My horse floated in the bucket of water.If you push it to the botom it will come right back up to you.After I was done testing my horse I had figured out why it was floating...because it had less mass in it.
When I put a pinecone in a bowl it floated in water.Once I cleaned up everything and pored out the water,I thought about why the pinecone floated and I realized that it was because it weighed less than the water and because theres air in the center. ( Nathan Blais hellped Me)
My toothpick floated and it looked like sombody has bitten out of it and it also looked like sharp teeth because they were pointy. [ my sister lizz helped me out by givin' me some addvice].
I tested out a,sponge and it floated.I think it floated becauseit was light.I tested out a soda can and it sank I think it sank because it was full. I tested out an emtey can of soda and it floated. I think it floated because it it was emety and because it hade air in it.I also tested out a bag of water and it floated.I think it floated because it was light. I tested out a hair brush and it floated.I think it floated because it was not hevey.A nother thing I tested out was a metal spone and it sank.I think it sank because it was metal.
When I tested my sunglasses it floated just like my toothpick so I put some weight on one side and the other side still floated and it looke really weird and I also tested one of my brothers heavy truck and it had a pointy edge and it put a hole in the bowl that I was using and it sank to.
