Science Project Ideas

Remember that these project ideas and outlines are meant to help you complete your own science project. But it is DISHONEST and UNETHICAL to copy someone else's project work samples and submit them as if they were your own. That's called plagiarism and it's a fast way to get a failing grade. It's okay to do the same project as someone else, or review what others have done so you can make your project better, but DO NOT COPY and pretend it's your project. Someone is sure to spot the plagiarism!!
