Corny Soybeans

Project by group nebuzzellspring2019

Explore We know that plants grow on land and in water. We also know that some plants are edible, and some are not. Plants come in different shapes and sizes. We learned that plants can’t have too much water. How do seedless plants grow? What is the difference between corn and soybean plants? Will a seed grow in a cup and water and light?
Research Question Will giving plants 24 hours of artificial light make plants grow faster than 12 hours of sunlight?
Predictions If, we shine the natural light on the seed for 12 hours and the artificial light for 24 hours, then their growth will be the same because natural light is more powerful, but we will shine the natural light less than the artificial light.
Experimental Design Materials- Lamp, soil, 8 pots, 8 corn seeds, 8 soybean seeds, water, sun, tape, and Sharpie Procedure- Four pots, one has two soybean seeds, one has two soybean seeds, one has two corn seeds, and the last one has two corn seeds, will be in the sunlight next to the window. The same setup will be next to a lamp which will provide the artificial light. The two plants in each pot will be planted one inch down and 3 inches apart. To water the plants, we we will see if the the soil is dry. If it is, we will water the plants.
Conclusion We thought that if we put the plants nearer to the sun, that they would grow better than the plants We put near the lamp. At first, this was not the case. But, as the project went on, the plants at the lamps growth slowed, while the plants at the window kept growing. We found out that, plants growing with the sun is better and more efficient than plants growing without the sun, or less sun. So, the hypothesis We did was correct. Our data showed that the window plants grew taller than the non-window plants. Such as Corn #1, which was over 5 cm taller than Soybeans #4, the tallest non-window plant. And, the tallest plant, Corn #1, was over 30 centimeters taller than the shortest plant, Soybeans #3, at the lamp. We got these results because the sun is a stronger light source than a lamp, even though the sun is 93 million miles away, just goes to show you the power of the sun. The reason that the lamp plants had less colour then the ones by the window, was because maybe the sun has something to do with hydration in plants. We think that the window plants did better than the lamp plants because of the higher concentration of oxygen outside. These results mean that water definitely has something to do with plant growth. Watering the plants seperatlely could’ve messed with our results because we did not know if they are getting enough water. We forgot to measure our plants on April 2nd, so possibly that date could’ve been important to the data. We could have improved our watering skills, and known when a plant needed and did not need to be watered. We would like to know more about the effects of sunlight on a plant, because plants are an integral part of our ecosystem, and we need them to produce the oxygen we breath. Knowing the amount of water to use will help us to not drown or dehydrate the plants. We should redo the experiment so we can fully know and understand the differences in light on a plant.
