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.
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).Students should complete the Analysis section of the lab sheet, which will be used as part of their assessment.Advise students to read through the case first so that they understand what they should do.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.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(This page has been archived and is found on the Internet Archive.)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.
The exercise they will go through of working backwards from measurements to age should help them understand how scientists use carbon dating to try to determine the age of fossils and other materials.
To be able to do this lesson and understand the idea of half-life, students should understand ratios and the multiplication of fractions, and be somewhat comfortable with probability.
This lesson is the third in a three-part series about the nucleus, isotopes, and radioactive decay.
