Learners write a message in Braille using beans to form the patterns of dots. Learners glue beans in place, and then challenge another learner to read the message.

In this activity, learners explore the concepts of density and basic chemical reactions as they create a homemade lava lamp effect using water, oil, food coloring, and Alka-Seltzer tablets.

In this activity related to magnetism and electricity, learners observe as two parallel, current-carrying wires exert forces on each other.

In this introductory activity, learners discover that sugar and food coloring dissolve in water but neither dissolves in oil.

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

Learners build a small rocket using a matchstick and a piece of aluminum foil. A second, lit match launches the match rocket. This activity involves fire; adult supervision required.

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 physics activity (page 14 of the PDF), learners gain a better understanding of how friction and mass affect objects by comparing the rotational inertia of raw and hard-boiled eggs.

This activity is about how you form mental images of your body's position in space, independent of vision. Can you take a sip of water from a cup with your eyes closed?

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 guided discussion activity, learners watch a video about Central Africa's Lower Congo River, one of the most biologically diverse rivers in the world.

This activity uses turmeric, a common spice in curry, as an indicator for acidity and basicity. Turmeric is yellow in acid and neutral substances, but turns bright red with bases.

This fun astronomy activity allows learners to experience finding stars in the night sky that will eventually go supernova. This activity is perfect for a star party outdoors.

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 (page 3 of the PDF), learners will observe a physical change.

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.

In this activity, learners create a hearing based memory game that they can share with friends.

In this activity, learners will work together to create a program to navigate a Remotely Operated Vehicle (ROV) through an obstacle course.
