This hands-on activity demonstrates how a material can act differently when it's nanometer-sized.

In this chemistry demonstration, learners investigate the rule "likes dissolve likes" by combining three, immiscible liquids to create a colorful density column.

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.

In this physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass.

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

In this activity about combustion and energy, learners observe a burning candle in a sealed jar and the burning of white sugar.

Learners write their initials by applying different clear "magic ink" solutions to separate pieces of paper and then "develop" the inks with other clear solutions.

Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer.

In this activity, use standard playing cards to introduce learners to cellular interactions such as cell to cell recognition and signal and receptor specificity.

In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.

In this activity, learners make self-assembled polymer spheres.

In this group activity, learners will explore the characteristics, functions and uniqueness of the mangrove tree.

Learners create beautiful fluid motion. They explore fluid dynamics, surface tension, solubility, and buoyancy while mixing liquids together.

Learners use Benedict’s solution and heat to test for the presence of simple sugars in glucose, sucrose, starch, and starch combined with amylase.

This kinesthetic science demonstration introduces learners to four states of matter: solid, liquid, gas, and plasma.

In this activity, learners build a model of a self-sustaining habitat (growing grass and beans from seeds).

In this activity, learners explore how the application of nano-sized particles or coatings can change a bigger material’s properties.

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 activity, learners investigate vitamin C.

In this activity, learners will discover how the thin layers of amphibians' skin allow water and other chemicals to pass through it.
