My name is Tony Ceraso and I will be your instructor. I sometimes run the planetarium and have written curriculum for the National Air and Space Museum in Washington, DC. I have also written curriculum for NASA’s school visitation program and teach on the college level in NJ.
My goal is for you to thoroughly enjoy this lesson. I love astronomy and I want nothing more out of our time together than for you to have a greater appreciation for the universe through the understanding of this material. Besides the lesson I’m going to preview for you now, the course includes warm up activities, test questions, and cross-curricular activities for you to download as a supplement.
