Will this water source support life? Small groups test the chemistry of the water drawn from two different sources. They then compare the collected data to acceptable levels to draw conclusions about the health of the source. The...

Bubble, bubble, boil and trouble! What causes common substances like baking soda and vinegar to react the way they do? Welcome your junior chemists to the wonders of acid-base chemistry using a comprehensive and fun...

Using the natural pH indicator of red cabbage juice, groups determine the pH of different everyday liquids. As they work, pupils gain an understanding of pH that may help deal with contaminants in the water supply. 

An incredibly thorough lesson on vitamins, and how to keep one's body at peak health. Learners access a variety of excellent worksheets embedded in the plan that have them consider raw vs. cooked foods, a vegetable nutrition summary,...

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...

We use basic units of measurement to break down things and communicate clearly. The first lesson in an 11-part series teaches the proper way to measure various items. It starts simply with measuring the dimensions and areas of geometric...

Though the publisher designated this unit for use with third through eighth grades, this particular lesson would be best used with middle schoolers due to the specific measurement skills required. Basically, they set up the reaction...

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...

Upcoming chemists use chemical reactions to determine relative pH in two different acids. This is a terrific lesson for middle schoolers that can stand alone as a practice in precision and lab skills, or as part of the unit on chemical...
