The heat is trapped in the city by sidewalks, buildings, roads, and houses. In St. Louis, the city is 15 degrees hotter than in the county at night. This is because the heat that has been trapped during the day is finally able to escape. The picture below shows an example of the heat island effect.
Basil is used for cooking and consumption. Many people grow basil at home. We decided to use basil as a guinea pig for our experiment. We had 2 trays of different soils, sandy loam and Miracle Grow. We planted basil in both of the trays and measured them as they started to grow. There were three different schools with us, and together we made four different schools working on this project. Each school had a different mixture of soil.
We had sandy loam, and it isn't doing to well. There are big patches of gray and yellow and brown on the basil leaves, and the leaves are wilted, not nicely curved as regular basil is. So this is only a small portion on the soils. there are many types of soil in this expirment. the types are sandy loam, clay sand and loam, compost and clay,and clay loam and compost.
Along with the maricel grow which in this case is the control. now that you ,the reader, know what the soils are nw it is time to explain how well they grew plants.
Sandy loam was the best in this case. next up was compost and clay third was loam and clay and finally was sand loam and clay.
On a scale of 1-10 we voted on the quality of the sandy loam soil in comparison to miracle grow: 1 being the worse and 10 being the best
We have two trays of plants. One Gravel and one soil. In which tray do you think will do better? The aquaponics tank is not connected to the soil tray. On the other hand, the gravel tray is connected. That is very important for the plants in the gravel tray. Here is why:
We have been learning about fish environments, plants, pH, nitrates, nitrites, KH, ammonia, bacteria, molecules, and macronutrients. We learned that our goldfish give off ammonia, and that is good for plants when the ammonia bacteria eats it and turns it into nitrites. Then, the nitrite eating bacteria eat the nitrites and turns into nitrates which is beneficial for the plants. The gravel and aquaponics environment produced healthy, enormous, gigantic, beautiful plants compared to the soil only environment
Our main focus was on the kale in both trays. We watered, measured, and took care of them. When we first received them they were very tiny. Over time they began to grow very quickly. The gravel tray with the kale grew quicker than the soil ones. Our kale is green and it has a tint of purple. It has ruffles in the leaves and it is very similar to the mustard. It is very difficult to tell the two apart, they are both green and purple.
On March 8,2017 we harvested our kale plants. We dug the kale out of its trays with forks. It was hard to dig them out , because the roots were connected. After we dug them out we measured them. We measured the roots and the plants by themselves. It was fun to watch them grow and harvest them. this has bbeen a n amazing journey. I absolutely cannot for whats next.
Guided by Missouri’s Next Generation Science Standards, a team of five children in grades 4-6 from
each Alliance School will undertake challenging, hands-on projects in an after-school program that
willthe meet once a week for the entire school year.
Besides acting as ambassadors to their own schools, presenting what they learn to classes of their
peers, children will create blogs and videos, offering lessons in sustainability, science and
technology on-line, as seen through the eyes of children.
The method of instruction will be experiential and exploratory, with children helping to develop
hypotheses, design the experiments to test them, carry out the experiments, and present their
results. The sixth graders will help the younger children on each team in the most challenging tasks,
and the entire team will develop simple teaching materials—art work, banners, and filmed
skits—to help even younger children learn from their experiences in the program.
Hands-on shared activities will also result in team-building and networking between Alliance
Schools and SLU, which is a priority for future activities of the Green House Venture.
