We watched Bill Nye Sun or Brain Pop Sun (subscription required) and did Cloze notes.
Made a Sun Cookie Model with sugar cookies, frosting, red and yellow sprinkles, mini chocolate chips and pull and peel Twizzlers.
Students modeled the interior, atmosphere and features of the Sun. YUM!
Update: We needed more... so I made foldable notes that sudents could model the Sun before making the cookie and exit ticket to make sure they knew their facts. For students that finished early (and a few with allergies) I made a vocabulary puzzle.
