In this Mystery, K-5 students consider what would happen if their body didn't have bones. In an activity that combines science with art, they trace their hands and then add see-through bones to their picture, making their own skeleton hand. The activity includes an extension for older grades in which students compare their hand bones to the bones of a mystery animal.
TEACHERS, BEFORE YOU TEACH THIS LESSON… PLEASE READ!
What follows is our Halloween mini-lesson and activity that we created in 2017, so it’s possible that your students did this with their teacher last year. If it’s important to you or your students that you do something new this year, we recommend trying our Halloween mini-lesson and activity for 2018, "What’s the biggest spider in the world?"
What do bones do for your body?
