No need to go to Ollivanders to buy a magic wand. In the chemistry lab activity, young magicians mix chemicals to create combustible compounds. By applying these compounds to an iron wire, they create magic wands.

After reading "Aquatic Alchemy," an article about recapturing water for reuse when in space, your class will use calcium hydroxide or hydrated lime to purify cloudy water. Geared toward high school chemistry or environmental science...

Sixty multiple choice questions cover the entire gamut of chemistry concepts. This is the local section of the U.S. National Chemistry Olympiad, where your chemistry candidates take a shot at entering the national competition. They...

The National Chemistry Olympiad exams are comprehensive tests covering an entire  year of chemistry concepts. You can use them as practice for competing in the challenge, or simply as a review, or as an actual final exam for your...

Do your high school scientists know the four methods scientists use to communicate information? A simple experiment discovering the relationship between gas pressure and volume allows pupils to practice all four. After completing the...

Here is a thorough lesson on safety in the chemistry lab. Chemists review a detailed list of safety rules, draw the layout of the laboratory area to include emergency equipment, identify hazard warnings, and consult the MSDS in order to...

Students investigate the properties of water. In this chemistry of water lesson plan, students observe a demonstration of the properties of water using sand, sugar, oil, vinegar and salad dressing. Students experiment with water, pepper,...

Public health trainees read and write a summary of the article, "A Whiff of Danger". The article is not available through the link, but can be found on the National Center for Biotechnology Information website. After summarizing,...

Hopefully by the time high schoolers are enrolled in your chemistry class, they are skilled with unit conversion. It does not hurt, however, to take an hour early in the school year to review this vital skill. This plan simply provides a...

Students evaluate different cosmetic products. For this chemistry lesson, students determine the physical and chemical components of their samples. They perform various test such as pH, viscosity, conductivity and formulate a conclusion...

Learners explain how the elements are arranged in the periodic table. For this chemistry lesson, students determine the subatomic particles for certain elements. They research the physical and chemical properties of an element they chose.

A kaleidoscope is constructed using polarizing polymer paper and then low-density polyethylene, high-density polyethylene, and polypropylene are all melted onto individual glass slides and examined through a microscope. The intent is to...

Does the size of a sample change the physical properties of that substance? It turns out it can! Young scientists combine physics and chemistry to synthesize CdSe quantum dots and record their color properties. Learners should...

Silver pennies and copper nickels are made possible by applying some chemistry. Learners use electrolysis to coat a penny with zinc sulfate and a nickel with copper sulfate. Their investigation builds an understanding of electroplating...

Chemistry classes pretend to be consultants to a grocery story trying to decide what polymer to use for therir new non-paper bags. They prepare tensile bars and use them to test plastic film samples for strength and stretchability. Both...

Students create a painting that clearly exemplifies the use of primary pigments to make secondary pigments. They demonstrate the distinction between value and saturation. They explain the affect of adjacent colors on each other and...

Students compare the characteristics of a fired porcelain sculpture to the clay used to create it. They discuss the physical and chemical changes that occur in the clay as it is heated and then create their own clay sculpture. This...

Students make ceramic sculptures to understand how clay works. In this sculpture lesson, students learn about porcelain sculptures to understand how heat can turn clay into a hard ceramic surface. They then experiment with clay to make...

Eighth graders identify the types of bonds elements form. In this chemistry lesson, 8th graders represent valence electrons with dot structures. They draw and label different atoms.
