Coke Explosion! Science Experiment Recount by Brittany G

I was sitting in the garden., waiting for my sisters to come and bring the coke out, and my brother to bring the mentos to the garden as well.

I jumped off the ground and waited for them to come through.

Then..A figure emerged behind the gate, clicking sounds from the lock being un-hooked.When the lock was un-latched, my sister and brother came walking through.My eldest sister, Hilary, cracked open the bottle of coke, setting it down onto the grass.Then, Ethan, my second eldest brother had opened up the pack of mentos.

I jumped up and down enthusiastically, my brother hands me the mentos, I held one in my hand.I shouted at them to stand away and they slowly walked backward, away from the bottle.Quickly, I had thrown the mentos inside the bottle, the reaction was taking place already.

I had figured out that in my case, the reaction was called Nucleation, in which the carbon-dioxide inside the coca cola or in all fizzy drinks are attracted to mentos, It creates too much pressure within the bottle, so because of gravitational force and physics,  the soda goes shooting upward and rockets into the sky.

After, I ran away hurriedly, behind me the carbon dioxide slowly bubbled upward.Foam bubbled from the top of the bottle, it shot up quickly straight up into the sky.

I just sat and watched in awe while watching the drink slowly fall to the ground in splats.

I had loved the day and it seemed that there was to be more in store for me.

Mad Science

It was around midday, me and my friend Dylan or also known as Dk Plays YT (go and subscribe to his channel). We were sitting on the mat with the rest of the hub waiting for our teacher. I was reading the Science experiments up on the board. The first one was the fizz inflator, the next one was Dancing raisins "I wonder what that is", I thought. The last on was the Supa Dupa Lupa!!!!! I was most looking forward to was the fizz inflator. Finally the teachers came and instructed us to go to certain places in the hub. We went to the lino first to do the fizz inflator.

We all found a seat and opened our chromebooks and looked for the heading Fizz Inflator In a doc. Dylan said I would take notes and he would write down the ingredients, hypothesis and instructions. Mrs parker (our favorite teacher) started explaining chemistry formulas or symbols, H2O and lots of other symbols. She explained how yeast needs sugar to feed on.

Once she'd explained everything she showed us the first experiment. First she added a bit of water and sugar. Then She poured in a spoonful of yeast. She quickly put a balloon over the top of the bottle. We were surprised It didn't explode. Dylan immediately put his hand up and asked why it didn't explode. Mrs parker said "It didn't do anything because the yeast needs time to eat the sugar so eventually the balloon will blow up", Mrs Parker explained. "The balloon should be pretty big at lunch", She said.

Now it was time for the next experiment. This one Mrs Parker had another bottle. She filled it with vinegar. She grabbed up the balloon and filled it with baking soda. This time we were really wondering how this would react. We both had experience with volcanos when we were in kindergarten so we had a bad feeling about this. She tightened the balloon onto the top of the bottle. Then she suddenly tipped it so the baking soda fell into the vinegar. Mrs Parker was holding on to the balloon very tight so it didn't fly off. Amazingly the balloon started to blow itself up. It started to fizz up like a fizzy drink after it had been shaken.

We wondered why. Mrs Parker started to explain how the baking soda reacted when it was poured into the vinegar. Finally it was time to go onto the next experiment. It sounded really cool. It was called Dancing raisins. Dylan and I walked excitedly over to where that experiment would be performed. Mr Stuart explained the instructions even though we had already read it. We wondered what would happen. We were using soda water, raisins and a transparent plastic cup. We got on with the experiment.

We got some soda water from mr stuart and went off to our table. We made predictions on what was going to happen. "I think the raisins will jump out of the cup", I said. We kept on talking. Finally Mr Stuart came round with some raisins. We grabbed 5 or 6 each and threw them in the cup. It got a bit fizzy, but luckily it didn't spill.The raisins had air bubbles all over them. Then suddenly 3 of them floated up to the top, they stayed there for 15 seconds then floated back down. It happened about 5 times over 1 minute and 30 seconds. Mr Stuart came round and gave our cup a flick. He said it might make some more float up, but they only floated back down. The raisins weren't floating up as much now.

Dylan and I were typing down notes rapidly. We didn't know why were floating yet. It was time to go down to the mat so Mr Stuart could explain why the raisins reacted like that. I think it was because when the raisins get tipped into the water they float to the bottom, then all the bubbles in the cup cling onto the raisins. The bubbles lift the raisin up to the top. The raisin floats up. The bubbles keep it up for a bit then pop. The gives the raisin back its weight and floats back down to the bottom. Now it was time to go onto the next experiment. We walked to the next experiment, our heads bulging with knowledge.

This was Whaea Nins experiment. It was the amazing hoop glider. Whaea Nin explained what to do. She explained how the physics worked. Finally we got started. She roughly cut us 1 big piece of paper. We had a choice of hot glue or tape. I chose tape. I thought it was the easiest. I made a circle. Then we did the same thing except smaller. We put a straw through then threw it. It flew really well. Then we tidied up.

This was an awesome school day. I learnt loads. My favorite thing was the fizz inflator. I was really suprised it didn't explode and I wondered if You could put much more in and make an explosion.

Jensen's recount of Science Week Activities

On Tuesday 17th of may 2016  my class hub 8 had Science Week

My favourite thing that we did in my class was the dancing raisins. They were very cool.

First,   Mr Stuart told us what we needed was sparkling water and some raisins.  It was not much but it was what we needed for the experiment to work . so, after about seven minutes the raisins  had started to go up and down so it cida looked like they were dancing it was super funny. Mr stuart told us that what happens with the raisins is they collet air in the soda and then when they go to the surface then they lose their air and go back to the bottom and this happens a lot after a while. At the end i learned a new experiment that was super awesome and super funny. Science week was amazingly cool.

That was the plan and this is the real recount.

Dancing Raisins

On the 17th of May 2016, Hub 8 were doing science experiments because it was science week. We did this experiment called dancing raisins with Mr Stuart. I was very curious on finding out what will happen at the dancing raisins experiment.  

For that experiment we needed: soda/lemonade, a transparent cup and 6 or 7 raisins. We used soda. All of us got into groups of two or three so we could share a cup. I was in a group of two with Vera.

First, Mr Stuart poured the cup full with soda water and Vera and I watched the cup as the bubbles from the soda fizzed up immediately. Then Mr Stuart gave us about 6 raisins, Vera and I split the raisins evenly between ourselves so Vera dropped 3 raisins in the cup and I put 3 in too.

Then we kept on watching the raisins that were in the cup. The raisins did not move that much, it was still sinking in the bottom of the cup. After a few minutes, some raisins raised to the top of the cup then sank back to the bottom again.

Mr Stuart came to us again and explained to us why the raisins were raising to the top of the cup, he told us that the bubbles from the soda were sticking to the raisins and pulling it up but then the bubbles reacted and popped so the raisins sink back down. Then he suggested that maybe this experiment would work better if we used lemonade instead of soda.

I really enjoyed the dancing raisins science experiment because I learned heaps of knowledge. I found the experiment very exciting because I never thought that the bubbles from the soda would stick on the raisins and then pull it up. That is how we did the dancing raisins experiment.

The Dancing Raisins

On the 17th of may 2016 hub 8 learners decided to try some science experiments because it was SCIENCE WEEK! I was so excited to try out the science experiments that was planned for us. One of the experiments was called the Dancing raisins it sounded really cool and fun.

The ingredients for this experiment was really simple and I could even do it at home, it was only lemonade or soda water and some raisins, with a cup. I wondered how it would make the raisins dance? The ingredients made me really curious about this experiment.

Before the experiment, we predicted that the raisins will dance and float above the water. I predicted this because I know that soda is fizzy and maybe the fizz would make the raisins float and dance in the water, and because of it's name ( Dancing raisins ).

The first thing I did was pouring the soda/lemonade into the cup and add some raisins. When I put the ingredients into the cup, I was asking myself if the raisins would even dance? What actually made the raisins move?

I had a lot of questions bursting into my mind, I really wanted to know answers for all of my questions. Maybe it was just me but I thought that it was sure kind of boring when you had to sit their and watch the raisins, It was really weird because the raisins weren't moving they were just lying on the bottom of the cup, I started wondering if we did something wrong or if the name was called wrong? Just then when we were going to give up hope some of the raisins floated up onto the water and then went back down, as if it was dancing!

I was really confused of how the raisins floated up but then went straight down again? We continued on looking at the cup of dancing raisins and we saw that bubbles were starting to form and stick onto the raisins maybe the bubbles were what the things that make the raisins float, but then why does the raisins drop down once they floated to the top? Mr Stuart told us that the reason why the raisins will drop down is because once the bubbles reach the top they will automatically pop and then the raisin will have to much weight to float and drop down. But their was one question that everyone had how did the bubbles even stick onto the raisins? Nobody had the answer for that one.

I learned that the raisins were to heavy to float but the soda's bubble are light enough to make the raisins float up. From my estimate I learned that there's lot of learning behind a science experiment. I also had a lot of fun doing this experiment.  I would definitely do this experiment again!

The Dancing Raisins by Cooper

On the 17th of May 2016 the Whole of Hub 8 did a science literacy day.

The first thing Mrs Parker literacy group did was all walk over quietly to Mr Stuart's area. We all sat down and listened to what we would be doing and how it works. Mr Stuart told us why the raisins would go up and down. He told us that the raisins go up and down because the bubble hold onto the wrinkles lift it up to the top and the bubble pops so then the raisin goes back down. Then Mr stuart explained to us what ingredients we would be needing. You need Soda Water, 7 raisins and a cup to put the ingredients in.

Mr Stuart then told us to get into our groups of 3. The group I was in with was Charlotte, Georgia and myself. We walked over to our table and sat down. Then Charlotte had a idea to make a video about. As soon as Mr Stuart came with the ingredients we needed to do this experiment we turned the camera on and started the video. I poured the soda in the cup and Georgia put in the seven raisins. Then Charlotte told the video what we were going to be doing.

When we put the raisins in the bubbles started to stick to the raasin and start to lift it to the top. We watched the bubbles go to the top and popping and dropping it. We each wrote down what we were seeing. The longer the raisins were in the cup the colors would change and the raisins looked like they getting even more wrinkly. We each took turns showing the camera what was happening in the cup and it was my turn. I picked the cup up and after a couple of minutes no one else wanted to hold it so I was stuck holding it. When I didn't know it all of a sudden I dropped the cup. When I dropped I quickly ran to get the paper towels and quickly wiped the table. When I was finished cleaning the mess up, Me and Charlotte quickly on the computer to see if the video but it wasn't. We were really disappointed but we were fine.

That was one of the coolest experiments ever. It was cool learning about why and how the raisins were going to float. It was funny how I dropped the cup. I had a really fun time.

Pativai's Awesome Science Week

On the 17th of may in hub 8, all of hub 8 did science experiments cause of science week. We all rotated around going with our reading teachers first, then going on to the next experiment. We got to do three different experiments that I couldn't wait to do.

I went with Miss Parker first my literacy teacher and we did a fun experiment called the fizz inflator. First Miss Parker showed us what some of the ingredients were if you were doing biology for example, h2o was water and carbon dioxide was gas.

For our first fizz inflator bottle we put yeast h2o and sugar and we did that in a different bottle. We put an balloon on top to see if it was inflating to make the balloon go up. Miss Parker told us that we put the sugar in because the yeast needs to eat on something.

In the other bottle we put baking soda in the balloon we put vinegar in the bottle, then we put the balloon on and it reacted so quickly. I got to see the balloon fill up with air so quickly. I was wondering if you put in another ingredient would it still fizz up.

I thought that the way that it fizzed up was because of the ingredients inside of the baking soda and the vinegar then the, baking soda and vinegar combined it can cause a fizz and since we put an balloon on top trapping it, inside it filled the balloon.

I went to my second rotation this one was with  Mr Stuart he was doing dancing raisins. We first sat down and did a prediction before we got to the real experiment. My prediction was that the bubbles from the soda water would have some kind of reaction to the raisins. Since raisins are a solid and soda water is liquid it could do something to make the raisins float and sink.

I did my experiment with Faith and Shanya. We poured some soda water in the cup the we popped some raisins in. First the raisins floated then they sunk, we waited for quite a while and they started to go to the top. The raisins were kind of connected to the bubbles and I thought that the bubbles caused it to go up and down.

I moved onto my last rotation with Whaea Nin, she was doing the super duper hooper loopers. It was a kind of airplane that could fly really far and we also had a example and it flew really far. First we took an long piece strip of paper then glued it so the two end connected. We also did the same to small strip of paper. We glued it onto an straw with the hoops at each end of the straw.

The excitement of science was really fun, the super duper loopers was my favourite part even understanding why it flyed so far. The dancing raisin was fun to look at as it bounced like on an trampoline and the and the fizz inflator it just blew straight up by adding in one other ingredient it was really fun to experiment all of them.

Mind blowing experiments by Faith

This is about our science day on Tuesday 17th May 2016

At first hub 8 had to go to our rotations. My first rotation was in the wet space in hub 8. We learnt about carbon dioxide, the things that you use to make carbon dioxide (which is gas) you will need H2O ( Water ) yeast and baking soda. We used 2 bottles, one with yeast, H20 and sugar. We used them to also create carbon dioxide but with this experiment it only made the balloon inflate a little.

The way we made it was by putting all the ingredients in a bottle and quickly put a balloon on top and you will see that you will create air in your balloon. Choose one of your favourite science experiments. After that we had to rotate to our second rotation. My second rotation was about dancing raisins but the raisins weren't alive and dancing but they were kind of like sizzling.

We used transparent soda/Lemonade. Instead we just used soda water because it was much more cheaper than lemonade or transparent soda. First you had to put your liquid in. Then the next thing you have to do is put your raisins in the cup. If you wait a little bit longer then you would see that the raisins will start fizzing and the bubbles will surround the raisins, if you dip your finger in then the bubbles will surround your finger.

Then we rotated again. Just before my group rotated we drank the soda water. I didn't really like the soda water though. When I went to my last rotation I learnt about a circle plane. It turns out that when they were building planes back in the day they thought of a plane design that had no wings but it had circles on it. The way it worked was that the air in the 2 circles went through the smaller 2 circles causing the plane to keep up and fly straight.

These were the new things that I learnt and they were really fun. I hope that we do more of these experiment soon.

Science week! by Shanya

Mind blowing experiments !

On may the 17th 2016 Tuesday was science day and I was happy! The whole hub got to try out 3 experiments as we rotated around in our literacy groups.

Our first science experiment was the fizz inflator. The fizz inflator was the only one I have seen. We were mainly looking at how it formed, H20 (water) and c02 (Carbon dioxide).  For this project we were in groups of 3.

We used two ingredients which were vinegar and baking soda. We also had 2 objects which were a water bottle and a balloon. When we mixed up the vinegar and baking soda, together we put the balloon on top of the lid and the gas blew up the balloon.

Then the gas started to dissolve and the balloon was beginning to go down.

The second activity we did was the dancing raisins. The dancing raisins activity was easy to make. We were predicting about how it would look like after when we made it. We were in groups of 3 for this project.

For the dancing raisins we used raisins, soda water and a clear cup. When we put in the raisins with the soda water the bubbles started to come to it, then it started to go up and down. After that we got to taste the soda water and the raisins.

Finally our last science experiment was the hoop glider. The hoop glider was what scientist use to predict how planes would look like. The hoop glider can go far away, because when mr Stuart threw his one it nearly got stuck on a gap near the ceiling.

The hoop glider was made out of strong paper, cello tape, hot glue, and  a drinking straw. My hoop glider didn't go that far, because it wasn't even. At the  end we got to have a competition of whose hoop glider would go the furthest. That was our last science experiment.

I thought that the dancing raisins would jump out of the cup and repeat  itself.  I felt really excited in the beginning to the end.

A day of science

It was a Tuesday morning in the  middle Block and we got told today we were going to be doing some science experiments. Then the teachers asked "Who wants to be a scientist?" My hand shot up at 100 KPH. Then they asked us "What type of Science do you want to study?" I answered "Biology, Zoology and Chemistry. Then we began our experiments.

 A few minutes later we began to start the experiments. We started with the experiment Fizz inflator. The ingredients were empty water bottles, vinegar, balloons baking soda, sugar and yeast. To do the experiment first we poured the vinegar into an empty water bottle. Then we stretched the balloon we had, and filled it with a teaspoon of baking soda. Next we carefully attached the neck of the balloon to the neck of the bottle of water. Finally we watched as the chemical reactions and the forces make the vinegar rise and it looked like an eruption and it inflated the balloon, while it also looked quite fizzy. We took a bit of photos and then moved on to our next experiment.

The next experiment we did was dancing raisins. The ingredients were soda, plastic cups and a few raisins. First you pour the soda into the plastic cup. Then we put 6-8 raisins in  the soda. Next they started coming up and down in the cup for a little before they stopped, we also had to record them here's what I wrote: The raisins  were moving up with the carbon-dioxide of the bubbles and when they reached the top the bubbles went down. But they did not do that that well I described them as "They are drowning like old people." We also pretended  that they were on 'Raisins got talent'.  After that we got to drink the soda and eat the raisins.

Then we went on to our final activity the incredible hoop glider. First we had to observe the design and the things the features of the design model plane.I got to help Whea Nin cut the paper strips for the hoops. First we had five minutes to make a small hoop. Then we had five minutes to make a bigger hoop and then we had 10 minutes to put the two hoops onto a straw, it felt like forever but finally we did it. Then we went outside to race them it wasn't easy to see who won, but it I think I came around 6-8 place so I did pretty well.
