CHEMISTRY: So ordinarily it looks like just any old hunk of rock, but this is a picture of uranium ore under UV light. Pretty cool, huh?!? Here’s the lecture from Thursday on the properties of radioactive nuclides and the types of radioactive decay.
Hey, great job learning to write nuclear equations today! Don’t forget to memorize the nuclear symbols for alpha particles, beta particles (electrons), positrons, neutrons, and protons. I don’t think it will be nearly as bad as polyatomic ions! 🙂
Have any of you decided you want to get a head start on the half-life simulation lab? Don’t let it stress you out! It’s one of easiest labs you’ve done. But it does require that you READ the instructions on the syllabus and the website. If there is something you still don’t understand, make sure you ask me, I’ll be glad to help! And speaking of half-life, let’s calculate it tomorrow. Calculators ready!
This chapter is going to be very interesting.
I am glad to be back in your class Ms.Skinner!
I think this is one of the most interesting chapters we’ve read so far.
Is there going to be to parts to the lab we are doing?
i cant wait to learn more about radioactivity
Learning how to do those half-life problems today where kinda confusing but I think I understand it now!
I think learning about radioactivity is intresting.
I know that I really need to study the half-life problems!
This chapter is very interesting. It’s cool that we are learning nuclear equations.
Will we be getting a study suggestions sheet for this chapter?
What were doing right now in chemistry is so interesting and i think im actually getting it!!:)
When is the test for this chapter?
Hey! Well it’s good to be back in 6th period. I’ve found this past weeks lesson interesting even though the whole half-life idea has given me a bit of trouble. Hopefully like you said the practicing will definately help.
Never thought I’d be learning about radioactive decay and half-lives in school. Really glad we are. Thank you!
Ms. Skinner- what did I miss in class today?
I didn’t understand this at first, but now I get it.
I really liked learning about radioactivity this week!
