I remember a production company named Screen Gems from many years ago. These motion pictures are truly Gems! Thank you for the conservation and sharing of these treasures.
According to a catalog, this film is made in 1979, and is a part of the three-film "Elementary Physical Science" series. The other two films are "Simple Machines: Using Mechanical Advantage" and "Oxygen--An Introduction to Chemistry." The last two films are listed in several catalogs with a 1978 date.
It was nice to see Fischer-Technik featured, rather than LEGO's! They were definitely the better platform for engineering models, facing no competition that I'm aware of, prior to the introduction of LEGO Technic.
I didn’t catch that contraption was made from FischerTechnik until I read this post. I have quite a large collection of these sets. I made a device that figures the combination of Master locks. You can see it on my channel.
I noticed that too. Here in Australia circa 1975/1976 a schoolfriend of mine had the Basic level set, I thought it was fantastic but it was as expensive as you wouldn't believe, and really needed the addition of the next set to build anything super interesting. I think Fischer-Technik suffered a huge hit from LEGO's me-too offering of LEGO Technic (which I love very much).
I noticed that too! Now I want to get my FischerTechnik collection from the garage. I didn't have much of it when I was the age of Lisa, the girl in the film, but a few years ago I bought a bunch of boxes off eBay. It's pretty rare in the USA, unfortunately, but I got some nice sets such as a complete set of Hobby boxes. And a couple of computer interfaces.
I thought it was funny that they showed this. I really wouldn't recommend doing that. I've had a used 9-volt battery exploding that apparently got shorted because of some coins on my desk. It went off like a firecracker!
I have a big deep nostalgia of an era I didn't live.... thanks Fran! Imagine this in a real dedicated moment in a cinema theatre with the genuine warm sound of stereo speakers and one big speaker behind the big projection screen...
Fran - What great finds these old films are! I would appreciate your comments on the films maybe edited in as intros/outros or voice overs to put them in context from a historical or engineering context - like you did on the silent vacuum tube film. You're a great explainer!
I love these. I'm thinking this one was made in the 1960's or early 1970s partly because of the following: 6:18 Mallory became Duracell in 1978 (or so says the first result of my search) so this was probably made in the 70's unless they used an old battery. They did not use an electronic game at 1:14 to show that we can have fun with electricity which they surely would have done in the late 70's and later, unless made by the type of people that always oppose new forms of entertainment. Of course all that does not prove anything, they do not mention computers but this was obviously made after the 40's. Edit: Julia Vixen (in one of the replies below) found a Duracell at 12:05 so my theory of 1960's to early 1970s is wrong.
The US Cent at 8:00 was minted in 1973 or earlier. I can't see the date directly, but the US Mint re-engraved the dies for the Cent in 1974 (for cents minted with that date) and the "Penny" at 8:00 is definitely minted with one of the dies used prior to 1974.
@@chasmosaurus3 I was convinced by Tom's Shirt, as I wore one like it, I'm sure after 1980, but yes, Mallory Batteries were pretty much history "right around, 1980" They were likely old stock, and, they didn't flake out quickly, so a 2/3 years old Cell/Battery was a sure bet. I recognized the Panel Meters as 1980, but it doesn't preclude they might have first hit the shelves in '79. I recognized the kids clothing as well (yeah, you got it, lol) I now agree with 1981 as a more probable year, and 1979, (& these kids are on the cusp of modernity). Yes the older girl doing the experiments, her Hair Style wasn't a thing, until 1981. It's possible, like I mentioned, her and Tom, with his short button collar shirt, to be trend setters. I remember getting my first short and button collar shirt in between 81 and for definitely sure, I had a few different ones in my closet in 1983. The first girls Overalls; I still remember the Adverts. "Get your kids, Osh Kosh, by'Gosh" My Mother, liked the name, (& said it many times, like a tongue twister, so it stuck in my memory) bought us kids each a pair, unless I'm mistaken. I know we each got a pair and for sure one or all of us got that brand. I had a pair in ?1978/79? maybe it was 1980, but not after as is only wore Corduroy or Jeans after that. "Vvt,vvt,vvt,vvt" as you walk around (& I found it was great fun to shuffle across the shag carpet in Corduroy, and touch a sibling, & lol "teach em, you know, about electricity)" Eventually they figured out how to zap me in return.
About five to ten years too late. I was a kid in school in the mid-eighties, and we certainly didn’t dress like that. My oldest sibling’s school photos looked just like these kids.
At 2:15, "There are about 100 different kinds of atoms...." the periodic table of Elements must have been undergoing some flux or revisions at the time!
Great stuff Fran! reminds me so much of the films we used to watch in school. I used to deliver the films in our school, was not until High school that we began to have televisions to view things (makes me feel old haha)
Hey Fran. I was just thinking a week or so ago of how I missed that music you did in your intros. I am happy you brought it back. I was thinking of watching one of your older videos just to hear that music again. Thanks.
I could identify a # of things I remember from 1979. It has to have been recorded in between 1979 & 1980. Things were still Film Recording over Video Tape, for School use as few schools had video players, but ALL, had Film Projectors back then. They would have re used Fonts etc from 5 years earlier, rather than re design Why fix what ain't broke. The second Public School I attended, did have 1 huge B&W Video Tape Machine, but the bulk of the presentations we saw were all on Films.
@@RetroCaptain When I was in grade school it was the era of VCRs (and LaserDisc players), but sometime around 1999 or 2000, they showed us a film, an actual film, that even then had already faded to bubblegum pink.
This looks so 70s to me. I just love watching old documentaries and old TV cuts. What a different world we live in today with cancel culture and political correctness ect. The technology is better now and we can feed more people that ever with GMO products and modern farming methods however I really miss so many things in how we lived back then. Thanks for the video Fran:)
You would be surprised how much the first couple of years of the 80s still look like the 70s. Anyway to me it looks more like very late 70s due to the text's font used
Oh quit whining, mate. The only thing you're required to do today, that was optional in the 1970s, is to treat minorities with the same respect as the rest of the people. If you don't want that, join the 1 or 2% of subscribers that left when Fran posted her coming out story. Admire the movies for what they are - great documents of scientific knowledge, sometimes presented in a quaint way.
Very nice job Fran. I was for years a telecine operator. I've run thousands of 16 and 35mm films. You got it down. Faded color prints are difficult but I think some heavy handed post color correction would help.
Fran pins point the year of the film between 1972 - 1981. By what the crew and the kids are wearing, including the background music, I pinpoint this documentary to be around 1977. I used the "Eight is Enough" series gauging method.
It has to be pre-1978. That is when Mallory Battery was purchased and renamed Duracell. I was going to say early 80s because of the Fischertechnik stuff, but I was surprised to find that they go back to 1966. Also, great archiving work. I've been really enjoying this.
i guess i was the only one thinking "this is what we call a *short* circuit" when she connected the wire directly between the terminals of the battery. 🤣😂
I remember seeing a couple films in school back in the 60’s. One was about mathematics that had Donald Duck showing how to figure the angles to make a shot on a billiard table. Another featured Wally Cox talking about the advantages of diesel power compared to regular gasoline engines.
I am so glad that "The energy of electrons" is not your choice of title, because, although electricity can be the energy carried by moving electrons, there are so many uses of the word electricity that are not so. For instance the charge carriers in cells are charged ions. And as everyone knows the wire does not carry the energy, the electric and magnetics fields around the wire carry the energy, in a direction given by that nice Mr Poynting's vector.
There are multiple opportunities present to improve the color rendering. First, a color "field flattening" operation should help remove the consistent color warp effects on every frame, most noticeable around the edges and horizontally. Reference black and white frames are synthesized that are then used to remove spectral shifts at each pixel, independent of content. Second, there are multiple objects in various frames that should have well-defined spectra: The o'scope phosphor, the heater elements, etc. Manufactured items such as the batteries used may have archival color references. Enough of these, with enough points across the rendered color spectrum, should permit much improved color recovery. Third, rapid motion in this film exhibits color separation, meaning at least one stage of the capture-to-print process was done using field-sequential media. This makes me believe the film itself is a print from a video source created from a color-sequential video camera, a technique used back in the day to directly map video subframes to film layers.
I think you are of my generation. Films like this inspired us to explore physics and technology. At the fundamentals. I fear that may be lost to the current philosophy of Instant Gratification. Just GOOGLE that answer. deep sigh...
Being Not Da Momma helping Da Baby with fuzzy math, I doubt it. I had to really concentrate to understand the questions and never did comprehend the general answers. Should be called murky math.
That demonstration of shorting out a fat battery and adding a scene with the disclaimer that it's at least "a bad idea" to leave it that way... Yeah ok
@@piratetv1 When I got my first power supply to play with, at the age of 8, I one day got the bright idea to run three volts through a chain. Like a foot long. I moved it a little to see if there's any magnetically induced kinetic resistance. And I burned my fingers 😂
I would go with early 70's base upon those beautiful Hewlett Packard oscilloscopes behind Patty at about 7:00 in. I still have a fantastic dual beam HP scope from that era that has the very same face plate design. I have not powered it up in years and I wonder if it still works?
@ 1:07 it shows a Toyota 20R engine, which was made from 1975-1980. Based on that and judging by the battery in that shot and the clothes and hair, probably 1976-1978. Simpler times, but I've already lived through them. Oof!
The styles and looks of the young people in this video remind me of how things were in 1976 and bell bottoms were still a thing during that year .I did not care for the circuit with a wire directly across the battery as that is a recipe for fire or explosion depending on the type of battery shorted. Try doing that with a lead acid cell or Nicad cell,good luck with that.
Right, I was thinking the same thing. I've had a used 9-volt battery exploding on me one day, that was lying around on my desk and apparently got shorted by some coins. It went off like a firecracker! 😱Don't try this at home, kids!😅
Terrific film. I am guessing it had to be made in about 1982 to 1984. They showed a quartz clock movement in the film. These were made after 1980 if I recall correctly.
Bit of a weird one, i always find it odd when educational videos are made with kids describing the physical properties, most surprisingly was the charge state of electrostatics not acknowledging the equilibrium state or ground state for leading into chemistry and missing the reason why different materials will loose or gain electrons when work is done, however these types of videos are most valuable for teaching kids some applicable keywords and imprinting some basic geometry more then anything. Keep up the good work Fran!
I can not ansvear, but if it is an actual place and not just a screen picture, a possible clue where to begin the search would possibly be that they either just filmed in an existing spot, like some laboration room connectod to a highscool or something like that (i hawe seen that being done a lot in British educational videos med for national TV shows, particulary whan it come to cheistry and HV demonstrations, same thing in Sweden whan we still had that national HV facility in the 1960-70s.), another option could possibly be that they did put together old equipment found in the storage room on the broadcasting facility wich indicates it may had been things used in AD/analog film or early video equipment.
There are three identical racks of equipment, each containing a signal generator, a Hewlett Packard 130C oscilloscope (introduced in 1956, usable to 500 KHz) and some other stuff. Maybe this is in a physics laboratory at some college?
To add: the function generator is HP 202A, introduced in 1952. In the leftmost rack its output is connected to the vertical input of the oscilloscope, and in the right rack it is connected to the horizontal input. That is what is making the beams to move as we see in the film.
@@cogoid soooo nice to know :) thanks for the info! The 202A has a tremendous power transformer. I wonder why... Is it a generator with a built-in power amp?
@@KeritechElectronics The transformer does look impressively large! Yet the output of the generator is not meant to drive any load to speak of. It produces a fraction of a Watt (10.6V RMS into 4 KOhm load.)
Would have been 1977. Barr Films pumped out a metric shit-ton of educational films during this period, like “To Have a Friend, Be a Friend” (‘77). As others have pointed out, Mallory became Duracell in 1978. Director and Instructor Jim Callner did a slew of generic educational films for Barr from the beginning of his tenure at West Valley College in ‘77 into the 80s until his first “professional” educational film, “Deaf Like Me,” in 1981, which earned accolades at film festivals. (Callner is still active and currently has it uploaded to UA-cam, it’s worth a watch.) If you grew up in the 70’s, Barr Films were played on projectors EVERYWHERE: schools, churches, libraries, YMCAs, Scout meetings, locker rooms; you name it. They did some cautionary horror-show style films on bus safety, drinking and driving, drugs, and premarital sex; their bus safety film featured copious amounts of blood and screaming. They also did takes on the classics; I remember watching “The Canterville Ghost” by Wilde with their distinct logo on it at a public library in the mid-80s.
Great vintage film with highly educated and inspiring kids. They did a great job and were very well spoken. Fran I have a question for you. At 5:45 a young gal named Patty is shown in an electronics lab with really cool oscilloscopes and such. They seem to be flat panel type. Can you tell me what they all are (ie oscilloscope..signal generators etc) and are they flat panel type and how may I buy them? Also what's the little brass colored circuit junction device where she is testing different items for conductivity comparison?
This incredible footage just keeps coming!
I can't help but think all this stuff should be on it's own dedicated channel, FransArchive or something.
I would love it if there was a TV station just running all day as though we were back in that time period. I think millions of people would tune in and someone could make loads of money.
Might not be a bad idea so that the dmca noise doesn’t impact the main channel?
I'll second that.
Great stuff Fran! Thanks for sharing your film collection with us.
How's your woodpecker antenna going?
Great to find you here Paul! 😉👍 enjoying a lot your electronic teaching. it is definitely one of the BEST on the yt land professor!
The Toyota 20R came out in 1975. Looks like it's a 1977 Corona to me, based on emission hose layout.
Just posted same thought you had. I thought 20R would be the clue.
These films are such a treasure, keep them coming Fran!

Hey Fran, really digging these super old school uploads, but also missing you, spread them out so we can have the best of both worlds. Maybe?
1972 Fran. I graduated in 87 so I have a solid background in the 80s which this film doesn't have.
Fantastic video! Also that drawing of Ampere is bonkers!

Third, rapid motion in this film exhibits color separation, meaning at least one stage of the capture-to-print process was done using field-sequential media. This makes me believe the film itself is a print from a video source created from a color-sequential video camera, a technique used back in the day to directly map video subframes to film layers.
A high res Kinescope is interesting, explains a lot of the artifacts. They do show video cameras in the wide shot of the studio.
@@FranLab I like it, just as it is, keep it with all its legacy. Plus, Patty looks kinda geeky cute in this format.

This film gave me strong vibes of precursor Community Access Television
I think you are of my generation. Films like this inspired us to explore physics and technology. At the fundamentals. I fear that may be lost to the current philosophy of Instant Gratification. Just GOOGLE that answer. deep sigh...
I just turned 40 years younger just watching this :-)
Thank you. That was great.
This is how I remember education being when I was coming up through public schools. Not sure this is still being taught.
Being Not Da Momma helping Da Baby with fuzzy math, I doubt it. I had to really concentrate to understand the questions and never did comprehend the general answers. Should be called murky math.
Kids have steam now. I wish i learned the advanced stuff they have now.
Thanks
That demonstration of shorting out a fat battery and adding a scene with the disclaimer that it's at least "a bad idea" to leave it that way...
Yeah ok
Exactly. It's only going to take a few seconds to get pretty hot
@@piratetv1 When I got my first power supply to play with, at the age of 8, I one day got the bright idea to run three volts through a chain. Like a foot long. I moved it a little to see if there's any magnetically induced kinetic resistance. And I burned my fingers 😂
"Electricity, What is it?" at about 1:48 sets Alexa off.
😂
Quality, if only this was shown in the UK when I was at school.
I would go with early 70's base upon those beautiful Hewlett Packard oscilloscopes behind Patty at about 7:00 in. I still have a fantastic dual beam HP scope from that era that has the very same face plate design. I have not powered it up in years and I wonder if it still works?
They sure did like the surprise factor in those days. They let the volume rip on those static electricity demos. HAHA
@ 1:07 it shows a Toyota 20R engine, which was made from 1975-1980. Based on that and judging by the battery in that shot and the clothes and hair, probably 1976-1978. Simpler times, but I've already lived through them. Oof!
The styles and looks of the young people in this video remind me of how things were in 1976 and bell bottoms were still a thing during that year .I did not care for the circuit with a wire directly across the battery as that is a recipe for fire or explosion depending on the type of battery shorted. Try doing that with a lead acid cell or Nicad cell,good luck with that.
Right, I was thinking the same thing. I've had a used 9-volt battery exploding on me one day, that was lying around on my desk and apparently got shorted by some coins. It went off like a firecracker! 😱Don't try this at home, kids!😅
Cheers.
Terrific film. I am guessing it had to be made in about 1982 to 1984. They showed a quartz clock movement in the film. These were made after 1980 if I recall correctly.
Wow...frantastisch.
Greets from Berlin .
love your channel....
THANKS! WOW! ❤🧡💛💚💙💜🤎🖤
Nice dip into the past!
Bit of a weird one, i always find it odd when educational videos are made with kids describing the physical properties, most surprisingly was the charge state of electrostatics not acknowledging the equilibrium state or ground state for leading into chemistry and missing the reason why different materials will loose or gain electrons when work is done, however these types of videos are most valuable for teaching kids some applicable keywords and imprinting some basic geometry more then anything. Keep up the good work Fran!
long live the three two telecine pull down!
I wonder about the equipment behind Patty - especially the scopes. Any clue?
I can not ansvear, but if it is an actual place and not just a screen picture, a possible clue where to begin the search would possibly be that they either just filmed in an existing spot, like some laboration room connectod to a highscool or something like that (i hawe seen that being done a lot in British educational videos med for national TV shows, particulary whan it come to cheistry and HV demonstrations, same thing in Sweden whan we still had that national HV facility in the 1960-70s.), another option could possibly be that they did put together old equipment found in the storage room on the broadcasting facility wich indicates it may had been things used in AD/analog film or early video equipment.
There are three identical racks of equipment, each containing a signal generator, a Hewlett Packard 130C oscilloscope (introduced in 1956, usable to 500 KHz) and some other stuff. Maybe this is in a physics laboratory at some college?
To add: the function generator is HP 202A, introduced in 1952. In the leftmost rack its output is connected to the vertical input of the oscilloscope, and in the right rack it is connected to the horizontal input. That is what is making the beams to move as we see in the film.
@@cogoid soooo nice to know :) thanks for the info!
The 202A has a tremendous power transformer. I wonder why... Is it a generator with a built-in power amp?
@@KeritechElectronics The transformer does look impressively large! Yet the output of the generator is not meant to drive any load to speak of. It produces a fraction of a Watt (10.6V RMS into 4 KOhm load.)
Would have been 1977. Barr Films pumped out a metric shit-ton of educational films during this period, like “To Have a Friend, Be a Friend” (‘77). As others have pointed out, Mallory became Duracell in 1978. Director and Instructor Jim Callner did a slew of generic educational films for Barr from the beginning of his tenure at West Valley College in ‘77 into the 80s until his first “professional” educational film, “Deaf Like Me,” in 1981, which earned accolades at film festivals. (Callner is still active and currently has it uploaded to UA-cam, it’s worth a watch.)
If you grew up in the 70’s, Barr Films were played on projectors EVERYWHERE: schools, churches, libraries, YMCAs, Scout meetings, locker rooms; you name it. They did some cautionary horror-show style films on bus safety, drinking and driving, drugs, and premarital sex; their bus safety film featured copious amounts of blood and screaming. They also did takes on the classics; I remember watching “The Canterville Ghost” by Wilde with their distinct logo on it at a public library in the mid-80s.
PRICELESS!
Excellent explanation. Well done
See kids? Science used to be creepy! But true to the best of their ability at the time. :)
1:07. Toyota 20R engine. So at least 75 forward.
Love watching these.
Nice Work !!!
WTCrap is up with the background music from 2:30 to 3:30?
Great vintage film with highly educated and inspiring kids. They did a great job and were very well spoken. Fran I have a question for you. At 5:45 a young gal named Patty is shown in an electronics lab with really cool oscilloscopes and such. They seem to be flat panel type. Can you tell me what they all are (ie oscilloscope..signal generators etc) and are they flat panel type and how may I buy them? Also what's the little brass colored circuit junction device where she is testing different items for conductivity comparison?
Awesome! I was expecting some Boards of Canada riffs at any moment.
That's a fun film. There are probably still using it in somebody's classroom. It did not leave anything out that is relevant today.
