Make sure that you are prepared before you start! Being prepared means that you know what materials (including tools and safety equipment) you need. You also need to know the steps that you will do to conduct your experiment. Make sure to write them down in order so that it is easy to follow!
What will you use for your experiment? What are the steps? Both are important questions to answer BEFORE you start your experiment. Be as detailed as you can when you are writing your materials list and your procedure!Â
