Experimental Procedure

  1. State the problem you are going to investigate in this science fair project.
  2. Create the data sheets you will use to record your observations.
  3. Gather all your materials.
  4. Put on your safety glasses, plastic gloves and apron.
  5. Gather all your materials.
  6. Start by cutting a large piece of grass into seven pieces of approximately the same size. Place each sample in a jar. Add five ice cubes to each jar. Label the jars in terms of each of the substances you are testing such as rock salt, calcium chloride etc. Make certain to label the last jar as the control.
  7. Now measure off twelve ounces of each substance to be tested and place each substance in its jar. For example, what you have in each jar is a grass segment covered with ice cubes and twelve ounces of an ice melting   substance.
  8. Observe each one noting how long each took to melt the ice cubes. Record your data in your chart.
  9. Carefully observe the grass in each jar and record what changes occurred. Record your observations compare all of the jars with the control. Record your findings.
  10. Record your conclusion.
  11. Prepare your report and include all of the following: a clear statement of the problem, your hypothesis, namely what did you predict would occur, and a list of the materials used. Include the safety precautions taken. Describe the procedures used. Include all the data that were gathered. Include all charts. Explain the purpose of the control.  Formulate your conclusions.   For dramatic value, you may include photos of the materials used or of you in the process of conducting this investigation. Include a bibliography of sources you used. You may wish to assess what you did and describe what you would do differently if you were to do this project again. You may wish to expand this research next year. What other materials might you investigate for this purpose?
