Rockvan


Rockvan came to our school this term...what a great week we had learning to play bass, electric guitars and drums...all culminating in a rock concert on Friday afternoon. These are some of our comments about the incredible week we had.


The thing that I enjoyed was learning the drums and performing song "I Fought the Law" by The Clash to the school. AWESOME!!!
RD

Rockvan was the thing I enjoyed most this term I played the drums for the first time it was really cool to experience this type of instrument not just percussion.
HW

Rockvan was so cool because I got to play the drums. The drums had so many cool sound that I could play with.BB

Rockvan was awesome because we got to have a concert at the end of the week and we performed our song to the whole school.AM



I really enjoyed lerning the bass guitar because it wasn't to hard to learn because there were only 4 strings. I was really nervous that I would muck up on stage...... but I didn't!!!! GF

I loved playing the drums at the concert it was rocking the world!!!!!They had lots of cool sounds that I loved to play!!!42 I think?M.L

The base was fun to play because I have never had the chance to play the base guitar in my life and i'm definatly going to get a base guitar!!!T.N

I really enjoyed rockvan because they helped us learn a instrument and on Friday we got to peform a concert to the other pods which was AWESOME!!! I really liked playing the base guitar aswell because it was easy to learn and only had 4 strings.
E.P !!!

I realy enjoyed playing the bass guitar because I have never played the bass guitar before .I also enjoyed you guys teaching me how to play the bass guitar I would like to play the bass guitar agin .J.p

I really liked RockVan because it was a great opportunity to try a new instrument I had never even touched let alone played before. The drums were really fun and it was cool that they had different settings! I found the guitar and bass really easy ad fun and the teachers were awswome!B.M

Rockvan was a great oppertunity for kids as we got to play instruments we don't usually get to play at school. Playing the electric guitar was an exciting experience that I will never forget!!!!!!:NM

I really enjoyed Rockvan because I always wanted to learn the drums and they gave me the opportunity to. I also really enjoyed the concert!! C.S

Clocks and time

Our topic for this third term has been CLOCKS.
As a class we looked at how clocks developed from the early sandclocks, sundials and candle clocks to the precise clock mechanisms we have today.The highlight of this unit was to spend a day building our own clocks according to the designs we had researched and planned beforehand.
We encountered many difficulties on this day from dust sticking to our wet paint, to not getting the numbers even and to realising just how hard it is to paint thin lines with a wobbly hand.
Many of the clocks were made for our dads as gifts for Fathers Day and I'm sure they would have been delighted with their personalised clocks and will treasure them for many years to come.
Have a look at how our clocks turned out!

Science Electives

We're fortunate at our school to run electives one afternoon a week for the whole of Term 3. One of the electives on offer is science experiments.
For our first session we looked at surface tension and related experiments. Check out this great experiment from Brainiac via You Tube!




During this lesson we made our own "Non Newtonian liquid" using cornstarch and water. It was amazing because when we hit it quickly it was rock hard and yet it also became runny enough to slide off our hands, as these pictures show!










MILK SWIRLS and SURFACE TENSION
We also had a heap of fun making milk swirls when we took a saucerful of milk, added a couple of drops of different food colourings and then a drop of dishwashing detergent to the centre of the milk. Wow we made some fantastic patterns and had great fun seeing if we could get the swirling to continue by adding more dishwashing liquid, more milk or more "anything"!




Can you believe it, we're also MUMMIFYING SAUSAGES! Yes, that's right, we are dessicating(drying out)a variety of sausages with bicarbonate of soda; a bit like the Ancient Egyptians did when they mummified their Pharoahs.
Each week we recoat out sausages in fresh bicarbonate of soda because we have found that the bicarb. becomes quite saturated and encrusted from the fluid it is drawing out of the sausage. We also measure the weight, length and circumference of the sausages to see if there are any differences from week to week.
Follow this table to see what the results show on RD,O and SL'ssausage:

Pre mummification
Weight: 0.1g
Length: 6cm
Circumference: 8.5cm
Features:Colour Red
Smell:chicken but not roasted
Teacher’s/student’s comments: RD: I can't believe we actually get to do this. Can we put the insides in a sarcophagus too? Mrs H: NO!

1 week later
Weight:0.1g
Length: 6cm
Circumference: 6cm
Colour:Dark red
Smell: mouldy dead rat
Teacher’s/student’s comments: Not sure about the accuracy of your circumference measurements, boys...we’ll have to check them this week! (Mrs H)

Have you ever tried making icecream using ice, salt and plastic packets?
We did last week.
Into one small packet we placed 1/2 cup of milk, chocolate/peppermint or strawberry essence, a spoonful of sugar...and zipped it closed.
This small packet we placed inside a larger packet with a couple of cups of ice and about 6 spoonfuls of salt. We ziplocked this one closed as well and then started squeezing the milk against the ice.
Some of us squeezed a little too enthusiastically and our bags popped (luckily we were doing this outside!) but those who persisted squeezing GENTLY ended up with some delicious icecream.
One packet of ice contained no salt and that one never became ice cream...it remained milk. Why was this do you think? We know..but we'd like to hear your comments! (A clue...it has to do with the effect salt has on the melting point of ice)
So, with very cold fingers and full tummies, we think we could make quite a lot of money from our new found knowledge!



Static Electricity
Have you ever bounced on a trampoline and touched a friend, only to have them shock you?
We explored this shocking effect by looking at the flow of charge from a positively charged body to a negatively charged body. At first we tried using our socks to charge the balloon but as this wasn't particularily successful at giving a big enough charge, we caught onto the idea that by rubbing the balloon on our own hair, we could create a bigger charge.
Using the positively charged balloon we then lowered it over a dish of pepper and made the pepper dance by being attracted to the balloon. When we were quiet enough we could even hear the crackle of the pepper as it was attracted upwards onto the balloon's surface. Of course, if the balloon touched the sides of the dish, it was discharged and would no longer attract the pepper upwards.

creme the egg marble run

In the middle of Term 2 a few boys in our class were very keen to build a marble run. This has been one of those of projects that has gone from strength to strength and is by no means completed yet. We now have a full wall of marble tracks in our classroom and by the end of Term 2 our track had gone aerial! One of the clips that has amazed us has been this one from You Tube. Watch this space for videos of our own track during the course of Term 3!

Digital stories

As part of our English unit, we looked at writing explanations.
Yes, we practiced with some of the more ordinary topics, but then looked at the explanations written in the Dr Xargle's Books of Earth Relations by Tony Ross. This added a whole new dimension to our explanations as we could make up words for some of the things humans use and we could step back and see our earthly habits from an alien perspective!
Enjoy our stories with us!

Room 18's system prints

We had a lot of fun designing these prints. As we were studying systems we looked at robotic systems as a set of related parts that worked together.

After designing our systems, we spent many hours cutting out different textured materials and building up the layers by glueing them onto cardboard backing. It was then time to choose a colour, ink the print, turn it over and then, with heart in mouth, peel it back to see what we had created!
