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. The images are protected with a special, scratch-resistant coating. Examine the photos and then place them on a light table or in a window to reveal the skeletal system of the animals! This is a fun science lesson for children in all grades and an excellent way to introduce them to animals and anatomy. Flip the cards over to get a better look at the skeleton. Compare and contrast the image of the human to the walrus, giraffe, snake, owl, etc. 16 animal x-rays including 2 human images. Cards are 8.5" x 11" (22cm x 28cm). Includes teacher guide.
