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 may group them in any size group, but working in pairs is optimal for this exercise.
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).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.Living things have about 15 disintegrations per minute per gram of carbon.
Because living things constantly interchange carbon atoms, the amount of carbon-14 remains constant, but when organisms die, no new carbon-14 enters the organism.
You can continue to fill the funnels as different classes arrive.
