1. Let’s see! In-class and Take-Home Working in a team using the PowerPoint file sent to you by Dr. Rodgers, build a scientific concept map. A concept map is a way of organizing and representing knowledge by connecting concepts, experiments, and other information together in logical ways. Hopefully, building this one will help you to achieve a better understanding of atomic orbitals.

2. Building a Concept Map for Atomic Orbitals Scientific Concept Map: a way of organizing and representing knowledge by connecting concepts, experiments, and other information Wave-particle Duality of Light Green ovals represent concepts Newton’s corpuscles Purple ovals represent historical concepts Electron gun Aimed at barrier Produces Interference pattern Yellow ovals represent experimental results Our goal is to put together a concept map leading to a better understanding of atomic orbitals Atomic Orbitals
