In this activity, learners create a water prism to break light into the seven colors of the rainbow.

In this optics activity, learners make a lens and explore how the eye manipulates the light that enters it.

In this activity on page 6 of the PDF, learners dissolve Epsom salt in water and discover that the resulting solution can be used to create a work of art.

In this activity, learners make a foam packing peanut "flink"--neither float away nor sink--in water. Learners experiment with materials to make a Flinker that "flinks" for 10 seconds.

In this activity, learners use simple materials to create giant bubbles.

Learners apply their knowledge from a previous study to identify different liquids--water, corn syrup, and vegetable oil.

In this activity, learners follow a recipe to make hollandaise sauce. Learners discover how cooks use egg yolks to blend oil and water together into a smooth mix.

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

In this optics activity, learners use glass and water to demonstrate total internal reflection (TIR).

In this quick activity, learners explore how blubber protects animals from the cold by making a "blubber mitt." Using cooking shortening, two zip-top sandwich bags, and duct tape, learners simulate bl

In this activity, learners explore the chemical reaction between water and effervescent antacid tablets. This hands-on activity models how a material can act differently when it's nanometer-sized.

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

In this activity, learners try to revive wilted celery. Learners discover that plants wilt when their cells lose water through evaporation. Use this activity to introduce capillary action.

Learners observe and record what happens when they manipulate bottles containing a liquid (water or corn syrup) and one or more objects (screw, nail, paper clip).

In this ocean engineering activity, learners explore buoyancy and water displacement. Then, learners design models of deep sea divers that are neutrally buoyant.

This is a quick activity/demonstration that introduces learners to the concept of index of refraction. Learners place stirring rods in a jar of water and notice they can see them clearly.

In this demonstration, learners observe how liquid nitrogen both boils and freezes ingredients to make ice cream in two minutes.

In this quick activity/demonstration about density, learners examine what happens when two cans of root beer--one diet and one regular--are placed in a large container of water.

Visitors observe a bottle with a balloon attached around the mouth. The bottle contains a solution of yeast, sugar, and water.

This is a chemistry lab activity about solutions (page 7 of the PDF). Learners see firsthand how chemicals in a solution can combine to form an entirely different substance.
