Research Question |
We would like to test the ideal liquid for the greatest germination success of Grandma Hadley's Lettuce. We came up with this question through conversation about various plants and what they need in order to germinate. We previously learned that seeds do not need sunlight or soil to germinate, only water. This sparked our interest in how the seed germination could be affected by using various types of liquid. |
Predictions |
We predict that the seeds with the tap water will germinate at the highest rate. We think this because, of the other three forms of liquid, tap water contains the most minerals that would be needed to help the seeds germinate. |
Experimental Design |
Materials Needed:
Grandma Hadley's lettuce seeds, 6 per pot (24 total seeds)
4 plastic dishes
Distilled water
Tap water
Vinegar
Salt
Filter paper
Controlled light |
Conclusion |
Based off of our data and observations over a two week period, we concluded that the distilled and tap water were the better forms of liquid in Grandma Hadley's lettuce seed germination. While only two sprouts were observed out of the 24 total seeds, one in distilled water and one in tap water, we concluded that the vinegar water and salt water were not able to sustain germination. Therefore, we conclude that Grandma Hadley's lettuce has the best germination in distilled water and tap water. |
