    Morning everyone. I have a strange question. I'm putting on a program for 1st through 5th grade kids, titled "What time is it. Most kids today can not tell the time on an analog clock. So I'm just going to build a large dial face with hands attached out of 1/4" masonite. That way I can set a time i want them to read or have them set the hands to a specific time. My question, is there a way I can gear the minute hand to also turn the hour hand? I have not figured out if it can even be done without extensive gearing. I could just put both hands on the masonite dial and both hands would have to be set to what ever time, which is probably what I'll do. Just interested in what others have to say. Thanks in advance.

    Hi Ed
    My first thought was that moving the hour hand to the right spot would be part of the learning curve if they were having to get up and do it, following an enthusiastic raising of the hand to volunteer.

    Thanks for your input. I agree with you in letting the young people set both the minute and hour hands. I'm also looking at the possibility of making the dial on a white board, an then have the boys and girls actually draw a specified time on the clock dial with a dry erase marking pin. So I just may make up two dials.

    Take the motion works from a scrap clock. You could put whatever
    sized hands on it since it would not require a clock to drive it.
    To keep the kids from changing the hour hand, used a piece of
    clear plastic between the hour and minute hand so they can
    only turn the minute hand.
    I've found that having the kid place the hour hand for say 10
    minutes after the hour has been confusing for the kid. They
    have no idea of the proportion of the hour it represents. I think
    they'd get more learning out of a clock works and then they'd
    be able to copy it to some paper clocks that they could themselves
    draw the location of the hands.

    Part of our presentation is that we will have two clear plastic clocks that they can wind up and see the working motions of how a clock works. We will also have different type of clocks as well as watches. The intent here is to help the young people learn how to tell time with out having to look as a digital clock or watch. Besides using a white board for them to draw a specific time, I'm also thinking of using an old quartz movement on a white board, which would allow them to move the minute hand and have the hour hand advance as it should. I'm getting some great ideas here.

    Ed, don't be so sure these children will have a real under of time regardless of it being digital or analogue. Back in my teacher training days I presented a similar lesson to a class of 3rd graders. While all of them could read a digital display and tell you what it said, they had no understanding of what they were reading. Most of them didn't know there are 24 hours in a day or how that related to the time they were reading. It is a fun can of worms you are about to open:). Good luck!

    You raise a good point in that they really don't know how to relate what they are seeing on the digital into real time. It will be something that we will need to add to our presentation. Thanks again.
