What’s it about?

You might know that ‘calcium’ is very important for healthy bone growth in humans and in animals. What is lesser known is that bones are also full of ‘protein’ fibres, which are equally important than calcium for healthy bone growth. Study what happens when bones is depleted of its proteins in the following science experiment:

Topics covered

Protein, Calcium

What will I need?

  • 2x GLASS JARS
  • 2x CHICKEN BONES (CLEANED)
  • TAP WATER
  • BLEACH
  • SCISSORS

Procedure (Method)

How does it work?

Unfortunately, this section is only available in the e-book version of the project.

This science experiment works because when a fresh chicken bone, which is rich in proteins, is submerged in bleach, a chemical reaction takes place that breaks down most of the ‘proteins’ and tissues contained in the bone. All that remains after a while is the ‘calcium’ and other minerals which weakens the bone and makes it ‘brittle’
