  Day 16 & 17: Identification of Metals: Flame Test Pre-Laboratory
-Laboratory Handout that includes the movement of electrons from the ground to the excited state, electron orbital shapes, and instructions for the laboratory that are to be read over and procedures established before students can conduct the laboratory

Identification of Metals: Flame Test
    The laboratory is designed to accompany the idea of electrons going into their excited state. Also, that the coloration will depend on a number of different factors. Different energy is associated with different orbitals, different nuclear contents, varying numbers of electrons, and varying distances from the nucleus.
    The laboratory is set up in stations, students rotate. This limits the amount of materials required and forces students to work at a reasonable pace. Once complete, I conduct the flame test on a set of unknowns in front of the class. Students use their observation notes to determine the identity of the unknowns.
 

     
 

 
     

    Students work in pairs as assigned by Mr. Sklar (determined by the seating plan). This forces students to learn to work with who ever they have been assigned to work with, allows students that do not typically talk the opportunity to get to know one another, and limits the number of unproductive pairings.
