Explanation:
1. Watch a ship sail off to sea
Without being in the sky, it is impossible to see the curvature of the Earth. However, you can always see a demonstration of this if you visit a harbor or any place with a wide-open view of the water.If you are able to watch a ship sail off to sea, watch its mast and flag as it fades off into the distance. You will notice that, in fact, it does not "fade off into the distance" at all; instead, you will see its mast and flag appear to slowly sink. The ship sailed beyond the point at which you would see it. Just to be sure, bring a pair of binoculars with you so that you can see even farther off into the distance.
2. Climb a tree
Imagine a vast plane with but one tree smack in the middle. If the earth were flat, your vision would extend exactly as far while standing at the base of the tree as it would when at the top of the tree. However, the farther you climb, the farther your line of sight will extend to the horizon.
3.Watch a sunset
Pick a nice spot from which you can watch a sunset (we'll call this point A). Ideally, you'd have a clear horizon in front of you, and behind you would be some sort of elevated point that you can quickly access (a hill, a building with at least two floors, or perhaps the aforementioned tree; we'll call this point B).
Watch the sunset from point A, and once the sun is out of sight, hurry on over to point B. With the added elevation provided by point B, you should be able to see the sun above the horizon. If Earth were flat, the sun would not be visible at any elevation once it had set. Because Earth is round, the sun will come back into your line of sight.
If you don't have a hill, you could even try lying on your stomach to watch the sunset and then standing up to get a higher line of sight.
