The Dose Makes The Poison

Introduce learners to the debate format with an activity that uses the National Park Service's controversial Channel Islands restoration program as a topic. Class members learn how to generate provocative debate questions, how to prepare...

Students discuss non point source pollution and identify such sources within their communities. They use radish seeds as a bioassay to investigate pollution. They present oral reports on the results of their experiments.

High schoolers in chemistry or health courses look at the material safety data sheet (MSDS) and periodic table of elements to gather information about mercury and lead, two toxic materials that have been found in food products. They read...

Students discover they are made of elements in activities based on comparing the human body to the periodic table. In this science lesson students are engaged with 3 hands on basic chemistry activities. The students end the lesson by...

Students explore the science of toxicology and the relationship between a toxic reaction (response) and amount of substance (dose). They observe two demonstrations illustrating the concept of dose-response.

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...

Students define several vocabulary terms related to chemicals and toxicology. Students calculate chemical concentrations in water and explain the toxicological principles that govern safety of substances. Students conduct an...

Students investigate how toxic chemicals affect biological systems. They determine the toxic dose of a chemical that inhibits seed germination in a Brassica rapa. They investigate the effect of environmental tobacco smoke on human lung...

High schoolers explore sources of  pollution runoff and actions that can be taken to reduce runoff.  In this pollution lesson students complete a worksheet and see why bio-essays may provide a more realistic picture of toxicity.

Young scholars investigate the effect of a chemical (they choose) on the germination of seeds. They calculate % chemical concentrations in water, form a hypothesis, and discuss the ethics of using animals in biomedical research.
