My PBL Project By: kyle irwin

The overview

In the 21st century there are several individuals in communities and globally that struggle to have a hot meal every day. In a community financial challenges may allow individuals not to have a meal, While on a global basis environmental issues such as deforestation, desertification, lack of water and water pollution may also be a challenge for the citizens of a country in growing crops for food. Lack of food can result in malnutrition that can finally lead to death. It is said ‘give a man a fish and you feed him for a day; teach a man to fish and you feed him for a lifetime." Our driving question for this quarter is how can we as CMS students demonstrate how to solve food challenges locally and globally.


For my math section of this PBL we looked at the mathematics of building an area for the garden. We went out to our garden and measured all the planter boxes. The garden looks like the picture above. The red shapes are the original sizes. We were given a math journal to fill out. In the journal there was space to record all of the measurements and data we found out. We needed to find out the area and volume of the pots and planters. We also needed to find out how much it would cost to build and plant our garden. From this I discovered that it cost a lot to build a garden. Also I learned that subsistence farming could make a garden cheaper.


For the science section of my PBL Project we grew radishes. We did this to see what it would be like to grow your own crops. It started when a select few in my class got a star. They received a piece of candy and better soil for the radish. I was a part of the star group. We tested different colors of light with the radish to see which one would grow the best. My class got a blue light.

While growing our radishes we had a few problems. My group was watering our radish to much, and then we were watering it to little. We also had thanksgiving break while growing our radish. During this we had a hard time watering the radish because we couldn't get to it. By the time we got back, my radish wasn't doing so well.

When Ms.Sinclair said we would be growing radishes I was so excited. I have always wanted to plant things and have a green thumb, so this was a perfect opportunity. From this I learned that growing a radish was not an easy thing to do. It requires a lot of care and attention.

After planting my radish, I have found out that water and light color have a lot to do with plant growth. Water is a necessity for all living things. To much water will prevent your plant from growing, and to little will shrivel up your plant. As you know, plants are usually green. This is because of a pigment called chlorophyll. This pigment absorbs a lot of colors, Red, blue, and purple, and it reflects the color green. A plant wouldn't do so well if it was under green light because it is reflecting it. We could increase the rate of plant growth by using a blue or red lighting. We could also water it so that stays moist.


My goal is to find a way to solve food challenges in my local and global communities. My family and I are on our way to Africa when our plane fails and we go down. It is my job to chose a crop or a number of crops that can grow in the area where I have landed.

The humanities part of my PBL was about a simulated plane crash somewhere in Africa. Where ever I landed I would pick a few crops that could grow in the place I landed. I landed in The Congo which is in the center of Africa. it is a rain forest so there is a lot of rain and a lot of wild life. The 3 crops I chose to grow were pineapple, radishes, and bananas.


I chose pineapple as a crop because it is a tropical plant. You can really grow pineapples anywhere. They adapt to their environment very easily. The soil of a rainforest is not very good. Luckily, pineapples belong to the family of bromeliads, and like all bromeliads they do not have a big root system. Meaning that they do not need good soil. They take about two 2 years to harvest, but they are 452 calories, and have 119 total carbohydrates.


The next crop I chose was radishes. Radishes are supposed to be really easy and a great starter crop for beginning planters. They grow well throughout the year and only take 23-70 days till they are ready to be harvested. Radishes give you 2 grams of carbohydrates, 12 Calories , and .35 grams of protein.


The final crop I chose was bananas. I think bananas would be a great fruit to grow in a rainforest. Banana need a subtropical or tropical place to grow. They also need a lot of water which a rainforest would give it. They grow high up so they will receive a lot more sunlight since they are above the canopy. They take about 9 months to grow, but they will produce a lot of bananas during this time. 1 banana is about 105 calories, has 27 total carbohydrates, and has vitamin A, vitamin C, and magnesium.


Several people struggle to have a decent meal everyday. Food challenges are all over the world. A way we could solve this challenge is by having some people participate in subsistence farming. Subsistence farming is when you farm just to provide basic food needs for you and your family. Another way is by creating community gardens. This way you could not only help your family, but your neighbors and friends. In the end we all need to work together to find a solution to fix this major problem.
