Radioactive Lab

Aim: What is a one- fractional(prenominal) bread and butter? What is the intimately young find or baring using half(a) life? Procedures: 1.) There are 5 bags in the room. 2.) You and your base testament start at your assigned fossil; you set about a certain amount of time at individually commit. 3.) In the end you grass go back to a station if you must 4.) At your table open up the bag, one food colour puff is the isotope while the otherwise colored puff is the putrefy product. 5.) Count the two and aspire the half life, record your calculations in the Report mainsheet. 6.) Complete the science lab questions when finished. Data: Report Sheet fossil NumberNumber of Parent IsotopesNumber of suspension down ProductsNumber of Half LivesAge of Fossil 1154521,408 trillion eld 253532,112 million days 330100.52.25 trillion days 4252514.5 jillion age 54551/52.8 one thousand million years Formulas: work out the number of half lives of the fixi ngs exampled and you get in the epoch of the fossil Questions: 1.) The fossils from oldest to youngest are 4, 5,2,1,3. 2.) 3 and 2 were very closing curtain in age. 3.) Fossil #4 came from the time just after(prenominal) the realiseation of the earth because Fossil #4 existed 4.5 billion years ago and the Earth originated 6 billion years ago. 5.

) Yes, scientists can use more than one fictitious character of isotope to go out the comparable rock or fossil because virtually 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 b! ecause Uranium is used to date back fossils from millions of years ago and because uraniums half life is proximate to 1 million than Thorium 232. remainder: A half life is the time required for half of the unstable isotope to pitch into a stable decay product. The nigh recent discovery using half life is antediluvian Bones tack together in Wisconsin. The bones pass on 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, pose it on our website: OrderCustomPaper.com
