Rainbows can teach us about the visible light spectrum. Learners observe multiple items that clearly display a rainbow to develop better connections. The lesson plan then explains wavelength using a rope to make...

Investigate color, light and excited electrons and produce waves using slinkys. Your high schoolers will observe a continuous spectrum with a prism and an overhead projector. They observe flame tests to identify elements and they observe...

Explore physical science by participating in a visual spectrum experiments. Budding scientists identify the colors in the color spectrum and view the colors in class by utilizing cellophane, flash lights, and other arts and crafts...

Create models of the infrared, visible, and ultraviolet portions of the electromagnetic spectrum. Working in small groups, your class can investigate metric conversions calculations. They will find the length of the waves in nanometers,...

Uncover the science behind the beautiful phenomena of rainbows with a simple demonstration. Shine light through different-sized containers of water as young scientists learn that rainbows occur when visible light is split up into its...

Students investigate the Electromagnetic Spectrum and realize there is energy beyond visible light. They identify parts of the EM Spectrum.

Students study the color of stars. In this astronomy based lesson plan, students observe the colors in an open flame and apply the information collected about color and temperature to the visible light emitting from the photosphere of...

Introduce starting space scientists to the electromagnetic spectrum, expecially the portion of visible light. Teach them about wavelength and frequesncy. Then give them a roll of adding machine tape and a manila folder to make a...

While all light travels at the same speed, each color in the visible light spectrum contains a different wavelength and frequency. Scholars determine the relationship between frequency and wavelength as they complete the activity. They...

Explore the behavior of light waves with a lab activity. Scholars build new vocabulary through experimentation and observation. Using different mediums, they model reflection, refraction, transmission, diffusion, and scattering of light.

Young scholars examine bioluminescence and camouflage of deep sea creatures. In this deep sea creatures instructional activity, students investigate the visible and near-visible light spectrum. They work in small groups to complete a...

Learners perform flame tests on 12 elements. In this flame tests lesson plan, students experiment with elements to observe their visible light spectra emitted as electrons jump from one energy level to another. Learners record their...

Look beyond the light! An engaging activity introduces young scholars to the application of a spectroscope. The lesson is the fifth in a series of six and focuses on the analysis of the elements of the sun.

Students become familiar with the concept of spectroscopy or the study of the interaction of matter with electromagnetic radiation. They prepare solutions and measure absorbance at different wavelengths. Pupils comprehend that mater and...

Your older elementary students investigate electromagnetic energy and the electromagnetic spectrum. They will observe 7 items represented in the electromagnetic spectrum and make a poster of all the things the items have in common. After...

High schoolers investigate the effects of light and temperature on plant growth and development. In this plant growth lesson plan, students use radish plants and cover them with different shades of green and red transparencies and...

Use a container full of water as a prism and show that as light is bent, the individual colors from different wavelengths become visible. This explains why the sky appears to be blue midday, and why as the sun nears the horizon, it looks...

Electromagnetic waves travel though empty space, something no other wave type can accomplish. Young scientists learn more about the entire spectrum of electromagnetic waves. They sort cards and apply their knowledge to create models of...

Young scholars are introduced to the relationship between light and vision. In groups, they participate in experiments to discover how different wavelengths are divided in the visible spectrum. They record their answers and discuss their...
