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

Visitors observe a graduated cylinder with a golf ball floating about halfway in liquid. The bottom half of the cylinder contains a concentrated solution of salt.

In this activity (on pages 10-17), learners discover how scientists study biodiversity and the health of the environment based on inspection of small areas—a process known as sampling.

In this activity related to microbes, learners make slides of cells from an onion skin and Elodea (American or Canadian waterweed) to observe under a microscope.

In this sensory activity, young learners explore chemical reactions by making their own play dough from home.

In this activity, learners explore the real science behind an egg drop "magic trick." Learners will wow their families by harnessing gravity, friction and motion to make 3 eggs fall off of their pedes

After an interest-generating discussion about "dirt" and microbes, learners select and collect soil samples from a variety of locations (schoolyard, home, etc.).

In this activity, learners explore liquid crystals, light and temperature. Using a postcard made of temperature-sensitive liquid crystal material, learners monitor temperature changes.

In this activity, learners will build an instrument from common household items. Explore sound through vibrations created by your vocal chords and captured by an instrument.

Using a vertical wind tube and using simple materials, individuals and groups attempt to design a "satellite" that floats for at least 5 seconds.

In this activity (on page 4), learners create a submarine using a plastic sandwich bag. This is a fun way to learn about buoyancy and how captured gas can cause objects to float.

In this activity, learners create a tornado in a bottle to observe a spiraling, funnel-shaped vortex. A simple connector device allows water to drain from a 2-liter bottle into a second bottle.

In this hands-on experiment, kids use chemistry to explore whether acids or bases are better at restoring a penny’s shine.

In this health activity (page 6 of the PDF), learners examine ingredient labels of packaged food products to find out what sugar ingredients they contain.

Learners investigate the properties of the liquids in two bottles. One contains layers of oil and water, and one contains oil, water, and soap.

In this activity on page 6 of the PDF, learners dissolve Epsom salt in water and discover that the resulting solution can be used to create a work of art.

In this fun and, at times, hilarious force and motion activity, learners will use household objects to build a crazy contraption and see how far they can get a tennis ball to move.

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 fun hands-on activity, learners use simple materials to investigate evaporation. How can the evaporation of water on a hot day be used to cool an object? Find out the experimental way!

In this physics activity, learners will build their own parachutes out of tissue paper. They will explore the effects of weight, height, and design on the parachutes' speed and stability.
