Elements, Identifying an Unknown, Atomic Spectra, Emission Spectrum, Electromagnetic Spectrum, Emission Spectrum | Middle School, Elementary School
Lesson Plan: Elements Are Out of This World
In this lesson, students will learn about the elements that make up Earth’s atmosphere and lithosphere and then compare and contrast the information with the elements that compose various other astronomical objects.

Electromagnetic Spectrum, Identifying an Unknown | Middle School, High School
Video: Color Matching Paint Video
This video explains how technology, specifically focusing on spectrophotometry, can be used for paint matching. Students will learn how the spectrophotometer interacts with the spectrum of visible light in order to match or reproduce specific paint colors.

Lesson Plan: Understanding Light & Color
In this lesson students use spectroscopes to analyze the colors of sunlight reflected off a white surface, and determine various colors of light emitted by a multicolor LED bulb at different color settings. They predict what color an object will appear when observed under a certain color of light, and test their predictions with the LED bulb. Students explore how a color wheel can provide a useful model for determining the colors of light an object may absorb or reflect. Finally, students will investigate the color yellow. Many objects that appear yellow are not reflecting yellow light, but reflecting green and red. Students use their spectroscopes to search for objects that truly reflect yellow light.

Lesson Plan: Let it Glow
In this lesson students will investigate the fluorescence of a variety of everyday items as well as prepared samples under a black light. Students will examine the concepts of absorption and subsequent emission of photons, as well as wavelength, frequency, and energy of electromagnetic radiation. As extension activities, students will learn about phosphorescence and research real-life applications of photoluminescence.

Electromagnetic Spectrum, Molecular Structure, Mixtures | Middle School, High School
Video: What are Pigments? Video
This video discusses the chemistry of pigment molecules and how they are used to give paints their specific color. Students will learn about the importance of a pigment’s molecular structure, how they are physically suspended to create a paint color, as well as how they interact with light.

Radiation, Electromagnetic Spectrum, Radiation | Middle School, High School
Lab: The Most Effective Sunscreen
In this lab, students will research and compare the effectiveness of various SPF levels in sunscreen lotions. The lotion’s ability to block UV (ultraviolet) radiation from the sun will be tested using a UV bead detector.
-
Separating Mixtures, Interdisciplinary, Separating Mixtures, Electromagnetic Spectrum, Mixture | Middle School
Lab: Candy and Leaf Chromatography
In this lab, students will learn that mixtures are created by the combination of two or more substances. Many colors are actually mixtures of several different pigments. Mixtures can be separated, and in this lab students will perform chromatography to separate mixtures found in candy and in leaves.
