At your table open up the bag, one food colour puff is the isotope while the new(prenominal) colored puff is the putrefy product. 5.) Count the two and target the half life, record your calculations in the Report mainsheet. 6.) Complete the science lab questions when finished. Data: Report Sheet dodo NumberNumber of Parent IsotopesNumber of mark off down ProductsNumber of Half LivesAge of Fossil 1154521,408 cardinal eld 253532,112 million days 330100.52.25 trillion days 4252514.5 trillion years 54551/52.8 one thousand thousand years Formulas: work out the number of half lives of the partic le exampled and you get in the epoch of the fossil Questions: 1.)

) Yes, scientists can use more than one font of isotope to pick up the comparable rock or fossil because more or less can form around the same time and well-nigh cant. 6.) I would use Uranium 235 to date a sample that was estimated to be about 1 million years old. I would use Uranium 235 because Uraniu! m is used to date back fossils from millions of years ago and because uraniums half life is proximate to 1 million than Thorium 232. result: A half life is the time required for half of the unstable isotope to pitch into a stable decay product. The or so recent discovery using half life is superannuated Bones tack together in Wisconsin. The bones defy been dated to between 5,600 and 5,800 years old using half life. They were discovered in unsanded Hope Cave at Cherney Maribel Caves County Park in...If you want to get a full essay, post it on our website: OrderCustomPaper.com
