Here are scaffolded notes for the TED ED Video "The Wacky History Of The Cell Theory." This video is a great video to watch when introducing the Cell Theory to your students.
Also I put the TED ED questions that were made for the video from the website. I do not take credit for those questions, but I wanted to add them as a FREEBIE! You can use these questions for group quiz, group work, individual quiz, quick discussion questions, or homework! Its up to you!
