9. I can state how energy is transformed.

10.  I can use the law of conservation of energy to explain energy changes.

1. Do Now: What does food, fuel, batteries and coal all have in common?

2. Copy down the notes Ms Garlick makes about energy transformation. 

3. Level Up! Start at Level 1 and push the depths of your understanding of energy. 

   1. • Level 1: For each of the following actions, identify the energy transfer that is occuring. You may have more than one energy tranformation. 

        1. Hair drier 

        2. Riding a bike

        3. Playing piano

        4. Nuclear power plant

        5. Using a flash light

      • Level 2: Using the equation energy effiency = useful output energy/total input energy x 100, what would the energy efficiency of the toaster be if the input was 800 J but the useful energy was 520 J? 

      • Level 3: Explain what happened to the other 280 J from the toaster? Your answer should include the law of conservation of energy.

4. Mahi Choice 

   1. • Play Gimkit 

      • Work on homework
