Studying for the test should not be too stressful. We have time to review the test practice page in class before the test! Your classwork shows you know half life problems and nuclear equations pretty well. If you want more practice on those you can complete the "halfws" for extra credit (see paperclip on 10/24) or just try a problem from the PowerPoint called "Radioactivity and Half Life". (Click on the paperclip on Wed, 10/25).
Need more practice on nuclear equations? Try these multiple choice questions at sciencegeek.net
I'll be adding an oil drop experiment animation to the page later just for the curious.
Mole Day was great! Thank you for making great cards and sculptures!
TEST EXTRA CREDIT will be converting grams to moles and then atoms like #6 we studied in class today!
