Here are the "must-haves" for an effective Physical Universe investigation:

  • Most of the projects submitted in this category will be traditional scientific investigations. Use of the Science & Engineering Practices is expected.

  • Please include a log of your progress through your whole process. This can be in electronic form or using a log-book.

  • Your display should summarize all of your work through the process and needs to highlight each step in the scientific method.

  • Please include graphs and/or images where appropriate.

  • Include materials lists, cited sources for research, procedures, etc.

"Science is a dynamic and iterative process which is not adequately represented by simple linear recipes."

The diagram below, produced at UC Berkeley, is a more accurate view of how scientists do their work than the traditional scientific method.
