Lab experiments demand a lot of precision and care, making it easy to make small mistakes. In order to avoid this and ensure you can write a great lab report, here is some advice for when you carry out your next experiment.
All sciences assess your ability to carry out lab experiments. Luckily, you will practise and develop your skills in school, as teachers will make sure you do plenty of practical work. Lab experiments demand a lot of precision and care, making it easy to make small mistakes that can ruin the entire process. In order to avoid this and ensure you can write a great lab report, here is some advice for when you carry out your next experiment.
Follow the plan
The first thing you have to think about is planning your experiment. Write down the equipment you need, your hypothesis, your entire process (the steps you will follow) and how you will record your data. The more detailed your equipment list and process is, the less likely you are to make mistakes or forget something crucial. Once you make your outline, make sure you stick to it. If you don’t follow you plan, you might end up making silly mistakes.
Dependent and independent variables
Students tend to confuse their variables, which is a killer. Your dependent variable is what you measure/record, while your independent variable is what you change. So, if you are doing an experiment on the effect of pH levels on lactase activity, your independent variable would be the pH level (since you are changing it) and your dependent variable would be lactase activity (as you are measuring it). Also, remember to only have one dependent variable and one independent variable. All other variables should be the same throughout the experiment. Otherwise, you are doing something wrong.
