The first lesson, Isotopes of Pennies, deals with isotopes and atomic mass.
The second lesson, Radioactive Decay: A Sweet Simulation of Half-life, introduces the idea of half-life.
Atoms may stick together in well-defined molecules or they could be packed together in large arrays.
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.
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.
For the laboratory portion of this lesson, you will have to set up the ring stands, rings, funnels, and graduated cylinders.
The element carbon is an essential element in all living matter.
Though they are very tiny, polonium radiohalos have a huge message that cannot be ignored.
Many geologists claim that radiometric “clocks” show rocks to be millions of years old.
However, to read any clock accurately we must know where the clock was set at the beginning.
Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object.
I appreciate you sharing all these helps and resources.
They point to a catastrophic origin for granites, consistent with the biblical timeframe for earth history and God’s judgment during the Flood.
