Lesson Topic
The Solar System - Overall Scale
Lesson Outline
I had barely walked into Jared's room when he excitedly asked me if I had recently checked the website 'Astronomy Picture of the Day' - Jared was enchanted with the video that had just been posted, and wanted to share it with me. It was a 3-minute video on the exploration of other worlds, voiced over by Carl Sagan. Following that, we discussed the pros and cons of space exploration/travel - Jared was very curious about the Challenger disaster in 1986, and its consequences. He had some very relevant questions regarding the origins of spaceflight, and so we discussed Robert Goddard and Wernher von Braun and the early history of rocketry. We covered some basics of orbital dynamics, a topic we will concentrate on next semester, also in the context of planetary motion. Jared appears to be fascinated by the concept of 'physics' (e.g. Coriolis forces, spacecraft orbits, etc) and shared some stories with me of how he recently had to explain certain physical concepts to some of his friends. We concluded the section on the scale of the Solar System, by scaling the planets to the Sun if it had a diameter of 22 inches (the diameter of a tire/wheel on one of the Renntech cars). The rocky planets would then all be under a half inch in diameter, while the gas giants would only be a few inches across.

Lesson Comments
Jared appeared to be very engaged today, despite the fact that he was absent yesterday. He again had so many questions, and it was heart-warming to see that - again - he has done his own research on the internet looking for interesting space-related topics. It was difficult to stay on the subject in today's class for all the relevant and insightful questions Jared had - but I always try to take the time out to address Jared's questions. A delightful session, again.
