DO PLANTS NEED WATER TO LIVE?The aim of this research report is to determine if plants (in this experiment is green bean) need water to live or just need to be kept wet.Background research: Hypothesis: if the plants are being keep wet daily by the same amount of liquid and grown in good conditions of sunlight, air, temperature, ect. Then the plants will grow normally and be healthy.Lists of equipments needed to perform the experiment: 3 pots 1 marker 1 measuring cup 1 rulerGlovesSafety goggles1 camera1 pencilLists of materials used up in the experiment:9 Green beans Soil2.5 litres of Water 2.5 litres of Coke 2.5 litres of MilkThe independent variables of this experiment are the sunlight and the temperature where the pots are placed.
The dependent variable of this experiment is the growth of the plants in terms of their their height and the number of leaves grown measured in each day. The controllable variables are the number of green beans, the amount of soil and the amount of liquid (water, coke and milk) used in this experimentRisk Broken pots ? always keep the pots in the middle, safe place Pets (especially cats or dogs) may dig soil in the pots => always keep the pots in the high placeUsing hand for the soil => wear gloves while doing the experimentSoil flicked onto eyes => wear safety goggles while doing the experimentMethod: Label the containers “water”, “coke”, “milk”Fill the containers with potting soil and plant 3 seeds in each of the potsMeasure out 125ml of water and give it to the plants in the “water” potMeasure out 125ml of milk and give it to the plants in the “milk” potMeasure out 125ml of coke and give it to the plants in the “coke” potPlace the plants in a warm, sunny place outdoors or in a windowRepeats the 3rd, 4th and 5th steps 4 times each day.Record the growth of the plants on the charts belowResults Height Water Milk Coke Day 1Day 2Day 3Day 4Day 5Number of leaves grow each dayWater Milk Coke Day 1Day 2Day 3Day 4Day 5Conclusion DiscussionBibliography
