now how about a broader field of biology leaving the human body and going out into the world the things that young people seem to ask about plant life so important in botany and agriculture and in the subject of biology how to plants grow how do they reproduce themselves here's a plant in back of me it's growing as we watch it and at some point it will find some way to reproduce itself here's a packet of seeds the key to plant reproduction lies here these seeds in some way produced by the plant dispersed by and yet they sit in my hand shrivelled almost meaningless things and if you planted them in a classroom you need a twenty four hour shift to see them turn into a plant then in turn make seeds and disperse those we made a film about this twenty years ago and our technological skills in filmmaking improved them so we've produced the second edition here's another way a film lives forever in a sense all those old first editions come back to us now with a camera man a new skills we make a brand new film and trade it for the old one something by the way that doesn't happen quite frequently in libraries and with books let's take a look at se dispersal as the camera man with his unique skills sees it in the magic of the time lapse camera the silky haired seed of the milkweed is like a parachute wind whips it from the planned and sends it sailing away it made travelled a short distance are many lapse camera to watch a bean germ traditionally teachers have investigated the community by taking their classes on field trips with all their interruptions in routine and discipline and the time that's lost from the teaching process itself but suppose you wanted to take a class to investigate the health of the community what one place would you take them to where would you go to how the many people involved in defending the health of the community work together this is one of the contributions the film maker also delivers to the classroom  synthesizes time and space and shows within the framework of a few minutes the interrelation of all the people who fight to protect the health of the community here using another one of his skills them on time he shows us quickly and effect y within a single moment of most informative film how the community defends its health protecting the health of an entire town requires the work of many people volunteer workers in your town mayor arrange meetings where parents with young children can talk with the town doctors here a mother can see how her child is growing and learn the best ways to keep them healthy if you are handicapped you might find that your town has special classes for handicapped children the town mayor arrange for a chest x rays which can detect diseases whose symptoms are hidden from view the x ray takes only a few seconds but it can help to discover certain diseases in their early stages when they are easier to cure your town may also provide visiting nurses who go out to homes where people need care for injuries or illness but if you had to you could frame a series of field trips that would get you around to see the sites involved in studying the health of the community but when you leave the community in the neighborhood and town in the area in which you live then of course the field trip disappears as a possibility yet the challenge increases every year to understand the world around us the other countries how people live to get some understanding of the problems people face to live in lands we may never visit in all our lives these are people we have to deal with in this new kind of global society in which we live how do you get a class to prove to the m d s to twelve thousand feet up in the air cameramen doesn't my visiting it for them by seeing the community through their eyes by wandering through the marketplace and into their homes by studying their activities by showing children in the united states what a boy in peru does in school how he helps his father how a little girl helps her a man and a woman do in a family in peru here's just a bit from a film on peru made my want of the travelling camera man who bring the science back to american classroom every day the village sh herded to the pasture by the lake at sunset they are driven back to the village sheep are the greatest source of wealth for the village their wool is the most important export of the indians in southern peru in spite of bright sunshine the mountain people dress in heavy woolen clothing because the mountain air at this height is always cool weaving is truly an indian craft indians invented methods of weaving before the arrival of the spaniards their looms are still crowed but their hands are quick and skillfull from long practice each village takes pride in its original designs and patterns these change little through the years house is large enough for both the younger and the older members of the family ordinarily the grandparents ate with their children on sunny days males are eaten out of doors food consists mainly of boiled potatoes and some cheese like most people of these highlands both the older and younger junkies chew the flavorful coca leaves coca leaves are a mild narcotic which reduces the sensation of hunger or fatigue so the camera sees beyond the horizon into lands we wouldn't otherwise see we've seen it look inside of solid objects and view the insides of the human body and make meaningful the process of nature what about things that happened long before we were born things your eyes might have to learn about only by reading because they happened so long ago that no one is now alive or can tell you about them in the camera turn its eyes back into time yes it can hear a whole new range of talents comes in being the educational film produces ability to recreate in believable form the events in history those things that happened through a man's existence on earth that bring to us today th tradition which is so meaningful to us which we have to understand if we don't understand how the world got this way and where it might go from here on here with great skill the camera man dresses sets finds exactly the right costumes the right artifacts the right words for skilled actors to say to give us a chance to live again in the events of historic time one of the great such experiences as a film made a few years ago by john barnes a sensitive producer who went to england to produce an image of the pilgrims for schoolchildren all over the world this isn't the traditional program film you might imagine the buckle shoes in the fowling piece over the shoulder in the turkey at thanksgiving it gives depth insensitivity and meaning not just to the pilgrims and their celebration of thanksgiving but to the extent to which man will go to defend his rights the amount of suffering he can endure for goals he believes in and understand hope to teach tolerance if we hope to give some sense of what people were willing to suffer to found our country and our traditions perhaps we have to do it this way here is just one scene man from the pilgrims i was moving and enjoyable to learn from teachers and from students that learning by film is an enjoyable process even though the subject matter in itself is an entertainment but sometimes the film becomes just a sheer pleasure this is especially true when it goes in the fields of enjoyment such as music in the arts you don't think of the motion picture as a way to develop music appreciation we're accustomed in school to sitting back and listening to records and in this day of high fidelity we think perhaps this is the best way to communicate music yet let's take a look at how meaningful and our deeply involved you can get personally in a motion picture about music in the over a church or the opera marriage of figaro the immortal austrian composer mozart plays the violin and the would win against each other laughter that it's almost a shame for me to have the last word it's been the film clips in this motion picture that i've told the story and told it far more effectively than i can with this illustrated lecture which is my part of this total presentation just as it's always been the films themselves in the hands of alert to interested and forward looking teachers that have made a great contribution to some of the things we've been able to do in our classroom using modern communications techniques there's a real message of this film that these tools have been created they are available to all peoples everywhere they have a place in every classroom they can be made available never before in the history of our country has our society turned its back on a challenge to use the modern devices the most advanced techniques to solve its problems certainly in education we have a critical problem and certainly in education we will make our greatest contribution to provide to those who deserve the most our teachers the tools that help them do the job that's so important to us
