What I Do When It’s Time to Do a Lab: A Practical Guide for Students
Let’s face it—walking into a lab session can feel equal parts exciting and overwhelming. Whether you’re dissecting a frog, mixing chemicals, or coding a simulation, labs are where theory meets reality. But how do you make the most of these hands-on opportunities? Over the years, I’ve developed a routine that helps me stay organized, focused, and—most importantly—calm when it’s time to do a lab. Let me walk you through my process.

Pre-Lab Preparation: The Foundation of Success
Labs aren’t something you wing. Walking in unprepared is like showing up to a soccer match without cleats: you’ll spend more time scrambling than scoring. Here’s how I get ready:
1. Read the Lab Manual—Yes, Really
Skimming the instructions five minutes before class isn’t enough. I block out 30–60 minutes the night before to read the manual thoroughly. I highlight key steps, jot down questions, and note any unfamiliar terms. For example, if the lab involves titration, I’ll review what a burette does or how to calculate molarity. This prevents me from freezing mid-experiment because I forgot what “meniscus” means.
2. Gather Materials in Advance
Imagine arriving at the lab only to realize you left your safety goggles in your dorm. To avoid this, I create a checklist of everything I need: lab coat, gloves, notebooks, calculators, and even a backup pen (because ink always runs out at the worst time). If the lab requires specialized software, I install it beforehand and test it to avoid tech glitches.
3. Plan Your Time
Labs often have strict time limits. I break the experiment into phases: setup, execution, data collection, and cleanup. For a 2-hour lab, I might allocate 15 minutes for setup, 90 minutes for the main tasks, and 15 minutes to wrap up. This keeps me from rushing critical steps or leaving a mess for the next group.

During the Lab: Focus and Flexibility
Once I’m in the lab, it’s all about balancing precision with adaptability. Here’s my playbook:
1. Safety First, Always
No experiment is worth a trip to the ER. I double-check safety protocols: Are my goggles snug? Is my workstation clear of clutter? If I’m handling volatile chemicals, I confirm the location of eyewash stations and fire extinguishers. I also remind my lab partners to follow suit—safety is a team effort.
2. Document Everything
Labs are as much about process as results. I use a dedicated notebook to record every detail: measurements, observations, even mistakes. For instance, if a solution turns cloudy unexpectedly, I note the temperature, mixing speed, or possible contaminants. This habit pays off when writing reports, as professors love seeing thorough documentation.
3. Embrace the “Oops” Moments
Last semester, I accidentally added too much sodium hydroxide to a solution. Instead of panicking, I documented the error, restarted the step, and later analyzed why it happened. Mistakes are inevitable, but they’re also learning opportunities. The key is to stay calm, troubleshoot, and ask for help if needed.
4. Collaborate (But Don’t Copy)
Working in groups? I make sure everyone has a role. One person might handle measurements, another operates equipment, and a third records data. However, I avoid relying too much on others’ work. Even if my partner calculates the data, I recheck the math to understand the process.

Post-Lab: Turning Data into Insights
Leaving the lab doesn’t mean the work is done. Here’s how I wrap things up effectively:
1. Clean Up Thoroughly
I’ve seen students lose points for leaving dirty beakers or unplugged equipment. I follow the lab’s cleanup checklist and wipe down surfaces, dispose of waste properly, and return tools to their designated spots. It’s basic respect for the space and the next group using it.
2. Analyze Results Immediately
Data feels fresh right after the lab. I spend 20–30 minutes reviewing my notes, graphing results, or running quick calculations. If something seems off—like a pH reading that doesn’t match predictions—I flag it and brainstorm possible reasons. This saves time later when writing the formal report.
3. Start the Report Early
Procrastination is the enemy of good lab reports. The same day as the lab, I draft the introduction and methods sections while the procedure is still fresh. A week before the deadline, I tackle data analysis and conclusions. This spaced-out approach reduces stress and improves the quality of my work.
4. Reflect on What Worked (and What Didn’t)
After submitting the report, I ask myself: Did my preparation pay off? Were there steps I could’ve streamlined? For example, I once wasted time recalibrating a microscope because I skipped the pre-lab tutorial. Now I prioritize watching demo videos in advance.

Why This Routine Matters
Developing a structured approach to labs isn’t just about getting good grades—it’s about building skills that translate beyond the classroom. Attention to detail, time management, and adaptability are valuable in careers like research, healthcare, or engineering. Plus, labs are a rare chance to “learn by doing,” which solidifies concepts you’ve studied in lectures.
Even if your current routine feels chaotic, small tweaks can make a difference. Start by reading the manual thoroughly once, then gradually add other steps like pre-lab checklists or post-lab reflections. Over time, these habits become second nature.

Labs are where science comes alive. By preparing thoughtfully, staying present during experiments, and reflecting afterward, you’ll not only survive lab sessions—you’ll thrive in them. So next time you slip on that lab coat, remember: success isn’t about being perfect. It’s about being prepared, curious, and ready to learn from every pipette drop or coding error along the way.
