The main presentation is a PowerPoint with animated sequences showing the structure of the Rutherford-Bohr atomic model Support Material Readme (instructions for whole lesson) Learning Outcomes (PowerPoint) Starter Activity (PowerPoint and Worksheet) Main Activity (PowerPoint with worksheets and answer sheets) Lesson Notes (hand-out) Plenary Activity (PowerPoint and worksheet) It is intended for all science teachers but particularly those who are not physics specialists. It is, primarily, aimed at 14 to 16 year old pupils but can also be used at a higher level as a precursor to a more in-depth study of this topic. Normally, the activities would fill a 60 minute lesson but could be spread over two lessons if needs be. If you buy this resource, please print the Readme document as it contains the instructions and details of the files included. Learning Outcomes The learning outcomes are based on Bloom’s taxonomy of hierarchical classification: knowledge, comprehension, application, analysis, synthesis and evaluation. The lesson title and learning outcomes are: How Does Atomic Number Dictate Position In The Periodic Table? Learning Outcomes Knowledge to state the properties of sub-atomic particles to define atomic number and mass number Comprehension to state the difference between group number and period number Analysis to calculate the number of neutrons from the mass number and atomic number Differentiation The activities have varying degrees of differentiation; please refer to the Readme document.
