That isn't a lot, so you have to choose what you say carefully. In written form you can edit to make sure important points are there while lesser items or redundancies are eliminated. Next, decide which material you want to present on slides or overheads. Making overheads is easy since almost any xerox machine will prepare them from a printed or hand-drawn original. Your research supervisor may have slides or diagrams useful for your introductory section.
Results are usually well suited for presentation graphically.
That way you don't need to read out numbers, but rather point to the important data while showing, not always with comment, less important data and control experiments. The last stage is to rehearse your talk and get comments. Then give it at your group's research meeting, and ask your audience suggestions. The honors program requires you to have one special rehearsal before you present the talk in one of the sessions of BioSci 299. That rehearsal is before a group of at least 3 of your colleagues in the program, each of whom will prepare brief written suggestions to help you improve the presentation.
