Notes from our own research
1. If you put a stick in the ground for example throughout the day it will change where it goes not just because of the sun but if the earth was flat we would have to move it in order for the shadow to move.
2. Sometimes you might see a boat come over the horizon and it looks like it is come out of the ground or water but it is actuallygoing up be cause the earth is a sphere if it was flat it would just appear out of nowhere.
3. If you ride a plane you can see that you can ride for a pretty long time and not fall off any edges but also sometime you can see over the horizen and it looks almost like ea hill or a sphere.
