Module 9: Earth’s HistoryTopic 2 Application: Radioactive Dating Scientific Investigation ReportTitleRadioactive DatingHypothesisIf the percentage of an isotope in an object is high, then the half life will be a longerlength of time and the object will be older. Using theProcedure and Data Collectionsection below, read through the procedural information forthis scientific investigation. Based on your understanding of the procedure, develop your own hypotheseswhich describe your expected results. Specifically, why are different elements are used for datingdifferent objects? Record these hypotheses below.DataHalf-LifeIn the blank space provided, record your observations for the half-life of carbon-14 and uranium-238.Carbon-14Uranium-238Decay Rates1
