Course & Plan InformationCourse Rubric/Number / BIOL 1311 (Lecture) + BIOL 1111 (Lab)
Course Title / General Botany
Component Area / Biological Sciences
Outcomes assessed
(per district-wide syllabus) / Communication Skills; Critical Thinking; Teamwork; Empirical/Quantitative
Effective Date / Fall 2015
Summary (for faculty, expository explanation of assignment)
Students working in groups of 3 – 4 will complete 8 different tests on soil samples they provide; ph, nitrogen, phosphorous, potassium, humus content, percolation rates, soil typing + horizon settling. Group members will decide who will be assigned specific tests and then complete the testing during a scheduled laboratory period.
Subsequent meetings of group members will provide time to communicate and share the Q/A results for each test, compute mathematical calculations and fill in the soil triangle for a completed project.
Students will also score an evaluation sheet of the other team members in their group as part of the project.
Each student will submit the completed project (total 8 Pages) on the linked Gen Ed project site on BlackBoard.
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” content item in Blackboard. Faculty electing to use Turnitin may do so, but students will need to submit the document 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 for the course; thus, all assignments should be included as a regular grade in the course. The assignment should not be considered optional, extra-credit, or a bonus activity.

GENERAL DIRECTIONS FOR GROUP SOIL TESTING PROJECT
Ø Each table will work together as a team in completing this soil analysis project.
Ø Each table/team will agree on the assignments for each member (8 tests/8 report sheets).
Ø Each participant within the team will also evaluate the work of each of the other participants.
Ø The final report grade will be a portion of the 2nd lab test grade (value: 10 - 12 points) dependent upon each individual’s evaluation score)
PREPARATION:
Ø Exchange phone, e-mail, contact information with each member of the team.
Ø Determine/designate the roles/testing/data collecting of each member of the team.
Ø 1 lab period will be identified as the testing day. All 8 tests (see testing handout) will be completed on the specific soil sample.
Ø One of the members will be the supplier of the soil sample.
o 1 large gallon “zip-loc” bag
o Collect soil and dry thoroughly
o Remove any large debris material (sticks, rocks, leaves, etc.)
Ø At least 1 follow-up meeting of the team should occur in order to coordinate the exchange of individual data and the production of the final report.
Ø Each team member is responsible for completing his/her assigned duties. The individual evaluation scores will reflect the other team member’s interpretation of your participation/work performance.
FINAL REPORT
Ø The report form will be available on BlackBoard prior to the testing time frame.
Ø Keep raw data of each test result until the team/group completes all 8 tests.
Ø Complete the individual test question by utilizing outside sources (text, internet, laboratory book sources, etc.).
Ø Attach the cover page indicating team members and assignments.
Ø The team “captain” should compile all results into a finished product and submit it to the instructor on behalf of the whole team.
Ø Each individual team member will also collect and submit the SAME ENTIRE report on the designated Gen. Ed. Outcomes BlackBoard site.
Ø Completion date will be Week # 10; in time to be added to Lab Test # 2.
Ø Individual evaluation scores will be submitted (AND remain anonymous) separately in a sealed envelope to the instructor on the day of Lab Test # 2.
Ø The scoring will be:
o Each test (8) @ 1 pt each = 8
o 1 completed soil triangle = 1
o Project submitted on time = 1
10 total
+ avg of eval.form 0 – 2 pts
TOTAL POSSIBLE POINTS = 10 -12 (calculated as a portion of lab test # 2)
