In this inquiry-based exploration students are asked to discover the nature of the mutation in a yeast strain by designing and carrying out their own experiments.
Students are provided with a conundrum: the same mutant yeast strain can grow on one type of media plate but not another.
Richter Magnitude is an estimate of the amount of energy released during and earthquake.
Upon completion of this activity you will be given the opportunity to receive a personalized Certificate as a "Virtual Seismologist." In order to get this certificate, you must make careful measurements throughout the activity.
Radiocarbon Dating: The radiocarbon dating method was developed in the 1940's by Willard F.
Libby and a team of scientists at the University of Chicago.
This activity also includes a C-14 option for once-living materials that are less than 50,000 years old. Radioactive Isotopes - the "Clocks in Rocks": Numerical and Relative Ages for Rocks.
A numerical (or "absolute") age is a specific number of years, like 150 million years ago.
Additionally, you will be required to determine the Richter Magnitude of that quake from the same recordings.It has been tested on Netscape Communicator 4.05 and Microsoft Internet Explorer 4.01 for both Windows 95/98/NT and Mac OS 8.1 on the Power PC.Minimum memory requirements are not known at this time.You must use a browser with Java and it must be Java enabled.Virtual Dating works best with Netscape Communicator 4 or Microsoft Internet Explorer 4 with Java Script enabled.
A relative age simply states whether one rock formation is older or younger than another formation.
