I have been developing some new ideas:
1. Conducting an experiment regarding the effectiveness of different chemicals to remove a stain from calico. I will also ivestigate the possible substitute of environmentally friendly methods as opposed to harmful chemicals such as bleach.
Dependent variables
- The type of fabric
- The size and shape of the stain itself
- The utensils used
- The time allowed
- The chemical or substance that is used

Looks good, but I'd reconsider what you think are your dependent and independent variables...
