How to Write a Band 6 Biology Research Report: A Step-by-Step Guide

Let me guess — you’ve just finished your biology experiment, and now the real challenge begins: writing up a polished, mark-worthy Biology report 🫣

I’ve been there. And not just once — I’ve helped hundreds of students write reports that went from chaotic data dumps to crystal-clear, top-band submissions 💯

So if you’re staring at a blank page wondering where to begin, I’ve got you.

In this guide, I’ll walk you through the exact process on how to write a research report for HSC Biology that I use with my students.

From structuring your content to presenting your findings confidently, you’ll have all the tips and tricks to nail it ✅

Let’s go!

Why Writing a Strong Biology Report Matters

Step 1: Title

Step 2: Author/s

Step 3: Writing a Hypothesis

Step 4: Introduction

Step 5: Methodology and Materials

Step 6: Results

Step 7: Discussion

Step 8: References

Step 9: Formatting and Referencing

Why Writing a Strong Biology Report Matters (More than You Think) 

It’s not just about ticking boxes ✅

A strong biology report shows your ability to:

• Think like a scientist
• Communicate like a professional
• And most importantly — back up your ideas with evidence.

And those are skills that go way beyond your HSC.

But writing it can feel like the wild west without a clear roadmap.

So let me share the structure that saved me — and my students — from last-minute meltdowns. 💥

Don’t wait until it’s too late to master your Biology Reports! Let our experienced HSC Biology Tutors support your studies at one of our campuses, at your home or online.

Step 1: Understanding the Research Question 

First things first: what are you actually investigating? Your research question needs to be clear, testable and actually relevant to biology.

In this article, the experiment I conducted was about how salinity affects lettuce seed germination, but you can do your report on anything that takes your fancy!

🌱 Example: How does increasing salinity affect the germination rate of Lactuca sativa (aka lettuce) seeds?

Translation: Can lettuce handle salty vibes, or does it bail?

Step 2: Conducting Background Research 

Time to get nerdy – do your research! 🤓

You need to explain why this question matters — and that starts with looking to scientific sources to explain what’s already known.

Here, what’s the science behind why seeds might refuse to grow in salty soil? That’s what your intro to the biology report is about to uncover. 

🔍 Example: Looking up how osmosis works in plants can help explain why salt might mess with seed germination.

💡 Pro Tip: Use reputable sources like textbooks, academic journals, and government science sites. Stay away from random Reddit threads and Tumblr posts from 2012.

Step 3: Writing a Hypothesis

Now it’s time to predict what will happen — an educated prediction. 

🔬 Example Hypothesis: If the salinity level in the soil increases, then the germination rate of Lactuca sativa seeds will decrease because higher salt concentrations disrupt water uptake.

Translation: Too much salt = thirsty seeds that can’t grow.

Step 4: Outlining Variables 

Every good experiment has variables! Here’s what you need:

• Independent Variable: Salinity levels (0%, 1%, 2%, 3%) 🌊
• Dependent Variable: Germination rate (%) 🌱
• Controlled Variables: Soil type, seed type, temperature, water volume (Keep these the same so your results aren’t a mess!

🎯 You’ll come back to these in your discussion when explaining why your results turned out the way they did.

Step 5: Writing the Method 

Time to explain the steps you followed to do what you actually did 👩‍🔬

Your method should be so clear that another student could copy your experiment exactly (but, you know, not in a cheating way 😅)

📝 Example Steps:

1. Label petri dishes for each salinity level.
2. Place 10 Lactuca sativa seeds in each.
3. Add equal amounts of salty water.
4. Keep temperature/light constant.
5. Count germinated seeds after 5 days.

🎨 Include a diagram or flowchart to visualise your setup. (Bonus marks and fewer questions from your teacher!)

Step 6: Results

This is where your experiment starts to come alive.

When writing up the results in your Biology Report, use:

• Tables for clarity
• Graphs (e.g. bar or line graphs) for visual impact
• Statistics if required (mean, mode, percentage change)

📊 Example Table: 📊 Example Bar Graph:

Step 7: Discussion

Now comes the brainy part —  where you analyse your results 🧠

What trends do you see? What might have affected your results?

🔎 Example Analysis:

• The results support the hypothesis — higher salt = lower germination.
• Link it back —This makes sense because osmosis affects water uptake in plants.
  

• Mention potential errors — Maybe some seeds were duds (seed quality) or uneven watering occurred across the dishes

🎯 Highlight at least one thing you’d change if you repeated the experiment.

Step 8: Conclusion

Time to wrap it all up by summarising what you found and suggesting improvements.

📝 Example Conclusion: The experiment confirmed that higher salinity negatively affects lettuce seed germination. Future research could test different plant species or see if seeds can adapt over time.

🎯 What questions are still unanswered? Use this to suggest further research.

Step 9: Formatting and Referencing (Like a Pro)

Your report should follow a structured format:

• Title (Make it clear and scientific.)
• Abstract (A short summary—think of it as the TL;DR version.)
• Introduction (What are you researching and why?)
• Method (Step-by-step process.)
• Results (Data in tables/graphs.)
• Discussion (What do the results mean?)
• Conclusion (Final summary.)
• References (Use APA or Harvard—don’t just wing it!)
  

In the references section, cite any and all literature you may have mentioned or used in your report. Referencing styles may vary from school to school, so make sure you check your marking criteria!

For example:

Note: These sample references utilise the University of Sydney’s Harvard style referencing.
