Medium and Dye Trace Study

Research Question: Which medium distributes the media most effectively?

Procedure: I will put two drops of blue food coloring into a small clear cup, three with each different media in it and 150 Ml of water then I will see which media gets the bluest to see which one works the best.


Data: Perlite distributes the media most effectively.

Conclusion: I think the perlite absorbed the blue the best, it is also lighter than the vermiculite and cocoanut fiber so the roots will float freely in the perlite.
