The reason we conducted the experiment was to learn how much fertilizer to use on lawn grass, and how it affects grass. We found in the research that fertilizer helps the plant grow (with the right amount) in long amounts of time. Our hypothesis was if we change the amount of fertilizer in the grass plants soil than the amount with 1 tsp. will be the tallest and healthiest, because it will not be too much or too little but just right. To create this experiment we filled cups with soil and poked holes for the grass seeds. Then we watered the seeds and added the amount of fertilizer needed to each cup. An answer to our question is that fertilizer does affect plant growth with the right amount of time needed. In our experiment the plants without …show more content…

Another qualitative observation made was that the grass grew slanted and towards the sun. A quantitative observation we made was that the grass with 1 tsp. and 2 tsp. of fertilizer had 7 strands of grass growing in the cup. Our hypothesis was not supported, we said that the 1 tsp. would grow the tallest, when in reality the cup without any fertilizer grew the tallest most healthiest grass. We think it was because the fertilizer that we used needed a bit more time to activate, not just a week or two. One uncertainty were that in our next experiment we would have liked to have more time for the plants to grow. Another uncertainty was that we only did one of each amount of fertilizer, which could make the results less accurate. Some questions that we have wondered throughout this experience is, “what if we use the same amount of fertilizer on other types of plants?” and “I wonder if other people have done this experiment before, and what were their results?”. In our next experiment we plan to use different types of fertilizers and plants, so we can see how they are affected as well. Society can benefit from this experiment in many ways, one way is people learned how much fertilizer is really needed for grass, instead of just looking at
