📝 Course Syllabus: Undergrad Astrobotany & Space Biology¶
Course Overview¶
- Course Code: ASTROBIO 401
- Course Title: Advanced Astrobotany & Space Biology Research
- Credits: 4.0
- Prerequisites: General Biology, Introductory Genetics, or permission of the instructor.
- Format: Combined Lecture & Laboratory (approx. 2 hours lecture, 4 hours lab per week)
🔬 Course Description¶
This course offers a hands-on, research-intensive exploration of plant adaptation to spaceflight and simulated microgravity conditions. Students will progress through the Classroom and Extension tracks of the AstroBotany Investigation Resource (AIR). They will learn to build scientific photography systems, run automated phenotypic analysis pipelines, execute simulated-microgravity assays on clinostats/RPMs, simulate plant development and hormone transport computationally, and analyze spaceflight transcriptomics (RNA-seq).
🎯 Learning Outcomes¶
Upon successful completion of this course, students will be able to:
- Design and calibrate scientific plant-imaging platforms using specialized standards.
- Quantify plant phenotypic growth and root system architecture using automated software (PlantCV, Fiji/ImageJ).
- Analyze and interpret gravitropic reorientation kinetics under 1G and simulated microgravity (RPM).
- Develop and simulate multicellular plant models of hormone transport and root hydraulics.
- Analyze transcriptomic networks (RNA-seq) of plants grown in actual spaceflight environments.
- Communicate advanced scientific findings via a peer-reviewed style manuscript and an oral presentation.
📊 Grading Policy & Breakdown¶
Your grade in this course is based on continuous evaluation of laboratory participation, weekly deliverables, computational modeling projects, a research proposal, a final presentation, and a scientific manuscript.
| Assessment Component | Weight (%) | Description |
|---|---|---|
| Weekly Laboratory Journal & Deliverables | 25% | Documentation of weekly lab setups, phenotypic measurements, and calibration checkmarks. |
| Midterm Project Proposal | 15% | A formal 3-page research proposal outlining an independent extension study. |
| Computational Modeling Reports | 15% | Reports on simulated auxin transport, root hydraulics, and gene database mining. |
| Independent Project Presentation | 15% | A group presentation summarizing findings from independent experiments. |
| Final Laboratory Report (Manuscript) | 30% | A formal, peer-reviewed style manuscript detailing the outcomes of the 12-week study. |
Grading Scale¶
- A: 93.0% – 100% | A-: 90.0% – 92.9%
- B+: 87.0% – 89.9% | B: 83.0% – 86.9% | B-: 80.0% – 82.9%
- C+: 77.0% – 79.9% | C: 73.0% – 76.9% | C-: 80.0% – 72.9%
- D: 60.0% – 69.9%
- F: Below 60.0%
🏅 Grading Rubrics¶
1. Laboratory Journal & Deliverables Rubric (Graded Weekly)¶
| Criteria | Excellent (4-5 pts) | Satisfactory (2-3 pts) | Needs Improvement (0-1 pts) |
|---|---|---|---|
| Completeness | All weekly setup details, calibration checks, and phenotypic numbers are logged. | Most details are logged; some minor omissions or uncalibrated photos. | Missing substantial entries; data is incomplete or undocumented. |
| Scientific Accuracy | Proper botanical nomenclature, appropriate units, and controls are documented. | Minor scientific/computational errors; units are occasionally missing. | Incorrect scientific terms; poor methodology documentation. |
| Data Visualization | High-quality, clear graphs/plots are inserted with properly labeled axes. | Graphs are present but lack clear legends or axis labels. | No graphs or raw figures are present in the entries. |
2. Final Laboratory Manuscript Rubric (30% of course grade)¶
- Abstract & Introduction (20%): Clearly introduces space-biology significance, tropism models, and states a testable hypothesis.
- Materials & Methods (20%): Thoroughly documents photography setups, clinostat/RPM parameters, software settings, and plant growth metrics to ensure full reproducibility (FAIR standards).
- Results & Figures (25%): Incorporates beautiful graphs, PlantCV segmentations, statistical analysis (t-test or ANOVA with p-values), and modeling simulation outputs.
- Discussion & References (25%): Critically interprets results in the context of peer-reviewed space literature and models. Integrates NASA transcriptomic correlations.
- Clarity & Formatting (10%): Professional tone, logical transitions, standard scientific layout, and formatted citations.
🚪 Course Policies¶
- Academic Integrity: All students are expected to follow the university's academic honesty policy. Collaboration on laboratory experiments is highly encouraged, but all written proposals, computational modeling reports, and final manuscripts must be written individually.
- Late Work: Late assignments will face a 10% deduction per day unless prior permission has been granted under exceptional circumstances.
- Laboratory Safety: Safety is paramount. Lab coats, closed-toe shoes, and safety goggles are required during any chemical preparations (such as agar medium preparation and sterilization workflows). No food or drink is permitted in the laboratory space.
