2. SCIENCE STARTER  DO THE SCIENCE STARTER  TAKE 2 MINUTES  YOU ARE SEATED AND SILENT  TAKE OUT YOUR JOURNAL AND TURN TO YOUR HOMEWORK FOR MY CHECK

3. 1 ST SCENARIO  PHET SIMULATION OF AN ENERGY SYSTEM PROVIDED BY A BIKER

4. TAKING NOTES  USE THE JOURNAL TO TAKE NOTES.  TODAY NEW MATERIALS RELATE TO YESTERDAY AND TODAY CONTENT.  YOU MAY TAKE NOTES ON FEB 4 AND 5 DATES

5. VOCABULARY  THERMAL ENERGY  CHEMICAL ENERGY  KINETIC ENERGY  POTENTIAL ENERGY

6. WHAT IS ENERGY?  DEFINITION:  ABILITY TO DO WORK  WHAT ARE THE DIFFERENT TYPES?

7. DIFFERENT TYPES OF ENERGY  CHEMICAL ENERGY (CHEMICAL POTENTIAL ENERGY)  ELECTRICAL ENERGY  ELECTROMAGNETIC ENERGY  THERMAL ENERGY  HEAT ENERGY  MECHANICAL ENERGY  NUCLEAR ENERGY

8. CHEMICAL ENERGY  ENERGY STORED IN CHEMICAL BONDS BETWEEN ATOMS  CHEMICAL ENERGY IS RELEASED WHEN CHEMICAL BONDS ARE BROKEN DURING A CHEMICAL REACTIONS

9. THERMAL ENERGY  THE RANDOM MOTION OF ATOMS AND MOLECULES

10. HEAT ENERGY  HEAT OR HEAT ENERGY IS  TRANSFER OF ENERGY (USUALLY THERMAL ENERGY) FROM A BODY OF HIGH TEMPERATURE TO A BODY OF LOW TEMPERATURE  In other words – flow of energy from hot to cold

11. SPECIFIC HEAT CAPACITY  Specific heat capacity is the amount of heat required to raise the temperature of 1 gram of a substance by 1 Kelvin (K).  Example:  water is about 4.187 kJ/kg K  Human is about 3.470 kj/kg K

12. CONVERTING TO K  K = C + 273 DEGREES

13. WHAT IS TEMPERATURE?  MEASURE OF THE AVERAGE KINETIC ENERGY OF THE PARTICLES IN A SAMPLE OF MATTER  TEMPERATURE IS NOT A FORM OF ENERGY

14. POTENTIAL ENERGY  STORED ENERGY  ENERGY DUE TO POSITION, COMPOSITION, OR ARRANGEMENT. ALSO ENERGY ASSOCIATED WITH FORCES OF ATTRACTION AND REPULSION BETWEEN OBJECTS

15. KINETIC ENERGY  ENERGY OF MOTION

16. HOMEWORK = JOURNAL SUMMARY  SUMMARY 5 MAIN POINTS FROM TODAY LESSON IN YOUR JOURNAL

17. AIM PROMPT  WHAT IS THE BEST ENERGY SSYSTEM TO MELT ICE FOR WASHING? Use the RACE format (A paragraph of at least 3 sentences). Use evidence from the lab to support your claim.
