Chemistry 2-17-21 Activity Series & Completing Chemical Equations Review

Posted on by

CHEMISTRY: Happy snow week! Here’s the lesson for Wednesday. It’s the LAST of the notes from chapter 8. At the end is a great review of completing and balancing equations. Also be sure and check the syllabus to find out about the optional homework assignment that will be great help if you’re having trouble predicting products of reactions.

So guess what happens when a gummy bear falls into a test tube of molten potassium chlorate?! Click on the video below to find out! Do you reckon that it’s a physical change or a chemical change? Why do you think?

Remember these steps when you are completing chemical equations: #1 – write the correct formulas; #2 – ask yourself what type of rxn it is; #3 – find the rule that applies and go for it! Don’t forget also that if you answer single replacement to #2 (or the synthesis or decomposition of a metal oxide!) you’d better check the activity series first!! Good luck!

Hon Chemistry 2-17-21 Structure of the Atom

Posted on by

HON CHEMISTRY: Happy snow week! Here’s the lesson for Wednesday! As you watch and take notes, follow the connections the scientists made as they discovered the structure of the atom. Do you think there could be anything smaller than protons, neutrons, and electrons? Hmmmmm……

Make sure you know the name of the scientists, the name of their experiments, be able to draw a diagram of their experiment, and describe how they interpreted the experimental results that led to their discoveries.

Here are some extra video clips to go with the lesson for today. They’ll help you review the different experiment that the guys like Thompson and Rutherford did. Click here for the video on the Cathode Ray Tube Experiment that Thompson did, and also for a little history on The Discovery of the Electron. Here’s the other one on The Discovery of the Nucleus.

By the way – do you think you could do what they did – figure out what something’s made of without seeing it?

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

Posted on by

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

Posted on by

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.

Physics 2-10-21 Angular Momentum & Newton’s Law of Universal Gravitation, Pt. 1

Posted on by

PHYSICS: Wait! There’s a fourth law? Yep – Newton’s law of universal gravitation! So when you jump off of something, the Earth moves, huh?

You’ve learned little g, now you know big G! Good job setting up the formulas, also make sure you can apply the concepts.

Ready to escape? We’ll tackle the rest of the applications of this law tomorrow!

Chemistry 2-10-21 Single Replacement Reactions & the Activity Series, Pt. 2

Posted on by

CHEMISTRY: Good job today on single replacement reactions! And great job using the activity series!

We’ve done 15 so far – how are you doing on memorizing them?! Careful though, don’t just memorize. 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!!

CHEMISTRY: What!?! You mean there aren’t little green people on lonely country roads? 😉

Great job applying the activity series to synthesis and decomposition reactions. As you practice, go back and check the activity series and your notes on the activity series!

Chemistry 2-8-21 Decomposition Reactions

Posted on by

CHEMISTRY: Great job with synthesis and decomposition reactions! Now can you use them? And how are you doing on memorizing them? Best way to learn them – practice!! Below are the lessons from Friday and today on synthesis and decomposition reactions.

HOMEWORK UPDATE: The page numbers for the homework are wrong. Always book homework will be the chapter review at the end of the chapter that we’re currently working on. We are on chapter 8, and I believe the homework starts on page 284. I think. Maybe. Check it out.
