Chemistry 11-16-20 Writing Chemical Formulas

CHEMISTRY: Great job today writing chemical formulas! The key to getting good at it – practice, practice, practice!!

Check Evernote for your graded lab. The Wi-fi here at school kept blocking the initial set-up, but check at home. Go to your Gmail and find an invitation from me to share a notebook. Click on it, and then go to Evernote and click on Shared with Me. (You can find it under one of the menues). In a sec you should see a file from me that you can add, and then view. It may work better the first time on your computer than your phone. Try that.

Hon Chemistry 11-13-20 Using Chemical Formulas

HON CHEMISTRY: So the little mole turns out to be a pretty big deal – and a very handy tool!!

Great job today! Here’s discussion on formula mass and molar mass, and then using molar mass and Avogadro’s number as a conversion factor. You’ve got a couple of great tools – so now think through the problems and go forth and conquer!! Be sure and practice them so you don’t forget!

Chemistry 11-13-20 Naming Chemical Formulas

CHEMISTRY: Great job learning to name binary ionic compounds!

Speaking of formulas, what is your plan for all the memorization in this chapter? Word of warning – don’t wait to the last minute!!

Super important – the secret for the next few days and this entire chapter is DON’T GET BEHIND! Keep up with me and practice, practice, practice!

Physics 11-13-20 A Look Back at Chapter 4 Concepts & Help Session

PHYSICS: Leaves gracefully falling – can you apply concepts from this chapter to explain? Practice, practice practice the problems, but don’t forget the conceptual stuff! Here’s a short look (from last year) at some additional concepts and below that the help session from yesterday morning.

How do parachutes work? What causes whiplash and how do seat belts work? If you get a chance, watch the Julius Sumner Miller videos on Newton’s 2nd law and 3rd law on You Tube. And also, here’s the link to the video clip I showed you on terminal velocity and the Physics of Skydiving I think they’ll all help a lot with the conceptual information

Thursday Morning Help Session

Hon Chemistry 11-12-20 Moles, Molar Mass & Avogadro’s Number

HON CHEMISTRY: So….you think if his work helped us understand something as significant as the number of something in a mole they might name something after him? They did! Go figure! Another name for the number of anything in a mole is Avogadro’s Number. That would be how many?

You caught on super fast today! Remember, it’s all in terms of one mole. The mass of one mole, the molar mass, is the average atomic mass of the element in grams (periodic table). And the number of atoms in one mole is …. well you know that. Speaking of moles, isn’t he cute? Well, beauty being in the eye of the beholder and all. Hmmmm………

PHYSICS 11-11-20 Vertical Fish Forces & Forces with Pulleys and Friction

PHYSICS: Not sure if you’d ever find a fish on an elevator, but you sure could treat the problem like it was! Here a look at the fish on a line problem, and then, a different take on forces – an application of horizontal forces, vertical forces, friction, all at once!

Wow! Amazing job solving these problems – can you now go see if you can solve them by yourself?

Help session tomorrow, 7:30h A.M.

Hon Chemistry 11-10-20 Oxidation Numbers

HON CHEMISTRY: So how are the chemical formulas and chemical names coming? With oxidation numbers, you now have a few guidelines to help polish up what you already know!

Oxidation rules! We’ve really already been using oxidation numbers, you just didn’t know it! 🙂

Physics 11-10-20 Net Vertical Force

PHYSICS: Great start with net vertical force! Don’t you think it’s the same as horizontal – just turned 90 degrees? And incredible demonstrations of some important concepts!

Thank you Wilson & Madison, and Caroline! Awesome! I love, love, love watching you make physics come alive!

 

Physics 11-9-20 Friction & Forces on an Incline Problems – Take 2

PHYSICS: Boxes and block, all slipping and sliding… Is it starting to make a little more sense? Here’s our look at #40 and #52 – taking it a step further.

You’re getting it…keep sledding and watch out for net forces!
