Parameters/Logistics (for faculty, specific parameters or logistics when implementing)

(Do not remove, standard for all courses) The assignment must be collected through an “Assignment” contentitem in Blackboard. Faculty electing to use Turnitin may do so, but students will need to submit thedocument twice: first to the Bb “Assignment” content item and second to Turnitin.

(Do not remove, standard for all courses) The assignment assesses an outcome included in the syllabus forthe course; thus, all assignments should be included as a regular grade in the course. The assignment shouldnot be considered optional, extra-credit, or a bonus activity.

Criterion Design (How does the assignment ask students to perform in the manner expected by the criterion?)

Explanation of Issues

In both the Phosphorous Test Question C and the Potassium test, Question C students must suggest mechanisms to solve soil deficiency problems. Students must also clearly state the role of potassium and phosphorous in plant anatomy and physiology.

Evidence Students must accurately obtain raw data from the soil test # 6 results from sifting, weighing and convert mathematically into percentages. From these percentages, students must further interpret the soil type by correctly graphing the % lines.

Influence of Context and Assumptions

Part 6 Percentage Test, Question C : Students must assess the environmental condition that is best for the proper growth of root crops. This implies a basic knowledge of the needs and growth patterns of specific examples.

Student’s Position Part 8 Percolation Question D: Students must propose 2 opposing effects on any plant sitting in a watery environment with a clear explanation supporting each.

Conclusions and Related Outcomes

Part 6 Percentage Question B: Students must base a soil conclusion by correctly calculating and analyzing the data obtained in the Percentage soil test procedure.

Criterion Design (How does the assignment ask students to perform in the manner expected by the criterion?)

Context of and Purpose for Writing

In pH Test # 1, Question B requires a statement and explanation of the pH scenario for plants indicating a clear understanding of pH effect on soil. In Test #2 Phosphorous Question D: students must specifically and clearly state the deficiency conditions seen in depleted Phosphorous.

Content Development

In Test # 3 Nitrogen Question B: Students must connect and develop the relationship between the soil content of Nitrogen with the specific need and use by plant parts.

Genre and Disciplinary Conventions

Students are required to complete all 8 tests and fully fill-in the 8 question/answer pages.

Sources and Evidence

In Soil pH Question B; Student are required to cite text, horticulture journals, papers, etc. Students must use/interpret references to respond to specific pH scenarios.

Control of Syntax and Mechanics

Students will complete all questions with clear, full sentence structure + correct grammar.

Readability of Visual Elements

In Test Horizons, Question D, students must observe their test tube results + convert them into a visible drawing with proper distribution and coloration of different horizons.

Relevance, Accuracy, and Integration of Visual Elements

Students will interpret the colorimeter charts to obtain results on Test pH, Phosphorous, Nitrogen and Potassium. Students must calculate mathematical %’s of soil types and integrate the scores into a triangulated visual soil type chart.

Further: Students must propose another mathematical method to calculate Percentages of the different soil deposits layered in the Horizon # 7 test tube.

Calculation or Transformation

All Parts: Students must complete all Parts of Soil Testing with accurate measuring, mixing and analysis of colorimeter test cards. Conversions of raw data must be converted into Percentages for Soil Typing and another calculating method must be proposed in Test 7.

Application/Analysis Part 8 Percolation Questions A, B, C. Students must draw a conclusion concerning both percolation and retention capability after completing the section. A description and proposed explanation for any color change in any or all of the test tube filtrate is required.

Assumptions Test # 4 Potassium Questions C/D. Students must describe the procedure to improve soil Potassium content and identify any plant samples that would be used because of their high K content.

Communication Part 8 Percolation Question D. Students must propose both a positive and negative impact on plants in a high water retention scenario and support their stance.

Relevance, Accuracy, and Integration of Visual Elements

All Parts: The completion of all 8 tests and the required worksheets implies accuracy of procedural steps and interpretation of colorimeter charts as well as drawing the test tube horizons and cross-triangulating the USDA triangle

GENERAL DIRECTIONS FOR GROUP SOIL TESTING PROJECT

Table members will complete all 8 tests on soil provided by 1 table member. Share the accumulated data with team mates. Each student will then independently complete their own 8 pages of Test Interpretations. They

will analyze the data and respond to specific questions pertinent to each test. Students will also draw a test tube content and cross-triangulate the soil triangle diagram. Each participant within the team will also evaluate their personal participation in the project. The final report grade will be a portion of the 2nd lab test grade (max value: 10 points).

PREPARATION:

Exchange phone, e-mail, contact information with each member of the team. Determine/designate the roles/testing/data collecting of each member of the team. 1 lab period will be identified as the testing day. All 8 tests (see direction sheets Pages 4-5) will

be completed on the specific soil sample. One of the members will be the supplier of the soil sample.

o 1 large gallon “zip-loc” bago Collect soil and dry thoroughlyo Remove any large debris material (sticks, rocks, leaves, etc.)

Each team member is responsible for completing his/her assigned duties and submitting theirown paperwork on the BlackBoard site.

FINAL REPORT

The report form will be available on BlackBoard prior to the testing time frame. Keep raw data of each test result until the team/group completes all 8 tests. Complete the individual test question by referencing outside sources (text, internet, laboratory

book sources, etc.) Utilize correct paragraph structure, proper grammar and punctuation. Attach the cover page indicating team members and assignments. The team “captain” should compile all results into a finished product and submit it to the

instructor for grading. Completion date will be Week # 10; in time to be added to Lab Test # 2. EACH student should complete the personal evaluation questionnaire + submit it on

BlackBoard; answering all 5 questions with a clear explanation for each. Failure to submit thisform will result in a subtraction/penalty of 1 point for each question not answered.

The scoring will be:o Each test (8) @ 1 pt each = 8o 1 completed soil triangle = 1o Project submitted on time = 1

10

TOTAL POSSIBLE POINTS = 10 – any points for non-submission or partial submission of personal evaluation form.
