12. High School Science Standard: Engaging in Argument from Evidence
19:08||Season 1, Ep. 12In this episode, I give a quick summary of the interview with Christie del-Castillo Hegyi and Jody Segrave Daly that aired on Science Fare on Monday, June 17, 2024. Christie and Jody are the founders of the Fed is Best Foundation and authors, along with Lynnette Hafken, of the forthcoming book, Fed is Best. In today’s episode, we talk about:*The Next Generation High School Science Standard entitled, “Engaging in Argument from Evidence.” In this standard, high school students are asked to evaluate the claims, evidence, and reasoning behind currently accepted explanations or solutions to determine the merits of arguments. I ask Christie and Jody how their work demonstrates this standard. [3:33];*The advice Jody and Christie would give to high school students interested in science [14:50]11.

High School Science Highlights
22:17||Season 1, Ep. 7At the halfway point of Season One of the Science Fare podcast, let’s have a listen to this special High School Science highlights episode — a collection of clips from previous episodes when the scientists link their work to the high school science learning standards. We have Hashim Al-Hashimi (Episodes 1 and 2) talking about how complexity evolves, Jamie Morton (Episodes 3 and 4) talking about the scientific process and feedback in biological systems, and Kelly Knudson (Episode 5 and 6) talking about how strontium gets into bones. Specific timestamps:*Hashim Al-Hashimi: New York state high school curriculum in Life Sciences disciplinary core idea: “Although DNA replication is tightly regulated and remarkably accurate, errors do occur and result in mutations which are also a source of genetic variation.” How can we think about mutations and the evolution of variation in terms of a sweet spot between evolutionary fitness and peril? [2:10]*Jamie Morton: In the Maryland state high school curriculum under the topic of The Nature of Science, students are expected to master the idea that “scientific inquiry is characterized by a common set of values that include logical thinking, precision, open-mindedness, objectivity, skepticism, replicability of results, and honest and ethical reporting of findings.” How did the study on autism and microbiome incorporate some of these values? [9:50]*Jamie Morton: Also in the Maryland state high school curriculum, we have the Life Science learning standard that says, “Feedback mechanisms maintain a living system’s internal conditions within certain limits and mediate behaviors allowing it to remain alive and functional even as external conditions change within some range. Feedback mechanisms can encourage through positive feedback or discourage through negative feedback what is going on inside the living system.” Can we talk about the microbiome and autism in these terms? [14:25]*Kelly Knudson: In the Arizona state high school curriculum, in the Chemistry section of the learning standards, students are asked to “explain how the structure of atoms relates to patterns and properties observed within the periodic table.” How does the way Strontium gets into bones relate to this idea? [17:30]6. Part 2 of Kelly Knudson on Using Archaeological Chemistry to Help Understand Feasting at a 2000-year-old Site in Peru
28:29||Season 1, Ep. 6Part 2 of the conversation with Kelly Knudson, professor of Anthropology in the School of Human Evolution and Social Change at Arizona State University, and director of the Center for Bioarchaeological Research and the Archaeological Chemistry Laboratory, who talks to us about archaeological chemistry, her path as an archaeological chemist, and about a paper she and others published in PNAS entitled “Feasting and the evolution of cooperative social organizations circa 2300 B.P. in Paracas culture, southern Peru,” in which the chemical isotope data help determine where objects at a feasting site came from, and from there, lead to inferences about the evolution of social complexity at the site. We discuss: *What Kelly and her colleagues learned about where the objects at the site were from [2:45]; about 25% of objects coming from significant distances, and interpret that to mean the feast-goers were coming from significant distances [3:00];*Were the results expected? Surprising? [3:54];*What kinds of distances are we talking about, and how does the concept of distance today differ from what it may have meant in the past? [6:30];*How the archaeological and chemical data come together [9:30];*What happens when the archaeological and chemical data conflict? An example [12:45];*How the field of archaeological chemistry has changed since Kelly was in graduate school [16:49];*What excites Kelly the most about archaeological chemistry research — trying to understand what people’s lives were like the past [17:40];*Connection to an Arizona state high school science learning standard on how the structure of atoms relates to patterns and properties observed in the Periodic Table [19:10];*Kelly’s memory from high school science — an AP Bio project that was her first “field” experience and how much she loved it [23:45];*Kelly’s advice to high school students interested in science — explore, be attuned to what interests you, be open to new paths and opportunities that open up [26:00]5.
