Tony and I visited Mr Hope's last two Science periods today. As a special feature for his Astronomy unit, we talked about celestial objects, Moon phases, Pluto's demotion, nuclear fusion, galaxies, etc.
Tony had done the presentation yesterday. So he had some comfort with the kids and the timing. He did the first run today; I delivered to the second class.
I didn't do a great job. It was good having Tony there to assist. Kept me moving along, corrected my mistakes. The grade 9 students were great in my session. Lots of excellent questions.
