Writing Conclusions
Navigate the knowledge tree: 🌿 Skills ➡ Life Processes
The CONCLUSION is linked back to the aim or hypothesis and should be written as a short statement to explain simply what you have discovered.
For example: Increasing the force used to push the trolley increased the speed of the trolley or as the force on the trolley increased, the speed of the trolley increased.
If possible, you write a general statement or GENERALISATION - one that seems true in most cases.
For example, in the report to the right, the student wrote: The heavier the truck is, the longer it takes to stop.Â
You will not always be able to make a generalisation like this. And in some cases, it may not be possible to make a conclusion at all. If the experiment gave strange results, then it may be necessary to say something like this: No valid conclusion can be made using the results obtained in this investigation.Â
Remember that observation investigations use our sense and we often see changes over time. For example, we can observe a candle before lighting, when we light it, while it is burning and after we blow it out.Â
We would describe what we see, smell, hear and how the candle changes over time. What we would describe would be the conclusion. A conclusion is the part of an investigation that summarises the results and what we found out. Â
