Science Fare

In this mini episode, Dr. Shauna Henley tells us about the importance of pH in canning food. Tune in next week for the full-length interview.

Welcome to the Science Fare podcast! On the Science Fare podcast, I bring you conversations with scientists doing fascinating, cutting-edge work on all kinds of interesting phenomena, ranging from physics to chemistry to biology and even the nature of science itself. In the conversation, I help draw connections between the scientist's research and part of the high school science curriculum. In Season 5, new episodes come out every Wednesday, featuring a mini episode that focuses on the high school science connection and then the following week, the full-length interview.

Science teacher extraordinaire Carla Guarraia,who teaches at The Park School of Baltimore and is also the chair of the Upper School Science Department, tells us about her path to pursuing science and then science teaching, the way she integrates research into her teaching, and gives advice to students interested in pursuing science. Resources mentioned in this episode:Carla’s Park School faculty page The Shape of Wonder by Alan Lightman book The Plastics Paradox by Chris DeArmitt book Precious Plastics Manor Mill Science Friday podcast episode about plastics contamination Please click below to fill out the survey for this episode:Science Fare Podcast Feedback FormScience Fare Podcast website Highlights of the episode:*Opening quote by Carla on appreciating that learning should feel hard[0:01];*Susan introduces Park School of Baltimore science teacher and upper school department chair Carla Guarraia and they thank Manor Mill for letting them record in the space [1:08];  *Carla talks about her path to studying science and becoming a science teacher [3:43];*What Carla joins most about her job as a high school science teacher [18:30];*How Carla integrates research into her teaching with a focus on two classes — plastics and integrative medicine [22:05];*Deeper dive into Carla’s work on the International Student-led Arctic Monitoring and Research (ISAMR) program [35:33];*Carla’s advice for high school students interested in science [47:48]

In this mini episode, we hear from science teacher extraordinaire Carla Guarraia who teaches at The Park School of Baltimore and is also the chair of the Upper School Science Department. Carla tells us about an innovative plastics class she teaches that challenges students’ views on plastics and gets them involved in research on plastics. Tune in next week for the full-length interview and the last episode of Season 4! Please click below to fill out the survey for this episode:Science Fare Podcast Feedback FormScience Fare Podcast website

In this mini episode, astrobiologist Sean Jordan (Dublin City University) talks about his lab’s work on lipids and the origins of cell membranes. While the earliest cell membranes, aka protocell membranes, were quite different from the cell membranes of today, they also share some important biochemical similarities. Please click below to fill out the survey for this episode:Science Fare Podcast Feedback FormScience Fare Podcast website
