Middle School: OpenSciEd Unit 6.6: How Do Living Things Heal?
OpenSciEd is a nonprofit organization that brings together educators, philanthropic organizations, curriculum developers, and professional development providers to improve science education through the development and implementation of high-quality, freely available science instructional materials. While this work has begun at the middle school level with Grades 6 through 8, the goal of OpenSciEd is to ensure that all educators, from elementary to high school, have access to a free, coherent, rigorous, research-based set of instructional materials that will support all students in meeting the vision for science literacy described in A Framework for K-12 Science Education and the Next Generation Science Standards.

This unit launches with students hearing about an injury that happened to a middle school student that caused him to need stitches, pins, and a cast. They analyze doctor reports and develop an initial model for what is going on in our body when it heals. Students investigate what the different parts of our body are made of, from the macro scale to the micro scale. They figure out parts of our body are made of cells and that these cells work together for our body to function.
Once students have figured out what their bodies are made of and how the parts of their body work together to be able to move, they wonder how the parts of our body heal. They start by watching a timelapse of a knee scrape and notice that over time the part that was scraped is filled in with new skin cells. Students investigate what happens when cells make more cells, what cells need to make more cells, and how cells get what they need to make more cells. Students return to the healing timeline they made at the start of the unit and apply what they have figured out about the interactions between the different systems in the body to explain the various events of healing that took place for the injury at the start of the unit. Finally, they apply their model for healing to explain growth at growth plates in children's bodies as they become adults.
