Science Fair Expectations. Question. Students must choose a question that is testable and measureable. For example: Are biodegradable bags really biodegradable or do they break down and loose strength after being exposed to outdoor elements?
Control: 3 trials with biodegradable trash bags that were not exposed to the elements outside
Experimental: 3 trials with a bag claiming to be biodegradable that was exposed to the elements.
This should be written by your student, not copied from a website.
Each step needs to be numbered and explained clearly.
It may be easier to break the procedure into parts:
1. Set up of experiment
2. Measuring of experiment
3. Evaluation of data
