WOW! It has been an incredibly awesome year for me, and I hope it has been for you too! God bless you as you are studying for your chemistry & honors chemistry exam! If you need a break, check out this awesome review of the elements: The Element Song or this New Periodic Table Song, but don’t get distracted by the challenge!!

Exam Help Session Wednesday morning, 7:20ish A.M. EXAM ROOM ASSIGNMENTS are listed below. IMPORTANT – Bring your textbook (and book fines) and your exam review packet to the chemistry room before you go to your exam room!

It is super, super important so study YOUR VERY BEST and remember to practice, practice, practice! This exam can make a HUGE difference in your average. FINISH STRONG, like you’ve been working all year!! Make flashcards out of the vocab, formulas, types of chemical reactions, etc. Practice writing chemical formulas, balancing equations, working the problems – try the practice tests on the online textbook or on sciencegeek.net, they’ll be really helpful. And get yourself plenty of snacks! :)

How’s the exam review coming? You know, I don’t just give you that thing for the extra credit. I give it to you because it will help you get organized and help you remember everything that’s going to be on the exam. As you answer each topic, keep studying it, if you’re having trouble!

EXAM ROOM ASSIGNMENTS are listed below. IMPORTANT – Bring your textbook (and book fines) and your exam review packet to the chemistry room before you go to your exam room. God bless you, I’m praying for you!!

CHEMISTRY: Great intro to the properties of acids and bases! Do you think you can apply them now?

Did your class get to the part about figuring out pH? If not, here is the lesson you need! 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: Up, up, and away!! Now just how many classes can you go flying hot air trash bags?

HON CHEMISTRY: Our first look at the gas laws: Boyle’s law, Charles Law, Gay-Lussac’s law . These guys did great work – and you’ve got to love their hair!!

Be sure you use Kelvin in the problems – not Celcius. And make double dog sure you use the formulas correctly! Rearrange that thing – no plug and play!!

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 and the beginning discussion of pressure.

HON CHEMISTRY: Good job with taking phase changes to the next level! Were you surprised at what happened when we added the salt to the ice water and boiling water? Don’t forget to bring an explanation on Tuesday.

Audio didn’t work on the recording today, so I’m posting the recording from last year. This isn’t the last lecture….but we’re getting close!!!

HON CHEMISTRY – Great work with pH! Good luck with the purple cabbage. I hope your family doesn’t run you out of the house!!

Also, good job on figuring out 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?

HON CHEMISTRY Great intro to the properties of acids and bases! Can you think you of ways to apply these concepts? Let’s talk more about pH tomorrow!

CHEMISTRY: Wow! We finished the chapter!! No you get to go and practice what you’ve learned – especially the activity series. Help session??

Practice, practice, practice! Don’t forget, you have to memorize the 17 types of chemical reactions and the activity series, but you also have to apply them! You need to know them so well, that it becomes second nature to you. I’ll be praying for you as you begin to study for the test!!:)

Homework update – Balancing Equations Worksheet 4 will be due on Friday.

PHYSICS: Today was the last of the applications of lenses. I love it when you get to see how physics crosses over into other disciplines of science – from physiology the other day with myopia and hyperopia and how lenses can help, to the applications today – how microscopes and telescopes work, and, ever important to know – why is sky blue!

Update on homework: the homework for thin lenses was incorrect. It should be: Pg. 508 – 512; 15 – 26 (Draw 24 – 26 to scale).

Speaking of lasts – LAST chapter test tomorrow!! What should you practice? Application of concepts, ray diagrams with mirrors and refraction through a transparent medium and lenses, and problems. Hey, here’s something to think about… can something really disappear into thin air? How??
