In this chemistry demonstration, acid rain is simulated in a petri dish.

Do you have a hard time matching paint swatches with your furniture? When you consider human perception, color is context dependent.

In this activity, learners construct a model of DNA to better understand the structure of DNA and protein synthesis.

In this activity, learners discover the principles of edible glass by making a supersaturated sugar solution.

In this activity, learners look at and touch marine animal skulls to compare them and think about what they eat.

In this activity/demo, learners are introduced to the connection between medieval stained glass artisans and nanotechnology.

Use this Moon Map Guide to help learners identify features on the Moon, while looking through a telescope.

In this outdoor, beach activity, learners use tennis balls, water balloons and other simple devices to investigate the movement of waves and currents off a sandy beach.

Using electrolysis, learners produce hydrogen gas and oxygen gas from water molecules in a solution.

In this activity, learners are challenged to calculate their own weight on various planets using a scale and calculator. Older learners may be challenged to do so without using calculators.

In this activity, learners construct hail-proof houses using recycled materials to discuss storm readiness and safety.

Learners combine hydrogen peroxide with three different forms of potato: raw chunks, ground chunks, and boiled chunks.

Learners test solutions of water, sugar, salt, and hydrochloric acid for electrical conductivity. They immerse leads from a lighting device (a battery pack connected to an LED) into each solution.

Design a vessel that tests the limits of wind power given a set of off the shelf and recycled materials.

This activity encourages visitors to build an electroscope—a simplified version of one of the tools scientists use to study the invisible forces on Earth and in space.

A design challenge that takes paper airplanes into an entirely different direction: a magnus glider uses cups and and rubber bands to create a glider that uses the same forces that a curveball (from b

In this activity, learners observe mixtures of sand samples glued to note cards, and consider how sand can differ in size, shape, and color, and where it comes from.

"Molecules in Motion" explores how materials behave and change in a vacuum.

In this chemistry meets cooking activity, learners make carbonated, vanilla ice cream using dry ice and denatured ethanol, which are both inexpensive and accessible.

In this activity (on pages 49-54 of PDF), learners play with tangrams, a set of triangles, squares and a parallelogram that can combine into a larger square as well as all sorts of other shapes.
