Lab: Emissions of Light
In this lab, students will examine three different ways to excite electrons to produce visible light found in the electromagnetic spectrum. The students will then see that this visible light has a specific color, wavelength, and frequency. They will use their knowledge of the speed of light and plank's equation to examine the energy involved in the emission of light. Finally, the students will then apply their knowledge of the emission spectrum to how the composition of stars is determined.

Lesson Plan: Chemical Analysis of Martian Rocks
In this lesson, students are challenged to analyze the spectral graphs obtained by the Curiosity Mars Rover. Based on their examination students will determine the component elements of each sample, as well as the relative abundance of each element. With this information the student will complete calculations to find the empirical formula and identify the composition of the unknown rock. Finally students will complete research to see if these rocks are actually like those on Earth.

Lesson Plan: Elements Are Out of This World
In this lesson, students will learn about the elements that make up Earth’s atmosphere and lithosphere and then compare and contrast the information with the elements that compose various other astronomical objects.

Lesson Plan: Let it Glow
In this lesson students will investigate the fluorescence of a variety of everyday items as well as prepared samples under a black light. Students will examine the concepts of absorption and subsequent emission of photons, as well as wavelength, frequency, and energy of electromagnetic radiation. As extension activities, students will learn about phosphorescence and research real-life applications of photoluminescence.

Lab: Build a Spectroscope
In this lab, the students will make and use a spectroscope to identify the spectra within various types of light bulbs. The students will then develop an improved design for the spectroscope.

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.
