We all know that the sun is ENORMOUS. But how big really is the sun in comparison to the earth? Our scientists did a little hands-on exploration last week to show the size of the sun and our earth respectively in relative ratio. We measured a piece of yarn that is about 50 inches long and we attached it onto a piece of sidewalk chalk. We then used this tool as a compass and drew a big circle. Finally we compared the big circle (the sun) with a small red chip (the earth) and realized that the sun is significantly larger than the earth. No wonder we, humans, and all other living things are able to survive on earth - without this great big sun, there would be no lives on earth!
