• The Flame Test

  Flame Test How are elements identified by using a flame test? A metal salt is a compound of a metal and a nonmetal. When dissolved in water, the metal and nonmetal atoms separate into charged particles called ions. As the metal ion is heated by the flame, the electrons gain energy and move to outer orbitals. When the metal ion cools, the electrons go back to their original orbital and release energy in the form of light. Are these colors a characteristic of the metal? In this virtual investigation you will burn a small amount of various metal salt solutions and record the colors of the flames. From your results, you will draw conclusions about the colors released from heated metal ions. You will also test an unknown metal salt and determine what metal is present. Need Help?

  Teacher Notes Additional safety information: The Rainbow Demonstration or Rainbow Flame Demonstration is an activity popularly conducted in chemistry classrooms. The purpose is to demonstrate to students the variety of colors produced when different metals or metallic salts meet a flame. This procedure is an updated version of the traditional one. The traditional Rainbow Demonstration required that a highly flammable solvent, such as methanol or ethanol, be mixed with the metallic salts. Read a Safety Alert from the American Chemical Society about the traditional procedure for this demonstration.

  Add the solid metallic salts to the beakers: Note: if you do not have mL beakers, substitute another piece of glassware and use a 50 mL graduated cylinder to add the deionized water. Use a separate wooden splint to stir each of the solutions. Distribute the remaining wooden splints between the solutions. Allow the splints to sit in the solutions overnight. Alternate options: If you cannot find wooden splints you can substitute generic cotton swabs, or longer craft swabs. Soak wooden splints or cotton swabs in deionized water for a few hours and then dip them into small samples of each solid before putting them through the flame.

  Changes of energy and matter in a system can be described in terms of energy and matter flows into, out of, and within that system. Introduction In this lesson students heat a number of metallic salts in a Bunsen burner and compare the colors that emerge with known colors of different elements. The goals of this lab are to give students a way to interact with atoms and electrons, to introduce the idea that electrons have wave-like properties, and to engage students. This lesson aligns with the NGSS Disciplinary Core Idea of HS-PS , Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms because it emphasizes that "Each atom has a charged substructure consisting of a nucleus, which is made of protons and neutrons, surrounded by electrons.

  This lesson aligns with two NGSS Practices of the Scientist-- SP3, Planning and carrying out investigations and SP4, Analyzing and interpreting data because students conduct an investigation and then wrestle with the data they collect. While students do not need prior knowledge to conduct the lab, this lesson asks students to calculate the frequency of the light emitted from the electrons as part of the post-lab questions.

  Advance teaching of this optional material such as happens in this lesson would ensure that there was enough time on lab day for students to focus on collecting and interpreting the data. Students should know how to use a Bunsen burner. If they have no experience then they should receive explicit instruction before the flame tests as to how to light , adjust , and work safely with them. I use this website as it gives a good overview of the procedure as well as the cause of the colors that are emitted and what the colors may indicate. Students take what they have learned about the procedure and create a cartoon of the procedure, which causes them to not only read the procedure, but also to begin to process the meaning behind each step in the procedure. Students use the flame test cartoon graphic organizer so that they are using a common format, which will make discussing the procedure easier.

This seems like a good choice because today's lesson focuses on how colors are produced in fireworks. A video that shows how I discussed the speed of light formula and what my rationales were for the lesson can be found in this Classroom Video: Responding to Data with Reteaching. Guided Practice: Once I have reviewed how to use the speed of light formula, I know that students will need to learn how to use their calculators with scientific notation.
