Today I'm posting some videos that we have seen in class and that clearly explain some concepts we have been learning in this unit.
This first one is your favourite, a comparison on the sizes of planets and stars of our Solar System and our galaxy, the Milky Way:
This other one explains why we have day and night, due to the Earth's rotation around its axis:
In the following video, you can review why we have seasons, due to the Earth's orbit around the Sun and the fact that the Earth's axis is tilted:
On the last video, you can review everything we have learned regarding the moon: its rotation and orbit around the Earth, its phases and the two kinds of eclipses: lunar and solar:
I hope you find them useful for reviewing and interesting to watch. You can leave your comments below.
Have a nice day!
Here I add the video that Rodrigo has recommended us. It explains the formation of the Earth and it's really really interesting, I'm sure you are going to love it. Thank you, Rodrigo!
