Can gelatin (like Jell-O ®) change the speed of light?

In this activity, learners touch supercooled water drops with an ice crystal and trigger the water drops to freeze instantly.

In this fun chemistry activity (page 3 of the pdf), learners use cabbage juice to determine the pH of several substances.

This laboratory exercise is designed to show learners how DNA can be extracted from a chunk of thymus (sweetbread) or liver.

In this exciting and tasty chemistry activity which requires adult supervision, learners explore how chemistry affects a simple everyday activity like cooking.

Learners place an M&M candy in water and observe what happens. The sugar-and-color coating dissolves and spreads out in a circular pattern around the M&M.

Learners mix a variety of substances with red cabbage juice. The juice changes color to indicate whether each substance is an acid or a base.

In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.

In this activity (on pages 34-39), learners make a fairly detailed model of DNA using licorice and gumdrops.

In this demonstration about momentum, use physics to distinguish between a hard-boiled egg and a raw egg without cracking them open.

In this activity, learners explore the concept of permeability to better understand why amphibians are extremely sensitive to pollution.

In this chemistry demonstration, learners investigate the factors that increase the rate of dissolution for a solid.

In this cooperative learning activity, learners visit ten stations and are challenged to think critically about various conservation questions and issues.

In this activity related to rotational inertia (page 1 of the PDF under SciGirls Activity: Microgravity), learners will use a bit of scientific experimenting to test if open-faced peanut butter sandwi

In this activity, learners conduct tests for proteins, glucose, and starch.

In this activity, learners explore the forces at work in water. Learners experiment to find out what happens to pepper in water when they touch it with bar soap and liquid detergent.

In this activity, learners build edible models of Jupiter and Earth to compare their sizes and illustrate the planets' internal layers.

In this activity, learners create a gelatinous slime using guar gum powder and borax. Educators can use this simple activity to introduce learners to colloids.

In this activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.

In this physics demonstration, learners are challenged to break a raw egg just by squeezing it. Learners will be shocked by their inability to complete the deceivingly simple challenge.
