NSCI 120 Natural Sciences Laboratory is a 1-credit course at the University of Maryland Global Campus (UMGC) that fulfills the laboratory science requirement. The prerequisite is MATH 105, STAT 200 or a higher MATH or STAT course.
The catalog describes a study of the basic principles of science investigation and observation. Students use experimental design to address questions about physical, chemical, geological and ecological phenomena, so the skill set is broader than a single-discipline lab.

What NSCI 120 Covers
| Area | In plain language |
|---|---|
| Investigation and observation | Looking carefully and recording what you see |
| Experimental design | Planning a fair test for a question |
| Physical, chemical, geological and ecological phenomena | Questions drawn from several branches of natural science |
| Measurements and data collection | Using tools and recording values accurately |
| Quantitative reasoning | Using numbers to support or reject an idea |
Key Concepts Explained
Observation Versus Inference
An observation is what you directly record, such as "the water in sample B was cloudy". An inference is what you conclude from it, such as "sample B contains more suspended particles". Keep the two separate in your notes and reports.
Illustration (invented): Observation: the plant under shade has fewer leaves after two weeks. Inference: lower light may reduce growth. Check: were water, soil and temperature the same for both plants? If not, the inference is weak.
Designing a Fair Test
State your question, then identify one variable to change and the ones to keep constant. Repeat trials where you can so that one odd result does not mislead you.
Presenting Data
Use tables for raw values and graphs for patterns. Add units, titles and a sentence describing what the reader should notice.
Typical Assignments and How to Approach Them
The catalog lists activities but not assignment titles. This table shows common deliverables for an introductory natural science lab.
| Type | What it tests | How to approach |
|---|---|---|
| Observation log | Careful recording | Write dated, specific entries with units |
| Experiment report | Design and interpretation | State question, method, results and a data-based conclusion |
| Quantitative exercises | Number reasoning | Show the working and check the units and reasonableness |
| Reflection or discussion | Scientific thinking | Point to specific data in your answer |
Designing and Reporting a Simple Investigation
NSCI 120 asks you to apply experimental design to questions about physical, chemical, geological and ecological phenomena. A reusable template makes any investigation easier to plan and write.
| Element | What to write |
|---|---|
| Question | One clear question you can test or observe |
| Prediction | What you expect and why |
| Variables | What you change, what you measure and what you keep constant |
| Method | Steps another person could repeat, with tools and units |
| Data | A neat table of raw values, with repeats where possible |
| Analysis | Averages, simple calculations and a graph if helpful |
| Conclusion | Whether the data support your prediction, limits and next steps |
The catalog lists measurements, data collection and quantitative reasoning exercises, so practice reading instruments carefully and recording the right number of digits. Rounding too early can shift results, so keep full values until the end.
When the activity involves fieldwork or observation of the natural world, describe the location, conditions and date, because these details help readers judge your results.
Describing an Observation Precisely
Observation logs reward specific, measurable language over general impressions.
Weak: "The soil looked wet." Stronger (pattern): "At the 10 cm depth, the soil was dark brown and clumped when squeezed, with visible moisture on the trowel. Surface soil was lighter and crumbled." Details such as depth, color and texture let someone else picture and compare the samples.
Where you can, add a measurement, such as temperature or moisture reading, rather than only describing what you saw.
Working with Different Kinds of Data
The course spans physical, chemical, geological and ecological questions, so your data may change in type from one activity to the next. Counts, lengths, temperatures and descriptions each need a slightly different treatment.
Record numerical data with units and the precision of the instrument. Record descriptive data with consistent categories so you can compare samples. When you graph, choose a bar chart for categories and a line or scatter plot for quantities that change together, and always label axes.
Where Students Get Stuck
- Mixing observation and opinion. Keep raw notes factual.
- No control of variables. Name what stayed constant.
- Rounding too early. Keep full values until the final answer.
- Vague conclusions. Refer to numbers in your data.
Study Tips for NSCI 120
- Read each activity before starting so you know which data to capture.
- Use a consistent table format for every activity.
- Photograph or sketch set-ups if allowed, so the method section is easy to write.
- Check your calculator mode and units before every calculation.
- Use the general structure in our how to write a lab report guide, then follow your instructor's template.
