We Love Our Veggies

 

Introduction

 

Your scientific team has been sent to the island of Yonkers. Residents are getting sick due to the lack of natural vitamins gotten from freshly grown vegetables. You look around - all you see in the local newspaper: People lining up for vitamin vaccines due to lack of freshly grown foods. Children are starving. People suffering from vitamin deficiencies. You ask the residents: Why don’t you import your vegetables? The answer: No! No! Too expensive. Then you inquire: Why not grow? The citizen becomes enraged. He says, “Look at our land. There is too much coral in our soil. Some places are just plots of sand. Other areas contain too much rock. We plant, the plants die. Plus our population is growing; more space is needed for shelter.”

 

 

Task

 

Your scientific team needs to help these people. How can they obtain fresh produce?

Your group is going to produce a brochure to show the residents of Yonkers on how to help themselves.

 

 

Process

 

You remember that you read somewhere on the mainland that farmland is shrinking by over 15,000 acres a day. That is loss of almost 6 million acres each year, 3 million to erosion and just poor land management, and 3 million to progress in the form of more homes, factories, and roads.

 

At this time, you are going too thoroughly to work on Define the problem. After filling out this report, send it to me.

 

You are now ready to work on Gathering Evidence of the Problem.. On this part, you must be specific. You need to use sources of data. (Hint: How would you gather data?) This must be handed into me before the next step.

 

Click on Determining the Causes. At this time you will identify what is causing this problem. You can go through some of the resources below. When this has been seen by me and discussed, your next move is to then:

                        Hypothesize and proceed to what the possible solutions could be worked out on the island.

           

            In order to proceed on your hypothesis, it is necessary to have the necessary materials. This will take at least a month. (Hint: Your group must make observations on a daily basis. There is a lot of recording that must be done. This will be checked on periodically by me. Included in your information must be drawings and full explanations.)

>Design is not relevant to the hypothesis

>List of materials and controls incomplete

>Some procedural components generally described but are not replicable

>Safety concerns are not specified, are irrelevant or are not appropriate to the experiment

>Design has general relevance to the hypothesis

>List of materials and controls is nearly complete, missing at least one important item

>Design is adequate to test the hypothesis

>List of materials and controls is complete and some description provided

>Description makes it likely that the experiment can be reliably replicated

Conclusion

Students will be adhering to the seven state standards for science during this project.

Scientific Inquiry

Key Idea 1

The central purpose of scientific inquiry is to develop explanations of natural phenomena in a continuing, creative process.

Key Idea 2

Beyond the use of reasoning and consensus, scientific inquiry involves the testing of proposed explanations involving the use of conventional techniques and procedures and usually requiring considerable ingenuity.

Key Idea 3

The observations made while testing proposed explanations, when analyzed using conventional and invented methods, provide new insights into phenomena.

 

Math, Science, Technology

Standard 1 - Analysis, Inquiry, and Design

Students will use mathematical analysis, scientific inquiry, and engineering design, as appropriate, to pose questions, seek answers, and develop solutions.

 

Standard 2 - Information Systems

Students will access, generate, process, and transfer information using appropriate technologies.

 

Standard 3 - Mathematics

Students will understand mathematics and become mathematically confident by communicating and reasoning mathematically, by applying mathematics in real-world settings, and by solving problems through the integrated study of number systems, geometry, algebra, data analysis, probability, and trigonometry.

 

Standard 4 - Science

Students will understand and apply scientific concepts, principles, and theories pertaining to the physical setting and living environment and recognize the historical development of ideas in science.

 

Standard 5 - Technology

Students will apply technological knowledge and skills to design, construct, use, and evaluate products and systems to satisfy human and environmental needs.

 

Standard 6 - Interconnectedness: Common Themes

Students will understand the relationships and common themes that connect mathematics, science, and technology and apply the themes to these and other areas of learning.
