explore how maps can provide information about a place and help us find our way from one location to another.

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.

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

This activity is designed to let learners measure their reaction time or response time to something they see.

Learners shine the light of a laser pointer through sheets of fabric that all have a different number of threads per inch.

In this activity (3rd on the page), learners conduct a series of tests to find out which of their eyes is more dominant.

This activity is a whole-group kinesthetic demonstration that shows learners what it means to be in a "risk group" for developing heart disease based on family history and genetics.

In this activity (4th on the page), learners conduct a series of tests to find out which of their ears is more dominant.

In this activity on page 13 of the PDF, learners use a laser pointer (with known wavelength of light) to measure the thickness of a human hair.

This activity was designed for blind learners, but all types of learners can utilize it to investigate volume, mass, and density.
