Hon Chemistry 11-8-19 Polymers

HON CHEMISTRY: Oh, my word! We finally finished the chapter! Have you had a chance to check out the Chapter 7 Stuff to Know sheet?

Also amazing – did you realize molecules could be that large? And so many of them! Don’t you think polymers are some pretty unique compounds? Let’s play with them next week!

Some items for contemplation: why are certain plastics recyclable and others not…and what about dishwasher and microwave safe?

Physics 11-8-19 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 Jackson & Matty, and thank you Danny! Awesome! I love, love, love watching you make physics come alive!

So….I started recording a little early and there’s probably about 10 minutes of Jackson and Matty and Danny jumping off the lab station, but then – vertical forces.

Chemistry 11-8-19 Binary Molecular Formulas

CHEMISTRY: Do you feel like you have letter and numbers swimming in your eyes? This is one of those times that paying attention to details is super, super important! Here’s the lecture from today on writing formulas and names for binary molecular compounds. Part of it’s really similar to what you learned to do last week for ionic compounds, but another part is totally different. Details!!

Make sure you keep everything straight. Do something that will organize all the information for you, so you won’t get confused. Also, don’t forget the lists you have to memorize – it’s getting larger and larger!! And practice, practice, practice!!!

Need extra practice? Another help session??
