In this activity, early learners create paintings by making music and rhythm. Learners place paper in cans, add paint-soaked beans (or pebbles) and put the tops on.

In this art meets science activity, learners pack silver, ball-shaped ornaments in a single layer in a box to create an array of spherical reflectors.

In this activity, learners explore the possibilities of clay as a natural material.

In this mechanical engineering activity, learners design shadow puppets with moving parts and use them to tell stories.

In this activity, learners explore light, color and rainbows by making their own rainbow glasses.

This activity guide features three related explorations to help learners ages 3-6 investigate shadows via the following science concepts: A shadow is made when an object blocks the light; you can chan

In this activity, learners make cool boxes out of old (or new) greeting cards or postcards.

Heat makes some materials expand, and it makes others shrink.

In this activity, learners create and reveal secret messages written with invisible ink! The invisible ink is actually a baking soda solution, and the magical revealing liquid is fruit juice.

In this fun, hands-on autumn activity, learners experiment to discover whether the colored substances in leaves can be separated from the leaves.

In this two-part activity, learners map a navigation plan to get from Earth to Mars and back. In activity one, learners represent the orbital paths of Earth through dance and dramatic movement.

In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

In this chemistry activity, learners witness an exothermic reaction, while making their very own, completely usable sidewalk chalk. This is also an excellent activity for exploring color mixing.

Students design and build their own parachutes in this hands-on engineering project.

Learners use shop tools and various materials to construct a magnetic spinner and a compass.

In this math-based activity, learners will experiment to find how height and angle affect spatter and then use this knowledge to solve a crime.

In this activity related to microbes, learners create scale models of microorganisms and compare relative sizes of common bacteria, viruses, fungi and protozoa using metric measures: meters, centimete

In this activity, learners construct a device that allows them to view 2-D images in 3-D.

In this delicious activity, learners get to make, taste-test and compare their own "brands" of homemade strawberry ice cream.

In this archaeology activity, learners make observations and conduct an experiment to demonstrate the effect saltwater has on artifacts.
