You should start your report with an introduction. This will be a short paragraph, where you will present the laboratory where the class was held, the time and date. Then you will give a brief presentation of what was observed during that class.
In a second paragraph, you will start by explaining better, all the elements of the class, what was discussed and what equipment was used. You should also show all the activities done in the laboratory in the most detailed way possible. This paragraph can be divided into more than one paragraph, if you have a lot of information to tell.
Finally, you should end the report with a conclusion, showing what you have learned from this experience.
