Wavelength Lesson Plans

Students investigate the wavelength of light using diffraction grating. In this wavelength of light lesson plan, students use a diffraction grating to determine the wavelength of yellow light and check their results with the accepted value. They determine the measurement in nanometers and calculate the percent error between the actual and experimental values.

Students use an on line website to simulate the effects of light intensity and wavelength on photosynthesis. In this photosynthesis lesson plan, students determine how wavelength of light and intensity of light affect the rate at which photosynthesis takes place. Students monitor the amount of ATP produced and create two graphs using the link, Create a Graph or a spreadsheet. They write their conclusion about the effects of these two variables.

Students create a paper model that demonstrates wave interference for 3 wavelength from 2 sources. In this light and wave instructional activity, students use a real spectrometer and observe and measure the wavelength of spectral lines. Students then, draw a diagram of a spectroscope to explain its parts and their features.

Students investigate electromagnetic energy and the electromagnetic spectrum. In this light energy lesson, students observe 7 items represented in the electromagnetic spectrum and make a poster of all the things the items have in common. Students observe a box of water and they create waves in the water to observe the relationship between energy and wavelength. They observe a light shining on a prism and record their observations.

Students recognize the importance of plants as they perform an experiment involving photosynthesis. Students determine the optimum wavelength of light for photosynthesis by exposing plants to different colors of light, collecting data, creating a graph from the data, and comparing results among groups.

Students collaborate in heterogeneous groups with each student having a different role. They comprehend the relationship between the frequency and wavelength of light. They record their observations in a table that is included on this lesson plan.

Young scholars understand the difference between the primary colors of wavelengths and the primary colors of paint. In this color lesson, students experiment with various color concepts. Young scholars interview people about their favorite colors and create a graph.

Students engage in a instructional activity which includes flame tests and the construction of a simple diffraction spectrograph with which to measure sodium ion emissions. They use the Bragg equation to compute the wavelength of the line spectra produced.

Learners examine the many types of electromagnetic waves, the concept of an EM wave, how James Clerk Maxwell proposed a slight modification of the equations of electricity, Heinrich Hertz and his radio-frequency, wavelengths, and light emission.

Students investigate the components of white light as viewed through a prism. The multiple colors of the spectrum produced are related to wavelengths and experienced through the creation of a color wheel.
