Improvements and problems

•  To improve my investigation, I could have done more trials rather than just three I could have done 5, by doing this it would have made my results more accurate. Also, the amount of salt that I had chosen to do could have been more for example they could have gone up by 40 or 60 grams instead of 20. 
• By doing this, my experiment would have supported my hypothesis and research even more and my results would have been more precise.
• Using a bunsen burner would also benefit the experiment, to have a consistent heat source and by having a constant heat source, you would be able to have the time it takes to boil by using a stop watch. 
• Timing my results would also benefit my experiment, to ensure there will be a change in time for every time I add more salt. From my research the water will take longer to boil at a higher temperature including the solvent which is the salt. 
• If I had some more time I could have extended my experiment further by adding salt to  different types of water  such as distilled water, mineral water, spring water etc or I could have used different brands of salt. 

• The experiment did not come across any problems, the only one little problem occurred while the water was boiling. 
• While I was waiting for the water to boil I had gotten distracted, I had started filling the container with salt for the next trial. I had gotten to the saucepan when it was boiling a lot.
•  I should have watched the saucepan and waited for the water to boil instead of leaving it too long. Other than that little error I was very happy with my experiment and what I had accomplished.
