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 – they’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. πŸ™‚

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? πŸ™‚

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

Chemistry 1-8-18 Intro to Atomic Theory

CHEMISTRY: So how do you feel about being made from earth, air, water, and fire? Here’s the intro we did on how we ended up with the atomic theory. Had you ever heard of Lavosier, Proust, and Dalton?

Pretty impressive little theory that Dalton came up with, huh? Were you surprised as you made comparisons with the Modern Atomic Theory? Could you now take it a step further and show connections between the three laws we discussed today and Dalton’s atomic theory?

Speaking of impressive – a penny turning to gold – wow!! πŸ™‚

Physics 1-4-18 Impulse-Momentum Theorem

PHYSICS: Champions of the Marshmallow Blow Gun shoot off! I declare you co-champions! πŸ™‚

And wait – so that’s why you need good running shoes! Here’s our discussion from today on the intro to momentum and the impulse-momentum theorem. Did you understand the relationship between force and time? Let’s see if you can put it to practice tomorrow!

Have you looked at the syllabus? It may be really important – especially as pertains to future endeavors! πŸ˜‰
