Chicken Bone In Acid Experiment

While I was away sick my science class did a science experiment using chicken bones and

various liquids. Today two weeks passed since we soaked the bones so we took them out

and reflected on them. Here is my learning and reflections.

What is bone made of?

Bones are mostly made of collagen but also have calcium keeping our bones strong

Aim  To investigate the effect of acid, water and cola on chicken bone.

Method

• Collect 4 chicken bones
  
  
• Weigh each bone
  
  
• Put bones in individual containers
  
  
• Add 1 of various liquids to the container and chicken
  
  
• Store for two weeks and reflect on the differences
  
  

Results

	Bone in Water	Bone in Acid	Bone in Coca Cola
Observation	Smells very bad	Bendy/Elasticity	Turned Black and Hard
Mass (g) Before	8 grams	9 grams	8 grams
Mass (g) After	12 grams	8.8 grams	9.8 grams
Difference in Mass	4 grams	- .2 grams	1.8 grams
Changes	Water absorbed into the bone causing it to become softer. The bacteria that grew while it was in the water for 2 weeks started to create and odour.	The acid disintegrated several parts on the bone and absorbed into the bone making it bendier, How ever the acid did not form an odour.	The bones soaked in Cola turned black throughout the two weeks. Its texture and smell didn’t change. We plan to re-do the cola experiment as the cola was old and it should have been bendy.

Conclusion

The bones were not majorly affected after sitting in various liquids for 2 weeks however

small changes in colour, elasticity and smell occured.
