Learners study how images they see are transmitted to the brain.  In this sight lesson students complete several activities that have to do with visual pathways and field defects. 

Young scholars examine the eyeball and its parts.  In this sight lesson plan students divide into groups and complete a lab activity that includes creating a model.

Students investigate the Hubble telescope's role in astrophysics research. They complete a Webquest, watch a video, view Hubble photographs, play online games, answer discussion questions, and evaluate newspaper articles about optics.

In this color worksheet, young scholars answer questions involving the visible spectrum. These eleven short answer questions involve wavelength, lux, and the effects of color on mood.

Students explore the modern applications of robots and create one of the five parts of a robot that could solve a hypothetical public works problem. They study about the use of robots for laying fiber-optics cable in New Mexico by...

Pupils view six optical illusions and explain why the visual system might interpret them the way it does. They explore how illusions distort our sense of perspective, because they deceive us into seeing what we expect to see. Students...

Students use NASA satellite data of optical depth as a tool to determine volcanic activity on Reunion Island during 2000-2001. They access the data and utilize Excel to create a graph that has optical depth as a function of time for the...

Students conduct a brief astrophysics lab matching the EUVE spectra of various kinds of "mystery" stars with the spectra of known stars taken at Extreme Ultraviolet and optical wavelengths to determine their type.

Third graders study light and shadow, participate in mirror activities, and build a periscope.

Students use lecture and research to answer the question: Why is the sky blue? students research a variety of other sky phenomena, chart their observations and participate in experiments.

Students describe how the sun's rays produce colors. They describe how water causes the sun's rays of light to bend, producing a rainbow.
