In this lesson, students will understand and describe the two main types of telescopes: reflecting and refracting. We will kick off with a discussion on their differences, including the use of lenses and mirrors. Students will work on designing their own telescopes with provided equipment and materials they bring. We will also cover key vocabulary terms such as Dobsonian and focal length. Prepare for a quiz on January 14/15 to reinforce your knowledge about telescopes and their components.
