PSI - Physical Science Investigation -is a series of physical science video lab experiments aligned with the Ohio Science Academic Content Standards for grades 6-8.
In this teacher resource area, for each experiment you will find a lesson plan, additional resources, and two types of video for you to review before conducting a lesson: a professional development video as well as all of the student video segments you will show from the main PSI page in the classroom.
To get started, watch the introductory video on the right or just go ahead and click on one of the tabs above in order to gain access to all the resources herein.
