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...

In this ethyl alcohol worksheet, students read about the characteristics of ethanol including the effects it has on the body when ingested and digested. This worksheet has 2 short answer questions.

Young scholars develop and run a laboratory comparing alcohol tolerance in flies with and without the ADH enzyme.

How does food coloring work? Classes watch a demonstration showing liquids dissolving in liquids. In groups, they then explore the ability of other liquids to dissolve in water (alcohol, mineral oil, and corn syrup) by setting up and...

Drugs can both help and harm depending on how they are used. Fifth graders complete a worksheet that provides background information on prescription drugs. They read the text and then describe why medication manufacturers label pill...

Students examine the effects on motor functions in mice. They make observations and graph their data. They analyze the data and draw conclusions in each of the three experiments.

Learners experiment to create a plastic solution. In this science lesson plan, students use sodium borax and polyvinyl alcohol to create their solution, then identify, discuss, and chart observations on the end product.

Young scholars investigate the process that occurs when liquids evaporaate. They test water and alcohol to determine which substance evaporates more quickly and relate the rate to energy changes.

Get your high schoolers thinking about the factors that lead to birth defects. They examine how environmental factors and personal choices can cause birth defects in unborn children. They discover the effects of various handicaps such as...
