Insulated Bottles

9/26/2014

What was your maximum temperature (use your Data Chart, not the picture)?
What was your minimum temperature (use your Data Chart, not the picture)?
What is your range? If you had any penalties or gifts, include those in your total.
What materials did you use in your insulated bottle (type them in order from your first layer, second layer, and third layer.)? Why did you choose the materials that you did?
What are some materials that you didn't choose? Why didn't you choose them?
Explain any blips on your graph (if you have them). Why do you think it did that?
Is an insulator a good or a poor conductor of heat energy? This is an important question, so really think before you answer it!

1.Our maximum temperature was 105 degrees.

2.Our lowest temperature was 45 degrees.

3. The range from our chart was 60 degrees.

4.The materials that we had use was polyester,aluminum foil,carpet insulator,nylon,wax paper,thick paper,and duck tape

5.We didn't choose bubble wrap and plastic wrap because we thought it wouldn't be a good insulator.

6.Yes we did have blips on our chart it happened by shaking the bottle in the water or stinking your hand inside the temperature changes.

7.An insulator is a poor conductor because it slows down the heat energy that is transferring through it.

Bamboo Rod
Silver: Aluminum Rod
Brownish Red: Copper rod
Gold Yellowish: Brass Rod
White: Plastic Rod

I think that the metals (Copper, aluminum, brass) will slide first. I think they will because I know that metals are good conductors. I think that bamboo and plastic will slide last because they are bad conductors.

Results:
1. Copper-2 seconds
2. Aluminum-7 seconds
3. Brass-85 seconds
4. Plastic-2,640 seconds
5. Wood-Did not even fall!

How did heat energy transfer to the butter in this experiment?
What connections can you make between this experiment and yesterday's experiment? "Both today's experiment and yesterday's experiment... The main differences were..."
How did your results compare to your predictions?
Which of the tested materials were the two best conductors? What is your evidence?
Which of the tested materials were the two worst conductors? What is your evidence?
Do you think water is a good or poor conductor? Why? Can you think of any evidence to support your answer?
Why do you think it matters which material is a good or bad conductor? How do we use conductors in our life?

1.The heat energy transferred through the rods that the butter was on. The rods were in the hot water, which held the heat energy.

2.Both today's experiment and yesterday's experiment used water and a temperature probe. The main differences were no food coloring today and we were using butter today.

3.My results were very close to my predictions.
4.The two best materials were the copper and the aluminum.My evidence was the seconds it took for the butter and the stick slid down

5.The 2 worst conductors or rods were the brass and the bamboo.My evidence was the second (right on top of the page) and the brass took 85 seconds and the bamboo took 2640 seconds.

6.Yes I think water is a good conductor because electricity can travel through water like electrolytes.

Transferring Heat Energy from Warm to Cold Water

What happened to the temperature of the cold water over time? What about the warm water?
What happened on the graph to show what happened with the water temperatures?
What did you notice happened at the end of the experiment?
How did the cold water get warmer? How did the warm water get colder?
Did the water go through the red Solo cup? How do you know?
Which direction did the heat energy move?

1.The things that we observed to the temperature of the hot and cold water over time were some of these. The cold water got warmer to the point that the cold water became warmer then the hot water and the warm water got colder then the cold water.
2. The things that happened on the the graph was the hot started way up on it and it got lower and lower. Then the cold went up until both of them were a couple degrees apart from each other. 3.They were only a couple degrees apart from each other. That's because they had the same amount of heat energy. 4. The cold water got warmer by pulling the heat energy out of the hot water and the hot water got the heat energy pulled out of it. 5. The water didn't but the heat energy did. The cold water would have turned redder and it didn't. 6.The direction the heat energy went was toward the cold water. That's because it was absorbing it.

Energy Transfer

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?
Which three stations do you feel very confident that you figured out correctly? Describe one and explain what made it so obvious.
Was it always possible to know for sure what kinds of energy transfers occurred?
Go to our classroom YouTube channel and spend a little time watching other students' videos of stations that you think you and your partner(s) might have gotten wrong. Try to find a group or two that explained a particular station better than you did. Which group do you want to give a shout out to for doing a good job explaining a particular station? List their names, the station they explained, and the URL to their video so I can watch it!

1. My favorite station was the Energy Ball because it was able to use energy passed from person to person and back to the ball. I liked that it used that energy to create fun sounds and light.
2. The Drinking Bird station was the hardest to figure out because it had a lot of energy forms. It was hard to figure out which kind of energy it was and putting it in the right order on the graphic organizer.
3.I felt that the suction cup frogs, the pull back toy car, and the hand held generator were easy to figure out. The frogs were easy because I know that elastic energy includes springs and you can clearly see the springs.
4.No, because you really had to think about it to get the right answer. Even when you think about it it's not always right, and it's really difficult to find.
5. I would like to give a shoutout to Lucas and Luke at the Pull Back Toy Car station. I thought they explained it very well and included the types of energy.

I would also like to give a shoutout to Kaela and Charlie for the Galileo Thermometer. They had a great explanation of the forms of energy.

Finding Eight Forms of Energy Around Westgate

Reflection & Synthesis Questions:

Where is energy found?
What forms of energy are easiest to notice? Which ones are hardest to notice?
Do some items possess more than one form of energy? If so, which ones?
Why is energy important?

Answers:
1. Energy is found in and around Westgate. It was found on the playground, in the hallways, and in classrooms.
2. Gravitational energy was easiest and light energy was hardest. With gravitational energy, all you had to do was lift something up. Light energy was hard because a lot of the items were very similar, like lights.
3. The sun, a swing, and a person possess more than one form of energy. The sun is light energy but also heat energy, a swing has gravitational and motion energy, and a person moving has motion and chemical energy.
4. Energy is important because it helps us live. Light energy helps us see, chemical energy fuels our bodies, and heat energy helps us not freeze.
