Hon Chemistry 5-16-17 pH & Indicators

HON CHEMISTRY – Who knew – chemistry and art!! Great work using pH with electrolysis today!

How are you doing on calculating pH? Acids mean H30+ ions and pH, bases mean OH- ions and pOH. Get the pH of an acid straight from the concentration of the acid. Get the pH of a base by first finding the pOH straight from the concentration of the base and then subtracting that from 14. No problem!! So how do you think someone would use pH?

Don’t forget about learning those indicator colors I told you about. Can you think of anything else that might be a natural indicator? What about tea? Have you noticed how it changes to a lighter shade when you add lemon?

Chemistry 5-3-17 Activity Series, Double Replacement & Combustion Rxns

CHEMISTRY: Wow! Can you believe we finished all 17! Here’s the lecture on the rest of the activity series and double replacement and combustion reactions. Now that you’ve got everything on paper, it’s time to practice!

Need some extra help? Help session? Let me know and I’ll be glad to schedule one!

Chemistry 5-2-17 Single Replacement Reactions & the Activity Series, Pt. 1

CHEMISTRY: Good job today on single replacement reactions! And today you got a head start on the activity series. Good job!

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!!

Hon Chemistry 5-2-17 Kinetic Molecular Theory & Pressure

HON CHEMISTRY: Who knew there could be so much to learn about gases! And we’ve only just begun! Here’s the lecture on the kinetic molecular theory. Remember, don’t just know, know why!

Chemistry 4-24-17 Synthesis & Decomposition Reactions

CHEMISTRY: Wow! So that’s where the pretty light comes from! Great job on catching up with synthesis and learning decomposition reactions.

I know we actually did them on two different days, but I thought it might be helpful to have both in one vodcast. Now go forth and practice what you learned! (The balancing equations part, not the playing with magnesium part!)

Lost in La Mer du Labrador – The Last Weekend!!!

It’s you last weekend to work, so how’s it going with the Lost in La Mer du Labrador project? Remember, first and foremost this is a CHEMISTRY project. You must talk about all 23 items – why they would be good to use or why you would not want to use them. NEVER ever say, I had no use for the item.

Here are a few other things to remember – a long list to review, but very important, so READ IT ALL! TWICE!

1. Save, save, save, save, save, save, save, to several different places because your computer wants to eat your project!! Email your latest copy to yourself – label it with the date so you’ll know it’s the latest one, or put it in Google Drive or use a flash drive, or Google Dropbox – and use the date thing when u save it. And printing out the latest copy is also a great idea!

2. Your printer and the printer at your parents’ job will die/ run out of ink/ jam/ run out of paper/ explode, etc., so don’t wait until the last minute to print things out. And save, save, save, save, save, save, save, to several different places because your computer wants to eat your project!!

3. Make sure you make printed copies of the sources each source you use. Copy the first page and the page that you use, and highlight the portions that you use. Staple multiple pages.

4. Your copied sources should be in the order that the items they refer to occur in your paper. If you have the same source for different items, you must have different copies.

5. Your paper must be in general manuscript form – typed, double spaced, last name and page number on each page, etc. Each section of your paper should start on a new page.

6. The first time (or even every time is okay) you mention one of the main 23 items in your paper, highlight it so it will be easy to see. If you use the item again later in your journal for a different reason, highlight it again.

7. Always use the title of a website article if it has one or the name of the organization that produced the website if it doesn’t, and the published or copyright date in your internal documentation & your Works Cited if your source is from the Internet. One difference between them, never use the URL in the internal documentation, but always include the URL in the Works Cited – and you can use just the first part of the URL since the whole thing may be really long.

8. Speaking of that, what you have listed in your internal documentation should match the first thing you have written in each entry of your Works Cited. For example, the author, the name of the book, the Internet title, dictionary entry, etc. Never, never, never include JUST the URL for Internet sites in your Works Cited. You must include the other important information as well. Use the examples I gave you at the end of your project sheet if you have any questions. And don’t forget to reverse indent your Works Cited!

9. Make sure you write the internal documentation for your illustrations BOTH on your illustration and also in your paper. And don’t forget to include it in the Works Cited!

10. Your Works Cited entries should also be in the order that they occur in your paper.

11. Double check to make sure you don’t have anything in the internal documentation that isn’t in your Works Cited, and vice versa.

May God bless you as you work!! I love you and I’m praying for you!!!

Chemistry 4-19-17 Describing Chemical Reactions

CHEMISTRY: So tell me again – how do you know if a chemical reaction has occurred? Here’s the lecture on the evidences of a chemical change and the intro to balancing chemical equations. Great to be back to chemistry!
