Original PromptDevelop a model to describe the scale and proportion of atoms and molecules.
This learning resource focuses on atomic structure and the relative scale of the universe. It starts with an overview of the subatomic particles: protons, neutrons, and electrons, including their charges and locations within an atom. Students are then challenged to use scientific notation to express sizes of various objects, from grains of sand to gold atoms. The material includes analysis questions to deepen understanding, such as explaining why atoms are mostly empty space and the importance of scientific notation. Additionally, it presents exercises to visualize molecular structures, identify bonding types, and correct common scientific misconceptions. Through these activities, students will hypothesize the effects of neutrons and protons on atomic identity and reflect on the limitations of 2D representations of 3D molecular structures.
