  1. Good Afternoon! Have out your Analysis Questions #1-6 Act. 61 out to review.

  2. Agenda Objective Review Act. 61 Analysis Front Load Response Set up Act. 62 Act. 62 HOmework

  3. Objective Students will be able to record and calculate the amount of thermal energy that is transferred to an ice cube.

  4. Act. 61 Analysis Pg. D-46 Analysis #1-6

  5. Analysis #2 The temperature of the final temperature went smaller. Analysis #3-Unequal volumes were mixed, the final temperature compared to starting temperature since you were using less cool water for exp. 2 and less hot for exp. 3

  6. Analysis 4 The thermal energy decreased since the cool water was added to the hot water. Thermal energy is still there.

  7. Analysis #5- the cool water increased, the hot water temperature decreased. By adding more or less cool or hot water.

  8. Analysis #6- thermal energy is still around the cup and water system

  9. #6- Thermal energy is lost since you are adding cool water.

  10. Front Load Response What is Quantifying Energy? Share with your partner in your group Volunteers share to the class.

  11. Act. 62:Quantifying Energy Date: 5/15/14 Challenge Question: Getting Started: Is the temperature the same in both (hot & cold) cups? Do the waters in each cup have the same amount of thermal energy?

  12. Introduction pg. D-47 Glossary: 1. Quantifying Energy-write in your own words what it means Review last sentence of intro Challenge Question: How much energy does it take to melt an ice cube?

  13. List ways to measure the energy is takes to melt ice Time temperature (thermometer) Graduated cylinder

  14. Materials pg. D-48 Safety: Write in own words Quantifying Energy Formula Procedure: Read Steps # 1- 6 Create a data table to record your results Title: Volume of water starting temp Final temp Temp change Quantifying energy formula Quantifying energy (energy lost) Observation

  15. Procedure Getters: Get bin of materials Procedure Captain: Read steps with your group I will pass out the ice cube to each group when ready! Don’t take out ice cube from bag. Follow & Complete steps #1-6

  16. Complete Step # 7 & 8 Use formula: Energy Released= Temp. change of water X mass of water Hint: 1 ml of water weighs 1 gram

  17. Energy Transferred

  18. Complete data table Complete Analysis #1-5 Complete steps #7 -9 use the formula

  19. Homework Exit Slip • Analysis #1-5- pg. D-49 • Extension Question Extra Credit • Act. 62- answer challenge question • Please complete and answer with complete sentences and give data and vocabulary
