Isotopes are important to geologists because each radioactive element decays at a constant rate, which is unique to that element.
However, sometimes it is useful to record macros in relative mode. If you don't know how to record a macro, we highly recommend you to read this example first.
Once they are able to manipulate the cards into the correct sequence, they are asked to do a similar sequencing activity using fossil pictures printed on "rock layer" cards.
Sequencing the rock layers will show students how paleontologists use fossils to give relative dates to rock strata.
The atoms of some chemical elements have different forms, called isotopes.
The site also provides fact sheets on the age of the Earth and isochron dating.
As a member, you'll also get unlimited access to over 55,000 lessons in math, English, science, history, and more.
First, select any single cell (for example, cell B8).
Result: Excel places the words relative to the initial selected cell.
Select any other cell (for example, cell D4) and run the recorded macro.
