My groups question was if a plant needs dirt so we put sand and my hypothesis is the plant will not grow as high because sand does not have as many minerals and because it steals the water and I turn yellow for the same reasons. We also planted a normal plant called “controlled ” and it had light water and air also fertilizer and every the a plant needs to live. We manipulated the soil by putting in sand and every thing was normal and we put fertilizer in the sand.
Our controlled is 10 cm and our manipulated is 7 cm and yellow and it is growing straight more then the controlled. the manipulated is growing slower and starting to grow faster at some points and our controlled is growing smoothly
