You can actually see that the earth is curved ever so slightly from a high place in the ocean
One mathematical evidence that can prove the Earth is round is the observation of the curvature of the Earth's surface. As one travels long distances, the angle of the horizon changes, which can be calculated using geometry to show that the Earth is not flat but curved.
there are people all around you. Isn't that proof enough?
Yes, by using the sun's estmated age. The Earth is about 4.6 billion years.
You can observe the color, texture, shape, and temperature of an object using your senses.
Columbus did the most to prove the earth was shaped like a ball. He did this by sailing to America, and proving to Europe that the world was not flat. Edit: a lot of people think that, but it was established by the Ancient Greeks about 1800 years earlier.
You are leveling the line 90 degrees to the center of the Earth. If your line isn't level, the bubble will rise away from the center of the earth.
using your senses to gather information is called "Analyzing Data" CD1F95BD-C4A8-BDD9-427B-0A2A6C0347A5 1.03.01
Objective data is what a person perceives using the senses. In medical terms, this is also known as a sign.
Using any or all of your 9 or so senses to examine your environment is organoleptic analysis.
Properties that can be detected using the senses include color, texture, temperature, odor, taste, and sound. Our senses help us perceive these properties in the world around us.
Information that we obtain by means of our senses is called observation.
the process in which the senses are used to gather information is
