Time: resources to measure it

I  have decided  to talk about the resources to measure the time because I believe that is very important that students get to know and understand it very well.

So, I think that a good way to explain the magnitude of time is to use a lot of different resources to measure the same thing.

On the first hand, its important to remember that we can talk about a lot of concepts when we talk about time. We can measure seconds, minutes and hours, but we can measure days, weeks, months and years too. So, we can work a lot of things with all these concepts.

Talking about the resources to measure them. We shouldn't forget mention the calendar or the clock (analogical or digital). But we have a lot of different tools that can helps us to teach these concepts. For example, we have the hourglass, with which we can teach the pass of the tiempo in a visual way.

In addition, we have the solar clock, that can helps us to make students have another vision of the time, directly related with the nature. So, they would see that the time its a "natural magnitude", that is not only an invent from the human.

Finally, we can work other concepts related with the time, like velocity, using a cronometre to measure it.
