The skin on your feet peels off in space?! Who knew?? This reminds me of the Grossology series. One of my colleagues taught 5th grade science back in the day, almost exclusively through the use of Grossology and Ripley's Believe It or Not. I really liked the explanation that was given with the foot fact, and it's a good push for students to go beyond the gross factor. Investigating why things are the way they are is an important critical thinking skill. And with short video clips, Ripley's and Grossology, there could be a focus on non-fiction text and strategies for reading critically.
