Hon Chemistry 4-18-19 Testing For Gases Lab

HON CHEMISTRY: Here’s a very, very short look at the positive tests for carbon dioxide, oxygen, and hydrogen gases for the experiment: Making and Testing for Gases. We’ll do the lab on Tuesday when we get back from Easter break. Make sure you have shown me the three balanced equations you’ll need for the experiment. I think you’ll have lots of fun with this one. 🙂

Physics 4-17-19 Harmonics & Beats

PHYSICS: So why do instruments that are playing the same note sound so different? Here’s our discussion of harmonics and beats.

Speaking of discussion – what did you think about the Tacoma Narrows Bridge? Any ideas on an explanation? Here’s a link, if you’d like to see it again: Tacoma Narrows Bridge

Physics 4-16-19 Sound Intensity and Resonance

PHYSICS: Great music today! And great discussion of intensity and resonance! Were you okay with the problems?

Couple of items to apply for further contemplation – so how does the whole hearing thing work? I mean, I know the little bones in your ear move, but why? Is resonance involved? Great item for application/discussion!

Hon Chemistry 4-15-19 Double Replacement & Combustion Reactions

HON CHEMISTRY: You realize what we did? We finished all 17 types of reactions today!

Careful when you work tonight’s homework! For all single replacement reactions and reactions involving forming or decomposing oxide, be sure and refer to the Activity Series. Yes, you will get to memorize it, but for the big test, not for the coming up quiz!

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!)

Physics 4-12-19 Wave Interactions

PHYSICS: Cool thing, standing waves! How’d you like making waves with slinkies? Are you okay with constructive and destructive interference?

Here’s the slinky activity for today. Stretch the slinky a pretty good length between you and your partner, but not enough to overstretch the slinky. Below that, the discussion of wave interactions.

Hon Chemistry 4-12-19 Single Replacement Reactions & the Activity Series

HON CHEMISTRY: Moving right along with the 17 types of chemical reactions, here are the single replacement reactions – and you also got a head start on the activity series!

This makes 15 reactions so far, and we’ll do the rest on Monday. Careful though, memorize, 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!!
