What about today?

We have studied the concepts of seasons and climate, It is necessary to understand this topic to understand why there are different seasons and climates. This is because there are changes in the angle at which sun rays strike the surface. It changes the length of daylight. Thermal inertial and the amount of atmosphere the sun rays travel through: depletion of dunlight. It is essential the Earth- Sun distance. And the difference between north-pole winter and south-pole winter. We have spent 20 minutes working on our rubics that will have to be finished for Friday.

We have continued working in teams. The class of today has been important since we have divided the roles for the work: 1 Moderator 2 Secretary- spokesperson 3 Tasks coordinator 4 Supervisor We have completed this sheet and we have exposed it to our classmates. Then, we have decided the most important aspects that will be evaluated in our future work.

We have continued with unity and we have seen the movements of the earth. These are four: Rotation: It is a movement that effects the Earth turning on the terrestrial axis, that cuts to the surface in two points called poles. This turn is from west to east, that is, for an observer located in the space above the North Earth pole. Revolution Changes in the anle at which sun rays strinke the surface Changes in the length of daylight. Thermal inertia. Procession The procession of equinoxes is due to the movement of the extension of the earth for the movement of the force exerted by the Earth- Sun system as a function of the inclination of the earth's rotatio axis with respect to the sun. Nutation Nutation is the periodic oscillation of the Earth's pole around its middle position in the celestial sphere, due to the external forces of gravitational attraction between the Moon and the Sun with the Earth. This oscillation is similar to the movement of a...

Wednesday, 23th of January Today we have started the first theme called: Earth in the Universe. We have seen very basic aspects and other more complex to understand. A summary of the content is: The earth is a planet It is an imperfect sphere, flattened by the poles. It moves around the axis of rotation and it has a northern and southern emispher. The earth is always moving. Then, the teacher has explained us that we will have to work in groups and we will have to present and explain to our classmates a news about a specific topic which will be assigned.
