The way boats float is caused by how much air is inside of them. Nanogirl explained this by showing us with tin foil and rolling it into a ball, it sank! Then she had it flat and it floated! Magic? No! The reason for this is because the rolled tin foil weighs more than the water and there is also no air inside it to balance it out because air weighs way less than water. The flat one has a lot more space around it to make it float and also is not too bunched up and heavy.
The types of boats I made were. Traditional that kind of looked like a hat, a canoe that looked a lot better in the video than it did when I made it, the one Nanogirl made, and one made of straws hot glued together.
I found it hardest to make the canoe, it had lots of very complicated folds but I persevered and got there in the end. The straws one was the easiest to make because it was just hot glue.
Thank you for reading my blog. Here is my hypothesis and the results of my boats:

What an awesome Nano Girl activity I used to love making origami boats when I was a kid and racing them down the river with my brother!
I think you did an amazing job introducing and explaining the activity, including a hypothesis and your results. You completed this activity in a very scientific manner.
It is great that you included videos as well so we could see how your boats held the weights differently.
What would you change about your boats to improve them?
Keep up the good work and I hope to see more of your posts during the Summer Learning Journey!!

Kia ora Kylah,
ReplyDeleteIt’s Fiona from the Manaiakalani team. It’s great to see you giving the nanogirl challenge a go!
I really like your boat designs. What a great idea to compare several different designs to see which one could hold the most weight. It was good to see you using your scientific knowledge about what floats and sinks to help you with your designs. I wonder which design would be the best at moving forward in the water?
I can’t wait to see what other awesome creations you come up with over the summer.
