Is the human body part of your science or health curriculum? Are you looking for a way to 'bone' up your lessons? Maybe you have some fast finishers who would love a hands-on activity to show-what-they-know!? Or possibly, these learning center activities could be used for extra credit in your classroom? There are 9 printable, ready-to-go activity centers about topics that relate to the human body. They are a great way to differentiate your science curriculum if you are teaching the human body to upper elementary / middle school students.
