Day 7 Recap
Honors G: thanks for bearing with me during my rant about "theory" vs. scientific theory...it is a very important distinction though. Today we covered three of the four Dalton Postulates on Atoms and Matter; we DREW examples showing the physical meaning of each postulate.
Honors D: we reviewed and then finished the Four Dalton Postulates and drew examples of each; we then discussed/explained the Law of Constant/Definite Composition for any compound; we also began to discuss the Law of Multiple Proportions- I will give you a good example of that tomorrow (same for G period).
We discussed the crucial distinction between accuracy and precision and also how to record lab data based on the precision of the lab equipment. Tomorrow, we will make and record some measurements also.
Regents: we did a couple of atomic mass calculations and then we used the same formula to calculate the percent abundance of each isotope of an element (our problems will be limited to two isotopes when we calculate percent abundance).
Look to the website for worksheets. IMPORTANT: if there is a section of a worksheet that we did not yet cover in class, just skip that section until we do cover the material in class.
Last call for Orange Review Book checks. Thanks.
AP: describing, graphing, and explaining the gas laws. Tomorrow, we get into the gas law equations and permutations thereof.
