# Maths Mate Sheet 5 Question 23

READ: Bobby’s car uses 9 litres of fuel per 100km. How many litres of fuel are required to travel from Kogan to Tingura?

Clarify: I had nothing to clarify.

Big Question: How many litres would you need to travel from Kogan to Tingura?

Tool: Write an equation.

Solve: To solve this problem, I started by adding the distances together. 64+122=186+154=340+60=400. I then had to divide it by 100 because it uses 9 litres per 100km. That equalled 4 so I multiplied that by nine and that equalled 36. So my answer was 36.

# 100WC #34

I was stuck in a room, no open windows, only locked doors. It was a pitch black room where I couldn’t escape, well without a key I couldn’t. There were about 10 doors, all in the same hallway, all in a line, nowhere to escape. I was trapped. Just trapped, forever. I was trying to escape when I heard another voice, inside one of the doors.

I was scared too. She wasn’t alone. I replied with an ‘I don’t know’.

I tried to help open the door. I couldn’t.

Goodbye outside world, forever.

# Term 1 Unit Reflection

Our term 1 unit for 2014 was government in Australia. We had to do a timeline of the road to federation. Click here for that post. It was fun to do and we learnt a lot from it.

THREE THINGS I REMEMBER:

1. The federation idea was started by Sir Henry Parkes. He decided to connect all of Australia by telegraphs, but most importantly, FEDERATION!
2. The 1st referendum of pro-federation groups, in 1893, didn’t succeed so there was to be a 2nd referendum.
3. The 2nd referendum did succeddand a constitution was made and was signed by Queen Victoria in 1900.

THREE THINGS I NOW KNOW:

1. I now know that federation was the thing that brought Australia together. Without it, we would’ve been still disconnected and unable to talk to people outside of the state.
2. I also now know that Edmund Barton was Australia’s 1st prime minister and that created the upper and lower house, even parliament just to name some things that were made.

A QUESTION I AM STILL LEFT WITH:

What would happen if there was no parliament in Australia and if telegraphs weren’t created?

# GTAC – Reflection 2

On May the 14th, Chris and Jacinta came from GTAC to teach us about the gas state and all the properties the gas state has.

We did an experiment with a beaker, a cup, a ping pong ball and some water. The beaker had the water in it and we placed the ball inside. We then put the cup over the ball and pushed the cup down to the bottom of the beaker. Do you know what happened? The cup filled with a little bit of water and the ball floated at the top by when we took the cup out, all the gas escaped and there were bubbles.

Some things I remember  are that gas particles are more spread out because there is more space so they can move around and bump off each other as well. I also remember that each particle bumps off the walls because it helps them move around.

I now know that gas particles are in air and air is a gas. Even though I had already known that, I still think it is a good thing to know. I also know that a ball floats in water because there is no liquid inside so it won’t sink and it has air inside.

A ‘what-if’ question I have is what if gas and liquid particles didn’t exist? Wouldn’t we die?

# Tying Beginnings to Endings

In class, we were learning to make our short stories better by tying beginnings to endings. There was a list of story types, intense action, intriguing question, feeling, sensory description and sound effects/onomatopoeia. I chose intense action and here is my story:

Ok, so the story starts in England, on our family vacation. I am Jassena Claren, on holiday with my sister, Veronica and my mum. I am keeping a diary of our holiday.

England, 10:00pm, 18 June, 2012

Rushing around, getting suitcases organized for the flight we were late for. It takes a half hour to get to the airport but the flight is in an hour. We should be at the airport now!

“I am but I’m not sure about Nica,” I said.

“I AM!” Veronica yelled,”Don’t just assume I’m not ready because you are!’

10:30pm

Could Jassena, Veronica and Marissa Claren please come to gate 9 now. Thank-you!”

Gate 9 is now ready for boarding, gate 9 ready for boarding”

Veronica was rushing around, trying to find gate 9 when she didn’t realize she had already passed it. Mum was calling for Veronica to come back, but Veronica, being Veronica, did eventually come back.

10:45pm

We were on the plane, I was ready for the 10  hour flight. I was starting to read while Veronica was listening to her music and mum was trying to sleep and of course, I got the window seat.

Faster, faster and we have lift off. see you in 10 hours America.

America, 8:51pm, 18 June 2012

I have a lot of jet lag from that 10 hour flight and it is still dark outside. I know where I’ll be when I get home.

9:00pm

Back in America, feeling great but before we were out of the airport, another plane had  apparently crashed near by. I saw flames everywhere but we were safe. We got out before the flames spread.

9:46pm

I’m at home finally.

“Jassena, Nica, get to bed!” Mum told us where I wanted to go, bed. Well, I wish I could get over this jet lag before school starts! I’ll try to.

# Education Week – Scientists do AMAZING Things

On the 21st of May, 2014, 5/6B went to GTAC (Gene Technology Access Centre). We went there by bus/tram and we went to GTAC to learn how changing temperature can affect the state of a substance. We left school at about 8:50 to catch the 508 9:00 am bus. We then caught a 19 tram to Melbourne Uni. We were split into groups for after the first session. We also went there because it was Education Week and the theme was ‘Scientists do amazing things’. For our activities, my favourite on was the phosphate test because we got some household items, apparently they were phosphate free. We did some phosphate tests and we proved whoever made them wrong! We learnt a lot at GTAC and here are some of the things I learnt.

If a solid, like dry ice, skips the liquid state, it is called sublimation. Dry ice doesn’t melt so it can’t evaporate but I don’t know why dry ice skips the liquid state. Condensation is a new word we learnt. It means that the droplets outside of a glass with icy cold water in it, the glass draws the hot air to it but cools down the air so it turns into droplets.

I now know that there is a such thing called water fleas, called daphnia and they live in water, dirty water but they can still live in filtered water. I also know how you get the clean drinking water. You get the dirty water and flocculate it. Flocculate is a liquid that sends the dirty stuff in water to the bottom. You then let the dirt settle to the bottom and then filter the water. You chlorinate it and then you have you have the drinking water we have today.

A question I’m left with is: Does the physical change to substances only happen at a certain temperature?  Also, why does dry ice skip the liquid state?

# Maths Mate Term 2 Sheet 3 Question 24

Predict: I predict this question is about filling in the rest of the table using what’s there.

Clarify: There was nothing I needed clarifying.

BIG Question: What numbers complete the table?

Mathematician’s Toolbox: I used have I seen a similar problem?

Solve: I figured out 8×6=48 then I figured out 2×1=2 and 4×3=12 and then filled out the rest of the table. The top row was: 8, 4, 2, the second row: 3, 24, 12, 6, the third row: 6, 48, 24, 12 and the last row: 1,8,4,2.

# GTAC Reflection

On the 6th of May, 2 people from GTAC (Gene Technology Access Centre), Chris and Maria, came in to teach the 5/6s about why solids and liquids behave differently.We did the experiments in the science lab and there are more sessions to come. Chris and Maria came in because our topic for this term is ‘Change’.

We explored why 2 states behave differently by doing small team work activities, by using words of what properties things have as a solid. E.G. play dough: Soft, shapeless, thick, flexible,malleable etc. We learnt a few new words like malleable. Malleable means that something can be shaped or bent etc.

I remember from that lesson that low viscosity means that an element is more runny while high viscosity means it is not very runny e.g. water has low viscosity because it is very runny while honey has high viscosity because it isn’t that runny. In a solid, all the atoms are closely packed together so the object/item can’t be squashed/compressed. The atoms in liquids are loosely compressed so they move around.

I understand that solids are hard to compress because of how their atoms are formed and they’re closely packed together. I also understand why the atoms in liquids join together. The atoms have bonds as in that they join together when they are close to each other.

A question I still have is why are atoms in solids closely packed together when others are less compressed?
