Our next Unit in science deals with the different body systems. We will
begin learning about the skeletal system first. The students will study
several specific bones, the joints, the overall importance and functions of
the skeleton as well as how we can best take care of it.
Fun Facts:
Skeletal System!
Our bone is six times stronger than steel if both are of the same weight.
The size of the smallest bone is equivalent to the size of a rice grain.
Of the 206 bones in the skeletal system, 52 of them make both our feet.
The human hand has 27 bones; your face has 14!
The longest bone in your body? Your thigh bone, the femur -- it's about 1/4
of your height. The smallest is the stirrup bone in the ear which can
measure 1/10 of an inch.
Did you know that humans and giraffes have the same number of bones in their
necks? Giraffe neck vertebrae are just much, much longer!
You have over 230 moveable and semi-moveable joints in your body. http://www.ipl.org/div/kidspace/browse/hea0000/
