Chemistry 2-8-18 Photoelectric Effect & Wave Problems

CHEMISTRY: Fun field trip today!! Good job coming up with examples of the photoelectric effect. What? There really aren’t tiny people living in boxes above the doors at Wal-mart? And I just thought of another one, what about those automatic flush toilets!

What did you think about the energy problems? Again, make sure you not only memorize formulas, but also be careful to learn the symbols and units for each of the quantities you’re going to use, it’s easy to get them confused!

Need practice? What about a help session?

Hon Chemistry 2-8-17 Electron Affinity, Ionic Radii & Electronegativity

HON CHEMISTRY: Here’s the last of the trends – not car trends, periodic trends! For now, it’s an lesson from last year, so fast forward past the syllabus part! 😉

Have you begun by watching the videos on the Periodic Table of Videos site? Great place to gather information for the cLAB!

The videos that you must watch from the s-block are potassium, magnesium, and calcium.

The videos you need to watch for the p-Block are carbon, nitrogen, oxygen, fluorine, and chlorine. http://periodicvideos.com/

The elements from the d block that I especially want you to watch are copper and mercury. And there are other interesting ones you might like to watch just for fun!

The videos on from the f-Block that you need to watch are: neodymium, thorium, and

Hon Chemistry 2-7-18 Atomic Radii & Ionization Energy

HON CHEMISTRY: Hey guys, here’s the first lecture on periodic trends – atomic radii and ionization energy. You made some great connections today!

If you’d like to get a head start on the element videos that I talked about in class today, they are at periodicvideos.com. Very interesting(!), with tons of useful information!

The videos that you must watch from the s-block for the test are potassium, magnesium, and calcium.

The videos you need to watch for the p-Block are carbon, nitrogen, oxygen, fluorine, and chlorine. http://periodicvideos.com/

The elements from the d block that I especially want you to watch are copper and mercury. And there are other interesting ones you might like to watch just for fun!

The videos on from the f-Block that you need to watch are: neodymium, thorium, and uranium. Go pop some popcorn and have some movie time!

King of the Hill Competition 2018

PHYSICS: Terrific job on the King of the Hill competition!!! I’m really proud of the work that all of you did on your cars.

It was a fierce, head to head battle with cars flying all over the track, but at last the strongest car emerged victorious! Congratulations, Brendan, on being King of the Hill! Also, congrats to Milie and Ethan for winning the speed and distance races!

Chemistry 2-6-18 Wave Properties of Light

CHEMISTRY: So tell me again, if we’re supposed to be figuring out electrons, why are we studying waves? Here’s the lecture from Tuesday on that very thing!

Make sure you know the types of electromagnetic radiation and the uses of most of them (all except for long waves). And just in case you really need to sing that song again, here’s The Electromagnetic Spectrum Song

How did you like the light problem formulas – so far? We’ll explore wave problems further tomorrow – be sure to bring a calculator to class!

Physics 2-5-18 Circular Motion

PHYSICS: So is being unbalanced a bad thing? Here’s the lecture from Monday on unbalanced torques! Well, on circular motion. Lab on centripetal force and acceleration Wednesday. Prepare to duck!

But first – King of the Hill Competition tomorrow!!

Chemistry 2-5-18 Spectroscopy Lab

CHEMISTRY: How’d you like playing with light? Kind of pretty, huh?

Are you clear on how to turn in the lab report? Observations from the diffraction grating today will be in two parts: 1) the written observation – answers to those four questions for BOTH types of light on notebook paper, and 2) your drawings of both kinds of light on different half sheets of card stock or heavy white paper, and then both drawings mounted together on one side of a single sheet of construction paper. Be sure to label with the type of light!

Observations from Part 2 with the spectroscope will be answered on the actual lab sheets/packet. Be sure and read ahead so that you can double check to make sure you answered every single observation and question. The entire packet will be due on Monday!!

Hon Chemistry 2-5-18 History of the Periodic Table & cLAB: Element Reverse Scavenger Hunt

HON CHEMISTRY: Great start to a new chapter! I love that you are going to be learning to research some really cool stuff about the elements on the Periodic Table.

Here is the intro the the history of the periodic table and and your short intro to the cLAB: Element Reverse Scavenger Hunt. This doesn’t exactly match what we did in class, but it’s a good start. Begin the vodcast at 4 minutes or so. We’ll continue with some of the rest of the Periodic Table tomorrow!

Chemistry 1-30-18 Applications of Radioactivity, Pt. 2 and Fission & Fusion

CHEMISTRY: Hey guys! Here’s the laaaaast part of the charter – fission and fusion. Have you started studying? Be careful and don’t take the test for granted! And don’t forget to check out the the Chapter 21 Stuff to Know & sheet.

Make sure you keep practicing half-life problems and nuclear equations. Also, make sure you’ve memorize the nuclear symbols for alpha particles, beta particles, positrons, neutrons, and protons. And then there are tons of notes on the conceptual stuff. Properties of radioactivity, people, types of radioactive decay, applications of radioactivity, definitions, definitions, and definitions!

Help session Thursday morning, 7:20ish A.M.
