A report is VERY different from an essay, and so it’s very important that you follow your teachers instructions.
Reports convey specific information about a topic, often concluding with specific recommendations or knowledge summaries. They are usually focused on a specific topic, event or results.
In general a report doesn’t have a set structure, but will include:
A title page AND a table of contents each on their own page
Illustrations / diagrams / bullet points / pictures that ENHANCE and EXPLAIN the content
Sections / Topics, with headings to help organize the report
Conclusion – draw recommendations/conclusions from the information presented in the report. the purpose is to be straightforward (not flowery) and grounded in information that is IN your report.
Proper bibliiographical techniques (in the appropiate format), captions for any images / tables / diagrams
A report template can be found here.
Note: Image/table/figure captions are tricky to do in google docs. There is a glitchy add-on you can try, or make each into a google drawing and add the caption in the drawing. You can see this in the sample.
