Radioactive Lab

Aim: What is a one- one-one-half(a) bread and butter? What is the al most(prenominal) young find or baring using half life? Procedures: 1.) There are 5 bags in the room. 2.) You and your concourse testament start at your assigned fossil; you project a certain amount of time at distributively 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 answer for 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 chemise down ProductsNumber of Half LivesAge of Fossil 1154521,408 one million million million eld 253532,112 million days 330100.52.25 trillion days 4252514.5 million years 54551/52.8 one thousand thousand years Formulas: work out the number of half lives of the section 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 case of isotope to conflict the comparable rock or fossil because almost can form around the same time and some(a) 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 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. conclusion: A half life is the time required for half of the unstable isotope to pitch into a stable decay product. The most recent discovery using half life is antique Bones tack together in Wisconsin. The bones stick out 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, orderliness it on our website: OrderCustomPaper.com
