I never knew that!
Hola Bloggers! Today I will be blogging about science. Last week on Friday and today I did some science. Last week I had nothing to do so I thought I would search up science experiments! When I did it came up with how to make a balloon blow up by itself! And I immediately watched the video and had all the things I needed and started. If you want to try it out here is the instructions: First make sure you have Vinegar (Any type), a balloon, Baking soda, and a bottle preferably a small one. Then you can start.
So again first, measure 1/3 of vinegar then pour it in a bottle.
Second, put 1 teaspoon of Baking Soda in the balloon.
Next put the end of the balloon on the bottle.
Make sure to take the lid off and do not get any baking soda on the bottle yet.
Now finally, lift the balloon up so the baking soda falls then let go and step back!
It will blow up by itself.
Last week I did it and it was so good, so this week I decided to try and see what happens if I did it with a different vinegar and it had the same reaction. Or maybe not my brother was helping me and he put a tad to much baking soda. I also did one with my brother and we had two glasses of water half way in one we put an egg and in the other we added a lot of salt then the egg it worked.
The one that had salt in the egg floated and the one that didn't the egg sunk to the bottom.
The reason for that is the more density there is the easier it will float. In the ocean it has more density so it's easy to float but in a lake it does not have salt so it has no density. Which means it's harder to float. The first time we did it I said to fill the cup up all the way so it didn't work the first time but we tried again with the water half way in the cup and it floated!
I had so much fun in the end of the first experiment I did at the top when I took the balloon off it sort of blew up and the bit of vinegar that got in the balloon went everywhere!
I hope you enjoyed my blog post! If you can please comment below and
here are some photos and a video!

Hola Angelina!
ReplyDeleteThat was a very cool experiment. I really like how you added that GIF of the balloon blowing up, it’s awesome. How big did the balloon blow? I love how you explained in the second paragraph how the egg floats. I never knew that salt gives density. Your blog post is very detailed and interesting. A big thumbs up for that. How did the first day of school, Wk 6 go?
Thanks for sharing. It was a very good blog post, Angelina.
Keep safe and be kind. Keep up the great work. Blog you later!
Malo e lelei Angelina! Wow, I'm so impressed that you went looking for Science experiments online. These ones that you tried sounded particularly fun, although I'm not sure your parents will agree if the vinegar went everywhere! Your explanation of why one egg sinks and the other doesn't is clear. Do you know why the balloon blew up? As always, thanks for the informative and well constructed blog post Angie - ka pai!
ReplyDeleteHi Angelina
ReplyDeleteWhat a great use of initiative looking for activities you can engage in. The internet is a wonderful tool for that! Why did you choose science experiments to work on? Is science a subject you are particularly interested in? Perhaps now you have worked out the proportion of vinigar and soda, you could make a volcano, the soda and vinigar mix being the lava. Ive seen it done where kids make the volcano with paper mache and leave a good sized hole at the top for the lava to flow through.
Keep up your awesome effort and dedication to learning and we will see you back at school soon.
