Learners work as a group to create a map of their community. They use pasta to represent people, and glue the pasta on their maps to show areas of large population.

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

In this activity, learners extract DNA from a strawberry and discover that DNA is in the food they eat.

This lesson introduces learners to the world of nematodes (roundworms).

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 construct an air cannon as a model for the human ear.

In this activity, learners sublimate dry ice and then taste the carbon dioxide gas.

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 health activity (page 7 of the PDF), learners will discover the importance of handwashing as a factor in reducing the spread of pathogens.

This is an activity (located on page 3 of PDF under Gecko Feet Activity) about modeling a nanoscale phenomenon (gravity-defying gecko feet) with macroscale objects (shoes).

In this activity, learners make a Benham Top to explore visual illusions and optics.

Learners investigate an iron-fortified cereal by stirring it with a strong magnet. They discover that metallic iron is present in some cereals.

In this activity (page 5 of the PDF), learners will create a food web and explore food sources for different organisms. They will identify relationships between organisms in an ecosystem.

In this activity, learners use a compact disc to make a spectrometer, an instrument used to measure properties of light.

In this activity, learners build a bird feeder or feeders to attract birds for observation.

In this biology/ecology activity, learners construct a terrarium out of a tennis ball container. This terrarium is unique because it never has to be watered.

In this demonstration, learners compare and contrast regular water ice to dry ice (frozen carbon dioxide). Both samples are placed in a solution of acid-base indicator.

Learners place cut flowers in colored water and observe how the flowers change. The flowers absorb the water through the stem and leaves.

This fun hands-on astronomy activity uses a variety of simple props to help learners understand why they see what they see in a telescope.
