Exploring Simple Machines

We now know that a simple machine is a device that makes work easier by magnifying or changing the direction of a force.

We also know that the six basic simple machines are

- screw
-wheel and axle
-lever
-inclined plane
-wedge
-pulley

We worked in teams with simple machine kits to try and construct 5 of the basic simple machines.
We built the models without any instructions, using only the pictures on the box as a guide.
We demonstrated cooperation by listening to each other, helping each other out and sharing parts when they were needed.
Here are some photos of us at work...







Next, we will explore each simple machine in more detail and explain how they work.

Vowel sounds in te reo Maori

Room 9 have been trying to improve our pronunciation of words in te reo Maori. 
We started by focusing on the vowel sounds and the sounds made by 'ng' and 'wh'.

Here are some videos of us rehearsing these sounds using waiata and chants with actions.

Colour

In Art, we have been learning about colour theory. We have explored the colour wheel, identifying primary colours, then using these to create secondary colours. We discussed cool and warm colours and colours that compliment each other.
Today we explored tint and shade.
 Tint is the mixture of a colour with white, which increases lightness, and shade is the mixture of a colour with black, which reduces lightness or makes it darker.
We chose a base colour and experimented with the tints and shades we could create.









In Writing, we are learning how to enhance our descriptions by writing metaphors.
We chose a colour and then created metaphors to describe that colour.
We used these ideas to write poems.

Here is a slideshow of all our colour poetry.


We have published our poems ourselves on Google docs and are now going to back them onto the shades and tints we created today in Art.
Pop into Room 9 soon to see our completed display๐Ÿ˜„

Friction


We have started to learn about forces and movement as part of our inquiry topic.
Today we explored friction.

Friction is the force that is at work when two surfaces rub together. 
Friction works to slow things down and stop them moving.

We decided to investigate which surfaces create the most friction.
In groups, we discussed how we could test this. We decided on the following experiment design suggested by Ashley, Leroy, Isaac, Jason and Dhruvi;

Using the wooden sphere from our shapes set, we would roll the ball along different surfaces and measure how far it would travel.
After some discussion, we decided to let the ball go on top of a ramp rather than pushing it so we would not affect our measurements by the force we might apply.
We built our ramp out of a tissue box and a hard back book.

The first surface we tested was the table top. The ball rolled for 2m 56 cms. However, it may have kept rolling for longer- we just ran out of table!
 The second surface we tested was paper. The ball rolled for 4 m and 65 cms - Georgia

Next, we tested the carpet. We predicted the ball would move more slowly and stop sooner because it was a rougher surface - Jason

 We observed that the ball went 1m 84 cms on the carpet and it moved more slowly- Raaj
 Then we tested the black matting out on the deck. We predicted it would go slowly because the surface was bumpy and rough- Advika

The ball went 1m 84 cms. This was the same as the carpet- Kenaz
We rolled the ball on the concrete and it went 1m 40 cms before stopping- Leroy

Finally, we tested the astroturf. The ball rolled for 1m and 2cms- Krisha

We found out that the astroturf created the most friction- Vrushti

Everyday examples of friction at work;

To slow things down- more friction
- tread on car tyres (Tanisha)
-roads being made of concrete (Advika)
-concrete paths to stop you slipping (Jack)
- sole of your shoes (Georgia and Caroline)
-carpets indoor so you don't slip when you run (Leroy)

To speed things up - less friction
-racing car tyres without tread (Dylan)
-skis and snowboards are smooth (Jason)
- swimming caps or shaved heads to swim faster (Ashley)

Questions we now have about friction
What would happen if there was no friction? Dhruvi
What would happen if every surface in the world created lots of friction? Caroline
What if racing cars and family cars swapped wheels? Leroy/Ashley
What if racing cars had treads? Kenaz
What would happen if you are stuck in mud and you have racing car tyres on your bike instead of bike tyres? Mujtaba
What would happen if swimming caps were not invented and there were no hairdressers/barbers or hair ties? Caroline
What would happen if skis had grips? Vrushti
What would happen if slides were made of sandpaper? Tanisha/Raaj

John Logie Baird Biographies

Room 9 have been researching famous inventors. We were particularly interested in finding out who invented the TV. We discovered that more than one person was working on inventing the television at the same time. One of those people was a Scottish engineer called John Logie Baird. Although he is not credited with inventing TV as we know it now, he did help to make television possible and we admired his perseverance.
We took notes about his life and journey as as an inventor and used our notes to write biographies. 
We are now working on publishing our biographies by either making a paper based book, creating a Google Doc or orally publishing our work using Puppet Pals.
Here are some of the biographies that have been completed so far;
