Bones are hard because they contain calcium. Calcium is a mineral contained in human and animal bones.
Try this experiment to see if we can bend a chicken bone in half.
You will need:
*Drumstick chicken bone
You will need to:
*Clean the chicken bone. Make sure all of the meat is gone.
*Put the bone in a jar. Pour enough vinegar to cover it.
*Put the lid on the jar for three days.
*After the third day, take the bone out of the vinegar.
*Try bending the bone. Does it feel rubbery? What happened?
Science behind the activity: The vinegar is a mild acid. It dissolves the calcium in the bone. This leaves the bone soft and rubbery.
