1 Objective: You will know that the creation and distribution of elements has led to the formation of our planet and the creation of life.

2 Task #6 In your science notebooks, make an entry for today (11/18/2011) called SCR #3. Then, answer the following question, using at least 2 complete sentences: Where and how are elements created?

3 How old is the earth?  Scientists believe the earth is about 4.6 billion years old.  How much is a billion? http://www.youtube.com/watch?v=jTmXHvGZi SY http://www.youtube.com/watch?v=um0guhNG PPM

4 How did earth form? Scientists believe the earth formed about 4.6 billion years ago when a giant cloud of gas and dust collapsed to form the solar system. The gas became hot and dense enough to create the sun. The remaining gas and dust formed the planets. www.discoveryeducation.com

5 When did life first appear on Earth?  Scientists believe life first appeared on our planet about 3.8 billion years ago. Life as we know it would have never been formed if there was no water. So, where did the water come from and how did it help life to form? http://www.youtube.com/watch?v=kTAjQDatyo Y&feature=related

6 How did life form on Earth? Scientists believe that elements dissolved in the early oceans began to group together and, with the help of lightning, formed the first organic compounds and then the first life forms. www.discoveryeducation.com

7 What is the proof?  The proof of how and when the earth began comes from looking into the past. Scientists look at rocks and fossils.

8 The Result? Billions of years of element creation, the collection of these elements in just the right combinations, and a lot of luck have given us this… http://www.youtube.com/watch?v=thuViaxRd_ w&feature=related

9 How will life on Earth end? http://www.youtube.com/watch?v=WFp0m8ih mzY
