Identify oxidation-reduction reactions and justify the identification in terms of electron transfer.ĥ. Justify with evidence the order of chemical reactivity of metals.Ĥ. Make observations involving metals in metal ion solutions with respect to whether a reaction occurred or not.ģ. Predict and/or justify trends in atomic properties of metals based on location on the periodic table and/or the shell model.Ģ. Note, Alex Johnstone stressed instructors should not have students view all three levels simultaneously, but rather "slide" on one side of the triangle at a time.ġ. When the student activity sheet /tutorial is used with computer simulation and the computer animations representing reactions at the particle level (atom level), and when students have the opportunity to do an activity series of metal experiment in the laboratory it is an effective way of exposing students to all three levels of representation in Alex Johnstone's triangle: microscopic, symbolic and macroscopic levels of representation. A student activity sheet developed by Gelder, Abraham and Greenbowe is available to use with this computer simulation and is available to down load. Rather than lecturing students on the activity series of metals why not let the students make observations and develop their own activity series of metals? Students can compare their activity series with the one in their textbook. A new HTML5 based computer simulation of this activity is planned to be developed. This is an OLD FLASH-based computer simulation developed by Tom Greenbowe and his chemistry education research group. ©2010 Greenbowe Chemistry Education Instructional Resources. ***This is a temporary link that will get you to all of the Gelder, Abraham, Greenbowe (GAG) chemistry education instructional resources (including computer simulations). Students will interpret the data collected to construct an activity series of the elements used in this simulation (AACT, 2021). A total of eight metals will be observed in various combinations with the corresponding metal nitrate solutions and hydrochloric acid. In this activity, students will run simulated tests of various metals in aqueous solutions to determine the relative reactivity of these metals. Based on observations, write the the oxidation-reduction half-reactions. Option to view a computer animation at the particle level of the interaction of the M 2 +ion with the metal electrode. Build an activity series of metals based upon observations of whether or not a metal reacts with a M 2 +aqueous solution. Select various metals to test in aqueous M 2 + solutions. ©2021 ACS American Association of Chemistry Teachers Authors: Thomas Greenbowe Univeristy of Oregon, John Gelder Oklahoma State University, Adam Boyd AACT, Monica Wixon AACT Activity Series of Metals Computer Simulation New Version CSS/JAVA
