Business Technology Early College High School Fertilizer Lab Experiment AP Living Environment Mr. Acquaotta/Mr. Lee Purpose The purpose that this lab was conducted was because we wanted to see if seeds germinated faster if fertilizer was applied. Introduction Fertilizer we use it when we garden, we see companies promote it in various ways, but have you ever wondered if it made a difference in growth of plants? Does it really make flowers bloom more rapidly or vegetables grow larger and more productive? The answers to these questions are all within the realm of science because they are testable by controlled experiments, observations and data gathering. Hypothesis If fertilizer is added to different types of seeds, then seed germination will become faster. Materials For this experiment we used the following items; a Ruler, Fish Fertilizer, Miracle Grow, Water, (3)150ml Plastic Containers, a Dropper, a Karter Scientific Pipette, (3) Plastic Plant Pot Trays, Potting Soil, Oregano seeds, Wheat Cat Grass seeds, and a Spread Sheet. Variables Our constant (the variable that is never changed) in this experiment was the potting soil. Our independent variable (the variable that is being changed or controlled) is the different types of fertilizer. The dependent variable (the variable that is being …show more content…
I was surprised to see that the fertilizer had little to no effect at all, maybe we could have done something different where it would have been, but we can’t be for sure till we experiment again. This lab taught me that science is all about trial through fire, you can’t just do something once and conclude that “Yes this is how it is”, or “This works” rather we must see that if we get similar results from multiple trials, then and only then can we conclude that it
