Molasses Lab

Part of Lesson Plan: Solutions, Measurements and Data Analysis - Olson

Activity Overview / Details

This lab will take at least 2 days.  The first day will include making the molasses solutions.  Depending on the focus of the lab, you can approach the making of solutions by percentages or molarity.  Regardless, it is a great way to get the students thinking about solutions and dilutions.  Once the dilutions are made and the smaller test tubes have been place inverted into the larger test tubes, place the test tubes in a test tube rack and wait at least 24 hrs and maybe 48 hours for results.

  The following day or two, students will measure the length of the CO2 gas bubble trapped in the smaller test tubes using a metric ruler.  Students will need to create a graph to compare gas production vs molasses concentration.
