There were no eyewitnesses, but there are several suspects. You need to determine the exact time at which Frosty was put into the funnels to melt away, leaving no trace.

On a separate sheet of paper, immediately record the volume of Frosty's melted remains (water) in your graduated cylinder and note the time on the clock.

This lesson is the third in a three-part series about the nucleus, isotopes, and radioactive decay.

The first lesson, Isotopes of Pennies, deals with isotopes and atomic mass.

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

Fill the funnels with ice before the students arrive in the classroom.

It is incorporated into the carbon cycle, so that all living things, including you, contain radioactive carbon-14.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).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.
