First of all, I want to say that people are not born to give academic reports. Just like other knowledge, how to make an academic report also needs to be learned. You can find some good templates to learn online. Remember, it's not plagiarism, it's just letting you learn from others' inspiration. After reading more, you can start to try to make your own academic report.
The most important thing about an academic report is its logic. You should let the people who listen to your report know your overall structure and your central idea at once through this PPT, so the logical structure of the academic report must be good, the content should not be too complicated, and it should be as concise and clear as possible to make people look like a good academic report.
Finally, after ensuring the logic and neatness, some beautification can be carried out. Although beautification is not necessary, it will definitely make your PPT go up a storey still higher and look more perfect as a whole.
