I don’t know the specifics of the lab but for a lab report you can find really good templates online. Start with an introduction that includes the question that the lab is trying to answer and include your hypothesis, your independent and dependent variables. Sometimes there may be a paragraph for any background information that was given previously but thats not always needed. Next paragraph have the material needed for the lab even if the lab is virtual and the procedures/ any safety guidelines that need to be included. Next paragraph have the data and any charts or graphs that were in the lab as well as your analysis of them. Say if your hypothesis was proven correct by the lab or not. Then have a concluding paragraph that restates the question that needed to be answered in the beginning, with the answer. Sometimes with the conclusion they may want a real world application for the results but again not necessarily. I hope this can help you. Good Luck!
