Chemistry 11-21-25 Moles, Mass, Atoms & Avogadro

CHEMISTRY: So… how big a bucket do you think we’d need to hold a mole of frogs? 🙂

Nope, not the furry brown creature that burrows underground, it’s a whole different thing! Here’s our discussion from Thursday on moles, mass, and Avogadro’s number. I still say he has a cool name… 🙂

HOMEWORK INFO: Do all the parts on the homework except only do b & c on the problems.

Hon Chemistry 11-21-25 Types of Chemical Reactions

HON CHEMISTRY: Okay, maybe balancing equations isn’t exactly like this, but…..

Here are the notes from today on the types of chemical reactions and then a little work with combustion reactions at the end. Good stuff!

UPDATE! Be sure and check the updated syllabus for what we did today and new assignment due dates.

Hon Chemistry 11-20-25 Describing Chemical Reactions

HON CHEMISTRY: So tell me again – how do you know if a chemical reaction has occurred? And how could you record that for someone? Here’s the lesson from today on writing balanced chemical equations.

Here’s another hint – it’s not necessarily a good idea to try to make your own blue flame thrower! Click here to watch the Periodic Videos Blue Flame Thrower Video

Hon Physics 11-19-25 Conservation of Energy & Pendulums, Pt 2

PHYSICS: Here’s our quick look look again at pendulums and the conservation of energy in problems. Be sure and take note of the nice new formula that helps you find the height of a pendulum, and be just as careful when you start playing around with the conservation of mechanical energy formula!

Physics 11-18-25 Work Energy Theorem, Pt. 2 & Intro to Conserv of Energy

PHYSICS: See?! I wasn’t kidding about the balancing rocks movement!

Great job today on making connections between work and energy with the conservation of energy! Don’t forget about friction! We’ll pick it up again tomorrow.

Chemistry 11-17-25 Oxidation Numbers & Molar Mass Review

CHEMISTRY: So how do you know if you really know something? Here’s one way – can you explain it to someone else? Here’s our review of oxidation numbers for compounds and polyatomic ions, and then we did a quick review of formula mass and molar mass.

Now to see if you really know it! The activities for today are on Snorkl. You’ll be answering and explaining three activities. You must have both audio recording and handwritten answers in all three activities. If you were absent today, the code for your class is at the end of the vodcast. Text me if you have questions!

Hon Chemistry 11-17-25 Chapter 7 Test Overview

HONORS CHEMISTRY: God bless you as you study for the test! Here’s our overview of the test from today.

Have you been using the “Chapter 7 Stuff to Know & Know How to Do” sheet? It’s a great way to get organized in studying for the test. I know it seems like a lot, but you can do it!

First priority – make sure that you have memorized EVERYTHING. Then, go to The Physics Classroom and/or sciencegeek.net and make sure you can write and name chemical formulas. Practice, practice, practice!!! Then start practicing the different kinds of problems – do at least three of each one of them. And also try those on sciencegeek.net. That’s always some good practice. God bless – I’ll be praying for you!

Physics 11-17-25 Work & Energy, Pt. 1

PHYSICS: Funny thing about words, all this work you thought you’d been doing, was it work after all?

Great job today on making connections between work and energy! I think you’ll like using the work-energy theorem, it’ll save you some time and a couple of steps. Don’t forget about friction!

Chemistry 11-14-25 Formula Mass & Molar Mass

CHEMISTRY: Now that you’ve learned to write and name chemical formulas, it time to take it to the next level and learn to use chemical formulas as a tool. Woohoo!!

Great job today with formula mass and molar mass! Be sure and show your work – and don’t forget to include the units. Super short lesson, but very important for the future!

Hon Chemistry 11-14-25 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? How about some applications?

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