The purpose of this research report is for students (grades 7-9) to get a further understanding in how mutations on various genes cause different types of diseases. The project should be given to students once they have background knowledge on genetics and heredity so near the end of the unit would be best. In a class of 24 for example, place 24 numbers in a container and those numbers are the order for the picking of the genetic diseases. Don't allow more that two of the same genetic disease per class period because later on, students will be giving powerpoint presentations and you don't want the presentations to become repetitive. Allow students to pick the disease they want to research. This helps to bring about ownership and maintains interest. Give students two class periods (45 min.) for research. Tell students they are not allowed to work on the powerpoint, only the research. Then on the third day, create the powerpoints together as a class. Tell students, "You'll have three minutes to work on your first slide which incudes your name, hour, and type of disease. After three minutes, we'll be moving onto slide 2. Your three minutes starts now." After 7 years of teaching this lesson in various formats, I've found this to be the most effective. If you allow students to work on their powerpoints at any point, chances are they'll spend too much time on sound, font, background, and slide transitions. I want students to get the content down and to not focus in on the "fluff" so to speak. Only 3-5 minutes is given per slide. Then, once the powerpoints have been completed, we present them in class. If you'd like to keep your audience focused, have them take notes in their notebook.
