Molecules of Life Test
Background and Use
This resource is the test I use at the end of the 10th grade Biology unit on molecules of life. The main topics are macromolecules, pH, and water. It consists of 40 multiple choice questions, mainly knowlege/vocabulary based. Few if any application-level questions. Feel free to change or add to this resource however you like. I use the Zipgrade app on my phone to grade bubble sheets you can print from their website. The app is $6.99 per year but saves so many hours of hand grading it is totally worth it.
I have included the test here within this resource builder and also attached it as a 2-page Word document.
