Aim: What is a one-half bread and butter? What is the most young find or baring using half life?
Procedures:
1.) There are 5 bags in the room.
2.) You and your group testament start at your assigned fossil; you have a certain amount of time at each 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 other colored puff is the putrefy product.
5.) Count the two and calculate the half life, record your calculations in the Report mainsheet.
6.) Complete the lab questions when finished.
Data:
Report Sheet
Fossil NumberNumber of Parent IsotopesNumber of break down ProductsNumber of Half LivesAge of Fossil
1154521,408 million eld
253532,112 million days
330100.52.25 trillion days
4252514.5 billion years
54551/52.8 billion years
Formulas: work out the number of half lives of the element 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 type of isotope to date the comparable rock or fossil because some can form around the same time and some 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 Ancient Bones tack together in Wisconsin. The bones have 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, order it on our website: Orderessay
