About the Experiment

Experiment Title: What type of seed grows the fastest?

Conditions:

1. red bean
2. mung bean
3. sugar snap pea
4. sweet corn

Experimental Predictions:

I think the red bean will grow the fastest because its coat is the least firm. I think it will be easier for it to sprout because of this.

 

Experiment Methods and Procedure:

I set up three trials. Each trial contained one of each type of bean placed on a moistened papper towel inside of a ziploc bag. I stapled the baggies to prohibit the beans from falling to the bottom of the bag. I taped all of the bags to the wall near the lamps one below the other. Each class session, I removed the bags from the wall. I examined each bag and compared them to each other.

Results and Conclusions:

My predictions were inaccurate. The red bean did not groww the most in any of the three trials. In class we discussed that some of the red beans may have been "duds", perhaps this was the case. I also noticed that even though the trials were set up identically, one seemed to be far less successful than the rest. The bag that was positioned lowest on the wall barely grew at all. I guess that this is because it may not have had as much exposure to the light as it needed. I have retaped the bags in a different order to see if that helps. Next time I might tape them side by side rather than at different heights.
