Students will explore the refraction
property of light as they use diffraction gratings, the same tool inside
scientific spectroscopes, to view different light sources. Through
observation and experimentation students will discover that each element
produces a unique spectrum. They will develop an understanding of how
scientists use light waves to identify elements. |

Lesson Objectives
1)
Demonstrate an
understanding of the properties of light; particularly that white light
can be separated into a visible spectrum.
2)
Observe that different
colors of light have different wavelengths.
3)
Use spectroscopes to view
the unique spectrums of different elements. |
