e e for e now you can hear me that's weird I'm going to mute the first part of this film because it's got double perfs and um it's very loud but this is animal behavior the mechan mechanisms of imprinting this is where it's going so I'm going to mute that for [Music] you from the first hours of Life ducklings recognize their mother and follow her everywhere do they know her instinctively are they born to accept only adult Ducks as parents scientists once thought so until certain contrary observations caused a revision of their thinking does the color sound or texture of a toy affect the experiment to find out it's repeated with a different object and a second duckling again the duck is 10 hours old and the toy the first object it's seen and again the animal peeps contentedly approaches follows and responds to the toy as it would to a [Music] parent duckling 3 Experiment three the first two used toys that made sounds to see if sound is significant this experiment uses a silent toy though the balloon is silent the duck's behavior is the same duck meets object duck follows object duck adopts object and gets Mighty upset when the object disappears again the duck searches for the object when it returns there's no question that the duck recognizes it on site what if the object isn't a toy at all but a rabbit minding its own business well here comes duckling number four fresh from isolation what will happen when it meets the seemingly skeptical Cotton Tail another time-lapse sequence gives the answer [Music] despite the rabbit's initial reluctance the duckling prevails and in the process repeats the behavior pattern shown in the first three experiments the pattern can be observed with almost any object be it live or mechanical noisy or silent regardless of shape when it's the first moving thing a duckling sees the duck approaches follows re recognizes and soon depends on the object as it would on a parent this Behavior pattern is what's meant by the term imprinting to Conrad Loren who first observed it imprinting proved that while Ducks seek a parent by Instinct they come to recognize one only through learning Loren also found that imprinting has limits this duck is not 10 but 30 hours old watch the result as it meets the mechanical mut from experiment one would you call this approach following attachment hardly the 30-hour duck wants nothing to do with the toy so this experiment's result is the direct opposite of the first ones even though all that differs is the age of the duck what happens if we try it again with a different toy and another 30-hour duck scared you bet these experiments show that imprinting must occur during a certain time span or it won't happen at all the span is called the critical period it begins 3 hours after birth and ends at about 30 hours at a peak age of about 16 hours a duck will imprint more easily and quickly than at other times during the critical period once imprinting has occurred will it last this real duck has firmly imprinted the mechanical one the two are colorcoded and the duckling joins some others that have been exposed only to each other Watch What Happens 24 hours later even after a day the duckling recognizes the toy not only does the imprint last but appears every bit as strong as it was 24 hours before and notice what's happened to the rest of the brood having been together throughout the critical period they've imprinted each other once a duck has imprinted one toy will it shift its preference to another to find out a second duck gets a neck tie so does a third once again watch what happens after 24 hours when ducks and objects are reunited [Music] a [Music] [Music] the result is clear each duck has formed a detailed enough image of its own toy to remember and distinguish it from the others the learning that results from imprinting is not only lasting and firm but astonishingly precise [Music] what happens in the laboratory also occurs in nature newborn Ducks seek and follow the first moving object they see which usually happens to be their mother within hours of birth the ducklings have a firm attachment to her and a lasting precise image of how she looks they keep her in sight assuring themselves food warmth protection and a guide back to the [Music] nest imprinting has also been seen in other animals that can walk soon after birth to scientists imprinting is important as a link between Instinct and learning as for the animals themselves it's a behavior that helps ensure their very survival [Music] all right let's see if we can get the uh are we there yes uh OBS uh which is a wonderful open source program sometimes just has a freak out and um yeah it was not uh the for some reason the uh microphone was having problems which is very annoying and we hope that that is not what's going to be happening in the future because obviously we hate that uh so we went to I went to um a conference last week the orphans Film Symposium and saw a bunch of films um and one of the things that's clear is um people find these film artifacts either they were finished pieces or they're raw footage or whatever and then they try to understand them and so that's what we tried to do here is understand movies and maybe this awesome film will help enjoy [Music] and as part of a continuing program of surveillance and intelligence you will proceed to the designated area the objective is the safe indicated in your initial briefing empty entire contents of the safe as it is necessary to establish burglary as the motive warning Ivan rojack a danger counter agent is aware of your presence in the area if you encounter him or in any way suspect that you or your intentions have been discovered immediately abort mission for your own protection withdraw to security Area 3 [Music] for [Applause] [Laughter] [Applause] [Music] [Music] all [Music] [Music] [Music] [Music] oh [Music] there is a good chance we have all seen dramatic stories like this before some of us many times at the beginning of mystery shows on television or in movie theaters so it is quite familiar and we can all understand what's happening in fact some of us are so at home with this little episode that we have come to accept it as almost natural in a way almost real just how real are movies how natural are they how much do we really understand about how our agent gets about and what is happening to us in the process you will find that in terms of your own natural sense of proportion and time almost everything in this film is unnatural and a physical impossibility time as we know it and time in the movies are not the same let's take a look at some of the ways in which movies deal with time our agent gets into his car and takes off he travels to another section of town climbs a fire escape breaks open a window climbs in and closes it searches for and finds a safe as you see by the clock all of that took 44 seconds of movie time but in our time or our reality it might have taken 20 or more minutes for the drive to the factory area at least 5 minutes to locate and climb the fire escape another 5 minutes to investigate and break in and let's say 4 minutes to search for and locate the safe movies compress or squeeze time in 44 seconds the movie has accomplished what in reality would have taken half an hour or more here's another example of compression of [Music] time let's look at it again and examine it a little more carefully we see one picture and sound go away as another picture and another sound move in to take its place [Music] a lot of unreality can happen in less than a [Music] second movies can also expand time or slow things down even stop time so we can examine a particle of time hundreds of times longer the normal here is another example of expansion of time let's run it again and stop time so we can get a look at what he's thinking here is how we saw it in the picture here we expand distance as well as time our agent is falling in slow motion four times slower than normal to to make his fall seem even longer we see the same thing three times from different places here are a few other unnatural things movies do to us they make us see things larger and closer than humanly possible and hear things louder than normal [Music] [Music] in life we select the sound we want to hear out of all the noises around us in movies all the noise is eliminated except the sounds someone else selects for us to hear sometimes we hear sounds we don't normally hear without special equipment that is in the unreality of the movie we the audience perform physical impossibilities we are propelled about it great speeds moved instantly from here to there if you think our friend is moving fast how about us here we are standing on the sidewalk watching them run down the street when suddenly we find ourselves down down the block with our eyeballs sitting on the ground watching him run right at us look out saved we have been instantly placed out of harm three stories up but oops here we go again now we become the man we jump into his skin and run along with him we really travel as we sit here as a matter of fact in this short drama we could have traveled over 100 miles at varying speeds taking hours or even days all in less than 4 minutes if you want to look at it that way in our search for reality or non-reality in film we have examined some of the bits and pieces that deal with our own sense of time and proportion but who is to say that these elements these bits and pieces were arranged correctly in the first place rearranged they might present a different kind of reality w [Music] [Music] because movies so greatly affect our lives what we buy how we vote the causes we support how we relate to other people and our lifestyles in general it is important to understand movies the next time you see a motion picture keep in mind your own sense of time space and proportion so someone pointed out nervous nervous transfusion using that popular tire squeal all right what do we got what do we got what do we got um we uh it's not at the archive but where Katrina and I live uh is near Two Lakes two small lakes uh but we have herens lots of really awesome herand so here's a short film about the great blue heron which I think we have some but we also have some green herand and we also have a bald eagle which is really awesome uh which shows up occasionally so here's the great BL Blue Heron the great Brew heron for for each year in late February I come out to this Missouri Wildlife Refuge to study one of the most beautiful and least understood of American birds the great blue heron in the next few weeks between 1 and 200 great blues will migrate here from the south to reclaim the remnants of last year's nests [Music] [Laughter] [Music] in early March the first males begin arriving after a short period of wandering over the heronry the males choose trees for nesting the females will fly up later [Applause] oh [Applause] every year I've come here there have always been more male heroins than available nests consequently the males compete for the nest the best and highest nests going to the strongest and most aggressive males to get a nest the male must violate the territory of another male Heron the territory includes not only the branch he stands on but the airspace around it trespassing often insights a Pursuit flight to decide who gets the nest this preading competition for the available nests helps to make sure that the strongest and most fit males will reproduce young the loser must try again or start a new Nest from scratch by the end of March all the nests have been taken by the strongest males and the waiting Begins for the first females to arrive [Music] oh oh [Music] once they've made it the two herons will remain together for the whole season the male does most of the stick Gathering while the female places the sticks and prepares the nest for her future brood a month later in mid April I think I can hear the newborn chicks but I'm not sure the angle doesn't give a good view into the nest I wait a few more days before deciding they probably hatched the best way I can find out is to climb the tree [Music] my two herens live in a stand of sycamore trees in the middle of the Refuge to get up I use ropes thrown over the branches above after 2 years practice I can usually get to the top of one of these 120t sycamores in about a half an hour one of the reasons so little is known about the great lose is that it's so hard to observe them another reason is that they're extremely wary of humans and for good reason we are the main threat to their survival many thoughtless Hunters consider them fair game even here in the wildlife refuge and as we build more and more houses we take their land and drive them away the great Blu is always build their nests on the weakest and least accessible limbs to protect them from any Predators coming up the tree well I was wrong they haven't hatched yet I'll come back tomorrow they're born with their eyes open but almost helpless my her in family is a typical size at Birth they have just a sparse down insulation which makes them vulnerable to any cold weather 3 Days Later an April snowstorm hits our refuge [Applause] [Music] [Applause] [Music] yesterday's storm took its toll and all my nestlings died now the parents have to start over again through May and June I continued to check the nest from time to time all of the nestlings are doing fine except the last one hatched the rent week from the start he hasn't been getting a share of the food usually in nature the weak do not survive Only the Strong but in this case nature made an exception and the rent lived by mid June the nestlings are trying out their wings in the nest the parents begin to feed the young less often encouraging them to feed on their own the aggressiveness of the young at meal time now makes feeding by mouth more and more difficult so the parents just dro the food in the nest this period when the nestlings are learning to fly it's particularly dangerous for them and their mother knows [Music] it graceful as they are even the adult great Blues have difficulty maintaining their balance in the trees even in light breezes these creatures will occasionally miscalculate Landings if a fledgling falls from the nest and lives the adult herons won't risk going to the ground to feed and care for it the forest floor has too many predators the fledgling must fly or die in their first year of Life about 70% of the fledglings die but life goes on and the young fledglings continue to practice flying in the nest and on nearby branches by early July after 2 months of Nest life the fledglings are ready for flight soon the young herons will make their first flight South when they return if they survive I'll be returning to do to study them [Music] uh thank you Jeremy and burrow Al for donating uh via the super thanks button that's a great way to support us uh and that money goes for pain for things things [Music] like uh what's a good example oh yes um USB hubs so uh when we buy Mac hardware they are getting less and less ports and basically going for some sort of USBC or Thunderbolt which means that all these other things like uh this traditional USB HDMI um Network um SD cards all that goes away so buying a hub helps us continue to support Legacy things uh Apple likes to get rid of things well before they should um so anyways technology uh behind me is a film scanner and we have a film called On's a heer um see if you can figure out what this is about enjoy [Music] get in there come on get in [Music] what [Music] ow what the was he thinking I'll

after viewing I didn't ask you the before viewing questions list all the reasons that Peter has for believing that Vickers is hiding the calves in the barn use the following list of words for vocabulary and uh spelling study Prairie atmosphere depression e eccentricity suspicion antagonism isolation suggestion loneliness heer uh go back to work oh no okay working with a a partner go back to the work you did no okay conduct a conduct a mop trial in which of Pete in which he is accused of seeing evil where it does not exist prepare and give an oral report to the class on the topic of Life as a child on the prairie farm in the 1930s uh one reason the viewer is tricked into going along with Peter's suspicion about Vicor is that we see Vicor through the boy's eyes and perceptions working in groups of three uh select a scene from the middle section of the film and rewrite it as you would would appear from vicker's point of view evaluate the scene by acting it out in front of another group group I'm sure that would be really popular uh hold a formal debate on the topic people are responsible for the Impressions we form of them uh the film takes place in 1934 in groups of four not three four research the history of that year and make a bu bulletin board display to show major events and developments that affected International policies North American society and Prairie farming uh read grapes wrath a report on the class this novel's relevance to the study of people events and literature of the Great Depression research in literature uh in the literature of sociology and or psychology some of the effects studies of the effects of isolation on personality of an individual make a written report to be delivered with discussion period to follow wow that's a lot of work yeah all today I mean this is the deal so like you know they make these films and the idea is that they provide these teachers guides as a way to like okay well we just showed this so how can we enhance the experience and have kids uh or your students process what they just saw so there you go On's a heer uh thanks for joining us today thank you so much for donating uh and the thumbs up that
