4-11

Today in class we had a practice quiz and went over answers.
We also got out geiger meters, found out how they worked, and experimented a bit with radioactive samples.
Tomorrow we'll have an official lab on half-lives.


ALSO, I'm looking for volunteers to research and present to class. 5 minutes are offered, on the topics of:
How a geiger tube works
Nuclear Fusion - how it gives us energy
Nuclear Fission - how it gives us energy
I'll take one volunteer per class. Present on Friday if you volunteer. This counts as an optional assignment as well, and will accept one person per topic, per class period. First come, first serve.
