Hon Chemistry 10-20-17 Chemical Formulas Review & Intro to Binary Molecular Formulas

Posted on by

HON CHEMISTRY: Okay, I’m not saying that learning to name and write chemical formulas is as bad as a jellyfish sting (you’ll get that in a minute!), but you do have to really, really pay attention to the details!! Here’s our review of the chemical formulas from last night’s homework AND an intro to writing formulas and names for binary molecular compounds.

Don’t freak out about binary molecular formulas! Part of it’s really similar to what you learned to do for ionic compounds, don’t you think? The other prefix part is totally different, though!

Make sure you keep everything straight. Find a way to organize all the information for yourself so you won’t get confused. Also, don’t forget the lists you have to memorize – chemical names for common substances, polyatomic ions, acids, and numerical prefixes. And practice, practice, practice!!!

And did I mention polyatomic ions? The quiz on them has been moved to THIS COMING Tuesday! Are you getting ready??

Hon Chemistry 10-19-17 Chemical Names & Formulas

Posted on by

HON CHEMISTRY: Great start on writing and naming chemical formulas! What did you think? Do-able? Absolutely! Make sure to take time to practice, practice, practice, and learn it step by step. You’ll be as lost as ball in high weeds if you let yourself get behind!

Tons of memorization for this chapter – monatomic ions, polyatomic ions, and this is just the beginning! Start now!!

Chemistry 10-18-17 Conservation of Energy

Posted on by

CHEMISTRY – Happy Day!! We finished the chapter! Now it’s time to go apply what you’ve learned. Have you begun to think about ways you could separate that mixture? And what about a Plan B? 😉

So can energy be destroyed? Good job on tracing the energy transformations from one form to another. Applications, applications! Make sure you can apply what you learned today – on the test (and in life!). Did I mention that already?

Hey, have you had a chance to check out the chapter 1 study suggestion sheet? Let me know if there is anything you need help with before the test! (And you’re still learning the symbols of the elements, right?!?) 🙂

Physics 10-18-17 Newton’s Law of Inertia

Posted on by

PHYSICS: Remind me again why didn’t that pen go flying across the room instead of dropping into the bottle? Hmmm…..

So what do you reckon is the inertia of this car? Great start today relating mass to inertia! Now go forth and apply what you know to find the mass of that spool of copper wire! Wait, did a say copper wire, I meant the mass of that unknown substance!

Chemistry 10-17-17 Elements & Intro to the Periodic Table

Posted on by

CHEMISTRY – Happy Tuesday! Here’s our overview of the elements and intro to the periodic table. Did you feel like it was mostly review?

How is the element handbook search going? You will be responsible for the information from Handbook Search 1 on the test. Tell enough to show what distinguishes that element as the type that it is – physical and chemical properties, where it can be found, what it’s used for, anything particularly unusual about the element, but don’t go into minute detail – just the main facts. You for sure don’t have to copy information from all the tables in the book.

Here is the link for the video clips on copper, phosphorus, and silicon that you will need to watch for the Element Handbook Search and for the TEST!! www.periodicvideos.com. The information on these video clips will be on the test.

Speaking of the test, have you had a chance to check out the Chapter 1 Stuff to Know sheet? Let me know if there is anything you need help with before the test! (And you’re still learning the symbols of the elements, right?!?)

Chemistry 10-16-17 Classification of Matter

CHEMISTRY: Here’s a mixture that looks like it might be worth investigating – bacon caramel popcorn! I mean, I like bacon and I like caramel popcorn, but bacon caramel popcorn? Hmmmm….

So now that you know about mixtures, could you figure out how to separate one? Keep these notes handy!

Hon Chemistry 10-13-17 Elements & Intro to the Periodic Table

Posted on by

HON CHEMISTRY – Wow! Do you realize what we just did?!? We finished the chapter!!! Here’s the last lecture from chapter 1 – an overview of the elements and intro to the periodic table. Did you feel like it was mostly review?

Now for the element handbook search! You will be responsible for that information – both search 1 & 2, on the test. On the first part, tell enough to show what distinguishes that element as the type that it is, and also anything particularly unusual about the element, but don’t go into minute detail – just the main facts.

Another great resource for the Element Handbook Search (and for the TEST!!) are these video clips on copper, phosphorus, and silicon that a group of chemistry researchers have put together at www.periodicvideos.com. Watch these as you do the element handbook search. The information on these video clips will be on the test.

Hey, have you had a chance to check out the chapter 1 study suggestion sheet? Let me know if there is anything you need help with before the test! (And you’re still learning the symbols of the elements, right?!?)

Physics 10-4-17 Motion Down a River and Kid on a Slide with a Water Gun – Relative Motion Revisited

Posted on by

PHYSICS – Wow, we finally made it to the official end of chapter 3! Do you realize how much you’ve accomplished? Awesome!

How’d you do with relative motion “revisited”? You know, you’ve done this already. The only new part is the motion of objects in the same direction and opposite directions, relative to each other. Don’t forget, you’ll use what you learned about vector addition to work those “boat goes across a river” and “plane experiences a head wind” types of problems.

Need extra help? Help session tomorrow morning, Thursday, 7:20ish.

Chemistry 10-4-17 Properties & Changes

Posted on by

CHEMISTRY: So how do you know if something is a physical or a chemical change? Applications, applications! Make sure you can apply what you learned today. Ditto on the law of conservation of mass.

Don’t forget that we will do the thLab: Candle Observation in class tomorrow!
