I wonder if the amount of fertilizer affects how much more the crops grow?
It looks like most crops grow a lot with some fertilizers but with too much, the crop can't get enough nutrients it needs.
In school researching
I have came to the hypothesis that 100 milliliters of fertilizer will make the crops grow the most because 50 milliliters will probably not make them not grow as much and 150 milliliters is too much for the crops.
Form a Hypothesis
In school forming a hypothesis.
Perform the experiment
My independent Variable is the amount of fertilizer. (50 ML, 100 ML, 150 ML)
My dependent Variable is how much more the corn grew with fertilizer than normally, with 50 ML and 150 ML.
The constants are, the type of fertilizer and Corn.The control is the normal water given to the fourth field.
I used a line graph to collect all of my date and my results told me that crops with 100 ML of fertilizer added to it grew the most out of all three. The crops with 150 ML of fertilizer made the plants more dead and the crops with 50 ML of fertilizer added was smaller than the crops with 100 ML added. Also the crops with water added to them grew a little bit smaller than the ones with 50 Ml of fertilizer added to it.
In school Analyzing results.
In school Concluding results.
My hypothesis was correct because the crops with 100 ML of fertilizer added to it grew the most out of all four groups of crops.
