Carl Sagan, a famous astronomer and author, once said that if you saw Earth from far away in space, what you would see is a pale blue dot. Our planet appears this way because 70% of it is covered in water. Every living thing on this planet owes its existence to that miraculous molecule.
In the next two weeks, we will be studying Earth's water systems and we will analyze water in our local ecosystems.
Tell a story about a body of water that you visited (lake, river, ocean, etc). Describe the ecosystem that existed there. What types of plants and animals did you notice? Was the ecosystem healthy, in your opinion? Why or why not?
