JMSS 2014 Testing Talk!

[SKGUN11]

Wow thanks! I practically skipped the whole Year 9 maths and yeah now I have to catch up! So yeah I guess I'll need to work on it soon anyway...
Yeah thank you! However, I'm feeling so unmotivated most of the time and I always find excuses like: I don't know what topic to write on or I'm just too busy now to procrastinate :/
Ahh okay thanks! Aww biology stuff? I hate biology...not to mention that the contents in biology is very dry to me...
Ahahaha okay I will thanks!

I gotta strange feeling the science essay (one of them) will be in Physics. Which I am happy in! Haha, I dunno!

hahaha....exactly 

[SKGUN11]

hahaha....exactly 

What topics would you guys like to see for the essays?

I would like Physics - light, force, electricity
Biology - Cells, system (organs and tissues too), plants (anything),
Chemistry - chemical reactions, periodic table, endothermic/exothermic things! haha
There are more...I just cant think right now!

LOL i can tell most of us been studying the same topic!!! haha yea for some reason i prefer physic over chemistry... LOL but then i don't know why but i don't really like studying plants ://

Physics - Motion, Light
Chemistry - Atoms, Matter, Periodic Table
Biology - Cells, Evolution

For me its Chemistry (Easy) > Physics (Interesting) > Biology (Eww, plants)

[waftj]

Guys, just curious would you guys say that Evolution is more likely philosophy instead of Science???
hahaha the reason why i make this assumption is because like there are really any 'Scientific Reasoning/ Evidence' behind it??
LOL so, what do you guys think?? 

[Shinkaze]

So I think we all agree that we do not want Biology to be on the exam....

For me its Chemistry (Easy) > Physics (Interesting) > Biology (Eww, plants)

YAY we're about the same!! Except I probably covered Chemistry more in my school and I actually don't find Chemistry that easy...( a friend tried to explain some molar mass things from Year 11 since last month and until now I still don't get it)
So mine would be something like Chemistry (Covered more in depth) > Physics (Interesting) > Biology (eww, it's biology I don't want to be a doctor)

C'mon, don't be shy guys.

Uhmm I'm never shy. Today I got complained by the teacher for being too loud for oral presentation...

I gotta strange feeling the science essay (one of them) will be in Physics.

Don't mind Physics at all I guess it's alright...not as bad as biology (I actually dislike it)

Well 'Natural Selection' is the scientific way of saying it, and it's generally considered to be correct . I'm mostly writing this as a test of my knowledge, but feel free to read it if you want:

Evolution is a process that occurs through natural selection, and is how a species transforms over time. An example is a moth with a black dot. Thousands of years ago, the species had no dot, and lived in a tropical rainforest where it could camouflage easily. The rainforest had a serious fire a few hundred years later however, and the majority of trees were charred and black. While this happened, there was a genetic mutation in the DNA of this moth, that caused a slight change in one area of the wing, that made it ever so slightly black. Because this moth camouflaged more easily into the black environment than its other variations, it tended to survive more than its counterparts. Because of this, more random mutations occurred, and over time, a black spot formed. The moths with black spots survived for longer than the moths of the same species that didn't, which resulted in it being able to pass on its genes more easily. This is natural selection in action.

Is that correct? ;o

your gonna get into JMSS

[waftj]

your gonna get into JMSS

Totally agree man!!!!!

[Hannibal]

Thanks haha, the example wasn't exactly the best though. I have my money on you folks too .

Well.... isn't that based upon's Charles's Darwin theory on Natural selection. I watched this documentary the other day and I remember that they explained how 'Natural selection' is not based upon evolutionary- meaning that Natural Selection is not an explanation of life.
LOL i dunno man, actually really confused at the moment :/

This is natural selection in action.

Big no at the bolded spots.

You have to remember that genetic variation ALWAYS exists in a population before the selection pressure (in your case, a fire) is applied. Mutations are always random and they don't just only occur at a specific time. The fire does not cause mutations to just appear. Before the fire, there must already be moths with black dots.The selective pressure only "selects" for it and increases its frequency.

If you want, Darwin's Finches are a particularly good example of how natural selection contributes to the formation of different species in different environments.

It's pretty much fact that evolution happened, it is NOT at all philosophy. Much of Biology is focused on our descent from a common ancestor - it can be seen in genetics, cell biology, anatomy, physiology, i.e pretty much everything.

Thanks so much! Really helpful . Need to do some more work on selection pressure, not entirely sure what that is. And sorry I don't think I was overly clear with the mutations, they didn't happen as a result of the fire, they happened randomly.
