Science experiment: How does carbon dioxide affect the speed of a boat.

This week we did an experiment with carbon dioxide. We didn’t just do any experiment, we did the coke and mentos boat versus the baking soda and vinegar boat. My scientific question was  How will using a different source to create carbon dioxide changes the function and speed of the boat. I took the coke and mentos boat  13 seconds to make it from one end of the tub to the other. The baking soda and vinegar boat took 4 seconds to make it from one end of the tub to the other. When you mixed baking soda and vinegar there was a chemical reaction and the product of the reaction was carbon dioxide. My hypothesis was wrong  I thought that the coke and mentos will be better and It would be faster but instead, the baking soda and vinegar were more successful.

How is carbon dioxide formed using coke and mentos? When you add coke and mentos an eruption occurs and foam and bubbles come out of the bottle but another thing that comes out is carbon dioxide. But did you know this was not a chemical change at all! To create bubbles, the carbon dioxide needs to interact with itself, which means that the carbon dioxide’s bonds with water in the Diet Coke must be broken. A Mentos candy can help with this. Although the candy from the outside looks smooth, if you looked at mentos under a microscope you would discover that each Mentos has thousands of tiny pits all over the surface. These tiny pits are called nucleation sites these sites are perfect places for carbon dioxide bubbles to form. This rough surface also allows the bonds between the carbon dioxide gas and the water to more easily break, helping to create carbon dioxide bubbles and cause the classic eruption.

Then How is carbon dioxide formed using baking soda and vinegar? Carbon dioxide is formed when sodium bicarbonate reacts with an acid. When you add vinegar and baking soda it creates carbonic acid and sodium acetate. When the baking soda meets the vinegar, there is a chemical reaction and the product of the reaction is carbon dioxide gas. Baking soda and vinegar react chemically because one is based and the other is acid. Baking soda is basically sodium bicarbonate. Vinegar, on the other hand, is a diluted solution that contains acetic acid. There are two separate reactions that happened. The first reaction is the acid-based reaction. When vinegar and baking soda is first mixed together, hydrogen ions in the vinegar react with sodium and bicarbonate ions in the baking soda. The result of this initial reaction is two new chemicals: carbonic acid and sodium acetate. The second reaction is decomposition. The carbonic acid formed as a result of the first reaction immediately begins to decompose into water and carbon dioxide. When this reaction happens the carbon dioxide rises to the top of the mixture. This creates bubbles and foam.

When we first did the experiment, we failed to do it at the first go when we did the coke and mentos experiment. We added too little coke and it failed, then we added more coke and this time we used a measuring cup which made our experiment more precise. For the baking soda and vinegar, we did the measurements correctly but we accidentally spilled baking soda into the tub and we had to do it again. One of my group mates spilled the vinegar and the amount wasn’t really correct but we still continued. It might have affected the experiment because of the amount of vinegar we put in. Next time we could have stuck to one amount instead of changing it, We could also be more careful because we would accidentally spill something sometimes and that would waste time. Science is a very fun subject and I really enjoyed this unit and doing this experiment.

Home Learning share

This week I worked on the water tornado experiment. The water tornado is an experiment of a tornado inside a bottle. You have two bottles and you use waterproof tape to stick the two plastic cups together. Before you tape the cups together you must add 3/4 of water in one of the cups and if you want you can add food coloring or glitter to make the tornado more obvious. You can also and washing detergent if you want just a drop but I don’t recommend it.  Then you turn to the bottle around and then spin the bottle. You will see the water tornado form and the water being filtered to the other cup.

I chose to do this experiment because I saw it online and I thought it was an easy and fun challenge to do about. But when I started to try it I had to go through many times of trial and error. Sometimes I added too much washing detergent and when you flipped the bottle it will create many layers of foam which made the experiment fail. One time I used a tape that wasn’t waterproof and it started to leak and it failed the experiment again. I learned an important lesson that trial and error is very important during science experiments. After a few times, I finally succeeded and I was very happy that I finally did it! Next time I can improve on adding a bit more water to make the tornado last longer and add more glitter to make it look more advanced.

For me, I felt like I spent a lot of effort into this home learning because I had to make an iMovie and I had to get a lot of materials and preparation. I even had to delay the experiment because my sister didn’t have time to help me film. I took me in total one and a half-hour to finish everything, that includes the observation sheet. Home learning is going alright so far. I try to spend as much effort as I can and time to work on my home learning because I know it is important. The next steps that I can take are taking it a little more seriously.

Scientific Method

This week we did a scientific experiment about lava lamps and we used the Scientific Method to help us. The scientific method has six steps. You first need to ask a scientific question to discover about. My question was How is the alkaseltzer tablet going to affect the experiment. Next, you need to find a hypothesis for your question. At first, I thought it would be the tool to make it glow but I was wrong. Be curious and guess what the result will be. Next is the procedure or steps of the science experiment. For the lava lamp, we first add the oil in the cup of water, after that, we add the food coloring for the color you prefer. finally you add the alkaseltzer tablet and you watch the magic happen. Keep in mind that after each step you need to observe. Since oil is less dense than water it floats on the top. It becomes two layers. When you add the food coloring it doesn’t just explode right away. When it goes through the oil it stays as a drop. after it goes through the oil and the water it explodes at the bottom and the color that you chose will change the color of the water. The secret ingredient added at the end is the alkaseltzer tablet. It smells like mint and it is in a pill form. Once you add the tablet the chemical change of all the elements changes. bubbles start forming and everything starts fizzing. The bubbles go up and the top layer starts to produce foam. After a while the tablet starts molding and the lava lamp starts changing color into the color green because the tablet has the color green. The alkaseltzer tablet is made of Citric Acid plus sodium Bicarbonate and that’s the reason why it fizzes.

Overall this experiment was very fun and I really enjoyed it. I hope that we can do more experiments in the future.

Weekly Reflection

This week is the second week of school! This second week has been challenging and it will take some time to get used to. This week we have done many things like our HTWW project, our first week of home learning, decorating our door and many more. The thing I thought was the most important and special was our passion project. This project was done throughout this week and we got to start exploring what we wanted to do for the real exhibition. For our mini inquiry, I did about the Sixth Extinction. This is my favorite piece of work because this Leeds us further to the exhibition. It gave me a brief touch of exhibition and I learned a little bit more about my passion. I used to think exhibition was a huge project and I was a little afraid at the start. Since we did this mini-exhibition I have a brief experience of what the real exhibition will be and it isn’t scary because I know people will guide me and support me through.

I hope by next week I will have got used to the whole grade six procedures and rules and I  hope this year would be the best year out of all.

HWEO Reflection 4

If we were to do this fashion unit again, what would you keep?

I would keep the theme the sun king but maybe change most of the stuff. I would keep the chestplate, the boots, and the cape.

If we were to do this fashion design unit again, what would you change and why?

Next time we do this I would change the helmet, I would change the helmet because it didn’t have a base when it was made and wasn’t made properly. Next time we could buy a frame for the helmet before making it. The second thing we would change is the chestplate. I felt like I could have made it easier to wear on and can make the aesthetics nicer.

How has your learning in LANGUAGE helped you in this unit?

Language didn’t really help in the unit because we didn’t talk much we mainly made most of the stuff by hand not with language.

How has your learning in MATHEMATICS helped you in this unit?

Mathematics didn’t help me much, maybe measuring but we didn’t measure much of our stuff because all of them already fit.

1.What does the Central Idea mean to you?

When designers (like us) are creating, they need to keep in mind the aesthetics of their object and how your object functions and works.

2.Think of the key concept FORM. Explain how FORM influenced how you designed and what you designed.

My costume is the Sun King. The costume looks like a  king that loves wearing fiery accessories, he wears a sun necklace, a sun chestplate, fire boots and lava shin pads . Those are the main parts of our design the other designs are the golden bracelet, the cape and the bronze helmet. He loves the sun and is the king of it.

3.Think of the key concept PERSPECTIVE. Explain how PERSPECTIVE influenced how you designed and what you designed.

Some people thought our costumes helmet looked like a chicken and that was their opinion and point of view. After that we took out the top part and it wasn’t a chicken anymore . In my group we sometimes had discussion that one of the pieces of objects(the helmet) weren’t good because it doesn’t have a base.Some of us disagreed and the other thought it was great.We all had different perspective of it and sometimes changed what we made  because of the perspective of what each individual thinks.

4.Think of the key concept CONNECTION. Explain how CONNECTION influenced how you designed and what you designed.

Connection influenced my group when we were making the helmet we wanted it to be spikes but instead added a galea inspired by the roman helmet.My costume is connected to louis the XIV of france he was know to be the sun king. He became the sun king because he chose the sun as his symbol. Some people also believed the Greek sun god gave him the nickname.

Share 3 learning activities that you really liked

I liked doing the poster for a brand activity and I thought it was pretty fun. I like it because we could get creative and it is easy to do. The second thing is word art because you could decorate a word and it helped me think of new fonts. The third thing is learning about the timeline of art. We saw a slide show and I wrote everything down it was fun to learn about!

Which workshops were most useful for you to turn your design ideas into a reality?

I think the sewing one was useful but they could teach us specifically how to make an object instead of showing types of sewing. Next, I thought the led lights activity wasn’t that good. I didn’t really learn much because people were distracting me and I could not hear the teacher, because the room was too crowded. Next time the teachers and give us a simple task to do and help us with it.

How have you demonstrated the attribute of RISK-TAKER during this unit?

I was a risk-taker when I didn’t know if something would work I would still try it and find new ideas and try them out.

How have you demonstrated the attribute of THINKER during this unit?

I was a thinker during this unit when I thought of the idea of our costume and what we are going to make. I also thought of ideas when a planned failed or when it wasn’t good enough I would think of a better way of doing it.

How have you demonstrated the attribute of COMMUNICATOR during this unit?

I was a communicator when I communicated with my friends and thought of ideas and how to make things better.

 

Young American reflection in progress

We just had 2 days of young Americana,  It was amazing! Our journey started on the early 14th January. For me I was pretty tired but excited that we got to miss school and get to do something even funnier.

Day 1

At about 8:05 we set out our journey to the LLAC. We walked in and the party already started we saw the young Americans dancing so we joined in, we got our welcome and we soon sat down because they were about to show us what our intro to our show was going to be like. But before that he asked us some questions like if we were excited, what instruments we play, what type of songs do we like and so on. Then they performed our intro to our performance to us. The music started playing and they started to dance. After the performance we were all amazed and worried. Many questions were running inside my head, how are we going to learn this in such little time? how do they do it so well? But I should have know that this was just the start. We spent the morning learning all the moves to the intro bit by bit and we soon got it. Then we learnt the middle of the show. We needed to dance to many songs and some parts we needed to sing. I was one of the chosen one’s to sing and I sang the Macarena. I got to one on one a young American and learn how to sing the song because it was in different language and I learnt it really quickly. I soon went back and I kept a piece of paper to read for the practice runs because I didn’t memorise it. I did well for the practices and everyone was impressed and said I did really good for the first time. After our practice run that was the end of the day and I went home exhausted. I couldn’t wait for the next day.

 

Day 2

The second day I was still exhausted and tired to be honest I didn’t really want to do it because I was tired already but it ended our a really good day. In the morning we did some imaginative activities to boost our creativity we made songs, we drew we did of course dance and we had a relaxing morning but all the action was after our break. We learned to do our last part the lion king and our extra ending. My favorite dance was the lion king so I learned it quickly. It took awhile to put everything together but we succeed and did our mini show.

 

During the experience with the young Americans I have improved on my enthusiasm and group cooperation.I really enjoyed the experience with the YA’s and hope to see them again next year.
