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...

Colorful lead compounds never fail to impress! Solubility scholars examine a series of double replacement reactions involving lead nitrate and record their observations. The second part of the experiment illustrates the differences...

In this catalysts worksheet, students use transition metal ions to catalyze oxidation reactions of iodide ions. Students measure the rate of the reactions by measuring free iodine as a product.

Tiny particles can provide big learning opportunities! Middle school scientists explore the world of nanoparticles through reading, discussion, and experiment. Collaborative groups first apply nanotechnology to determine water...

Lost an electron? You should keep an ion them. Young chemists learn qualitative analysis in the second instructional activity of an 11-part chemistry series. After observing reactions of simple salts, the teacher provides pupils...

Fuel cells are being called the "energy source" of the future. Allow your high school chemistry class to construct a miscroscale fuel cell, complete with all components to generate energy. This engaging activity will allow them to apply...

Several factors affect the rate of a chemical reaction including temperature, surface area, and concentration. Using an experimental approach, learners explore the effect concentration has on this rate while maintaining consistency with...

High schoolers test wood splints that have been soaked in mystery solutions to identify the different colors it produces when lit. The lesson concludes with a reading passage and analysis questions.

How does carbon dioxide affect the world's oceans? The final installment in a series of six lessons has pupils research ocean acidification, then conduct an experiment to witness the delicate balance that exists in our seas. Materials...
