The Effects of Gold and Silver Nanoparticles on Brine Shrimp: A Toxicology Study
Who doesn't love gold and silver? Brine shrimp, that's who! Learners conduct an experimental lesson to monitor the toxicity of gold and silver nanoparticles on brine shrimp. They synthesize solutions to expose the brine shrimp to and...
Curated OER
Semipermeable Membranes and Bioaccumulation
Beginning biologists place a drop of food coloring into water of differing temperatures to observe the effect on the diffusion rate. They remove the shells from raw eggs and then experiment with osmosis over the remaining membranes....
Curated OER
Exposure!
Young scholars investigate that chemicals may affect different people in different ways. They also realize that their perceptions of dangerous materials may not be realistic and that the news media may not provide all the information...
Curated OER
Chick Chock's Pollen Problem
Students analyze how allergens effect the body and how air borne substances can effect people.
Curated OER
Toxicology Puzzle
For this toxicology worksheet, students complete a crossword puzzle given 27 clues about terms related to toxins and the exposure to toxins.
Curated OER
Fertilizers, Pesticides and Human Health
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...
Curated OER
The Dose Makes The Poison
Students observe beakers of water that contain different amounts of a mystery chemical. They discuss how each amount of the chemical might affect them if the chemical was beneficial or harmful to their bodies.
Curated OER
Chemicals, Chemicals, Everywhere
Students divide substances into categories: made of chemicals/not made of chemicals, synthetic/naturally occurring, and toxic/nontoxic. They observe a mystery chemical and determine what precautions they need to take when handling an...
Curated OER
What is the Risk?
Students investigate the 1950's pollution tragedy in Minamata, Japan. The elements of dose, response, individual susceptibility, potency, and threshold of toxicology are explored in this lesson.
Curated OER
Toxic River
Students explore environmental safety by participating in a class game. For this toxic chemicals lesson, students discuss the effect chemicals have on our environment and how to best protect against their dangers. Students participate in...
Curated OER
Introduction to Toxicology
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.
Curated OER
Environmental Hazards
Students identify environmental hazards on a simulated field trip. They analyze the exposure and suggest methods to eliminate or reduce exposure to toxic sources.
Curated OER
Toxicology 2: Finding the Toxic Dose
Young scholars brainstorm with group partners to decide upon a chemical they would like to test, and outline a procedure for their investigation. They then present in groups their ideas to the rest of the class as well as the chemical...
