  1. Risk Analysis Erika Hernandez Supervisor: Dr. Robin Autenreith E3 Teacher Summer Research Program

  2. What is Risk? • Risk is the possibility of consequences involving mortality, morbidity, or injury to members of the public. • What risk do we take when we drive our vehicles?

  3. How much risk is safe? • There is no situation in which there are no risks, but every situation should be as safe as possible. • Our government allows a 1 in 1,000,000 risk for things out of our control. For example: The chance of coming into contact with radioactive material. • Thing we can control are allowed a 1 in 10, 000 risk. For example: The chance of being poisoned by a pesticide.

  4. Where is risk relevant for students? • Cosmetics • Detergents • Cell phones • Medications • Cleaning supplies • Pesticides • Herbicides • Transportation • EVERYWHERE!!!

  5. Poisons Surround Us

  6. Purpose • Enrichment for Chemistry and Biology curriculum. • Alert students of poisonous products in their environment. • Increase awareness of risks in everyday activities. • Enhance learning by using technology in labs.

  7. Background Knowledge Chemistry: Chemical properties - those properties a substance possesses because of its action or lack of action with other substances. Reaction with an acid, or reaction with oxygen (combustion) are just a couple of examples of chemical properties.

  8. Background Knowledge Biology: Cellular respiration - is the process of oxidizing food molecules, like glucose, to carbon dioxide and water. The energy released is trapped in the form of ATP for use by all the energy-consuming activities of the cell.

  9. Introduction Activities • Poison Proof House • Are You Cautious? • What’s That Say? • Hazard Symbols

  10. Measuring • How do we know when something is poisonous? • How do engineers measure this?

  11. Lab • Cellular Respiration and Toxins - Measures CO2 and O2 levels of germinating peas.

  12. Post Activities • Chemical Engineer • You Be the Engineer • Quiz – Using Hazard Symbols

  13. Extras • Poison Control • Tox Town • Mr. Yuk jingle • Mr. Yuk children's coloring activity • Household Product Database • EPA • Vernier
