I conducted an experiment to explore how water resistance acts on different objects.
I made three paper boats. One was big, one was small, and one was square.
We placed them in a bath, and I blew the boats to the other side of the bath.
Here are the videos of the experiment:
I observed that the boats did move a different speeds: the square boat went the fastest, the small boat wet the slowest, and the big boat was faster than the small boat but not as fast as the square boat. I think that the square boat was most successful because no water got into it, and it turned into an edge which had the least amount of water resistance.
I expected the small boat to be the fastest because it weighed less than the big boat, and it was pointed, but it turned so it had more of a flat edge, so there was more water resistance when the boat moved.
The one that failed was in the water for a long time so it got really floppy and didn’t stand up. Other experiments I could try to test water resistance could be going in a swimming pool and moving my hand through the water at different angles. This way I could feel the water resistance on my hand.
