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.

So...

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.

Now....

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!

Heat (#3)

In this post I'll be talking about Climate Change, and what we've done for our heat menu.

The goal/purpose to this project was to 'show your understanding of heat in the environment and how it affects humans.'

And like I mentioned in the first post about this topic, we had an Appetizer, Drink, Main Course, and Dessert.

I'll explain it all later.

But right now, I want to get to a pretty important topic-especially when it comes to heat-

Climate Change. 

We've all heard about this term before, but do we care about it?

No, not really. 

Do we know what exactly it is?

No, not really. 

Do we know how it affects us?

No, not really. 

What I'm trying to prove here is that we're always talking about how our cars are causing climate change, how the icebergs are melting, about the rise in sea levels... greenhouse gases... etc, but what exactly are we going on about?

Do we even know what we're talking about? 

We, as humans, think that Climate Change is some foreign, unimportant topic, and that as long as our lives right now are fine, we're going to be okay.

That we aren't going to be affected.

We just don't care enough about it.

Sure, we know about it.

Sure, meteorologists are talking about how we're breaking records for the hottest temperatures all around the world, but we aren't seeing anything.

The proof.

Of course, there's pictures. And we see those pictures, and go, 'Oh they must be feeling so hot right now! I feel so bad.... I feel hot just looking at them!'  

And then we go ahead, turn our backs, go back to living our own lives, and forget all about it.

But it's because we don't feel anything. We live in this place where we are privileged enough to have rain, to have freshwater, to have a decent amount of sun, and to actually have seasons.

Some of us around the world... don't.

But the thing is, we haven't experienced it. We don't know how it feels to faint of dehydration, to want water when there is none left, to be left on the blistering hot sand, with no shoes, no hat, no shade-nothing to protect us from the sweltering heat of the sun.

We think nothing has changed from the last 100 years, so we ignore it.

But as Philip Watts once said,

'Ignorance is not bliss-it is oblivion.'

And it's true.

By ignoring these problems, we are causing even bigger, global problems, which is going to affect us all.

But all this talk isn't going to describe what Climate Change is, and what's happening to the Earth.

When the sun's rays reach the Earth's surfaces, some are absorbed and remitted as heat. Greenhouse gases, such as water vapor, and carbon dioxide, absorb and re-radiate as as heat. In creased amounts of greenhouse gases in the atmosphere means more heat is trapped in the atmosphere, which warms the Earth.

Human activity, such as the burning of Fossil Fuels, are increasing, as the human population also increases. Over the last century, (mainly since the 1900's) amounts of atmospheric carbon dioxide have increased over 40%.

Global average surface temperature has been raised by about 0.8 Celsius, over that time.

Ocean heat, the ocean sea level, have all increased and much of the snow and ice in the Northern Hemisphere has decreased a lot as well. The melting of sea ice in Arctic has, and will cause lots and lots of problems, including the rise of sea levels, especially places by the sea, like P.E.I., and Florida, and small islands, like Hawaii, the Philippines, etc.

If this continues to happen, then by the end of the century, the Earth's average surface temperature will have been raised by about 2.6 degrees Celsius, to 4.8 degrees Celsius, but even 2.6 degrees will have serious implications, and cause many changes.

But Climate change doesn't affect just humans. It's not just a global problem. In fact, it can affect even the smallest things, like snowshoe hares.

These hares molt during the spring and fall, which means that they're brown during the summer months, and white during the winter months. Snowshoe hares always molt around the same time. Of course, it sometimes changes, especially because they respond to light, when the days get longer or shorter. But that means that the weather has to cooperate as well.

But it's not always that the snow comes around the same time. (as the days start to get shorter) So if the snow comes later than usual, you've got a white hare against the muddy, brown-grey background.

If the snow melts, due to climate change, (even if the days aren't getting longer) that means we'll have a white hare against the darker background.

But these aren't things that happen once in a blue moon-they happen every.

Single.

Year.

Of course, these hares can hide, but the problem is, they themselves think that they blend in. We, as humans don't understand how that happens. Humans immediately know when we don't fit in, or when we don't blend in with the crowd. These poor animals don't know that they don't blend in.

So animals like the Canadian lynx, foxes, raptors, and even red squirrels, will take the chance to eat, and will hunt them.

They become prey.

Obviously, it's not that  big of a deal... right?

I mean, it's just one animal.

Wrong.

If  by any chance these animals die off and become extinct, that's one less animal in the food chain, one less animal to feed off of... it affects everything. If it was just this one animal, that may not be that much of a big deal.

But animals are dying all over the world, just because of what WE are doing. We are the ones cutting down rainforests, sending every animal, insect and arachnid, fleeing into other places, disrupting another food chain,

We are the ones killing bees with pesticide,

We are the ones killing polar bears, turtles, whales...

The list goes on, naming many different animals, like penguins, and cod.

All these animals are so, so very important to this Earth, but what are we doing?

We're destroying what we were given, throwing their lives away, as if they are of no importance to us.

But they are.

And soon, we're going to meet the same fate.

I advise you to start to actually CARE about this Earth, or we will all go down into oblivion-which I don't think anyone would want, considering how far we've come.


-Thanks for reading-considering how long this is!

Heat (#2)

So... this is a continuation of the previous post-which was basically a summary of what we did. In this post, I'll be talking (well... writing actually... but who cares... right?) about the first part of the Heat unit and what we did.

It was in... March (I believe) that we first started talking about temperature and heat, with Mrs Malcolm. Then, we moved to talking about the difference between Heat and temperature, and we learned about the third type of temperature measurement, Kelvin. So we learned how to get these temperatures, (like, the equations) and here's a list:

HOW TO GET:
Celsius-Fahrenheit: °C  x  9/5 + 32 = °F

Fahrenheit-Celsius: (°F  -  32)  x  5/9 = °C

Celsius-Kelvin: °K = °C + 273.15.

Kelvin-Celsius: °C = °K - 273.15

Fahrenheit-Kelvin: °F  -  32   x   5/9  +  273.15

Kelvin-Fahrenheit: °F  =   1.8  x  (°K  -  273)  +  32

*  *  *  *  *

That was that.

Next, we moved onto Particle theory, which is well... like it's namesake-a theory about particles. Listed below are the five MAIN points of Particle theory.
- All matter is made of tiny particles
- Particles are always moving
- The spaces between the particles are large compared to the the particles themselves
- The particles are moving faster when hot and slower when cold
- There are attracting forces among particles. The forces are stronger when closer together.

Based on this, we did an experiment where we had two different beakers, one filled with hot water, and the other filled with cold water and we had to put ONE DROP of dye in each beaker, and draw what it looked like, (as the dye was spreading) time how fast it spread fully into the beaker (so, basically changing the color of the water entirely) as well as justify why and how the dye had spread faster in either hot or cold water.

There are experiments that I can't really think of off the top of my head right now...

But I do remember Lesson #7, the last one... I think... and that was where we had to put in 4 different types of spoons in a kettle with hot water, for about a minute each. When we pulled it out, and it was not cold, it would be a bad thermal conductor, but on the other hand, if it was hot, then it would be a very good thermal conductor. We then had to (once again) justify why a certain spoon was a better thermal conductor than another spoon, as well as explain why it would be important to know which material makes a good thermal conductor.

Well... that's it for now... sorry it's so long. I'll be talking more about Climate Change and out heat menu in the following post... I think..

Thanks for reading!

Heat (#1)

Hey guys!
So... okay, first off, I'm really sorry I haven't been posting anything... it's been a while.... like, a long while.

ANYWAYS... I'll get to the point-and as the title says, HEAT. For the past couple months, our class has been doing science experiments, on the subject of heat. We've done things like the Particle Theory of Matter, the difference between HEAT and TEMPERATURE, as well as the three different types of temperature-Celsius, Fahrenheit, and Kelvin. As well as classifying things into conduction, convection and radiation, the different states of matter-just to name a few.

We've also been talking about how climate change affects all of us, animals and insects included. I think it's important to remember that what we do as humans, (like burning toxic waste, etc...) affects EVERYONE and EVERYTHING living on this planet. We often take things for granted, acting selfishly, and forget the fact that what we do now, affects other people around the world, as well as future generations; like our kids, and their kids....

All this has been incorporated into one MASSIVE and GIANT project-our heat menu.

Carson and I (a/n: Or is it me and Carson...??? I'll never figure out the proper way to say that sentence.... haha.... could someone correct me in the comments section below as to which one is the correct way of saying... 'Carson and I' ?) have been working together to make this 'Heat Menu' which basically is doing an experiment, and writing down conclusions (Appetizer), read an article about how heat affects... us (Drink), do an experiment outside, with the thermometers, (Main Course), and finally, make a final 'presentation' (which could be anything, really) as to show what we have learned about heat, and how it affects us.

This just sums up what we have been doing-but I will explain everything in more detail in the next few blog posts!!!!

Stay tuned for more!

Poetry

The beach

While running on the sand,                           I feel,
my feet sink in.                                              Joy.
I stop.                                                            Wonder.

At the edge,                                                  Happiness
and I spread my arms out,                            Laughing,  
closing my eyes,                                            I go.
breathing in.                                                  My feet sink in,
while running on the sand
The smell.                                                   
The taste.
The sound.

I listen.
Waves,
seagulls,
wind…

Me.

Inhaling,
I let myself enjoy this moment,
the moment I have alone,
with just the world,
and me.

The wind breezes by me,
and sprays of cold, salty water
wet my billowing clothes.

I am the only one left.

The last human.

There is only me,
and Mother Nature left,
dwelling on this Earth.

Strangely, I feel…
Free.

Free of all those judging eyes,
those whispers,
those pictures, and comments.

Smiling,
I open my eyes.

Slowly,
and the first thing I see;
the sun,
the sky.

A rainbow.
All the colours.
Blended together,

A piece of art.

Me. 
Pain.
Don't feel it. 

I'm numb. 

Empty. 

Hollow.                                                    
                                                                          
I finger the bruises
on my body.

So many,
on my imperfect body.

Each one...
a scar,
a wound.

If I died,
would they care?

Am I that worthless?
Am I a waste of space?

Of money?
Of time?

No one would care.

I am worthless.
A waste of space.

Of money.
Of time.

A waste.

That's who I am.
What I am.

I glance at my mirror,
at my reflection.

My large, discoloured, and Imperfect body. 

My gross, bloated, and inflated body. 

Me. 

In the mirror, I see my bed. 
Under the bed,
the monster.

'All the monsters hide under the bed,' 
they say.

It's true.


My poems.... sorry they're so late! But here they are! Comment what you think of them!
