My grandchildren began High School (9th Grade) in St. Charles, Missouri this month.
They are using the 2009 Edition of the textbook "Physical Science Concepts in Action," published by Prentice Hall. They access this text online, and their assignments are announced online, by entering their respective user names and passwords. I have examined the section on Measurements and am pleased to observe that this section uses SI exclusively.

"Physical Science Concepts in Action" is a *winner.* At least some students in the upcoming generation will be well educated in SI Eugene Mechtly
