Happy Snow Day!!

Hallelujah! God is good! I hope you’ve enjoyed your snow day!!

Here’s the revised scheduled for all classes – pretty much we’ll just take up on the syllabus where we left off:

HON CHEMISTRY: Bring your Spectroscopy lab – we’ll finish it in class on Tuesday. Also bring your colored pencils! We’ll begin Friday’s lesson next Wednesday.

CHEMISTRY: We’ll just take up on the syllabus where we left off. No new homework, we’ll just pretend that this coming Tuesday is last Thursday! ๐Ÿ˜‰

HON PHYSICS: Conservation of Momentum lab moved to Tuesday!

Enjoy your day off!!

Hon Chemistry 1-11-18 Spectroscopy Lab, Part 2

HON CHEMISTRY: How’d you like playing with light?!? Here’s the intro to Part 2 of the lab.

Are you clear on how to turn in the lab report? Observations from Part 1 and the diffraction grating 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 card stock or heavy white paper, and then both drawings mounted together on one sheet of construction paper. Be sure to label everything.

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. We’ll finish the last part of the procedure the next time we have sun. Check the syllabus for the due date!

Chemistry 1-11-18 Structure of the Atom, Pt. 2

CHEMISTRY: I love our chapels this week and hearing from God’s Word – but it does make for short classes! Here’s the last of our discussion on how scientists discovered protons and neutrons. You know, in class yesterday and today I just gave you mostly one name to go with each, but don’t forget they work with other scientists to get the job done!!

Make sure you know the name of the scientists, the name of their experiments, be able to draw a diagram of their experiment, and describe how they interpreted the experimental results that led to their discoveries.

Don’t forget about these video clips we watched in class, they’ll help you review the different experiment that the guys like Thompson and Rutherford did. Here’s another one on The Discovery of the Nucleus. And again – do you think there could be anything smaller than protons, neutrons, and electrons? Hmmmmm……

Physics 1-11-18 Collisions Problems with Energy & More!

PHYSICS: Great job on the problems so far!! Here’s the preview from today – dart in the block of wood, bird on the swing, car crash, and a start on the billiard balls. This cute little bird isn’t on a swing, but he is one I came beak to nose with on a mission trip to Costa Rica!

On to a more practical application tomorrow. Speaking of which, any questions? Light bulb? Questions??

Chemistry 1-10-18 Structure of the Atom

CHEMISTRY – Chocolate chip cookie dough model of the atom? Here’s the beginning of our discussion of how scientists began to determine the structure of the atom and the existence of subatomic particles. For each, make sure you know the name of the scientists, the name of their experiments, be able to draw a diagram of their experiment, and describe how they interpreted the experimental results that led to their discoveries. Wow, that’s a mouthful!

Also, here are some video clips that I want everyone to watch that will help make things a bit clearer. Click here for the video on the Cathode Ray Tube Experiment that Thompson did, and also for the video clips that I want you to watch on The Discovery of the Electron and The Discovery of the Nucleus. All of these will be great tools in studying for the test!

Physics 1-10-18 Collision Problems & Bouncing

PHYSICS: Here’s a new way to study collisions! Somebody’s having way too much fun with veggies!

How are you doing with the problems? Since we didn’t really work any in class today, I’ve found an old vodcast that I’ve posted below that also has some of last night’s kinetic energy problems as well as the lesson on bouncing, etc.

Are you ready to crank it up a bit? Here’s a hint – check for connections between the conservation of momentum and the conservation of energy. Also, that old vodcast below might have some hints for you! You can do it!

Hon Chemistry 1-10-18 Photoelectric Effect

HON CHEMISTRY: Wow check out this awesome example of the photoelectric effect – a giant solar flower in Buenos Aires, Argentina! It moves as it follows the sun. Click on the link to learn more. There’s also a link below the vodcast. Giant Solar Flower

Awesome field trip today! Hey what about other applications of the photoelectric effect? Are there tiny people living in boxes above the doors at Wal-mart and Target? What about solar calculators? And hey – what about those automatic flush toilets?!

Physics 1-9-18 Collisions, Pt. 2 & Bouncing

PHYSICS: Collisions โ€“ theyโ€™re all around us and they all obey the law of conservation of momentum. Great job on setting up the problems in class today – now on to working them tonight! Check for connections between the conservation of momentum and the conservation of energy. ๐Ÿ™‚

Oh – and watch out for flying ping pong balls!!

Hon Chemistry 1-9-18 Wave Properties of Light

HON CHEMISTRY: Isn’t this a super cool picture of light? So tell me again, if we’re supposed to be figuring out electrons, why are we studying waves?

How’d you like the light problems so far? I forgot to hit “resume recording” after I paused, I’m posting a lecture from last year. We’ll resume with the photoelectric effect tomorrow!

Hon Chemistry 1-8-18 The Electromagnetic Spectrum & Intro to Spectroscopy

HON CHEMISTRY: Light can do some pretty crazy things, huh? Great start to our study of light! And why are we studying light? ๐Ÿ™‚

I’m thinking you’ve probably memorized the electromagnetic spectrum after that inspirational song; however, also sure you also know the uses of the different types (all except for long waves). Just in case you’d like to hear it again: Electromagnetic Spectrum Song
