This teaching idea has been around for a while, and you can find ready-made instructions and rubrics online. If you'd like to present the project digitally, try this unit by Mariana Garcia. Or, if you'd rather have hard copies to distribute to your class, take a look at this pdf. I also found several similar files created in editable versions. Simply search the term "organelle trail," and you'll find lots of possibilities!
My favorite website for organelle research is Cells Alive! Their interactive cell models allow students to explore organelles, their names and functions, and where they are found.
