Chemistry 1-31-17 Spectroscopy Lab

Posted on by

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 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 1-31-17 p-Block Elements

Posted on by

HON CHEMISTRY: Wow! There’s a ton of interesting and important stuff to know about the p block elements! Here’s the intro we did in class today.

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. Here are a few topics you might want to research a little deeper: the nitrogen cycle – why is grass greener after a lightening storm, arsenic poisoning – why it’s called inheritance powder, and the symptoms, and the details of the Marsh test.

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

Hon Chemistry 1-29-17 History of the Periodic Table & cLAB: Element Reverse Scavenger Hunt

Posted on by

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. We’ll continue with some of the rest of the Periodic Table tomorrow!

Chemistry 1-29-17 Wave Properties of Light

Posted on by

CHEMISTRY: So tell me again, if we’re supposed to be figuring out electrons, why are we studying waves? Here’s the lecture from Monday 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! Also lab – don’t forget your lab sheets and colored pencils. 🙂

Physics 1-29-17 Torque & Rotational Equilibrium

Posted on by

PHYSICS: Welcome to the first day of a brand new chapter in physics – one of the last we’ll do on mechanics!! No audio today, so here’s a past lecture on torque – a different kind of motion involved. So how’s the balance in your life right now?

Chemistry 1-25-17 Chapters 3A & 21 Test Overview

Posted on by

CHEMISTRY: Are you ready for the test tomorrow? Be careful and don’t take the test for granted! Also, make sure you got a copy of the Chapter 3A and the 21 Stuff to Know & Study Suggestions sheets on Edline.

Here is the test overview from today. Below that is the vodcast from the help session this morning.

Memorize everything and practice everything! And did I mention, PRACTICE!! God bless you! I’ll be praying!!

Physics 1-25-17 “Bombing Hitler’s Dams”

Posted on by

PHYSICS: A most awesome application of physics! Does it inspire you? I’m looking forward to seeing your first cars on Monday!

We’ll continue watching on tomorrow in class, but then you will finish it on your own. Click on the photo below to go to the PBS site to finish watching. Also, you may be able to find the movie on You Tube. Remember that you will turn in a total of ten applications of physics from the work described in the DVD – five them must be related to experiments that they did. Good stuff!!

Chemistry 1-24-17 Applications of Radioactivity, Pt. 2 and Fission & Fusion

Posted on by

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! Here’s a copy of the Chapter 21 Stuff to Know & Study Suggestions 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!

Chemistry 1-23-17 Applications of Radioactivity

Posted on by

CHEMISTRY: Radioactive isotopes all around! Did you ever dream there were so many applications of radioactivity? Thanks for the great job on adding to the lecture! This is a pic of a test used to check on blood flow through the heart during a stress test. Fun, huh!? Click on the link below the pic to learn more from Cedars-Sinai hospital.

Here’s the lecture from today – applications of radioactive isotopes. We’ll finish more applications and then fission and fusion tomorrow. Have you checked out the Chapter 21 Stuff to Know & Study Suggestions sheet on Edline? Help session will be Wednesday morning, 7:20ish A.M.

IMPORTANT: Don’t forget about the Half Life lab! Data is due when? Where? check the syllabus for info!
