  1. Materials & Procedure

    Slide 1 - Materials & Procedure

    • STEM Fair 2015
  2. Materials

    Slide 2 - Materials

    • Materials are anything that you use in your experiment.
    • Materials used in the experiment need to be listed in specific amounts and sizes.
    • Keep in mind, you need to write your materials in specific amounts and sizes so that anyone can replicate your experiment.
  3. Materials- Amounts

    Slide 3 - Materials- Amounts

    • Examples of specific amounts could be:
    • Numbers (Ex. 3 paperclips, 5 ice cubes, etc.)
    • Cups (Ex. 6 cups of water, 3 cups of orange juice, etc.)
    • Ounces (Ex. 7 oz. of water, 12 oz. club soda)
    • Pounds (Ex. 5 lbs. of chocolate, 1 ½ lb. of clay, etc.)
    • Tablespoons
    • Amounts are the weight of or number of each material in your experiment.
  4. Materials- Sizes

    Slide 4 - Materials- Sizes

    • Examples of specific sizes could be:
    • Large
    • Medium
    • Small
  5. How would you improve this list of materials?

    Slide 5 - How would you improve this list of materials?

    • One empty plastic soda or water bottle
    • Vinegar
    • Balloon
    • Baking soda
    • Funnel or piece of paper
    • When writing your materials out, ask yourself… Would people be able to replicate my experiment?
  6. By adding sizes and amounts!

    Slide 6 - By adding sizes and amounts!

    • One small empty plastic soda or water bottle
    • 1/2 cup of vinegar
    • One small balloon
    • 3 tablespoons of baking soda
    • One large funnel
    • Remember… Be as specific as you can!
  7. Writing a Procedure

    Slide 7 - Writing a Procedure

    • A procedure is a numbered list of the steps that you will follow to complete your experiment.
    • It should be detailed.
    • Remember, as with the materials, the procedure should be written so that any one can be able to try your experiment.
    • Think of it as a step by step recipe!
  8. What makes this procedure a good procedure?

    Slide 8 - What makes this procedure a good procedure?

    • Gather all materials.
    • Measure 2 tablespoons of plain water, 2 tablespoons of saltwater, and 2 tablespoons of distilled water into each ice tray.
    • Place the ice trays in the freezer and allow water to freeze for 8 hours.
    • Line up three clear plastic cups on the table or counter. They should be in a place where you can observe them easily.
    • Remove the ice from the freezer and place each ice cube into a plastic cup.
    • Keep track of the ice in five minute increments.
    • In your science notebook, note the changes in each ice cube as it melts.
    • Write down the time it takes each ice cube to melt completely.
    • Repeat Steps 1-8 two more times.
