    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.

      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 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)"

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.

    @ 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!

    • @sheep1ewe
      @sheep1ewe 3 роки тому +1

      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.

    • @cogoid

      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?

    • @cogoid
      @cogoid 3 роки тому +1

      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.

    • @KeritechElectronics
      @KeritechElectronics 3 роки тому +1

      @@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?

    • @cogoid
      @cogoid 3 роки тому

      ​@@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?
