Ultraviolet light Lesson Plans

Students explore the effects of ultraviolet light on Lumbriculus. They expose ultraviolet light to Lumbriculus (worm) and determine the lethal exposure time. They examine the worm and record their observations.

Students investigate the effects of UV light and ozone on plant and bacteria growth. In this ultraviolet light and ozone lesson plan, students grow bean and mustard greens to study the effects of UV light and ozone on the plant growth. They also grow E. Coli cells and expose them to the UV light as well.

Students realize the importance of organisms as standards of measurement and experimentation.The first lab is a simple survival curve that demonstrates the effects of UV light on cells. The second lab looks at repair mechanisms of the DNA molecule from visible light. The third lab uses yeast as a measurement tool to test the effectiveness of sunscreens.

Students investigate materials that emit light. In this deep ocean instructional activity, students compare and contrast materials that emit light under certain conditions and infer the light-producing process. They explain three ways this evidence is used to study deep-sea organisms.

Students investigate color, light and excited electrons. In this light and the electromagnetic spectrum lesson plan, students produce waves using slinkys, they observe a continuous spectrum with a prism and an overhead projector, they observe flame tests to identify elements and they observe luminescence. Students complete the lesson by drawing diagrams of waves, drawing the electromagnetic spectrum and identifying unknown elements.

Students explore the concept that not all light is visible to the human eye. Although UV light is not visible, it can still be harmful, causing sunburns or skin cancer. They use special beads to detect UV light around the school. Students then conduct an experiment to determine what types of materials are best for blocking UV light on Earth, as well as in space.

Students explore the properties of light. For this light lesson, students investigate visible light by viewing a website, examining an electromagnetic spectrum chart, and observing light demonstrations. Students write about their observations in a science journal.

Young scholars examine the function of the passport system of their country. Then they make simple accordion-fold books. Students also design and fabricate stamps with which to record information in their books. Finally, they identify and interpret recent technological devices used to cut down on passport crime, such as embedded photographs seen only with ultraviolet light and holographic messages.

Students examine bioluminescence and camouflage of deep sea creatures. In this deep sea creatures lesson, students investigate the visible and near-visible light spectrum. They work in small groups to complete a light, color, and camouflage activity using the given worksheet.

Students analyze infrared imaging by looking at an image of a familiar geothermal feature, Old Faithful. They recognize the visible light image of the famous geyser, and figure out what the infrared image is showing them.
