Are You Ready for the Exam?!?

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!!

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, they’ll be really helpful. And get yourself plenty of snacks! πŸ™‚

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! You don’t do the last few items that we didn’t go over in class. Check under the worksheet tab if you need another copy. God bless you, I’m praying for you!!

Hon Chemistry 5-16-13 Intro to Colligative Properties

HON CHEMISTRY: Oh no, we didn’t – did we? The last lecture of the year? No way!!!!

It’s been an awesome year, and I’m blessed to have had you guys in honors chemistry. Now go forth and conquer the exam!!

Acids, Bases, & Intro to pH, 5-14-13

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

You did a great 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 5-13-13 Intro to Ideal Gas Law

HON CHEMISTRY: How much fun can you have with a Sprite can? Wow! Did you have a heart attack? More importantly can you tell me why it did what it did? Think about words like steam, condensation, atmospheric pressure.

How’d you like putting the gas laws together in the ideal gas law? Pretty cool, huh?!? Don’t forget to memorize R. We’ll get to the water boiling in the syringe tomorrow!

Hon Chemistry 5-10-13 Gas Laws, Pt. 2

HON CHEMISTRY: Okay, for the record, water balloons do not obey Avogadro’s Law, but gas balloons do! Equal volume balloons contain the same number of molecules. Yay, another great conversion factor!!

How’d you like playing around with the gas laws? Super cool the way you maneuvered it around like that to use something like density!

Sooooo… no test Monday! Check for the update on the syllabus. Have a great weekend!!

Chemistry 5-10-13 Stoichiometry

HON CHEMISTRY: Wow! Great job today – and I wasn’t even there 1st and 2nd period! Thanks for letting me go to kindergarten graduation!

Here’s your first lecture on reaction stoichiometry. You’re doing a great job applying what you remember about moles from earlier this year! Dont’ forget the keys! Now all you need is some practice and you’ll have it down pat. πŸ™‚

BTW – here’s the vodcast I showed 1st and 2nd periods. You won’t be doing the thLAB on making cookies. Instead, this weekend you will be doing the thLAB: pH Paper. Won’t smell as good.

Hon Chemistry 5-8-13 Gas Laws – Part 1

HON CHEMISTRY: Wow, does it feel like we’re moving 100 miles per hour? We’re really not, it just sounds new and fast! Here’s the lecture on the first two gas laws – Boyle’s law and Charles law.

I was excited to hear about your results with thLAB on Boyle’s law! Let’s play with hot air “balloons” tomorrow! πŸ™‚
