Topic: THE EFFECT OF POWDERED PYRITE ON THE GROWTH OF CHINESE GINSENG Problem: ginseng?

What is the effect of powdered pyrite on the growth of Chinese

Hypothesis: I think that if powdered pyrite is added to the soil in which the Chinese ginseng is planted, then it will enhance its growth. Experimental Design: Controlled variables:

Manipulated variable: Responding variable:

Amount of plain potting soil Size of pots Amount of water Amount of sunlight Temperature of environment Size of plants Amount of Powdered Pyrite Growth on terms of Plant Weight

Materials: Pots (15 pieces) Potting soil (2 bags) Powdered Pyrite (600 grams) Chinese ginseng plants (15 pieces) Weighing Scale Experimental Procedure: 1. Fill fifteen (15) pots with potting soil. 2. Carefully place the Chinese ginseng to these pots. 3. Add the following amounts of powdered pyrite: 20 grams to 3 pots 40 grams to 3 pots 60 grams to 3 pots 80 grams to 3 pots These will make up the following experiments: 3 pots with plain potting soil 3 pots with plain potting soil with 20 grams of 3 pots with plain potting soil with 40 grams of 3 pots with plain potting soil with 60 grams of 3 pots with plain potting soil with 80 grams of

4. Make sure that the location is good for the plants so that they will all

be exposed to same conditions and they will not be disturbed during the course of the experiment. 5. Water all the pots with plain water daily. 6. Two months later, pull the plants and begin gathering data. The thing to be measured is the plants’ growth in terms of weight. Therefore, each plant will be weighed.
