EARTH SCIENCES

Today we started the class all together to solve some doubts. After it, we had a videoconference with our groups in which the teacher asked us what we have improved about the project. We have been analyzing the results of the 112 ansers we obtained with the questionary. Also we did the new chart for the roles. We took photos from every group reunion in order to make the final video at the end.

Today we had a videoconference by zoom in which we asked the doubts we had about the homemade cloud or the weather instruments.

During the first hour, as the screen was not working we had time to work on the proyect with our groups. Our group ( as we are coordinators) asked the classmates to do a list of the materials they need for the proyect. Also we used this hour to organize the cuestionary and select the questions the classmates sent us. During the second hour, we keep going with the unit. Air temperature - Daily temp range. It is obtained substracting the daily minimum temp from the daily maximum. - Daily mean temperature: average temp between the maximum and the minimum for each day. - Monthly mean temp: calculated by adding the daily mean temp for each day of the month and dividing by the number of days. - Annual mean temp: average of the twelve monthly means. - Annual temp range: Is computed by finding the difference between the warmest and the coldest monthly mean temp. Factors of temperature - Seasons - Latitude - Differencial heating of land and water - Ocean currents - Altitude -...

We were divided in groups to finish discussing the topic wenhad read. Our topic was air pollution. After it, two people from each group had to come to the blackboard and explain their topic. Air pollution There are primary gases, which are our responsibility ( example: the smoke of the cars) and when this gases go up to the atmosphere, they mix with the particles and form the secundary gases. The secundary gases are very dangerous to the ozone layer . Although we do not make the secundary directly, they are our resposibility. Why we see the rainbow? Why the sky is blue? - Wavelenght - Scattered- the light does not go directly - The direction of the light - The lights of the sun has every color but the earth absorb everything except pink, so we have pink sky. CFS When sunlight comes, the CFs divide into atoms. The atoms reduce the Ozone so we are less protected. The ozone holes are at the poles because we have there less amount of Ozone.
