Physics 2-12-21 Newton’s Law of Universal Gravitation, Pt. 2 & Tides

PHYSICS: So would you ever like to escape? Here’s our look at another of Newton’s Law of Universal Gravitation…… and to continue, tides.

Also, here’s a link to Paul Hewitt’s explanation of ocean tides – and there are lots of others! Hewitt Drew-It Ocean Tides

Hon Chemistry 2-12-21 Intro to Atomic Theory

HON CHEMISTRY: So how do you feel about being made from earth, air, water, and fire? Here’s the intro we did on how we ended up with the atomic theory. Had you ever heard of Lavosier, Proust, and Dalton?

Pretty impressive little theory that Dalton came up with, huh? Were you surprised as you made comparisons with the Modern Atomic Theory? Could you now take it a step further and show connections between the three laws we discussed today and Dalton’s atomic theory?

Chemistry 2-12-21 Double Replacement & Combustion Reactions

CHEMISTRY: You realize what we did? We finished all 17 types of reactions today! Have you been practicing using them?

HOMEWORK UPDATE: Your homework for the weekend is the Physics Classroom activity that’s listed on the syllabus. It is due Tuesday morning, 8:00 A.M.

Are you working on memorizing all 17 types of reactions?! But don’t just memorize them. Make sure you can apply them as well. When you start to work any equation, first determine what type of reaction it is, then figure out what rule applies and follow it to determine the products. I believe in you! You can do it!! (and yes, I realize I am repeating myself, but I do and you can!)

Hon Chemistry 2-9-21 and 2-12-21 Intro to Atomic Theory

HON CHEMISTRY: For such a short lesson, it sure did take us a while to finish! Here’s the last of our discussion of modern atomic theory vs. Dalton’s atomic theory – well, actually a vodcast that has everything in one place. Your homework is only the homework that goes with this lesson. When we get back to school, we’ll do the Activity: Model of an Atom.
