Creating a Salad Dressing Using the Scientific
Method

What is the problem today?

• Can I come up with a sweet salad dressing?
• Can I come up with a tangy salad dressing?

4
Your next step is developing a hypothesis.

• Guess how you could make your salad dressing
  taste the way that you want it to or that would
  answer your question.

5
Now write down your procedure for your first
trial. Make sure you write down the ingredients
that you choose to use for each experiment or
recipe.
6
Start to make the salad dressing following the
procedure (recipe) that you just created.

• Make sure that you measure carefully and
  document the amount of each ingredient on your
  handout.
• If this isnt precise, we cannot duplicate the
  recipe-the recipe will be lost!!!!!

7
Write down the data.

• What happens while following the recipe?
• What does the dressing look like?
• You may want to taste it to check-out flavors
  during the experiment.

8
What are the results?

• When you taste your creation, use plenty of
  adjectives to describe the result. Use many
  senses-smell, sight, taste.

9
What are the conclusions?

• Did you prove your hypothesis? Did you make the
  recipe that you were expecting to make?
• If it isnt what you expected, describe what
  seems to be off, for example, is it too sweet or
  bitter?
• Do you think you used too much of something?

10
Scientists may also repeat the experiment,
changing some of the variables, one at a time, in
order to get different results.
11
Once you have completed three trials, as a group,
choose the one that your group likes best.

• You have the recipe for what could be a new salad
  dressing sensation!!
• Oh yes, by the way, recreate your dressing in an
  amount large enough to be shared with the class
  at the Salad Bar!!!
