Credit: “Causation: From Stars to New Elements”, OER Project, https://www.oerproject.com/PurposeIdentifying the causes and effects for the birth and death of stars will help you see how complexity increased and how Thresholds 1, 2, and 3 are connected.Process1.As youlook at the slideshow “What Did Star Stuff Give Us?,” list the effects of star formation in the table below.Effects of star formation2.Decide which of the following are causes and effects of star formation by labeling the causes with a “C” and the effects with an “E.”Causes and effects of star formationLabel with C or EThe first stars form.Denser clouds of hydrogen and helium cause gravity to increase.Stars run out of fuel.
BIG HISTORY PROJECT / LESSON 2.4ACTIVITY CAUSATION: FROM STARS TO NEW ELEMENTS2Causes and effects of star formationLabel with C or ETemperature reaches 10 million degrees Celsius.Stars explode in supernovas, creating even more chemical elements.Gravity pulls matter together, forming clumps of hydrogen and helium.Stars use elements as fuel and create new elements.Collisions between atoms increase temperature in the clumps of hydrogen and helium.3.Complete the following portions of the Causation Tool (on page 3): write the event details, categorize the causes, label the triggering event, and list the effects.4.After you’vecompleted the tool, answer this question: Why is the death of stars important?
