Rainbow in a glass

Last term we did kitchen science and I am going to tell you about an experience called rainbow in a glass. It was part of us exploring and learning about density in liquids and was part of our Kitchen Science topic.

First we put water in the three beakers. We had a fourth and it was used for a different process. Then we put a drop of different food colouring in each of the beakers. The colours were red, blue and green. Next we put the sugar in. We put three teaspoons in the green two in the red and one in the blue. We put this amount of sugar in the different beakers of water so that they could stack as layers without blending into each other.

Then we stirred the sugar into the water and it took about five minutes to disappear as we had to dissolve it completely. We had made a solution. After that  we poured the green water into an empty beaker. We poured it over a spoon, gently trickling it down. We poured in the solution with the most sugar first and add the other two with less sugar after that.The reason we put it first is because it had the most sugar which also led to the most density. We poured the red coloring water on top of the green water. After  that we poured  the red colored water in. We poured the blue colour water on top of the red color. It clashed a little bit but steadied in a second. The rainbow is complete! It was a very fragile rainbow so a slight bump could wreck it. That was the complete phrase of a rainbow in a glass.

Each layer sat on top of the layer which had more sugar than it had.

Lots of rainbows!!

Lanterns for Matarki

lanterns

Last term room 11 made some lanterns.

First, we cut out four bits of cardboard.

Then cut a window inside the cardboard.

After we drew a design.

I drew a star.

Then we stuck our design on the card board.

Next we hole punched about 8 holes on each long side.

After that we threaded string through the holes.

We made a bottom for an electric candle.

Afterwards we made a handle with ribbon.

Finally we put a candle inside.

Cross Country Run

cross country

Last Wednesday afternoon the senior school went down to the Monk’s farm near the school for the x country.

The yr5 girls went first then the yr5 boys and so on. When the yr8’s went for their run Mr Forsyth encouraged them with some cow dung to try and hurry them up, but it didn’t work. The yr8’s had to run the same track as us because the farmer had left all his bulls in the paddock that they were meant to run in.

To get into the Central finals we had to make it into the top six.If you did make it into the finals you would still have to run the same track.

It was really fun going to the cross country and I hope if you try to run that cross country you will have a good time too!

Tahitian visitors

dance

Last  term the Tahitians sung and danced to some of the school. They did some really cool dancing. They sung a few songs, one was quite emotional for them, they practised it for two years for the day. Then the girls did a dance, it was a cultural dance. After the boys did a very different dance, it was lots of different songs mixed together the dance was funny because one part in it was when two boys did a ball dance together. The Tahitians did things like sport and other things with the year six. The kapa haka did the haka and asked the Tahitian boys to come up as well. I liked the Tahitians coming because they were all really nice.

HERE IS A PIC OF THE TAHItIANS DANCING

Sundial pavers

Warning!:

Please wear a paint shirt, a breathing mask and some glasses in this experiment

Pavers

Today Mr Forsyth taught us how to make cement pavers, the reason we’re making cement pavers is because they’re for our sundial that we’re making. We’re also putting clay tiles inside the cement block, but we’re not going to talk about that now.

Firstly, I’m going to tell you how to make white cement. The reason we’re making white cement is that it looks more decorative. You have to grab all the materials, a screwdriver, a hammer, gravel, a bucket, smooth white sand, sunflower oil, coloured glass (You’re only allowed 3 colours), white cement powder, a mould* to put it in, a trowel* and water.

We put the oil around the inside of the mould so the cement won’t stick to the mould. Then we put the coloured glass in the bottom of the mould. Then we put 3 litres of smooth white sand, 1 litre of black gravel, 1 litre of white cement powder and 1 and a half litres of water in the bucket and mix it all together. Next you have to scoop the mixture out with the trowel and place it in the mould not fully to the top. Then tap around the edges lightly to get rid of the air bubbles. We fill the rest of the mould up with some grey cement so then you don’t run out of white cement. Tap around the edges again. Finally smooth the mixture with the trowel.

Leave it somewhere not too hot and not too cold for about 30 hours and then after that, it will be hard as rock. To get the cement out of the mould you use the screwdriver and unscrew all the screws. Sometimes you have to use the hammer to separate the wood from the cement. Done.

*Mould* A mould is a wooden box with a hole in it where you put the clay block in.

*Trowel* A trowel is a piece of metal that you use to smooth wet stuff with.

Lanterns for Matariki

For the last couple of weeks of Term two and three Room 11 were making some lanterns to celebrate Matariki.

This is how we made them ….........

Firstly we got 4 pieces of cardboard and got our ruler and a black marker and ruled four lines down the side of the cardboard. Then we got a craft knife and carefully cut along the lines in marker.

Next we got two pieces of A4 paper and drew a picture on it that has something to do with matariki. Then we very carefully glued them onto the piece of cardboard.

Then we got a hole punch and punched several holes along the side of the cardboard. Next we got some ribbon and started to thread it into the holes when we had finished we had a box shape. After we made a bottom bit out of cardboard then we had to glue gun it to bottom of the lantern and then we had to make a circular piece of cardboard and stuck it onto top of the bottom piece. After if we wanted to we could buy a electric candle from Mr Forsyth to put in the bottom of our lantern..
