We learned about earth’s magnetosphere. It comes from the outer core and protects us from solar winds that blow particles at the earth. Our magnetosphere blocks the particles except for sometimes it doesn’t. Then the particles get into our atmosphere and make light shows called auroras (by Joel,7).
NASA just recorded the sound of the earth coming from the magnetosphere. It is called Earth’s Chorus and it sounds like birds chirping. Chorus waves might carry killer electrons which are dangerous for astronauts. You can listen to Earth’s song here. (by Titus, 8)

Friday’s Factoid 9 (by Titus and Joel)
The Earth is the most special planet in the whole solar system and the only one people can live on. It has just the right amount of everything like sunlight, gravity, atmosphere, tilt and spin so that people won’t freeze or burn up or starve or fall off. I am glad we live here but I would like to visit another planet too (Joel,7).
The Earth is in the Milky Way Galaxy. The Milky Way is a Spiral Galaxy and our solar system is not in the middle. It is more on the edge. The Milky Way is over 100,000 light years across. A light year is almost 6 trillion miles. There are no pictures of the whole Milky Way because no one has been out of it. Once, the Voyager took a picture of the Earth from 4 billion miles away and it was just a little dot in the middle of a sunbeam (Titus,8).
Friday’s Factoid 8 (by Nate!)
Venus is my favorite planet because it has lots of volcanoes. I like hot lava. Cold lava turns into rock. It is called A’a in Hawaii and there is a volcano with lava here too. I have seen it. Venus shines bright even in the morning because it is covered with lava. I have seen Venus the most because I wake up the earliest of all. We made pictures of volcanoes (Nate,5).
Teacher’s Two-Cents (by Mom)
Titus and Joel took a break from writing today’s Factoid since Nate begged for a turn to write (or rather dictate) about his favorite planet. And yes, he probably is better acquainted with it than anyone else since he does habitually rise at the crack of dawn. As to his theory of extreme luminescence being due to the presence of lava on Venus’s surface, that is doubtful at the very least. But hey, we’ve heard a lot crazier than that from the science crowd, haven’t we?
