Determine which of the observations below are testable. For those that are testable:
- Determine if the observation is qualitative or quantitative.
- Write a hypothesis and a null hypothesis.
- What would be your experimental approach?
- What are the dependent and independent variables?
- What are your controls - both positive and negative?
- How will you collect your data?
- How will you present your data (e.g., charts, graphs, types)?
- How will you analyze your data?
- When Sally eats healthy foods and exercises regularly, her blood pressure is 10 points lower than when she eats fatty foods and does not exercise.

Okay pleaseee I need help with JUST choosing 3 variables. I don't need help with the project but I am SO stuck on choosing 3 variables (2 independent and 1 dependant) that are biological in nature that could possibly correlate??? That has me so stuck so any ideas would be GREATLY appreciated. The rest I can do! This is the projects info just so you have a better idea of what options for the 3 variables are suitable! For this...
