We have rocks from the Moon (brought back), meteorites, and rocks that we know came from Mars.

We can then use radioactive age dating in order to date the ages of the surfaces (when the rocks first formed, i.e. We also have meteorites from asteroids and can date them, too.

For others, all we are doing is getting a relative age, using things like the formation of craters and other features on a surface.

They then gather the radioactive, or M side up M&Ms, put them back in the container, and then pour them out again. and continue this process until all M&Ms are stable, or M side down.

During each trial, students record the number of radioactive parent isotopes and record this in a data table.

Wiens has a Ph D in Physics, with a minor in Geology.

His Ph D thesis was on isotope ratios in meteorites, including surface exposure dating.
