Dating science fair projects

One of the oldest and largest Fairs in the country, DVSF embraces a philosophy is that students learn science by doing science.In the process, students learn how to think and develop critical problem solving skills that they will need for careers, college and citizenship.So, if you had a fossil that had 10 percent carbon-14 compared to a living sample, then that fossil would be: t = [ ln (0.10) / (-0.693) ] x 5,700 years t = [ (-2.303) / (-0.693) ] x 5,700 years t = [ 3.323 ] x 5,700 years t = 18,940 years old Math Skills Using natural logs (loge or ln): Carrying all numbers to 5 significant figures, ln 30 = 3.4012 is equivalent to e3.4012 = 30 or 2.71833.4012 = 30 A formula to calculate how old a sample is by carbon-14 dating is: t = [ ln (Nf/No) / (-0.693) ] x t1/2 where ln is the natural logarithm, Nf/No is the percent of carbon-14 in the sample compared to the amount in living tissue, and t1/2 is the half-life of carbon-14 (5,700 years).from Pennsylvania, Southern New Jersey and Delaware, make new discoveries that could change their lives forever as they participate in the Delaware Valley Science Fairs (DVSF).Nearly million in scholarship and prize money is awarded to students winners.DVSF takes top high-school winners to the Intel International Science and Engineering Fair (ISEF) competition in May to compete for more than million in scholarships and awards.
