This is a lesson about using light to identify the composition of an object. Learners will use a spectrograph to gather data about light sources. Using the data they’ve collected, students are able to make comparisons between different light... (View More) sources and make conjectures about the composition of a mystery light source. The activity is part of Project Spectra, a science and engineering program for middle-high school students, focusing on how light is used to explore the Solar System. (View Less)

This is a lesson about emission spectra. Learners will look at various light sources (including glow sticks and christmas lights) and make conjectures about their composition. The activity is part of Project Spectra, a science and engineering... (View More) program for middle-high school students, focusing on how light is used to explore the Solar System. (View Less)

Learners will explore the conditions required for water to be in a liquid state. They discover that temperature is the essential variable. They then explore how temperature is not a measure of heat but of the average motion of molecules of a... (View More) substance. In addition, they will identify the properties of solids, liquids and gasses and will cite similarities and differences in those properties. The lesson models scientific inquiry using the 5E instructional model and includes teacher notes, prerequisite concepts, common misconceptions, student journal and reading. This is lesson 3 in the Astro-Venture Astronomy Unit. The lessons are designed for educators to use in conjunction with the Astro-Venture multimedia modules. (View Less)
