The Report-Colored Cups on Brussels Sprouts Germination

Colored Cups on Brussels Sprouts Germination
For a few weeks, we have been doing our germination project. The project was to see how tall the selected plants will grow in a few weeks (this is also our first project of the year). There are 8 groups in total, and we are team 7! In our project, we are doing a brussels sprout experiment where colored cups are placed over seeds to see if the colored light made will grow faster. Originally, we were going to use colored saran wrap and poke holes in them. However, Mr. Bursch did not have saran wrap. When we all went to the stores, they had run out of colored saran wrap. So, we had to improvise. Instead of putting colored saran wrap on top of the cups, we put colored cups (that Anthony so thankfully provided) on the brussels sprouts and poked holes in those. We were wondering where to put the plants, and Brendan came up with the idea to put the cups in a cardboard box. We then agreed to put holes on the bottom of the cups to let out excess water. We put 3 pink cups on, 3 green cups on, and 3 without cups for a control. Everyday, we took off the top colored cup. Brendan then measured the height of the plant with a ruler. Afterwards, Hunter then wrote down all the information that we had received. Then, we put the cups back on and used the tape on them. Because he is the tallest, Scott put them back on the shelves when we finished. We lastly decided that Bryce would make the blog and make the first post. He then added the other 4 people onto the blog. Hunter, Scott, and Anthony were admins, and Bryce gave Brendan Authorship (which made Bryce admin). We decided that we needed to measure the plants in classes, as that were On the first day of checking them, the pink cups were 1,” 0,” and 2,” the green cups were 0,” 3,” and 2,” and lastly the control cups were 1,” 1.5,” and 1.75.” On the second day of checking the plants, the pink cups were 2.25,” 3,” and 3.75,” the green cups were 0,” 4,” and 3,” and the cup with no lid was 3,” 4,” and 4.” On the last day of checking them before Mr. Bursch took the plants, the pink cups were 3.75,” 4,” and 3.75,” the green cups were 1.5,” and 4.5,” and lastly the cups without a lid were 3,” 4,” and 4.” The plants were shamrock green, but it seemed that the smaller ones were of a bit lighter green color. Also, some got so big that they flopped over! This proved our hypothesis to be correct. We predicted that the plants with the green cups would grow the most. We would have pictures, but Mr. Bursch sadly took the plants to a better place to be grown. He took them to be outside to grow more, however a week later, we planted one of ours in the garden, so we can see how big it'll grow there. We planted our biggest plant, at 4.5 inches, which is crazy! When we looked at our results, it showed that the cups without anything and pink cups were around the same height, however green is slightly bigger by an inch at the most. However, it also has the smallest sprout at 1.” So, it seems like pink and no cups are basically the same, and green cups can either stunt the growth, or make the plant grow faster. The first day, the mode was 1 inch,the second day was 3 inches, and the third day 3.75 inches and 4 inches (it is a tie at 2 plants). The mean for the first day was 1.361 inches, the second day was 2.6 inches, and the third day was 3.6 inches. The median on the first day was 1.5 inches, the second day was 3 inches, and the third day was 4 inches. The range for the first day was 3 inches, the second day was 4 inches, and the third day was 3.5 inches. The smallest one we ever grew was 1 inch, and the biggest plant was 4.5 inches. Out of the 4 types of cups, the pink cups seemed to of grown the tallest of them all. The final height of the pink cup plants combined were 11.5 inches, the green cups were 9.5 inches, and the cups without tops (the control) were 11 inches tall. We later wondered, what will happen if others use this experiment? We also wondered if the future experiments will have relatively the same results, or what if they have very different results? We also thought, "what if future studies put a lot more money into the project, to build it on a bigger scale?" However, those questions can be solved in the future. For now, let's just hope our experiment was sufficient for the time being, and that our brussels sprouts grow!
