Research Question How do acid levels affect the growth and germination of plant seeds?
Predictions We predict that the higher levels of acid, the longer it will take for the seed to germinate, the shorter the height, and the shorter root growth
Experimental Design Set up growth Chambers (method A) Soak the seeds with water overnight and plant them (10 seeds to one dish, 3 dishes.) Make two mixtures of acid, (one dilute and one concentrated) and leave one chamber untouched. All seeds get the same amount of liquid, sunlight, and temperature daily, three groups, one neutral, one with a dilute mixture, one with a concentrated mixture Measure the height and root growth of all 3 groups, when sprout is visible, the seed has germinated.
Conclusion It can be concluded that the more acid pH 4 given, the taller the sprouts will grow, with weaker stems. The reason we came to this conclusion is because chamber three always had the tallest sprout, until the last day when it tied with chamber two. But chamber three did not have the strongest stems, chamber two and one had stronger stems. It can be also be concluded that the more acid pH 2 given, the smaller amount of germination. This is because chamber one had the most seeds germinate, (100%) then chamber three, (72.7%) then lastly chamber two had the least seeds germinate. (36.4%)
