We have done a brainstorming about the Moon:

-          Its gravity is 4,9g

-          Moon’s gravity is less than Earth’s gravity

-          It has two movements (revolution movement around the earth and the rotation movement)

-          It has phases

-          It does not have atmosphere

-          The moon does not have its own light

-          A quarter of the size of the earth

How is possible if the moon have momevent, that we only see one side of the moon?

The reason why only this face of the Moon is visible from Earth is because the Moon revolves around its axis of rotation at the same speed at which it orbits around the Earth.

In class, we have done a representation of the thing we have explained above.

• Who does de new moon looks like? The moon is unlighted
• Who does the first quarter looks like? Like a D
• Who does the full moon looks like? Lighted
• Who does the third quarter looks like? Like a C

Then, we have seen a video about the phases of the Moon

 

 

Then we have been talking about some vocabulary like crescent and Gibbons, and waxing and waming. We have related them with the phases of the moon.

 

For there to be an eclipse, the sun, the moon and the earth must be in the same place. The phases in which we can observe an eclipse are in new moon and full moon.

Seasons and climate.

Earth axis is titules 23,5º from the ecliptic plane.

• Equinox -  same day and night length
• Solstice -  greatest difference between day and night length. Autumn and spring. 

We have seen a picture of the ecliptic plane and we have been talking a bit about the axes , the movemente of the earth. 

In addition, we have been checking with the flashlights of our mobiles how if we put the light vertically or horizontally, the amount of illuminated space changes.

In our summer we are further from the sun so, this is not the cause of the distribution of the seasons.

In summer, the sun is higher. Being higger means that the sun heat more than in winter.

How can we explain the temperature differences in the seasons from outside the earth? Because the earth moves around the sun but at the same time they have a tilt ax.

Next and in relation to the above, we have seen a video that demonstrated the position of the earth with respect to the sun, solstice by solstice. We have been able to observe how the duration of the light also changes in the days, like a few days before dark and others after.

Following an illustration by Frato, who writes a lot about education, we have been talking about whether the sun is the one that moves, or is the earth. ‘Apparent path’ definition has appears; the ecliptic is the mean plane of the apparent path in the Earth's sky that the Sun follows over the course of one year; it is the basis of the ecliptic coordinate system. This plane of reference is coplanar with Earth's orbit around the Sun 

Where does the rise rise from? The east for the whole planet.

Today we have invested the first hour of the class in doing a project that the teacher has sent us about doing at scale size, the distance before the sun and the earth and Jupiter. We have gone out to the playground and we have made them

Then, we have thought about possible solutions what we can do in relation to the solutions we proposed last day to reduce the use of plastic. Possible solutions are as follows:

• Design a CES Don Bosco bottle
• Account in Instagram - raffle
• Collect signatures
• Give aluminium bottle
• Give piece of fruit 
• Questionary 
• Visual campaign 
• Workshops 
• Award (points)

At the beginning of class and given that the teacher could not spend much time in our class, she sent us a school paper.

We had to get the data of the diameters of the planets of the Solar System and their distance between each other in order to build a real-size model of the distances between each other's averages, so today's class has been dedicated to calculate distances and lengths.

At the beginning of the class, we went down to the playground and made a routine of thinking. I see, think and wonder. These have been my responses to that routine:

See	Think	Wonder
I see a wonderful landscape with lot of plants.  Today is such a sunny day.  I can see some trees without leaves.	I think that today it is not going to rain because the sky is without clouds  I think that today is not a typical day of february	I wonder why it is so hot when it is only 5th of february I wonder which part of the universe is that plane going to I wonder why nature is such an amazing thing.

Next, our group has talked a little about the following questions:

•Where we are?

We are in the universe, in the solar system as well as in the earth, also in a country called Spain and in a city called Madrid. If we think about this moment, we are in Francos Rodríguez, at the University of Ces Don Bosco.

• Where does the information from the universe come from?

Information comes from everywhere, all we see is because the universe influences every matter.

• What is the universe like?

The earth is like a sphere with different colors among which we find blue, green, brown and white. This is due to the ecosystem. There is more water than anything else on earth.

Then we started talking a little about the beginning of the first unit. We have talked about earth movements and finally, each group has read an article in relation to plastic.
