This quiz is specifically written to address NGSS MS-PS1-5. It includes simple diagrams to analyze and the questions mimic how state standardized tests ask about this topic.

Two similar versions are provided. The versions look exactly alike and have the same questions, but a different order of the correct answers. So, wandering eyes will see a quiz that looks like their own but will get the answer wrong if they copy a neighbors paper.
