Human Skeleton Set

This is a new type of set for me! I’ve made 6 unique sized blocks, featuring some main bones in the human skeletal system. 
The skull is 80mm x 70mm
The Torso is 80mm x 100mm
And each arm and leg is 55mm x 170mm
Here I’ve filled the solid oak boards with white sand. 
I also sprinkled the sand on my light panel then gently pushed and wiggled the blocks in the sand so that when I pulled the block up it left a sand impression. It looked especially cool on the light panel. 
You could also stamp them into playdough then cut out to build a skeleton. Or you could take crayon rubbings and then cut out to build a skeleton. 
You could also use them for a science activity to name some main bones in the body. 
So many possibilities with this one set.
