Engage students in science exploration from the inside out with this classroom science supply! We've printed 16 beautiful animal images on the front of plastic sheets. Examine the photos and then place them on a light table or in a window to reveal the skeletal system of the animals! Flip the cards over to get a better look at the skeleton. This is a fun science lesson for children in all grades and an excellent way to introduce them to animals and anatomy.
