The hypothesis is that the plants receiving a 4% nitrogen solution will be affected the most by growing the tallest.

You will separate the bean plants into seven groups, label each group with a different level of nitrogen, and water them every other day for two weeks.

You will need 20 clear containers, 2 holding containers, 20 bean seeds, 3 jugs of distilled water, 1 ruler, 1 bag of nitrogen fertilizer, 1 scale, 7 200ml beakers, 1 bag of Pearl Light, 1 permanent marker, and 7 stick on labels.

The results of the experiment showed that the control group grew the best, the .5% and the 1% grew the second best, and the 2%, 4%, 6%, and the 10% died. The control group also weighed the most, and the 1% was the second heaviest.

This science project is interesting because it helps gardeners and farmers grow healthier gardens and more abundant crops.

Variations to consider include using different plants and testing a nitrogen solution larger than 2%.
