For students, understanding the general architecture of the atom and the roles played by the main constituents of the atom in determining the properties of materials now becomes relevant.Having learned earlier that all the atoms of an element are identical and are different from those of all other elements, students now come up against the idea that, on the contrary, atoms of the same element can differ in important ways. 79.) In this lesson, students will be asked to consider the case of when Frosty the Snowman met his demise (began to melt).Written below is the case as it appears on The Case of the Melting Ice student sheet.The Case of the Melting Ice Frosty the Snowman lies melting in the funnels at your lab station.You can refer to How Carbon-14 Dating Works, from How Stuff Works, to help you answer the question.The following material has been taken from a sheet entitled Several Faulty Assumptions Are Used in all Radiometric Dating Methods.Make a data table and, at regular intervals (you decide how long), record the time on the clock and the volume of water in the graduated cylinder.Stop after about 30 minutes, unless Frosty has completely melted earlier.

Empty the graduated cylinders between classes if the volume is more than about 25 ml.The second lesson, Radioactive Decay: A Sweet Simulation of Half-life, introduces the idea of half-life.By the end of the 8th grade, students should know that all matter is made up of atoms, which are far too small to see directly through a microscope.(This page has been archived and is found on the Internet Archive.) In addition to using answers to students' Analysis questions and their graphs for evaluation, consider having them respond to the following in their science journals or as a homework essay: Pretend you are on a month-long field trip to dig for artifacts that might have been left from the pre-colonial period in the United States.Write a letter to a friend explaining what radiocarbon dating is.

For the laboratory portion of this lesson, you will have to set up the ring stands, rings, funnels, and graduated cylinders.
