Chemistry 4-6-21 Structure of the Atom

CHEMISTRY – Chocolate chip cookie dough model of the atom? That’s what Thompson thought the atom must look like! Here’s 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!

As we continue the explore the discovery of the structure of the atom, 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 4-6-21 Properties of Waves

PHYSICS: Here’s the vodcast on the properties of waves and the a link to the NASA video on wave motion for Tuesday. Do you remember anything from your earlier 8th grade physical science days? Problems are pretty simple for you, I think. Do you remember the main formula from chemistry? Speed = wavelength x frequency (c = λf).

Easy peasy – and don’t forget the applications!

Here’s the link to the NASA Launchpad video on wave motion – NASA Launchpad: Wave Motion. Since we’re not going to be able to play with slinkies today in person, this will be a good replacement!

Hon Chemistry 4-6-21 Blocks of the Periodic Table & Noble Gas Notation

HON CHEMISTRY: Here’s the lesson for Tuesday. Wow! You learned a lot today! Don’t we serve an awesome God?!? You probably knew the periodic table was really organized, but did you realize that it was THAT organized? Awesome!

Practice what you’ve learned!! You’ll get the hang of it and be as laid back as this “noble” fellow in no time! 😉
