Today, our teacher said to us that we have a new experiment, the name of our experiment is a balloon. It was a good experiment we did will in my good we take good photos. After we did in our experiment our science teacher said to blog it about it. What you have learned.
Aim: To see which chemical mix creates the most gas.
Hypothesis: (What do I think will happen)
I think the balloon will blow up because the gases make carbon dioxide. I think the vinegar will make or add more gas.
Materials:
- Two plastic bottles
- Two balloon
- Salt
- Baking soda
- Vinegar
- Soda water
Steps:
- Get the two bottles and two balloons
- Get the vinegar and soda put it into two different plastic bottles
- Get the balloon and put the baking soda or the salt
- Put the balloon into the plastic bottle
- Wiggle the balloon so the baking soda or the salt will go down to the vinegar
- You will see how cool is this experiment and take some photos, have fun.
My images:
The blue balloon is the one that didn't work but the balloon makes bigger but suddenly going small, so our group ask the teacher that can we do another one. Our teacher said yes so the other experiment is the pink balloon but still didn't work. I and my group we size it how big is it. Even didn't work we saw that the balloon can make it bigger. After we take it photos and then blog it what we have done was the experiment is good.
I think this experiment is awesome because we knew that the vinegar and baking soda will make the balloon blow, same as the vinegar and the salt. It's ok that the one didn't work we see the other group work so our one something mistake or the balloon has a whole on it.
Balloon 1
( 3 tsp baking soda, ½ cup vinegar)

Balloon 2
( 3 tsp salt, ½ cup soda)

Balloon Size (cm)
| 4cm | 3cm | |
Bubbles
(small, medium, large) | small | small |
Conclusion:
I really enjoy our experiment even our group didn't work but we can see that the balloon is trying to blow up. Even our experiment didn't work we still see it and we had fun about our experiment, it was so good taking pictures of it and post it on the blog. We also found out that we can make carbon dioxide. The blue balloon and the pink balloon didn't work I don't know why didn't work but we saw it how the balloon trying to blow. Thank you all for reading my blog post about Hurumanu-Balloon Chemistry Science.
Hi JV, I really like your hypothesis and prediction that the chemical reaction would create carbon dioxide. In your conclusion you have talked about the carbon dioxide again, this is good because you have linked your conclusion back to your hypothesis. There are two things that I think you can do, the first is to add some cations below your images so that your readers know exactly what is happening in each image. The second is that the "Findings" heading goes with the chart where you have recorded your data. You need to move the text you have written under "findings" and put it in the conclusion.
ReplyDeleteIn your conclusion you should write about what happened in both of the experiments - talk about the width of the balloons and the bubble sizes. 1 sentence per experiment. This will add your scientific findings to the conclusion.
Keep up the great work JV!
