In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.

In this activity, learners use multiple thermometers, placed at different angles, and a lamp to investigate why some places on Earth's surface are much hotter than others.

This is an activity about a very important ingredient in most baked goods - gluten! Why is gluten so important? Without it, there would be nothing to hold the gas that makes bread rise.

In this design challenge, learners will create wind-powered contraptions to transport a load, such as a cupcake or another small object, and test to see if they work.

In this activity, learners explore how water behaves differently when it comes in contact with "nano sand" and regular sand.

This lab activity has learners create a pendulum with a one-second period.

In this activity, learners will make their own slushies and learn some of the science behind how the process works.

In this activity, learners will explore pendulum motion through scientific trials by using household items with different length strings.

In this activity, learners will make their own prism and use a glass of water to separate sunlight into different colors.

In this activity, learners investigate how inkjet printers produce tiny, precise drops of ink.

In this activity, learners create a colorful bookmark using a super thin layer of nail polish on water. Learners discover that a thin film creates iridescent, rainbow colors.

Learners can program a compass to draw a circle by itself using a Pico Cricket, some Legos, and lots of tape! Pico Cricket is required.

In this activity, learners explore temperature changes from chemical reactions by mixing urea with water in one flask and mixing calcium chloride with water in another flask.

This is an activity to do when there is a solar eclipse!

Bones are stiff, which helps us lift heavy things and walk around, but they are also somewhat flexible, which lets them bend slightly.

Doctors often send a sample of blood to a lab, to make sure their patients are healthy.

In this activity, learners will create their own simple shadow puppets, and experiment with light and shadow while playing with them.

In this activity, learners explore and compare the buoyant properties of materials found in nature and in human-made materials.

In this activity, learners explore electronics and motion by making a Scribbling Machine, a motorized contraption that moves in unusual ways and leaves a mark to trace its path.

This is written as a static display, but can easily become a hands-on experiment for learners.
