Practice exercises on radiometric dating
Fill the funnels with ice before the students arrive in the classroom.
You can continue to fill the funnels as different classes arrive.

For the laboratory portion of this lesson, you will have to set up the ring stands, rings, funnels, and graduated cylinders.
By measuring how much carbon is left in a sample as well as its radioactivity, we can calculate when the organism died. In this activity, you will work backwards to solve a puzzle, much like scientists work backwards to find the time that an organism died." Procedure Give each student a copy of The Case of the Melting Ice student sheet.
You may group them in any size group, but working in pairs is optimal for this exercise.
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.
They should also understand that the atoms of any element are alike but are different from atoms of other elements.
