DNA is the thread of life. Encoded in its genetic sequence is the information that makes each of us unique.

This fun and simple hands-on astronomy activity demonstrates the shadow of the Earth as it rises as a dark blue shadow above the eastern horizon.

This is an educator-led demonstration of microarray technology using a model created from a pizza box and ping-pong balls.

In this activity, learners investigate the touch sensory system and discover how to plan and carry out their own experiments.

In this two-part outdoor activity, learners conduct a population census of squirting clams on a beach or mudflat, and investigate the clams' natural history.

In "Chemistry is Colorful" learners explore different materials through paper chromatography.

In this activity, learners will explore the chemistry of cooking. They will learn about--and observe--the Maillard Reaction as they make their own browned butter.

This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

In this laboratory activity, learners design an experiment to evaluate how environmental factors influence the growth of molds.

In this activity, learners will use magnets and household items to create a structure that allows paperclips to appear like they are floating.

In this activity, learners discover the principles of edible glass by making a supersaturated sugar solution.

In this simulation of natural selection, learners use binder clips in three different sizes to represent the diversity of beak sizes in a bird population.

In this activity, learners explore how engineers have developed sorting systems which integrate into manufacturing and packaging processes. Learners explore how coins are made.

In this activity, learners construct hail-proof houses using recycled materials to discuss storm readiness and safety.

In this activity, learners explore how product design differences can affect the success of a final product -- in this case a bag for holding candy.

In this optics activity, learners examine how polarized light can reveal stress patterns in clear plastic.

Cool off in the heat with this project! Learners use simple materials to build a fan that runs on a motor.

In this long-term activity, learners make a home for a colorful community of microorganisms.

Create gas with a glass of water, some wire, conductors and a battery! You will be separating water (H2O) into oxygen and hydrogen.
