Energy transfers

These four videos represent my best explanations of energy transfers:

Fountain-electrical to motion to Gravitational to sound to motion 

Pullback cars-Elastic to motion to sound 

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?

Love thermometer- Heat to chemical to motion  ​

Plasma rocket lamp- Electrical to light to motion to sound  

Answers 

1. My favorite station was the fountain why because it was so cool to see how it works and try to figure out what the energy transfers are of the fountain in the back of the room. 
2.The hardest energy object was the color changing beads when you put them up to the lamp and first of all my partner and I could not see what was happening to the beads but than me teacher told me and my partner what it was doing.
3.I selected those because I think those sho the most work on this project and my partner and I really thought they had a lot of our good work in them. 
​4.No because not every thing we try to figure out is always correct but some of the objects are not always made that way and made for that but the fountain is made for a purpose and it is for decoration and to listen to over night and it might even help you fall asleep.
