Activity: Augmented Reality and the Atomic Model
In this project, students will first work with a partner to select a common element from the periodic table to research. They will create a video using iPods to present their research and they will access the Aurasma app on iPods to upload their video. Students will create a trigger image using a picture of the element from the periodic table. Secondly, the students will use the Aurasma App to scan a different element’s trigger image and will use information from another group’s video to construct a model that replicates the atomic structure for the selected element.

Atoms, Model of the Atom, Atomic Theory, Emission Spectrum, Electromagnetic Spectrum, Subatomic Particles, Emission Spectrum, Electrons | High School
Lesson Plan: Modeling Energy in Chemistry: Energy and the Electron
This activity is designed for students to build a scientific argument about the relationship between energy and spectral lines by exploring how light interacts with atoms. In the process, students will examine proposed models of the hydrogen atom and use collected data to analyze the proposed models. They will then select one of the models and write a scientific argument to support their choice. Students will then review additional data to support and/or refute their selection. Based on their analysis, students will revise their selected model and construct a new argument to support their revisions.
