Science in a Van
On Tuesday the 22nd of August the senior school were very lucky to have the science in a van visit us and demonstrate some amazing States of Matter Science.

Mentos and Coke
If you haven't tried putting a mentos lolly into a bottle of coke you will know it has an awesome reaction.
We thought we would create a fair test using different types of coke to see if they all had the same reactions.
We tried diet coke, classic coke, and no sugar coke.
We found out that the best reaction happened with the no sugar coke, the geyser created went the highest, the second was the diet coke and lastly was the classic coke.
This reaction happens because of nucleation, where carbon dioxide in the soda is attracted to the mentos creating pressure that the coke goes flying. The mentos have tiny craters on the surface which trap the carbon dioxide till it builds up and then explodes.
We also wanted to find out if the fruit or the mint mentos have a better reaction, and we found that the reaction was the same.

Understanding Viscosity
This week we learnt about viscosity.
It is commonly perceived as "thickness", or resistance to pouring. Viscosity describes a fluid's internal resistance to flow and may be thought of as a measure of fluid friction. Thus, water is "thin", having a low viscosity, while vegetable oil is "thick" having a high viscosity.
We completed two experiments to learn about viscosity:
The first one we look at was race the liquids. We predicted which liquid would be the fastest:
Paint, Dish washing liquid or water.
The paint had the highest viscosity so it didn't move very far at all.
Next, we looked at oil and golden syrup in a bottle:
We then flipped the two bottles at the same time and found that the syrup has the highest viscosity. The results were slightly changed because Miss Prentice left the bottles on the window in the hot sun and the syrup has melted so it moved quicker than it normally would.
Newtonian and Non-Newtonian fluids:
We also learned this week that the concept of viscosity came from Isaac Newton and that fluids that behave in a certain way are called Newtonian fluids, and fluids that don't follow the rules of viscosity are called non-Newtonian fluids. So we made cornflour slime to experiment with non-Newtonian fluids. Did you know that Dr. Suess called this Oobleck.
To make cornflour slime you need:
200 grams of corn flour, 200 ml of water and food colouring (optional).
Mix well and see what happens!
When you hit your slime hard it acts like a solid when you push slowly your hand will sink.

Cross Country
We ran through the cold, wet and sunshine. Through the mud and the hard ground. We ran our best and we didn't give up! Most of us gave it a go even if we don't like running. Some of our super fast runners will be entering the interschool competition!
WELL DONE TO EVERYONE WHO RAN!
GO GILRS!
WELL DONE TO EVERYONE WHO RAN!

Well done boys!

The Ned Show
Today we were very lucky to have the NED show visit us at school.
We had the very entertaining Hayley from California perform with a very important message.
How to be a CHAMPION in life and at school.
N- Never give up
E- Encourage others
D- Do your best.
Not to mention she was a magician and a yo-yo champion!
Yo-yos can be purchased through the school for this week only:
All proceeds go toward the pay it forward program which allows other schools to have the NED show come.
$8 for a Basic Yo-yo
$12 for a bomerang Yo-yo
$20 for a special trick yo-yo
