Wheat Grass Lab Report

All in all, this was a very fun and hands on experiment. The abiotic features, such as, the water and the soil, had drastic changes to them as well, and the biotic features; such as, the wheat grass and the anacharis plant, were majorly affected in this experiment, our hypothesis was that we thought that we could neutralize laundry detergent, vinegar and distilled water, so that there won’t be any difference in the growth of the wheatgrass, and the health of the anacharis plant between the control bottle and the two test bottles. We were also observing if one type of vinegar/laundry detergent solution polluted the water more that the other. We made the prediction that the white vinegar would pollute that water more because apple cider is made from more natural substances. My group and I were incorrect, about our hypothesis, but the prediction about the pollution was correct. Both of the wheat grass plants from both of the test columns eventually died.

For example, by day 5 the control bottle has already grew to about 9 cm tall, the white vinegar was 5.5 and the apple cider was 6 cm. The control did very well during this whole experiment growing an average of 2 cm per day, the white vinegar bottle grew about 0.6 cm per day until day 8 and the apple cider vinegar test grew about 1 cm per day until

We noticed that the white vinegar was more polluted by the 5th day. The white vinegar was the most polluted out of all three bottles. We noticed by the 8th day the two test bottles have gained almost an unbearable odor, and the anacharis plant started to decompose in the white vinegar column, which most likely caused the growth of another living organism, mold! So, there is more evidence that the solutions affected the biotic and abiotic components of the 2 test
