Mung Bean Experiment

Mung Bean Science Fair

Experiment Group

Introduction & Methods:

I will be testing if there is a direct effect on mung bean growth based on the light it receives for energy. My control group are the mung beans placed in natural sunlight and my experiment group are mung beans placed under a grow light for the same amount of time that there is daylight. Each group will be placed in petri dishes on damp paper towels and covered with damp paper towels. I will be monitoring the germination of the mung beans to assess the rate of growth, every 2 days I will add 2ml of water to ensure that they stay damp.

Grow light

Results:

Null Hypothesis: There is no difference in germination root length due to the source of light.

Control Group

The mung beans in the control group germinated at a slower pace and didnt grow long in length before dying off. The mung beans in the experiment group grew at a faster rate, as well as more beans sprouting, they grew significantly longer in length. The experiment group beans also lasted longer in the growing process. This led me to my alternate hypothesis; there is a difference in germination root length due to the source of light received.

Alternate Hypothesis: There is a difference in germination root length due to the source of light.
