High school chemistry class members become "detectives for a day" and use the concept of paper chromatography to analyze a note left at the scene of a crime. Pupils test the ink on the note with a solvent, such as isopropyl alcohol, to...

To conclude a mini unit on the dissolving of M&Ms® candy coating, this lesson investigates whether or not the concentration of sugar in the solvent affects the dissolving rate. Consider having older science learners write their own...

Why does some ink bleed through paper, and other ink doesn't? Practice some paper chromatography to separate the colors from a pen with an interactive experiment for middle and high schoolers. Learners use a variety of solutions to track...

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...

Avoiding lab safety rules will not give you super powers. The lesson plan opens with a demonstration of not following safety rules. Then, young chemists practice their lab safety while finding the mass of each item in a mixture and...

Groups use alcohol and chromatography paper to separate the color components of black ink. The purpose of the activity is to allow the class to become aware that mixtures exist in hidden places. 

From molecules to nanotubes, an engaging unit explores the world of tiny science. Fifteen hands-on experiments and lessons engage young scientists as they learn chemistry. Discussions, worksheets, and data analysis reinforce the concepts...

Scholars find Earth won't support humans much longer and need to identify a planet with water to inhabit. They test four unknown samples and determine which is the closest to water. Then they explain and defend their results.

An educational lesson allows young chemists to test the solubility of different types of salt at various temperatures. Groups create a graph using data from unsaturated, saturated, and supersaturated solutions.

Your chemistry class is sure to love this experiment on column chromatography, as demonstrated with chalk sticks and felt tip markers. Pupils use sidewalk chalk (another inexpensive form of chalk stick) to demonstrate adsorption and the...

Here is a nice, clean wrap-up lesson for your chemistry class when they are studying chemical reactions . They experiment with different oils to make soap. To make it more fun, they are to imagine that they are part of a soap testing...

Thinking about designing a project for your social studies or environmental science classes? Use an overview of a project that prompts class groups to research an environmental issue.

Legal and illegal. Use and misuse. Risks and consequences. Myths and facts. Class members investigate the effects on the body of various drugs, including cannabis, nicotine, and alcohol.

Why are acids and bases important in our daily lives? Lead the class in answering this question, among others, as they experiment with pH paper and classify where various substances belong on the pH scale. They also taste common acids...

How do you engage pupils in a discussion about osmosis without leaving them overwhelmed? By providing them with the tools to perform an exciting experiment, and they will see osmosis in action! Young chemists and biologists use...

Don't be shocked when your class has a blast making their own batteries! Science scholars examine a dry cell battery, then design and construct a wet cell battery. The activity guides them through the parts of a battery, the variables...
