Computer simulations for minds-on learning with ``Project Spectra!''

How do we gain information about the Sun? How do we know Mars has CO2 or that Titan has a nitrogen-rich atmosphere? How do we use light in astronomy? These concepts are something education professionals generally struggle with because they are abstract. Making use of visualizations and presenting material so it can be manipulated is the easiest way to conquer abstractions to bring them home to students. Using simulations and computer interactives (games) where students experience and manipulate the information makes concepts accessible. “Project Spectra!” is a science and engineering program that uses computer-based Flash interactives to expose students to astronomical spectroscopy and actual data in a way that is not possible with traditional in-class activities. Visualizing lessons with multi-media is a way to solidify understanding and retention of knowledge and is completely unlike its paper-and-pencil counterpart. To engage students in “Project Spectra!”, students are given a mission, which connects them with the research at hand. Missions range from exploring remote planetary atmospheres and surfaces, experimenting with the Sun using different filters, and comparing spectroscopic atmospheric features between different bodies. Additionally, students have an opportunity to learn about NASA missions, view movies, and see images connected with their mission. In the end, students are asked critical thinking questions and conduct web-based research. These interactives complement the in-class activities where students engineer spectrographs and explore the electromagnetic spectrum.
