Students struggle with the development of the atomic theory and all the dates and people and specifics.
Use this worksheet to help your students through an excellent 11 minute TED video on atomic theory. Students learn about the development of the Plum Pudding Model, Bohr Shell and Quantum models with excellent and clear descriptions.
Use this when you have a sub (it will take 20 minutes if they start and stop the video) or a homework assignment or simply show it in class.
