Transferring Heat Energy

2/14/2019

Reflection Question:

How did the temperatures of the water in the red Solo cup and the water in the bucket compare at the beginning?
What happened to the temperature of the cold water over time?
What happened to the temperature of the warm water over time?
How did your graph show what happened?
After 15 minutes, what did you notice about the lines on your graph?
What happened to make the temperature of the cold water get warmer?
What happened to make the temperature of the warm water get colder?
Use your line graph to predict what the temperature of the warm and cold water would be after 10 more minutes. Record your predictions below. Why did you choose these temperatures?
Did the water go through the red Solo cup? How do you know? Can the food coloring in the warm water help you explain this answer?
Which direction did the heat energy move?

Answers:

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.

Reflection/Synthesis Questions:

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.

Answers:

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.
