Both of these Vernier lab manuals are suitable for high school introductory physics courses. They both include elementary experiments on the topics of motion, force, momentum, energy, electricity, magnetism, and waves. However, the structure and pedagogy of these two lab manuals is very different.

Physics with Vernier (PWV) is an excellent choice for the instructor and student with little experience using Vernier software and probeware. Clear step-by-step instructions are given for each experiment, and the electronic resources provide versions of the instructions for use with Logger Pro, LabQuest, and Graphical Analysis software. Instructor notes provide complete sample data sets and sample graphs.

Physics Explorations and Projects (PEP) is the appropriate choice for instructors using guided inquiry and students who have had some experience with probeware and analysis software. Rather than providing step-by-step instructions, students are directed to create their own procedure. Therefore, the instructions are general enough that the activities can be completed  with any appropriate software. The instructor notes are extensive and give advice on resources and pedagogy as well as lab performance tips. 

A few additional distinctions:

• Physics Explorations and Projects was specifically written to align with NGSS standards, and thus there is a focus on energy. 
• Physics Explorations and Projects includes several projects and challenges that do not necessarily require Vernier products, such as an egg protection challenge and a Rube Goldberg machine.
• Some activities in Physics Explorations and Projects suggest using Pivot Interactives, a subscription software available through Vernier, or video analysis software, such as Logger Pro or Vernier Video Analysis.
• All activities in Physics with Vernier can be completed using Vernier software: Logger Pro, LabQuest, or Graphical Analysis.

A formatting note: In Physics with Vernier, student instructions are followed by instructor notes throughout the book. In Physics Explorations and Projects, instructor notes precede student instructions. In both cases, the lab will run more smoothly when the instructor reads all the notes carefully several days before performing the activity in class.
