Awkward Science

Project by group dmsgrayfall2019

Explore Usually if the plant gets more water and sunlight it grows/germinates more than one with less water and sunlight.
Research Question Does changing the amount of water affect how fast the seed germinates?
Predictions If there are 2 sets of plants, one set gets 10 millimeters and the other gets 15 milliliters, then the set that gets 15 milliliters will have a higher germination percentage rate.
Experimental Design We will set up the experiment using the 4 petri dishes and the 20 corn seeds. 2. We will put 5 seeds in each petri dish on top of a paper towel in each petri dish. 3. We will water 2 dishes with 15 ml of water each, and the other two with 20 ml each. 4. We will repeat step 3 every day and water the same amount for each dish we did the first time.
Conclusion Yes, it does, because when we had 10 ml and 15 ml, the 15ml grew 10% faster at the start. We knew that it was the answer because at first, the 15ml seeds were growing faster, but later on, one of the seeds rotted because it got too much water, which lowered its oxygen supply, which caused it to be open to infection. We think that the 15 ml petri dish was the least successful between the two because one of the seeds was rotted and it didn't grow completely.
