Measuring: SURFACES AND VOLUME PART 1

Hello everyone!

📽️ In today's post, we will comment on the second video: Érase una vez... Galileo. This video lasts about 25 minutes. Unlike the last video, in this one we are not going to find out specific contexts talking about measurment issues, but we, as a teachers, have to think about a way to introduce the topic, and in the following lines I am going to give you some clues to do it. 

First of all, we must create a context where we explain our students that the video that we are going to see speaks about several important and transversal contents between subjects but that at the end of it we will focus on one of them.

This time our friends will not travel anywhere, but the Teacher will be in charge of explaining who Galileo was and what he did to be so famous in the world of mathematics, all this will take us to the topic of flat surfaces and volumes measurements.

In this class we will do games and activities to introduce the topic to the students. All the contents in the video are related with the history and natural science subject, so you can mix the classes so as to the students do not lose the motivation but to review and learn new contents. In addition, we will do 1 experiment, as in the previous classes.

After watching the video it is important to make an introduction in the topic, it is necessary to explain the contents that we will deal with. For that reason, we can use this web page where the measure, surfaces and volumen are explained, so we can explain in a brief introduction how we will do the exercises below.

📝 ACTIVITY 1: once the students have done several activities on the subject and know how to do the different areas and volume of the different bodies, we will work on the video and the contents that it offers us. For the first activity that we are going to do, we will use the methodology based on cooperative work, where group students will look for the different inventions created by Galileo and therefore appear in the video, which are the pendulum, the proportional circle, the telescope and investigations on spherical bodies. For them we can make use of a WebQuest created by ourselves or that maybe the students can create it, again, making use of the transversal contents within the curriculum.

Moreover, I leave you a web page where we can find some of the discoveries as well as if explanation.

📝 ACTIVITY 2: for the next activity we will create our own geometric bodies using some established measures. In this video we can find a brief explanation of how we can do it, and also in this post of another blog of mine you can find more games, activities and experiments related to the same topic. In order to make reference to the measure, when creating the bodies we will give the students a series of established measures, that is, we will say that the area should be 4 cm², for example. In the same way, we can give geometrical bodies to the students and that they calculate the measures with which we are working.

I hope you enjoyed this entry and you have accompanied us to the stars!
