Forensic carbon 14 dating problems
Have each group share their charts with the class and fill in any missing pieces of evidence.
Also, the atomic bomb testing around caused a rise in neutrons, which increased carbon concentrations. After 5, years, the amount of carbon 14 left in the body is half of the original amount.
The second faulty assumption is that the rate of carbon formation has remained constant over the years. Right now believe it or not your body has a natural amount of carbon in it as do animals and plants.
Due to nuke testing over 60 years ago, forensic investigators can now use carbon dating — a method normally used to age ancient fossils — to find the birth and death dates of recent unidentified human remains. In fact, changing the environments surrounding the samples can alter decay rates. We tend to see what we want to see, and explain away unwanted data.
This would have resulted in an enormous amount of carbon being released into the oceans and atmosphere. A natural product from this constant interaction is radioactive carbon, or carbon
