Energy Transfers

These four videos represent my best explanations of energy transfers:

MESSAGE FAN- Chemical to Motion to Motion and Chemical to Light (Motion and Sound as Byproducts)

ELECTRO LAMPS- Electrical to Motion to Gravitational and Electric to Light(Heat is a Byproduct) 

ENERGY BALL- Heat to Chemical to Electrical to Sound(Motion is a Byproduct)

PULL BACK CAR- Motion to Sound to Gravitational and Sound to Motion(A different Sound energy is a Byproduct)

Reflection/Synthesis Questions:

1. What was your favorite station? Why?
2. Which object was most difficult to figure out?  Why was it so hard to figure out the energy transfers in this object?
3. Why did you choose the four videos above? What criteria did you use to select those?
4. Was it always possible to know for sure what kinds of energy transfers occurred

Answers:

1. My favorite station was the electro lamp and ball. It was my favorite because I loved the electro lamp that had all different colors. Also another reason why it was my favorite station was because I thought that it was cool that all of the electro lamps and ball were different. And that is my answer to question one.
2. The hardest station to figure out was the energy ball. The energy ball was the hardest one to figure out because whenever we thought we knew it Mr.Solarz would come back up to me and Molly D and give us somethingto figure out. Also if you think I'm blaming Mr.Solarz I'm not. And that is my answer to question two.
3. I chose the videos up above because I thought that they were the hardest ones to figure out. The criteria that made me choose the videos I chose was because they were our hardest thinking. And that is my answer to question three.
4. It wasn't always possible to know for sure what kinds of energy occured. For example the energy ball, me and Molly won't know for sure if we got it right unless we maybe put a tiny camera next to the motor. And that is my answer to question four.
