Effects of Dietary Supplements on Brown Planaria

CSEF · 2019 Zoology

Christian E. Mueller · American Martyrs School, Manhattan Beach, Los Angeles County

Overview

Objectives Measuring the regeneration rate of planaria after being introduced to several different dietary supplements. Methods One hundred and five brown planaria, seven petri dishes, two milliliters or milligrams of zinc, protein, sugar, vitamin E, vitamin A, and vitamin D3, and a metric tape measure. Tested the difference in planaria's regeneration rate when introduced with different dietary supplements. Results After being introduced with different dietary supplements, every planarian shrunk in size, all except the control group. Some vitamins did more or less harm than others. Conclusions As shown from my results, all of the supplements decreased the planarians' length, which was not what I expected in my hypothesis. In conclusion, the dietary supplements that I tested harm planaria and their regeneration rate.

Summary statement

I tested to see whether dietary supplements boost planaria's regeneration rate or not and by how much.

Help received

I received some advice from my science teacher, who also ordered the planaria.
