Welcome to the bizarre world of neutron stars. These are some of the strangest objects in the universe. This class will guide learners to a better understanding of the truly unique objects in space. We meet once a week in a live video class. I present a slideshow and talk over the features that are the week's topic. Most of the class is lecture-style with me explaining neutron stars. I frequently stop and ask questions, and learners are always welcome to ask their own questions throughout each class. I also give recommendations of notes to take or things to write down to enhance the learning experience. Learners will also have several opportunities to create diagrams and sketches to illustrate the phenomenon we discuss in class. I am an enthusiastic educator who is very excited to share my knowledge of neutron stars. Learners with all ranges of background knowledge are welcome, but know that I do address several advanced physics concepts in the class. I don't go over any of the math calculations behind the concepts, but some of the concepts will seem very strange. Some of these concepts include: basic field theory in particle physics, superfluids, nuclear pasta, and radioactive decay. Feel free to reach out if you have any questions or concerns about the class content.
學習目標
Learners will understand and be able to explain the unique properties of neutron stars, including their magnetic fields, radiation emission, and spin rates.Learners will know the process of a supernova and how this process leads to the creation of a neutron star.

Triggering a Supernova
Learners will:
~ Understand that the core of a red supergiant can only be maintained up to a certain point, and after that point the core will collapse
~ Know the importance of the particles in the star's core

教師專業知識和證書
學士學位 在 教育 從 St. Cloud State University
I have a bachelor degree in education from St. Cloud State University in MN. Since then I have kept updated on teaching techniques by attending yearly meetings of Education Minnesota, as well as following common education journals. I have been teaching homeschoolers ages 6-21 for 18+ years. During that time I've taught all traditional subjects and found ways to tailor them to the needs and learning styles of all learners. I have taught math, chemistry, and physics on Outschool for 4 years.
I have studied particle physics and astrophysics for the past 3 years, and continue to attend lectures to broaden my base knowledge and help me teach the most up-to-date material possible in this changing field. I make sure to keep updated on the advancements made by Fermilab and Cern, two of the leading particle physics facilities in the world. Most of the lectures I attend are through Fermilab, which exposes me to some of the most up-to-date and widely accepted ideas in particle physics and astrophysics.
During my time teaching I've had many learners ask about the subatomic world and what we know about it, which has helped me create strategies in teaching this content.評論
