Junior Robocup 2014

A huge congratulations to our seven teams who competed at the regional Robotics competition in Wanganui yesterday.  The teams have worked incredibly hard on their projects and many have spent a lot of their own time on their robots.

A special congratulations to Room 2 students Durann, Jacob, Joe and Caleb who were placed 3rd in their section.  Also to Jackson as his team was highly commended.  I am very proud of you all.  Your commitment and hard work has been extraordinary - and has paid off!

Here are some highlights from yesterday prepared by Mr Webb.

MAD SCIENCE - 27 June

In our Mad Science Elective this week we looked at Coke.  We were testing experiments that we had seen or heard of.  This is what we tried:
1)  Milk in Coke - repeatedly shake and then let out the gas from the bottle - within the hour, the Coke had lost a lot of it's colour and we could see something settled on the bottom.  What was it?  Some thought sugar?
2)  What does Coke do to eggs?  We had three hard-boiled eggs and put one in vinegar, one in Coke and one in water.  Within the hour, the egg in Coke had bubbled on the surface.  What will have happened by Monday?
3)  Mentos in Coke - but not to make it explode, we wanted to turn it to ice.  This was a bit of a fail but we have some ideas to test next week!

A Fantastic Trick for Number Bonds

Today we learnt about a really quick way to calculate Number Bonds of up to 100 000.  Mr Spice showed the teachers on Monday afternoon.  To start with some of us had our doubts about how easy it really was.  But, after a few examples, it all became clear.

An example of a question would be 24 + ___ = 100
What we learnt was that the ones column has to add to 10 e.g. 4 + 6 = 10
The tens column (and anything higher, such as hundreds, has to add to 9 e.g. 2 + 7 = 9

So..24 + 76 = 100

Click on the link below to see our examples.  You do need to download the 'Explain Everything Player' but we're working on an easier way.  Everyone in Room 2 can access all maths lessons in their Google Drive.

Mad Science

On Friday in the Mad Science Elective we made 'fizzing paintings' and experimented with growing our own crystals.

To make fizzing paintings we mixed baking soda into paint and then afterwards, sprayed them with vinegar.

To grow crystals we dissolved as much salt or sugar as we could into hot water.  We have cotton string in the jars for the crystals to (hopefully) form on.

Treats from Hawaii

Room 1 have been collaborating with Ilima Intermediate School in Hawaii.  They had a Skype session and then were sent a package of Hawaiian foods.  Today Mr Chittenden decided that it would be great for the whole school to taste the spreads.  The overall opinion was that they tasted really good.  It's always interesting to step outside our comfort zone and try new foods.
