Do you need- or want to have students participate in a science fair? This is an entire 31 page science fair workbook. It has been designed and tweaked over a 10 year period to be extremely practical and both student- and teacher friendly. I use this for my 7th and 8th grade students, but this could easily be used by anyone in grades 6 through high school.I have intentionally not saved this as a PDF so you can customize it as best fits your situation.
I print a copy of this for each student and they keep it in a binder.In my situation, this project takes about 2/3 of the school year (we generally do one topic a week aside from the collection of data which students have the entire 2nd quarter to complete.) However, you could make this go much faster or slower depending on the frequency of assignments.
This project contains everything you will need from research, parts of the scientific method, and explanations and pictures of how the note card, binder and display board should look. I've even included information on how to present your project in class and the rubrics I use for grading.
I believe you will not find a more thorough or user friendly science fair project.
If you are interested, I can also upload a topic-selection packet I give my students to complete over the summer as well as a few other related items. (E-mail me if you have specific needs as I may have what you are looking for.)
