SC300 Big Ideas in Science Unit 9: Life Out There? Prof. Christopher Herren AIM: DrChrisHerren

Agenda 1.Incomplete requests 2.Unit 9 Outline 3.The Universe 4.Extraterrestrial Life 5.SETI 6.Q & A  Unit 9 Final Project

Incomplete requests An ‘Incomplete’ allows limited additional time to complete coursework after the term’s end. You should have completed 75% of the coursework. Requests for an Incomplete, with a detailed explanation why, must be made by to your instructor by Monday, May 23, All class work must be completed by June 10, See the KU catalog for further information.

Unit 9: Extraterrestrial Intelligence Read chapter 23 about genetics and reread chapter 1 (pp ) about SETI and scientific research. Discuss the randomness of DNA point mutations and their consequences. Science Meets Real Life Final Project exploring how you apply different aspects of science in your daily life. Seminar will discuss the search for extraterrestrial life!

The Universe There are billion galaxies in the entire universe… with billions of stars per galaxy… that’s stars in the entire universe!! Only 429 exoplanets known Image credit:

The Universe If stars… each have an average of 3 planets… that’s 3x planets in the entire universe. If the chance of extraterrestrial life is only 1 in a trillion, then there should be 30 billion to 3 trillion living planets!! Image credit:

Search for ExtraTerrestrial Intelligence SETI uses light, radio, and microwave telescopes to search the universe for unnatural signals from space. SETI ( ) was an informal association of NASA, various universities, and astronomy institutes. SETI ( ) was a U.S. government funded intensive look for extraterrestrial intelligence. SETI ( present) is again an informal association of NASA, various universities, and astronomy institutes.

What do you think… Most SETI projects involve surveying the sky with massive radio and optical telescopes that are designed to listen and watch for signals that are made up of non- random patterns. 1.What do you think scientists expect to find through SETI and

What do you think… 2.Why do you think NASA chose to eliminate funding for SETI in the 1990s?

What do you think… 3.Do you believe SETI and are worthwhile projects? Why?

What do you think… 4.What outcome(s) do you think will result from SETI and

Beyond SETI: Darwin Constellation Darwin was a proposed constellation of space telescopes cancelled in The idea is that if ozone, liquid water, and carbon dioxide are found together, it’s a very strong indicator of life. Image credit:

Unit 9 Final Project (250 points) Unit 9 Final Project due by 11:59 PM ET, Tuesday, May 24, NO LATE FINAL PROJECTS ACCEPTED! Explain everything in detail. Don’t assume I already know what you mean. Support your explanations with referenced information. Science is about verifiable facts.

Unit 9 Final Project (250 points) Image credit projects/project_scientific_method.shtml Part I: 2 Scenarios to address with the Scientific Method USE THE METHOD STEP-BY-STEP. Clearly state hypothesis. A hypothesis is a If…then statement, not a question. Part II: 5 topics about Science in your life step Scientific Method

Unit 9 Final Project (250 points) 1,500 words minimum Informative Essay: 1.introduction 2.body 3.conclusion 4.references APA format Find good references!!

Unit 9 Final Project (250 points) Part I Scientific Method 1.Scenario 1: You arrive home late at night. You walk up to the front door, unlock it, and reach in to turn on the light switch located just inside the front door. The light does not come on! Now what? 2.Scenario 2: Develop your own detailed problem/observation and apply the scientific method to solve.

Unit 9 Final Project (250 points) Part II Why I Cannot Live With/Without Science 1.Describe a typical day & specifically point out how science impacted it. 2.How has science improved your quality of life and explain why? 3.What are the negative impacts of science and explain why? 4.Could you survive without science and explain why or why not? 5.How has this course impacted the way you view science?
