SCIE 113 Speaker Series Worksheet This worksheet is designed to help you analyze arguments presented by speakers at the SCIE 113 speaker series, to concisely summarize their most important points in your own words, and to keep track of sources of information – all important skills that we will practice and apply throughout the course. This worksheet will also be a useful resource if you use information from the speaker series in Essay 1 or the final project. However, this worksheet is not intended for extensive note-taking, and we recommend that you take notes elsewhere before summarizing your answers on this worksheet. Please try to answer questions in 2 sentences at most, unless otherwise noted. Background questions (not for marks, but your TA may give you feedback on these) 1. What is the speaker’s name and job title? Dr Michelle Kunimoto is a postdoctoral fellow at MIT’s Kavli Institute for Astrophysics and Space Research 2. What is the speaker’s discipline or background in science? Using the APA style guide on Canvas, provide a reference for the source where you learned this information. Combined Honors in Physics and Astronomy. Research Area: Exoplanets Michelle Kunimoto Discovers Four New Planets. (2018, May 4). UBC | Undergraduate Programs and Admissions. https://you.ubc.ca/ubc_stories/michelle-kunimoto-planet-discovery/ 3. Using the APA style guide on Canvas, provide a reference for this speaker’s presentation. Video Conferencing, Web Conferencing, Webinars, Screen Sharing. (n.d.).

What is one question that you would like to ask the speaker? ( 1 point ) Is it possible to find rogue planets using the transit method? If not, how were we able to discover those types of planets? 5. What was one thing you learned that you found particularly interesting? ( 1 point ) There exists a planetary system which hosts three potentially habitable planets. Imagine going on vacations to different planets. © SCIE 113 2023

6. In what way does this presentation relate to what you have learned in SCIE 113 so far? ( 1 point ) ( Note : This question does not apply to the first speaker series presentation of the term.) Based on the claims activity, this presentation provides strong evidence for the claims “good science cannot be done without good theories and “observation is central to all of science”. The methods and approached used in the investigation are based on previously proven theories and the results are entirely dependent on observations. Questions marked for content (7 points total) Note : If the speaker has discussed multiple research projects, please choose one research project to write about for the following questions. 7. What is the speaker’s research question? ( 1 points ) How common are planets like our own and is there other life out there in terms of size and habitability? 8. What approaches or methods does the speaker use to investigate the research question? ( 1 point ) She took an Earth centric view of what it means to support life. This means assume that life needs water to survive, the planet is roughly 0.5-1.5 times the size of Earth, the planet orbit’s in its star’s habitable zone and the planet’s host star is similar to our Sun. Use of the transit method. 9. What is the main claim that the speaker makes about the research project? ( 2 points ) Planets smaller than Neptune are the most common planets out there according to the data gathered from current technological equipment and their limitations. We have found dozens of planets that are small like the Earth and in their SARS habitable zones, and estimations suggest about half of Sun like stars host Earth like exoplanets. 10. Using point-form notes, list examples of relevant evidence that the speaker presented to support the claim that you identified in question 9. ( 3 points ) -the explanation of the validity of using pulsars, radial velocity method, the transit method (used in Tess) to find exoplanets -Kepler mission found 2708 confirmed exoplanets and 2054 candidate planets -NASA’s exoplanet finding mission Tess found 385 confirmed exoplanets so far and there are 4465 candidate exoplanets that are potentially planets -plotting all the confirmed exoplanets discovered from the various methods and missions on a graph that shows the size of the planet plotted against the orbital distance shows that a majority are smaller than Neptune. © SCIE 113 2023
