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