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

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 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.

“Exploring Earth: Rising Sea” is a hands-on activity demonstrating ways to use topographical mapping techniques to track changes in sea level. The activity is connected to current NASA research.

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 about sea otters, learners make their own "otter whiskers" and use them to find objects underwater.

In this activity, learners turn an ordinary metal coat-hanger into a (very quiet) musical instrument.

In this chemistry activity, learners use spaghetti to explore density and chemical reactions.

In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.

In this activity, learners will put a set of containers in order by capacity. Would the tallest container hold more or less water than the wide, short one?

In this chemistry demonstration, learners will discover that phenolphthalein is an acid/base indicator. One learner will read a poem about four witches making a potion.

In this experiment, learners use a blow dryer and water bottle to observe and record changes in air pressure caused by changes in temperature.

In this demonstration/activity, water streaming through holes in the bottom of a suspended soda pop can causes the can to rotate.

In this activity, learners explore how air warms when it condenses water vapor or makes clouds.

In this quick activity, learners observe how wind creates ocean currents.

In this activity, learners use a laser pointer, empty soda bottle, rubber plug and water to demonstrate total internal reflection.

In this activity, learners explore clouds and how they form.

This interactive demonstration reintroduces learners to three states of matter (solid, liquid, gas), and introduces them to a fourth state of matter, plasma.
