Hi ScienceRocks03 - Plagiarism is something with which we, too, are always concerned. No amount of plagiarism is okay, and you are right that explaining to students what plagiarism is -- and what it looks like when it's very easy to pull up search materials that can be copied and pasted in place without attribution -- is a crucial step. We have resources and samples on the Science Buddies site for writing bibliographies. We also offer suggestions for helping to cover plagiarism here: http://www.sciencebuddies.org/science-f ... plagiarism
Many teachers spot-check student titles or key phrases from reports in a search engine to help ensure original work.
One of the benefits of having students work with Science Buddies Project Ideas is that our projects do not provide the "answers" for students. In order to complete the project, answer the question, and prove or disprove a hypothesis (that the student has formulated), the Experimental Procedure needs to be actively followed. So the student has to "do" the experiment to complete the assignment. Teachers who have classes use Science Buddies Project Ideas are also able to quickly reference the Project Ideas and look through the introductory and background materials to ensure student reports are original.
