When we update our lab books, we review all the experiments. Occasionally, we revise experiments to fix errors or remove equipment that can present an unnecessary hazard to students.

In 2017, when we released the 4th editions of some of our lab books to support Graphical Analysis app, we made adjustments to some experiments.
4th Edition Books:

  • Middle School Science with Vernier
  • Physical Science with Vernier

Changes in 4th Editions
Middle School Science with Vernier

Title
(original experiment)		 Title
