HON CHEMISTRY: Here’s the lecture from Wednesday 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 a little history on The Discovery of the Electron. Do you think there could be anything smaller? Than an electron, I mean??
By the way – how do you feel about playing scientist tomorrow? How is what you’re going to do similar to the work of early scientists in discovering the structure of the atom? Don’t forget to bring your sock/can atoms with the surprise items inside! Don’t forget that you DO NOT have to cut your sock. Just get a sock that’s really long, and stick a clean, empty can inside it. Well, make sure you put your mystery items (three or more) inside the can first!
