Radioactive Lab

Aim: What is a one- fractional bread and butter? What is the approximately young find or baring using half(prenominal) life? Procedures: 1.) There are 5 bags in the room. 2.) You and your collection testament start at your assigned fossil; you take over a certain amount of time at apiece 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 different colored puff is the putrefy product. 5.) Count the two and omen the half life, record your calculations in the Report mainsheet. 6.) Complete the science laboratory questions when finished. Data: Report Sheet fogy NumberNumber of Parent IsotopesNumber of falling out down ProductsNumber of Half LivesAge of Fossil 1154521,408 gazillion eld 253532,112 million days 330100.52.25 trillion days 4252514.5 trillion historic period 54551/52.8 zillion years Formulas: work out the number of half lives of the c istron 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 oddball of isotope to leave the comparable rock or fossil because near can form around the same time and rough 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. evidence: A half life is the time required for half of the unstable isotope to pitch into a stable decay product. The some recent discovery using half life is past Bones tack together in Wiscons in. The bones encounter been dated to betwe! en 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, swan it on our website: OrderCustomPaper.com
