Today, we talked about the project. In groups, we have filled a paper and we have written all the details or ideas about our project. We also had to specify the materials and budget for the project to the team in charge. 

Then, we have continued with the lesson, talking about air pressure. The air is made of small particles that collides with other particles or hit with the surface. Air pressure is measure with a barometer. We can make a barometer if we want, like a voluntary activity, and upload it to the virtual campus. 

We also talked about humidity, which is measure by a hygrometer, and is the it is the amount of water vapor in the air. Humidity can be measure in an absolute or relative way. 

When temperature increases the amount of water vapor increases as well. On the other hand, we talked about wind, which is the horizontal movement of the air.
