“The students were amazed to learn how many bones make up the entire skeleton; and, even more so to recognize how many are in the human hand, wrist, and forearm! Their individual "x-ray" drawings showing all bones in their hand were truly incredible given I teach 6-8 year olds! Thank you!”
· Vicky · Teacher
“Very fun and engaging with very little to prep. I had pretty much all the materials at school and I brought only the oil and q-tips from home. The children loved it, it satisfied or standards, and they look great hanging in our windows still.”
· Kristi · Teacher
“It was all really great, and my class (K-1) was fascinated by the ideas presented. We stopped the video and tried to walk around with "no bones". I appreciated the step-by-step, detailed instructions for the art project that followed. We watched once, then we followed along with clipboards. Our skeleton hands came out great! ”
· Gina · Teacher
“The activity turned out awesome! I did it with first grade, so I wasn't sure how their drawings of the hand bones would turn out, but they did amazing! The tutorial was great, and we loved the final product. The "x-rays" are hanging in our windows!”
· Kellie · Teacher

· Carolyn · Teacher
“The kids were so excited to make a drawing of their "own" skeleton. The see through effect with oil was really cool! As always - well explained and high interest level! A few kids had done it last year and it didn't make a difference in their engagement!”

“When I saw this lesson, all my lessons for the day went out the window. I scrambled for supplies, and got it ready. We had so much fun and the kids LOVED the results. Anyone that comes into me room raves over the kids' work and wants to know how we did it. ”

· Yvonne · Teacher
“I loved it. It allowed cross collaboration with P.E. and used a lot of sensory stimulation. Students were excited about the outcomes of the activity. I even had one student that didn't want to participate stayed late to work 1-1 and then went home to teach it to younger siblings that I did not get see. "Mr. Fuller, I did it at home and taught it to my sister."”

In this mini-lesson, K-5 students consider what would happen if their body didn't have bones. In the activity, Skeleton Hand, students combine science with art: they trace their hands, then add see-through bones to their picture, making their own skeleton hand. The activity includes an extension for older students to compare their hand bones to the bones of a mystery animal.
