Data Graph: Create a graph using your own data. The Y axis represents your Dependent / Outcome variable, the X axis represents your Independent / Test variables. You can create a graph that shows all of your data or you can find the average for each test variables trials.

Analyzing the Results:

Explain the average results for each of your test variables.

Conclusion:

  • First paragraph – State your conclusion and summarize your results in a few sentences to support this conclusion.
  • Second paragraph –State if your results support or contradict your hypothesis. If appropriate, state the relationship between the independent (test) and dependent (outcome) variables.
  • Third paragraph - Summarize and evaluate your experimental procedure, making comments about its success and effectiveness. Suggest changes in the experimental procedure (or design) and/or possibilities for further study.

Display your project:

Two choices – a Tri-Fold board display or a PowerPoint Presentation (Prezi is also acceptable)

Your Tri-Fold display must follow the layout below:

A Power Point Presentation must have a minimum of the following slides (in this order):

Slide 1 –Title, your name, teacher’s name, class period

Slide 2 – Questions

Slide 3 – Test Variables (and control if it applies)

Slide 4 – Constants

Slide 5 – Outcome Variable

Slide 6 – Hypothesis

Slide 7 – Experiment Materials (include pictures) Use as many slides as you need.

Slide 8 – Experiment Procedures (include pictures) Use as many slides as you need.

Slide 9 – Data table

Slide 10 – Graph

Slide 11 – Results

Slide 12 – Conclusion
