From Entertainment To Education: The show is used for a variety of subjects. However We The People is notably used to help students remember the Preamble to the U.S. Constitution.
Meaningful Release Date: "Fireworks" was originally aired on July 3, 1976, i.e. the day before the bicentennial. This makes the lyric "we declared our liberty two hundred years ago" only one day short of being accurate to the day.
Missing Episode: Even discounting the weather short that was removed from syndication for years, there is one Scooter Computer episode that has yet to receive an official home video release. "Introduction" only survived in audio form on the four-CD soundtrack set released in 1996. That is until August 2013, when Darrell Stern (voice of Scooter Computer) found a VHS tape of the lost video and put it up on YouTube. You can view it here.
Technology Marches On: "Telegraph Line" explains how the nervous system works, using telegraph lines as an analogy. These days, it would be easier to explain the nervous system to a child than it is to explain telegraph lines, as they haven't been around since the 1990s.
The "Scooter Computer and Mr. Chips" segments suffer this as a whole due to being about computer technology that quickly became outdated. As such, these segments haven't receive the reruns. In fact in the DVD release, they are on the special features disc instead of the main one.
One song was about interest. A viewer in the new tens might be confused at how small the interest rates on Becky Sue's loan is - the song says "For every dollar you borrow you gotta pay the bank a dollar and a dime", suggesting an interest rate of 10%. Banks may actually charge higher interest rates than that in the 20-teens — especially if it's a student loan.
"$7.50 once a week" due to inflation - one amusing bit to a modern viewer would probably be how the narrator talks about spending a lot of money ($2.00) on Chicken Enchilada - only to find that he could have saved $1.50 if he went across the street. In the new tens, $2.00 for a restaurant meal is almost unheard of (unless it's one of those cheap, fast-food places, but even then, it wouldn't cost you just $2.00).
"The Check's In The Mail" has a lot of people using pay phones.
"I Got Six" also has an inflation example. The menu for the downtown restaurant has no item more than $9.00. In the new tens, you would not find an item for less than that amount.
