  1. Warm-UpMay 7, 2013 • Write down the date and objective. • Objective: SWBAT explain the factors that affect the rate of a reaction by teaching part of a lesson. • Complete the following warm-up: •  If 250 grams of water is heated from 10oC to 30oC, the number of joules of heat energy absorbed is… • A sample of water is heated from 20oC to 45oC by the addition of 110 joules of heat. What is the mass of the water?

  2. Objective & Agenda • Objective: SWBAT explain the factors that affect the rate of a reaction by teaching part of a lesson. Agenda • Mystery Element • Unit 6 Tracking • Kinetic Demonstrations • Teaching Assignment • Presentations • Exit Slip

  3. Mystery Element Clues • It is an extremely heavy metal with a silvery-white color that accounts for the name quicksilver that is often given to it. • It is the only metal that is liquid at room temperature. • It used to be contained in thermometers.

  4. Mercury (Hg) • Mercury is rarely found as a pure metal in nature. • It used to be found in common household products: thermometers, barometers, thermostats, and fluorescent light bulbs. • It is an extremely toxic element. It combines chemically with enzymes in the body, causing them to lose their ability to act as catalysts for vital body functions. The vapor (gas) is much more harmful than the metal itself. • It can cause the loss of hair and teeth, loss of memory, and a general deterioration of the nervous system.

  5. HW 26 Review

  6. Unit 6 Tracking

  7. Kinetic Demonstrations • Fill out your observations as we go through each demonstration.

  8. Students  Teachers • Each group will be assigned a short section. • Your group will be responsible for teaching this material. • Read the section. • Take notes over the information • Determine the important information and how you will teach it to the rest of the class. • You can go on the internet to find more information on your topic. • Be prepared to present the information to the rest of the class.

  9. Teaching Assignments • Concentration • Page 537 • Surface Area • Page 537-538 • Temperature • Page 538 • Catalysts • Page 539-541

  10. Presentations • Speak loudly • Audience is taking notes and listening • Audience can ask questions at the end

  11. Exit SlipMay 7, 2013 • What is a catalyst? • How does temperature affect the rate of reaction? • How does concentration affect the rate of reaction? • How does surface area affect the rate of reaction?
