Many people get water from a source deep underground, called groundwater.

Most people will break a bone in their body at some point in their life, but how much force does it take to break one?

Learners build a simple one-cell battery and use an ammeter to measure the flow of current.

DNA is the thread of life. Encoded in its genetic sequence is the information that makes each of us unique. This activity allows you to see long, stringy strands of DNA extracted from wheat germ.

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.

DNA is the thread of life. Encoded in its genetic sequence is the information that makes each of us unique.

In this hands-on activity, learners use heat to shrink samples of polystyrene plastic (#6 recycle code). Learners compare the size and shape of the plastic pieces before and after shrinking.

In this investigation of reaction kinetics, learners alter the amount of iodate solution mixed with the same amount of starch solution.

This is an activity about robotics programming. Learners will discover how precise programmers have to be as they instruct a friend to make a peanut butter and jelly sandwich.

Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.

In "Chemistry is Colorful" learners explore different materials through paper chromatography.

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

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

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

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.

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.

Learners add acid rain (nitric acid) to two cups that represent lakes. One cup contains limestone gravel and the other contains granite gravel.

In this activity, learners explore the principles of magnetism by observing how various materials interact with magnets and superconductors.
