Method

Method: We put 9 cups outside to grow with brussels sprouts in soil in them. 3 have green cups on top, 3 have pink cups on top, and 3 have no cups on top for a control. We water and measure them every time we are in that class.

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!


Key: Green=green cups, pink=pink cups, black=no top cup (control)

Our group planted the brussels sprouts in class Friday. When we came to class Monday we collected this data.
Clear : 1", 1.5", 1.75"

Green: 0", 3",  2"

Pink: 1", 0", 2"\

Most are looking healthy, but a few are not growing at all.

 Our group is doing an experiment on the germination of Brussels` sprouts. Our experiment is comprised of the growth of Brussels sprouts under certain colors of light to either speed up or slow down the growth of the plants. We are using a pink and a green plastic cup to grow the plants in, our control plant did not have a cup over the plant at all to allow all colors of sun light. There is a total of nine plants; three pink, three green, and three control. We know this experiment will go well while growing Brussels sprouts.

Brief Bio

My name is Anthony DiGirolamo and I have lived in San Jose, California my whole life. In elementary school we grew snow peas and beets. I remember having to dig down and plant the seed and to put a stick so it grows the right way. Also watering the plant and making sure it gets sunlight. A person in my life that knows a lot about plants and gardening is my grandma because she loves to garden and she knows about all types of plants. Sometimes we go to the Branham high school flea market because she finds plants that I have no idea what they are.

My name is Scott Hetrick I am 13 years old and I have lived in San Jose, California my entire life. In elementary school we had a class garden and we grew snow peas, lettuce, beats, and a couple more that I do not remember. I remember having to water daily and color a stick to know where we planted the seeds. My grandma is always growing something new her favorites are tomato and roses. When she goes on a trip I have to water all of them so if I do a bad job I am in a lot of trouble and I will get the grandma texture that everyone gets and terrible after.

My name is Hunter Sandahl. I was born in April 17, 2002 in Seattle, Washington before I moved to San Jose, California in 2012.

I used to be part of a school garden before I moved to California. In the garden we grew potatoes and green beans. We would work in the garden every day at school during recess and grew lots of crops that we later picked and brought home for ourselves. I remember that it took a lot of work to properly grow the vegetables to be prepared to pick and eat.

I think that my mom knows a lot about gardening because she used to grow vegetables with my dad. These crops included chile peppers, jalapenos, rose mary, and lettuce. I think both my parents know a lot about horticulture because they maintain all the plants around our house aside from the food that they grew.

My name is Brenden Schriver. I was born in 2002 in San Jose, California. My mom, sister, and grandparents live in Los Banos, California. The rest of my family lives in San Jose.

I used to garden a lot, my grandpa used to work at a farm and my great grandma used to grow all her food from scratch in her garden. I have a green thumb for growing tomatoes. Otherwise i am not a very good or experienced gardener. I used to grow tomatoes a lot, and I remember my great grandma and grandma used to pick all three hundred or so plants between both houses, then we all used to make spaghetti sauce.

The person in my life that used to grow her own food and make it from scratch was my great grandma. She used to grow any type of food you can grow in her small garden. Up until a month before she passed away she still grew tomatoes, basil, onions, garlic and all the other ingredients needed to make sauce and she jarred almost two-hundred jars of spaghetti sauce.

Hi,

my name is Bryce. I live and was born in 2002 in San Jose, California. I've gardened before, but that was in elementary school. My grandpa lives near Los Angeles however, and some of my dad's cousins live in Montana. We visit my grandpa, but not my cousins in Montana.

I grew carrots with my dad at my house when I was 7. My dad helped me grow my carrots as he is great at farming. He adds fertilizer and grew our lawn back by himself when it died in the Summer. I don't know much about farming, but I try my hardest. At my elementary school, we grew onions, beets, carrots, and lettuce. I remembered it was easy, but then again, we had a lot of teachers helping! I liked the carrots and lettuce, but not the onions and beets.

Hi everyone. We are doing a project for Mr. Bursch at WGHS to have a germination project. Our project will be about if different colored light will affect the growth of brussel sprouts. We are calling it, "The Colored Light Experiment." So stayed tuned for more info!
