JMSS 2014 Testing Talk!

[Elisha913]

I'm not exactly sure where I saw this, but your parents (or whoever's email you put in when you applied for the tests) will get an email around Wednesday or something giving you all the details about the testing (like what you need to bring, times, etc.)

cool thanks!! good luck

Hahaha other way around SKGUN, Endothermic is when energy is taken in from the surroundings
Exothermic is when heat is transferred from the surroundings
Dw man, i thought u were correct, until i check my notes... hahahaha
I am freaken worried, because i don't know how hard the test will be or how smart are my competitors!!

hahaha thanks! Ikr? Hopefully all of us perform rlly well.

Wow the exam starts so damn early 
I really hope I get to sleep in time the night before without nerves not letting me sleep.

1 What is Transpiration?
2 How is water from roots carried to the leaves?
3 Where is excess water stored in the plant cells?
4 Why is it that hot air rises up?
5 In nuclear reactions, are atoms or matter lost, gained or changed?

1 What is Transpiration?
2 How is water from roots carried to the leaves?

Well, the first two questions go hand in hand.
1. Transpiration is the process of carrying the water through a plant.
2. It's carried from the roots to the leaves because of a tissue called xylem (is that how you spell it?). Xylem carries the water and nutrients up to the leaves of the tree. When water is evaporated from the leaves, negative pressure is created which pulls the water up through the tree. If this didn't happen, the water wouldn't be able to get further than 10 feet (something like that) due to a combination of air pressure change and elevation change, as well as gravity pulling the weight of the water down.

Is this right? I'm pretty sure I once read something about this in a new scientist magazine.

#4 Hot air rises up due to the process of convention. Once a fluid is heated, it expands and becomes less dense, thus it rises towards the atmosphere. Cooler fluid are more dense and thus they sink towards the ground.

yeah haha! Transpiration is when water is evaporated from the surface of the leaves. The xylem tissue carry H20 up the plant and as it is evaporated from the top, it continues to move up.

yep, well done!

Does anyone know if in JMSS there are before or after school activities

Does anyone know if in JMSS there are before or after school activities

Every Wednesday afternoon they run a range of co-curricular activities which you're able to choose from. They have a variety of activities including language, music, arts, health and other things like chess and debating too.

There's some more info about it here: http://www.jmss.vic.edu.au/jmss/2576/co-curricular-options?frm_id=25

thanks, any before school?

I'm not actually sure about anything before school. It might say something on the website

Oh, and nice dog

Ok this is kinda off topic but did you guy know that there are 3206 people going for MHS macrob nossal and Corey... That's huge!!!!! How many people do you reckon will be at ours next week.. There weren't that many people at the information night and there weren't many people on my tour and most were year 10 going for year 11

Well, last year there were around 1200 people or so. My prediction is that there will probably be around 1000 - 1500 people, but it could be much higher or lower. I'm not completely sure though.

EDIT: Turns out there were around 800 people... much less than I expected

Only 7 sleeps to go :O

How are you guys keeping up with all your study?

My progress so far:
Maths: Mostly Confident.
Numerical Reasoning: Confident.
Science Reasoning: Pretty Confident.
Science Interest: Depends on topic...
Science Communication: Working on it.
