You will be given a small amount of 4 white powders on your cardboard. On the black cardboard using a magnifying glass look at the powders.

  1. Hi Jesse

    This looks really great for your white powders blog post. The only part missing is under the chart it asks for you to share your findings in a paragraph format. Please work on writing a short conclusion that you can put here. Then you will have earned your point.
