Heat #4

This post is the one you've ALL been waiting for!

The Heat Menu!!!

In the previous posts, I talked a lot about Climate Change, and so in this one I'll be talking about the Heat Menu Project we did, and in the next post, I'll be summarizing what we learned during these couple months.


I'll start by talking about the Appetizer, and explaining what we do.

The objective of the Appetizer part was to 'Write a summary a report using scientific method. For the conclusion please write of what you discovered during these labs.'

We chose to do Option 2, which was to complete Lab 2.

What we did was place one side of a bimetallic strip on a heated hot plate (the brass side) and draw what it looked like, and then we had to place it in the beaker of water. We did the same with the other side, (the zinc side) and drew what it looked like, and placed it in the beaker of water.

When doing this experiments, we found out that the brass side bent more than the zinc side, which basically meant that the brass side expanded quicker than the zinc side. This proved that our hypothesis was right-that the brass side would expand faster, because it was a better heat energy conductor.

We (Carson and I) also noticed that frying pans and ovens would work the same way: with different meals, some frying pans cool faster than others, as well as ovens.

The next part was the Main Course 'Write down what a good driving question question is and what you found for this experiment.'

There were two parts to this experiment: We had to write down what a good driving question would be, as well as write down our conclusions and what we found out from this experiment.

Driving questions are pretty important, because it helps us to actually stop, think, and wonder about the question, and it's challenging us, testing us, and it helps us think outside the box. Not only do these questions help us focus, it also helps us communicate the purpose of the project and/or experiment, and it helps us know what's going on in the class, as well as give us a sense of understanding.

When we, as students, read this question, it should also be able to peak our interests, and should be able to guide us. So, when we're in class, watching videos of Mrs Bumstead talking about the difference between heat, and temperature, we should be able to know WHY we're doing this...

But this all depends on whether the driving question is effective or not.


Onto the next part-THE DRINK!!!

(don't you just love my enthusiasm?)

We chose to do Option 2, and the point of it was to 'Make a brief summary of what you read.'

Option 2, was to read about how heat affects land, and so we had to summarize what we read. I won't go into details, (because honestly... **in a very quiet whisper** it's not that fun or interesting! **looks around quickly** and don't tell Mrs Bumstead I said that!) but it was basically talking about volcanoes, and magma, and the different layers of the Earth. It also began to talk about Rocks and Minerals, and how they help the surface of the Earth stay where it is, and no collapse.

Finally, we have our Dessert, and we chose option 5-which meant we had to do a Top Ten 'book' of how heat helps us live.

I'll name our top ten, and explain them briefly-

1. Heating Systems.
2. Ovens and other appliances.
3. The sun.
4. Fire.
5. Us.
6. Geothermal Energy.
7. Candles and/or matches.
8. Blankets.
9. Clothes.
10. A hot cup of tea or any hot drink.

Number 1. Heating systems-especially in the winter are really useful, and studies have shown that keeping warm in the winter can prevent things like pneumonia, heart attacks, and strokes.

Number 2. Ovens cook our food that we can't eat raw-like meat-and helps prevent things like worms, salmonella, and hepatitis E, which can all kill you, or damage your life in a serious way.

Number 3. The sun. The sun's rays provide food for the plants, like tomatoes, maple trees, corn... etc, with photosynthesis and all that, but without the sun, we wouldn't really have seasons either, or any types food really, because everything we eat, all started from plants-who get their energy from the sun!

Number 4. Fire provides warmth... and I think it's pretty self-explanatory.

Number 5. Us.
Even inside us, there is heat, and it keeps us warm in the winter... and warmer in the summer.

Number 6. Geothermal energy.
Geothermal energy is the heat from the Earth, and it's heat is used to heat the plants and the ground, so the plants don't die. Another good thing about this type of energy is that it's clean and sustainable, so it's actually very reliable.

Number 7. Candles and/or matches.
Not only do these provide light for us, but they provide us with heat, and the ability to make fires, to cook our food, and make sure we don't diseases from raw food and such.

Number 8. Blankets.
Blankets are pieces of fabric that go over top of us, and keeps us warm, helping us sleep better.

Number 9. Clothes.
Clothes are similar to blankets-they keep us warm in the winter, and protect us from getting the flu, and also more serious things like frostbite, and hypothermia.

Number 10. A hot drink, like hot chocolate,or tea.
Hot beverages are used to wake people up in the morning, (like coffee) to trying to fall asleep, (like Chamomile) and they can be very cheering, reviving and relaxing. I mean... who doesn't  like tea?

Anyways... That was basically what we did for our heat menu, and in the next post, I'll basically be summarizing what I learned while doing these experiments and stuff on heat, as well as the impact us humans have on heat.

'Till next time!
