If you are looking for a project to help you assess your students on Acids and Bases, you have found THE project! Your students will not only actively perform their own research using technology, but are also able to investigate in a very hands-on way! They will enjoy the freedom that this project gives them while at the same time challenging them to use every bit of knowledge that you have taught them in this unit! I always save this project for the colder weather when I know they are able to measure the acidity level in the rain. If you have any questions, please feel free to reach out to me!
