PBL Project second quarter pbl

Driving question

How can we as CMS students demonstrate how to solve food challenges in our local and global communities?

Science PBL

In science we did a radish experiment for our PBL project. We planted radishes in a 4*4*3-inch pots, in groups of two or three. My group's radish was put under a blue light. Even though the majority of plants died, the ones under blue and red light grew the best. We planted these radishes to get a feel for what it's actually like to plant something and how hard it can actually be.

Challenges for Growing the Radishes

It is actually very difficult to plant food. We ran into many problems and, at most times, we did not know how to solve them. Some challenges were how much we would water our plant or how often we would water it. For my project, I used Ethiopia as an example for a place to grow food. Ethiopia is in the African Savanna, so the challenges there would be much greater, such as too much sun or not enough rain. My group's radish ended up dying in the end.

I think one of the problems of why our plants did not grow was because they did not get the right amount of light. The light would cause photosynthesis, so if they didn't go through photosynthesis, then the plant wouldn't grow at all.

As I stated before, I also think that our plants did not get the right amount of water, and it may have been the main reason for why the rate of plant growth was so low. If we gave them too little water, it would be dehydrated and dry. If we gave them too much water, it would drown and die. A way we could have helped that problem and increased the survival rate of the plants would have been a plan. I know most of us didn't make a plan, or if we did we didn't follow it. We all improvised without thinking and our plants suffered from it.

Math PBL

When we started the project we went outside of the school where we found a garden with five different planters. We measured each planter for the area and surface area. There was one round planter so we measured the circumference and area. We wrote all of our measurements in our packets and answered questions that gave us a feel for how much it would cost to fill up our planters with food. We had to solve proportions to find how much it cost to fill the planters and find the volume for all of the planters in the garden. We solved problems like that for the whole packet. I think that if we use our school garden for feeding people in our local area then it will inspire and carry on into a more global ranking.

Humanities PBL

1. Millet

Millet is one of the many crops that grow in the Ethiopian Savanna. I chose it because it takes the least amount of time to grow, and you could easily make it into porridge. The millet only takes about 2 months to grow.

2. Sorghum

Sorghum is another crop that grows well in the savanna but I want to leave pictures of the actual meal, not the sorghum. The sorghum takes about 3-4 months to grow fully.

3. Barely

The barley used to make this meal was another crop grown in Ethiopia. The barley takes about 3-4 months to grow fully.

4. Wheat

The wheat used to make this meal was also a crop planted in Ethiopia. The wheat takes about 4 months to grow fully.

Growing Crops in the savanna

The savanna can be known as very hot and dry. Plants that would grow there have adapted to shorten their roots in the ground, so they won't have to get as much water as a tree in Georgia. The savanna's sun might be a problem. If you were to plant food outdoors in the savanna it would most likely get too much sun and not enough water to survive. The animals there might also try to take the food.

Nefas Silk lafto, Addis Ababa, Ethiopia is my Example

In humanities, I was assigned to grow crops in Nefas Silk Lafto, Addis Ababa, Ethiopia. It is located in the African Savanna, so growing crops that aren't adapted to the conditions of the savanna would be difficult. The constant sun would be harsh and the rain might not be enough to grow the plant. It would be tough.

Ethnic Groups

Ethiopia's population is highly diverse, containing over 80 different ethnic groups. Most people in Ethiopia speak Afro-Asiatic languages, mainly of the Cushitic and Semitic branches.
