ACT Science Reasoning Hints, 5-18-12, Day 2 ….. the rest, for now

Are you ready to start making your own luck? Good luck as you begin practicing for the ACT this summer. Here’s the second part of the hints for taking the ACT that we did on Thursday. Practice, practice, practice!!!

And if you are interested in a summer ACT Science Reasoning prep session, check out the form below.

One Last Help Session & Good Luck Studying for Exams!!

studying

Good luck studying for your chemistry & honors chemistry exam! 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 sciencegeek.net, they’ll be really helpful. And get yourself plenty of snacks! 🙂

Do you need one last help session? I’ll be at school Tuesday morning at 7:15ish if you’d like to practice or if you need some help with something!

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. I’ve linked a copy of the exam review below, if you need it. Good luck, I’ll be praying for you!!

ACT Science Reasoning Test Prep, Part 1, for now… 5-16-12

Wow! Did you realize there was that much involved in getting ready for one test? The ACT is so very do-able! All the answers are there, you just have to use what you know how to do to find them, and that takes practice, practice, practice.

Do you have a better grasp of the skills that you’ll need and techniques you can use to be successful? Save this vodcast for later, and be sure to watch in several weeks before your next ACT. What an ACT prep day this summer before the June ACT – maybe Monday, Jun 4, or Thursday, June ? Let me know what you think. Fun times!!! 🙂

Chemistry 5-15-12 Intro to pH

CHEMISTRY: Wow! Can you believe it? The laaaaaaaaaaaassst official chemical lesson of the year! Nope, I can’t believe it!

Great intro to the properties of acids and bases. 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? Speaking of hydrangeas, here’s one from my back yard. Kind of out of focus, but can you spot the “visitor” in the right corner?

Hon Chemistry 5-15-12 Change in State

HON CHEMISTRY: So that’s why even in July you are so cold when you get out of the pool! So today was the laaaaaaasssst lecture of the year – an overview of the implications of change in state. So again, which is worse, a boiling water burn or a steam burn? And now do you understand why we are made out of so much water? Isn’t God great! In every thing and in every way He made us is for a purpose!!

Caution – You know I told you I forgot to turn on the mic – well here is a vodcast from a few year ago, and the video is two-toned. Yep, that’s what I said, two toned. But it still has good info, so I think you can live with it. 🙂

Hon Chemistry 5-14-12 Intro to pH

HON CHEMISTRY: Great job with pH today. What did you think about the indicators? Can you think of anything that changes color in the presence of an acid or base? What about tea? Have you noticed how it changes to a lighter shade when you add lemon?

Acids mean H30+ ions and pH, bases mean OH- ions 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? By the way, don’t forget to go back and make sure you are clear on the properties of acids and bases and some of the uses of them.

Chemistry 5-9-12 Chapter 8 Test Review

CHEMISTRY: Good luck tomorrow! Here’s the vodcast from today on our short test review. Poor Daphne and gummy bear!

Practice tonight, and make sure you have everything memorized. You can get help in memorizing the 17 types of chemical reactions on quizlet.com (and also on the polyatomic ions from last semester). Here’s a link to the 17 types of reactions on quizlet – http://quizlet.com/11793692/chemistry-chemical-reactions-flash-cards/. Thanks, Nicholas!!

Make sure you are also practice balancing equations. You can go to sciencegeek.net and find lots of interactive practice on balancing equations in the Chemistry Review Activities under Unit 3 and maybe some others. Also, the vodcast from today has the answers to the back page of Worksheet 4. Practice doing those, that will help a lot!

Another source of help is your online textbook at my.hrw.com. Click on the “Visual Concepts” or “Review Activities” tabs at the top of the chapter page for the extra tutorials and quizes. I love you and I’ll be praying for you!!

Hon Chemistry 5-9-12 Chapters 10a & 11 Test Review

HON CHEMISTRY: Good luck studying for the test on chapter 11! Here are both the help session from this morning and the test review from today’s class. The first one is the help session. I think.

Have you made your “stuff to know, stuff to know how to apply, and stuff to know how to do” list? Here are the laws and people I can think of, can you think of any more? Boyle’s law, Charles law, Gay-Lussac’s law, combined gas law, Dalton’s law of partial pressure, Avogadro’s Law, Gay-Lussac’s law of combining volumes, and Graham’s law of effusion. And don’t forget pressure. Whew!

And don’t forget, working problems is great, but make sure you can apply the concepts! Good luck, I’ll be praying for you, you can do it!!

Hon Chemistry 5-8-12 Ideal Gas Law & Gas Stoichiometry

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 ideal gas law? Super cool the way you maneuvered it around like that to use something like density!

Also – at the very end, after you left, I added a bit more about Graham’s law of effusion. I think you’ll find it a fairly easy formula to use. Don’t get stuck if it doesn’t give you specific masses or volumes. Remember what we did about that before.

Need some extra practice? Help session Wednesday morning at 7:15ish A.M. Now, go play with Henry’s Law! 🙂

Hon Chemistry 5-7-12 Gas Laws – Part 2

HON CHEMISTRY: Wow, it’s been forever since I’ve had a chance to post – but I think I’m just about caught up on everything we’ve done so far with gases. Here’s the lecture on the rest of the gas laws – Charles law, Gay-Lussac’s law, and the combined gas law. I’ve had to pull one from the past, so let me know if it doesn’t work.

Any questions about the Boyle’s law lab? Let’s talk about gas stoichiometry tomorrow! 🙂
