QUESTION Can a plant survive if it is watered with an alternative liquid?
AIM We want to know with which alternative liquid the plant grows better (coffee, vinegar, milk).
HYPOTHESIS We think the plant with coffee will grow the best, the one with milk will have mold, the one with water will grow well, and the one with vinegar will wilt. We are trying to make the first plants, the ones we kept, revive, by watering them with water. We think it will partially work.
PROCEDURE • We bought 3 plants, we took one each and we started watering them with an alternative liquid, we did this for about 2 weeks, and then we started doing the second part of the experiment. • This second part consists in buying 4 more plants, and watering them with the same alternative liquids. • We decided to do it like this: we keep the plants 5 days each and we exchange every so often. In the meantime, we started watering the old plants with water to make them revive.
MATERIALS AND INSTRUMENTS Seven plants, four liquids, four bowls to contain the liquids for the plants, a chart which is also a calendar
DATA ANALYSIS We will analyze our data with a chart, a calendar, a powerpoint, and a poster.
OBSERVATIONS We observed our old plants and we realized that the plant watered with coffee became even better than when we bought it, the one with milk formed a lake of mold on the soil of the plant, and the plant watered with vinegar wilted, the leaves and flowers became of a reddish color, the new ones seem to make the same impression as the first ones.
COFFEE Variable 1: We bought the plant for the coffee on the 17th of October, it was an Azalea like the others. Immediately we realized that it was growing better than the others and the buds started even to open. Now we’ re watering it with water and it’s starting to get shoal. We gave it 70ml of coffee and now we are giving it 50ml of water.
COFFEE Variable 2: We always gave the plant 50ml of coffee, this way it developed it self growing up. We observed that if you touch the leaves they are harder that the others. We discovered that the coffee plant is the quickest to absorbe the liquid.
MILK Variable 1: The plant with milk just after a week from the purchase started to mold. The flowers and the twigs started to sag and the petals became more opaque and convulted. Our opinion is that the plant could survive but all the flowers would fall.
MILK Variable 2 : We always gave the plant 50ml milk. At the start the plant was growing, but after about a week it had a decay. The flowers became glossy white and the leaves became dumpish. The plant doesn’t absorbe the liquid very fast so the milk that remained became creamy.
VINEGAR Variable 1: The alive leaves have an odor that reminds vinegar. Their odor is brownish that tends to gray. The plant is flexible, but if you rub it it will crumble. The dead leave’s colour is green-red.
VINEGAR Variable 2: We gave the plant 50ml of vinegar. After 5 days one flower withered, and the day after all the flowers had the same decay. The flower became white-reddish. The leaves became very very dumpish, for the plant it was harder to absorbe the vinegar.
WATER Variable 1: We watered the Azaleas with the alternative liquids, we saw it wasn’t going well, so we decided to try to rivitalyze them.
WATER Variable 2: We always gave the plant 50ml. The plant obviously stays well but we realized that the one with coffee is more vital. The plant is flexible and the twigs branchout in all directions.
