  1. Agenda 04-10-2014 Introduction Homework Activity 53: Home Energy Use

  2. Homework • Work on the “Recycled Car” Project • Car • Report • Presentation

  3. Introduction Introduction Unit D Energy: Objective • Identify terms related to “energy”.

  4. Activity 53: Home Energy UseObjective Students will be able to: • Select a more energy-efficient home based on its energy use.

  5. Activity 53: Home Energy UsePurpose Students will be able to: • Use energy more efficiently.

  6. Activity 53: Home Energy Use • Set up Activity 53 (pp. D4-D7). • Science words: energy, trade-off. • Read the Introduction (p. D4).

  7. “Comparing Energy Use in Two Similar Homes” (Steps 3 & 4, p. D5)

  8. What is Energy? • Difficult to observe but you can observe its effects. • Energy can make things or matter: • Change • Move • Do work

  9. Kinds of Energy • Potential • Stored energy that can transform into kinetic. • Kinetic • Energy due to motion.

  10. Activity 53: Home Energy Use Steps 1 (p. D5) • List 7 typical household activities where you see energy in use (Journal). • Television • Phone charger • refrigerator • Lighting • Microwave • Toaster • Flat ironing your hair

  11. Activity 53: Home Energy Use Steps 2 (p. D5) • Order the activities from the one that uses the most energy (first) to the one that uses the least energy (last) • Read the Introduction (p. D4). • Refrigerator (uses the most energy) • lighting • television • microwave • ironing your hair • toaster • phone charger (uses the least energy)

  12. A Less energy for heating is needed B Less energy for cooling is needed B Less hot air moves out/in the house B Less hot air moves out/in the house Allows less exposure to sunlight A B Gas heater uses less energy A Central AC uses less energy B More high-efficient appliances B More fluorescent lightbulbs Taller vegetation B “Comparing Energy Use in Two Similar Homes” (Steps 3 & 4, p. D5)

  13. Activity 53: Home Energy Use Step 5. • Which house you think consumes less energy? Explain using evidence from table. Home A, Texas Home B, New York

  14. Independent Work • Work on the “Recycled Car” Project • Car • Report • Presentation
