PHYSICS: You are going to be amazed at the effect of change in surface area on the velocity of water, and especially the pressure of water, flowing through a tube! Thaaaaat explains how a calm ride on a lazy river can turn crazy in just a few seconds!
The first vodcast below has the lesson for Friday – Bernoulli Part 1. (Static at the beginning, but it clears up at about 3 minutes.) In it we mainly concentrate on quantitative applications of Bernoulli’s Principle and a few practical applications. Here’s Julius Sumner Miller Bernoulli video on YouTube if you missed him in class!
The second vodcast below is a peek into the Bernoulli problems – Bernoulli Part 2. My best hint – Remember the concepts behind the formulas you want to use!!
CHEMISTRY: Wow! Did you every dream there was that much interesting and important stuff to know about the s, p, d, and f block elements?! Here’s the final day – we ran through all the slides, clarified some information and filled in gaps you might have had.
As you are studying, make sure you go back and practice figuring out the period, block, group, and type of element from the electron configuration. And don’t forget the topics I asked you to research for yourself that you will find on the Chapter 5 Stuff to Know Sheet on Edline!!
To make your research even more interesting(!), there are some really interesting videos with tons of useful information at this site: http://periodicvideos.com/
Some great videos to watch for the p-Block are carbon, nitrogen, oxygen, fluorine, and chlorine. http://periodicvideos.com/
HON CHEMISTRY: Molten iron, wow! Here’s the lecture for Friday on the rest of the notes on ionic vs. covalent bonding, followed by metallic bonding.
Aren’t you glad there are no structures to draw for metallic bonds?! Make sure you can use the electron sea model to explain the properties of metals.
Aren’t you glad there are no structures to draw for metallic bonds?! Make sure you can use the electron sea model to explain the properties of metals. Also be able to compare and contrast all three types of bonds.
Have you made your own Chapter 6 “Stuff to Know Sheet”? Great way to get organized as you get ready for this test on Tuesday!!
Happy Snow Day! Yay, you get to do chemistry and physics in your pajamas today!! Sipping a cup of coffee or hot chocolate, watching a chemistry or physics lesson online – it doesn’t get much better than that!!
You must watch lessons for any day you were not in class – the vodcasts are listed by date in the posts below this one. For regular chemistry and physics, that means the vodcasts for Wednesday & Thursday. For honors chemistry, it’s just the lesson for Thursday. Interact with the vodcast! Take notes, make a list of any questions you have, and then do the homework.
PHYSICS: Did you realize that fluids could produce that much force? Make’s you wonder at the awesome way God designed those beautiful under water sea creatures to withstand so much pressure, doesn’t it? This little creature is a lionfish from the waters of Lembeh, Indonesia.
Oh, and here’s the lecture on Pascal’s law and hydraulics and the like.
HON CHEMISTRY: Hey guys, here’s the lecture for Thursday on ionic bonding. If you are not in class for whatever reason – the play, basketball, SNOW!!!, you are required to watch this vodcast. Homework for Thursday night is due Friday – or the next day we are in class.
Keep in mind that when you write ionic bonding, you’re not trying to arrange a single structure like you do with Lewis structures. Instead, you’re writing an equation that shows electrons being lost by one atom and gained by another atom. And make sure you put the dots in the right order!
Also important, pay close attention to the comparisons of ionic and covalent bonds – and WHY! And whatever you do, stay away from bubble baths if you have mortal enemies!
CHEMISTRY: Here’s the lesson for Thursday and the last of the periodic trends – not car trends, periodic trends! Now on to some serious preparations for the test!!
Remember, you are required to watch this vodcast. The homework from Thursday will be due Friday – or the next day we are in class.
Don’t forget the Chapter 5 Stuff to Know sheet on Edline. It will be a great reinforcement as you begin to study and complete your notes on the properties and uses of the elements!!! It will be a great review as you are preparing for the test!!!
PHYSICS: So when you were floating in the pool this summer, did you enjoy your fellowship with buoyant forces? Here’s the lecture for Wednesday – Archimedes’ Principle. Great topic for investigation!
CHEMISTRY: Hey guys, here’s the first lecture on periodic trends – atomic radii, ionization energy, and electron affinity. It’s a great opportunity to make connections and discover why elements behave the way they do!
Remember, you are required to watch this vodcast. The homework from Wednesday will be due Thursday – or the next day we are in class. The vodcast from Thursday’s lesson is in the next post.
Don’t forget the Chapter 5 Stuff to Know sheet on Edline. It will be a great reinforcement as you begin to study and complete your notes on the properties and uses of the elements!!! And you might just learn something along the way! It will be a great review as you start to prepare for the test. Wait – did I say test?!?
HON CHEMISTRY: Who knew we’d be doing geometry in chemistry?!? You did a great job today! Lewis structures, multiple bonds, resonance, and now polyatomic ions and molecular geometry – wow, that’s a lot you’ve conquered in the last few days!
Molecular geometry is super easy. Make sure you know how to draw Lewis structures, then determine the type of ABE structure and you’ve got it. Easy-peazy!
Here’s some good advice – don’t take shortcuts. Learn the proper steps on the easier molecules, and you’ll be able to do the hard ones. And if it’s still all Greek to you, don’t worry! Keep practicing and you’ll get it, I promise!! Don’t forget to count electrons and don’t forget CONS!
