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 Middle School Science with Vernier and Physical Science with Vernier, we made adjustments to some experiments resulting in necessary changes to the experiment files in Logger Pro and Logger Lite:

Updates for Middle School Science with Vernier

Original experiment file Current (4th ed) experiment file Change
09 A Good Sock no change Updated duration to 15 min.
11 Solar Homes no change Updated duration to 30 min.
27 Magnetic Field no change Changed axis label from Distance to Position.
33 (all) Graphing Your Motion no change Updated so “match lines” do not include quadratic segments and will fit in a 2 m space.
34 Velocity 34 Speeding Up Updated title, experiment file, and student pages for improved alignment.

Updates for Physical Science with Vernier

Original experiment file Current (4th ed) experiment file Change
03 Freeze Melt Water no change Updated data-collection rate to 100 samples/min.
12 Insulated Bottle no change Updated graph title.
13 A Good Sock no change Updated duration to 15 min.
15 Solar Homes no change Updated duration to 30 min.
17 Saltwater no change Changed column name to Volume and units to drops.
24 Polaroid Filters 24 Polarizing Light Updated title to generic term.
27b Magnetic Field no change Changed axis label from Distance to Position.
29b Acid Rain no change Changed column name to Volume and units to drops.
34 Lead Storage Batteries 34 Simple Circuits Replaced original experiment so students are not using hazardous materials.
35 (all) Graphing Your Motion no change Updated so “match lines” do not include quadratic segments and will fit in a 2 m space.
36 Velocity 36 Speeding Up Updated title, experiment file, and student pages for improved alignment.
38 Momentum 38 Crash Lesson Updated title, experiment file, and student pages for improved alignment.
