Technology Foundation Standards for Students Students use technology resources for solving problems and making informed decisions.

Students employ technology in the development of strategies for solving problems in the real world.

Students must get the questions correct before proceeding to the next page.

The question checker tells which question is wrong and gives the student a second or fifth chance. Radioactive Decay Model site gives you a hands-on student activity to understand the decay curve of C-14.

Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object.

For carbon, there are a lot of C-12, a couple of C-13, and a few C-14 atoms.

When you average out all of the masses, you get a number that is a little bit higher than 12 (the weight of a C-12 atom).

Then students will analyze an article written about the C-14 dating of the Shroud of Turin and draw conclusions.

Although the results are definitive, they can be used to support either point of view.

Bromine (Br), at atomic number 35, has a greater variety of isotopes. There are two main isotopes at 79 and 81, which average out to the 79.90amu value. While it won't change the average atomic mass, scientists have made bromine isotopes with masses from 68 to 97. As you move to higher atomic numbers in the periodic table, you will probably find even more isotopes for each element.



Learn about different types of radiometric dating, such as carbon dating. Understand how decay and half life work to enable radiometric dating. Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object. Explain the concept of half-life.… continue reading »
