How do you measure a bubble when it's floating? You can't really, but in this activity, learners can measure the diameter of the ring of suds a bubble leaves on a flat surface.

This activity shows you how to make amazing crystal spikes using Epsom salt and the sun.

In this activity, learners make film canister rocket ships. A fin pattern is glued onto the outside of the canister, and fuel (water and half an antacid tablet) is mixed inside the canister.

Visitors observe a tray holding a crystal-covered brick. The crystals were created by evaporation of a solution containing liquid bluing, ammonia, and salt.

In this activity, learners create a cool floating animal using the science of magnetism. Learners discover what happens when a piece of magnetic metal enters a magnet's field.

In this activity, learners discover how a cabbage juice indicator helps identify acids and bases, and how iodine indicates the presence of starch.

In this activity, learners explore the process of condensation.

In this activity, learners explore how the application of nano-sized "whiskers" can protect clothing from stains.

In this activity, learners use transparent tape and polarizing material to create and project beautifully colored patterns reminiscent of abstract or geometric stained glass windows--no glass required

This is part 3 of the three-part "Crayon Rock Cycle" activity. Before starting this section, learners must have completed part 1: sedimentary rock and part 2: metamorphic rocks.

In this activity on page 8 of the PDF, learners make a slimy substance very similar to mucus, and sprinkle it with glitter to imitate the way that allergens are trapped.

In this activity, learners create a "mini sky" in a glass of water in a dark room.

This fun and simple hands-on astronomy activity lets learners experiment with a bucket, stretchy fabric, marbles, and weights to discover some basics about gravity.

In this introductory activity and demonstration, learners are introduced to the concept that different substances react chemically in characteristic ways.

In this activity, learners explore how sound travels through solid objects better than through air. Leaners attach a metal clothes hanger to a piece of string and hold it to their ears.

This fun and simple hands-on astronomy activity describes techniques scientists use to find planets orbiting other stars.

In this lesson, learners cut paper into very small pieces to explore the small size of quarks, the smallest thing we know of on Earth.

Using information from the My Place in Space lithograph, learners write and/or draw a postcard to friends and family as if they had gone beyond the interstellar boundary of our Solar System, into the

In this activity, learners interact with whale artifacts such as replicas of skulls, bones, teeth, and baleen (hair-like plates that form a feeding filter).

In this activity, learners build their own rockets from paper, coffee stirrers, and tape. Learners discover that when anything flies, air pressure is always involved.
