Energy Transfers

2/8/2019

These four videos represent my best explanations of energy transfers:

Fountain - Electrical makes light and motion to sound motion to gravitational.

Pop-up-toy- motion to elastic to motion to gravitational.
(By product Sound when toy hits table)

Love thermomoter- heat to chemical to motion to gravitational.

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

Prejection alarm clock- chemical to electrical to motion electrical to light.

My favorite station was the dancing water speaker. This was my favorite station because it was probably the easiest to figure out, The electrical powered everything it powered the motion lights and sound.
The hardest object for me was probably the beads. This was really hard because there was so much going for the transfer, and the beads weren't changing color witch we had to identify how they changed color. So the beads were pretty hard.
I chose the four videos above because those videos me and my partner were the most focused on. We also did a better job of identifying the correct energy transfer.
It was not always possible to know for sure what types of energy occurred. I found it challenging four the fountain because me and me partner did not know if there was gravitational energy or not. We decided to say it was because the gravity was pulling the water down.
