- Lesson 3—Dose-Response Relationships by danielle_blenkhorn — last modified 15-04-2009 19:57
- During this lesson students complete their observations from the investigation made on the germinating seeds. Students then report their results on a graph which shows the dose-response curve for their chemical. Students then compare data throughtout the classroom learning how to analyse in order to determine threshold and potency.
- Lesson 6—Environmental Hazards by danielle_blenkhorn — last modified 15-04-2009 19:57
- Students are to use knowledge and information gained through previous lessons to solve a scenario. Using fact sheets to learn about hazards and health reactions to a range of chemicals, students aim to solve to problem and recommend ways to minimise or eliminate exposure.
- Lesson 2—The Dose Makes the Poison by danielle_blenkhorn — last modified 15-04-2009 19:57
- Students investigate different amounts of chemicals and recognise the total amount as a dose. There is then a class discussion on how different doses may be beneficial or harmful to their bodies. Students then set up investigations to test the effects of different doses of chemicals on seed germination.
- Lesson 1: Chemicals, Chemical Everywhere by danielle_blenkhorn — last modified 15-04-2009 19:57
- Teacher and Students discus how their concepts of chemicals may differ to scientiific definition. Students observe an unknown chemical and brainstorm precautions that may need to be taken when handling the chemical. Students read case studies, that describe real exposures to chemicals.
- Lesson 4—Individual Responses Can Be Different by danielle_blenkhorn — last modified 15-04-2009 19:57
- Now that students are aware and understand that the variety of responses among seeds exposed to the same dose of chemical is due to individual susceptibility. Students conduct an investigation into their own susceptibility to caffeine and compare individual responses.
- Lesson 5- What is the Risk? by danielle_blenkhorn — last modified 15-04-2009 19:57
- Students apply their growing understanding of the concepts dose, response, individual susceptibility, potency, and threshold to a study on the 1950s tragedy in Minamata, Japan. Stents learn how to assess the risk of individuals to specific chemical hazards and investigate methods to manage risks.
| Description: | This involves a six lesson program developed to teach students the major concepts that relate to the relationship between chemicals in the environment and human health. Also helps develop students understanding of the influence of chemicals on the health of living organisms.
