Today we have started the part of the unit "Seasons and climate". In today's class we have seen and analyzed important concepts such as Equinox and Solstice, it has been quite difficult for me to understand them since it was the first time that I saw them explained in such depth. - Equinox: same day and night lenght - Solstice: greatest difference between day and night lenght In this picture you can see everything perfectly explained. In order for us to understand it, we performed a dynamic with the flashes of our mobiles, in which depending on the position and distance at which we placed the mobile we can observe the amount of light and illuminated spaces that are in both of them. We also talk about the seasons and how it affects the Earth being placed on an axis. Finally we have mentioned and talked about the coordinate by which the sun arises and depending on it, find out if it is morning or afternoon and what season we are in.
Today in class, Irene has divided us into groups, with the aim that each group read and report on a different topic. The first group has explained why when it is dawn or dusk we see the sky in different colors. The second group has explained the different types of pollution that exist in the atmosphere. At the end of the class Irene has highlighted some important definitions: - Daily temperature range - Daily mean temperature - Monthly mean temperature - Annual mean temperature - Annual temperature range
In today's class we have started with the topic of "Ecosystems" We have seen some important concepts such as photosynthesis, which is a chemical process that takes place in plants with chlorophyll and that allows solar energy to transform inorganic substrate into organic matter rich in energy. Before all this, we have checked a test that Irene sent us in the previous class related to topic four related to sustainability.
