Get big results out of a small-scale lab! Young chemists observe the electrolysis of sodium sulfate using a microscale experiment. A colorful indicator solution combined with the production of gas bubbles yields a variety of observations...

On Earth, a candle flame points up, but on the International Space Station, it forms a sphere. Young scientists practice their skills by recording observations before, during, and after a candle burns. Chemical and physical...

Mirror, mirror, on the wall ... who's the best chemistry teacher of them all? You'll get the vote for certain after your class completes the Silver Mirror experiment! Partnered pupils use Tollen's reagent and glucose to silverplate a...

Immerse your chemistry class in the world of organic chemistry! Science scholars isolate acetaminophen from an over-the-counter sample during an intense and interesting lab. Groups use many different separation and analysis techniques to...

What do budding scientists know about moles and reactions? Using an attention-grabbing lab experiment, young scholars collect data to apply the law of conservation of mass to predict the mass of gaseous products. They examine several...

Light a fire in your pupils! Scholars conduct a flame test and observe the emission spectra of several different salts in an enlightening hands-on investigation. They use their observations to make comparisons and conclusions about the...

Watch as acids and bases put smiles on their faces. Young chemists learn the concept of acid-base titration firsthand in a microscale experiment. Working groups collaborate, titrate, then use their data to determine the concentration of...

Sometimes the simplest experiments leave the biggest impression! Introduce young chemists to the Cartesian Diver by having them make one of their own. Use the Diver to further their study of liquids and gases, as well as compression.

Is artesian water designed to be better, or is it just from wells similar to those in the city of Artesium? This experiment looks at many different types of bottled waters, including artesian. Using a soap mixture, scholars test to see...

Does mass change during a chemical reaction? Demonstrate the Law of Conservation of Matter while encouraging class members to be creative with a two-part lesson. First, learners use Alka-Seltzer® tablets and water to demonstrate the...

Do all liquids evaporate at the same rate? Young scientists observe the evaporation rate of three different liquids. They measure the time, the temperature, and the change in energy. After comparing the chemical formulas, scholars...

What better way is there to introduce conservation of mass than a few simple experiments? Young chemists conduct two chemical reactions, take the masses of reactants and products, then compare their results to determine...

Through two investigations, life science learners determine whether or not yeast is alive. They perform tests for metabolism by providing sugar and observing if gas is produced as a byproduct. They incubate some of the sample for at...

Processed foods use inorganic compounds for flavoring and preservation. This take-home laboratory challenges scholars to find 20 different compounds identified on the labels of foods to list on their data collection sheet. The activity...

How do green plastics reduce waste and environmental pollution? Budding scientists create and test a variety of compounds used in green plastics during an insightful experiment. Beginning with startling statistics and ending with...

Scientists can't observe bonds breaking or forming, so how do they distinguish between exothermic and endothermic reactions? Young scholars complete two experiments to do just that. They monitor temperature change and calculate the...
