CHEMISTRY – Chocolate chip cookie dough model of the atom? Here’s the lecture from Tuesday on how scientists began to determine the structure of the atom and the existence of subatomic particles – well, the electron anyway. FYI – as we go on, 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!
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!
Change in plans! We’ll finish notes tomorrow and move the Model of the Atom activity to next Tuesday, the day after the test. Help session? What about Friday?

I liked the videos they were very interesting and it was cool seeing the actual scientist talk about their discoveries.
Thank you for giving us some time to work yesterday. I found it very helpful!
I wonder what made them so interested in these topics and how smart they really were.
The videos really helped me understand the experiments the scientists did.
I thought that the cathode ray tube experiment was cool when it emitted light.
Ms. Skinner! I just love learning about the history of the atom. It was so cool seeing John Dalton’s notes! 🙂
It’s amazing how they found all that out about the atom using only simple tools that they had.
Todays class was interesting hearing about atoms. I enjoyed our class today.
I enjoyed learning about how the atom was discovered.
