This little worksheet is formatted like a "big kid" worksheet, but is meant to answer one of the common questions young children ask. Other questions I want to answer in future worksheets are: What does my heart do?, How do we breath?, Why do we drink water?, Why do we have to sleep?, and more. Students color as they read each step in each process. If students need help reading, the teacher would help, and might want to do a wrap-up at the end to make sure they understand.
