    Access is an AACT member benefit. Lab: Test Tube Geology Mark as Favorite (9 Favorites)

    In this lab, students will observe a reaction between an iron nail and copper(II) sulfate in a test tube over the course of several days, modeling how a similar reaction occurs to form copper deposits in the earth. Students will also modify the procedures to evaluate how changing a factor of their choice affects the results of the test tube reaction, introducing them to concepts of experimental design. It also introduces students to my version of the Science Writing Heuristic (SWH).

    In this demonstration, students will observe a reaction between baking soda and vinegar in the presence of a variety of different heights of lit candles. The initial environment has plenty of oxygen present in order to sustain the candle’s flame; however the reaction will produce carbon dioxide which will cause the lit candles to extinguish in order of height. Students will analyze and compare the presence of the gases in the container and make determinations about the densities of each.
