14 September Science 8 Summative investigation project–Mixing Ethanol and Water

  1. Mindful moment.
  2. Review of previous DSN entries. You should have described the original demonstration, your attempt to replicate it, and the patterns observed in the class data. You should have developed or selected an explanation of the vanishing volume and possibly other observations (temperature increase, bubbles, mixing lines). You should have developed and conducted a test of the explanation. The results of the test should either support or challenge the explanation. Perhaps you tested an idea that was part of the explanation you were considering. Write about the outcome and talk with me.
  3. Preview today’s blogpost.
  4. Create a DSN entry for today. What photo will you take? What sketch will you make? (A sketch of your explanation at the atomic-molecular level would be perfect.)
  5. Questions.

If you have finished part 1 of the project (replicating the demonstration, developing and testing an explanation for the vanishing volume, etc.), you may propose a line of investigation that you find interesting about any aspect of the phenomenon of mixing ethanol and water. Please check in with Dr. F before you try anything.

There are many things to try. Open your mind to something you have become curious about.
