Our Super Solar System Studies

Marvelous Mercury in Space by Lindsay
(With help from Ryan and edited by classmates)
Mercury is the first planet closest to the sun, so it is very hot. The highest temperature on Mercury is 800 degrees Fahrenheit, and the coolest temperature is -279 degrees Fahrenheit. Mercury is just larger than Earth’s moon, but smaller than all the outer planets, not counting Pluto. Did you know that it takes Mercury 88 Earth days to orbit the sun, and that it takes 59 Earth days for it to complete one rotation, or one full day on Mercury? Mercury has no moons. The closest planet is not the hottest, actually Venus is hotter than Mercury. Finally, this planet, known as Mercury, is very small, but very fascinating.

Superior Saturn in Space
by Ryan and classmates
Saturn is known as the sixth planet from the sun.  Saturn was
discovered in 1610 by
Galileo Galilei. A day on Saturn is
completed in only 10 h
ours and 30 minutes, and 1 year takes
a long 29 and one half earth years. O
ur science text book
explains that Saturn has 47 moons, but now it is said to

have 59 moons! Saturn is known for its stunning rings which
are made from ice, dust, and roc
ks that orbit the planet.
Saturn's rings are
labeled A through F. Winds on Saturn
accelerate up to a non-stop 1,100 miles per hour. All in
all, Saturn is my favorite planet in this galaxy.

by William and Brendan
The planet Earth has many extraordinary features. One example is a volcano, which is a kind of a mountain that is huge and has lava. The lava's hotness comes from the heat source of a hot core, or the center of our Earth. Just imagine this, where we live on the surface of Earth, the average temperature is 59 - 69 degrees Fahrenheit, but where the core is, it is a blazing hot 7,200 degrees Fahrenheit! This is as hot as the Sun is on the outside.

Many scientists believe Earth was made by pieces of rock colliding as they circled around the sun. This formed a mass heat source in the huge hot core of the Earth. This core is what fuels a volcano to this day. The magma, which is the lava before it comes to the surface, goes through many sections before the volcano erupts! First it transports through the large magma chamber and out the main vent. Some of the magma seeps out the side vent. After the magma has erupted, it is called lava. The lava flows down the side of the volcano. Last, but not least, it is followed by an ash cloud. All in all, volcanoes are very interesting features to explore.

Learning About Space by Juliette (Edited by classmates)

If you're looking for a fun way to learn about space, the Griffith
Observatory is the place. One exhibit is a room with models of all the planets. You can even learn how much you weigh on each planet! There is also a show about space and who discovered it. You can see pictures of things in space. For example, there are amazing pictures of Neil Armstrong on the moon, a wonderful picture of the surface of Mars, and an awesome picture of the moon. I traveled there on June 3, 2009. When I explored the Observatory, my favorite thing was when I got to see how much I would weigh on each planet. On some, I weighed less than one pound! All in all, the Griffith Observatory is the place to have fun and learn about space at the same time.

Imaginative Constellations
by Mia
(Edited by classmates)
A constellation is a group of stars formed like a person, animal, or an object. For example, in the Roman times, they believed that some constellations looked like a lion, a dog, and a great hunter. Some famous constellations are called the Big Dipper, Orion, and Little Dipper. One time I went outside and saw a constellation that I thought looked like a snake. You can also do this, all you have to do is use your imagination!

Please leave a comment and tell us something you have learned about the Solar System!


  1. Dear Mrs.Ranney's Class,

    Guess what...this is the first time that I have ever read a blog. I loved learning about the solar system. You know so much more than I ever knew when I was in school.

    Keep up the good work|

    Mrs. Connell (Juliette's grandmother}

  2. Dear Mia,

    Thanks for inviting me back to the blog. Will look for a snake in the sky once the clouds clear!

    Thank you all for very informative presentations. Nice use of alliteration and font colors, too!

  3. Dear class,

    I really enjoyed your solar system information. I am trying to figure out how a day on Saturn is 10 hours but a year is 29 "earth" years - that is interesting.

    I'm so glad that you have become interested in blogging. It is a great way to learn and share ideas with each other. Keep up with the great learning and writing!

    Mrs. Harding

  4. Dear Mrs. Ranney's Room,

    What a SUPER SOLARSYSTEM! I never knew how huge and beautiful the solar system is.

    I especcially like the volcano diagram. It was a compliment for the volcano.

    Nice job, (again!)

  5. Dear Mrs. Harding,
    Thank you for your comment. We think that it is rather strange too, that a day on Saturn takes only 10 hours and 30 minutes, but a year is 29 1/2 earth years. This means that it takes Saturn 10 1/2 hours to rotate (spin) on its axis one time, and that it takes Saturn 29 1/2 earth years to orbit the Sun!
    We hope that enjoy our future posts and comments!

  6. Dear Mrs. Ranney's class,

    It has been fun learning about the solar sytem. I loved Juliette's paragraph "Learning About Space". I bet someday I could also vist the
    the Griffith Observatory and get to weigh myself on each planet.

  7. Dear Mia,
    What is the little dipper?I have never heard of it.
    Dear room 9,
    I mostly enjoyed reading about Saturn. It is so beautifully colored. I think that Saturn looks better with it's oval shaped self. I also love that we made a post about what we are learning in space.


  8. Dear mrs. Ranney's class, It was awesome learning about are super solar system. I like Saturn because of its beautiful rings. I hope I can send Mrs. Ranney more comments. Sincerly, Alex [One of mrs. Ranney's students]

  9. Dear classmates,

    I have enjoyed learning about the solar system. I never new that all planets have differnt hours in a day! Well now I know. Also I enjoyed learning about how the planets rotates (spins). It was fun learning what Saturn's rings are made of. I hope next year I will learn even more about the solor system.

    Danielle :)

    p.s. Solar means sun.

  10. I really enjoyed learning about Saturn. I never knew that 1 year on Saturn is equivalent to an astounding 29 and one half earth years.

  11. Dear Classmates,
    I never knew that on some planets you can weigh less than 1 pound, and that volcanoes are 7,200 degrees. All in all, wen all did a fantastic job on our post and blog.


  12. Dear Mrs. Ranney's Class,
    The 180 days of school is just about over, but we have gotten to a fantastic level on our class room blog! keep up the great work!

    Dear Ryan,
    I never knew that Saturn's winds can accelerate up to an amazing 1,000 miles per hour!

    Dear Brendan,
    We did an outstanding job writing about volcanoes. I learned an immense amount about volcanoes!

    William M.

  13. Dear Mrs. Ranney's Class,

    I am so impressed by all of the writing and learning you continue to do in class! You have definitely learned a lot this year. The solar system has always fascinated me and I loved reading about Mercury and Saturn. It's amazing how hot and how cold it can get on Mercury.

    I am particularly interested in volcanoes since I grew up in Hawaii where there are still some active volcanoes. I didn't realize that lava is as hot as the outside of the sun!

    I really enjoy reading your blog and want to congratulate all of you on such a wonderful job!

    Warm Regards,

    Jaime Davidorf

  14. Dear Class, you all did a great job on making posts for this blog. I had no idea that the molten magma in the center of the earth is as hot as the suns outside.


  15. Dear Class,

    I've learned a lot from those of you who have written about our solar
    system. Learning about our solar system is very fascinating. It is funny
    how Mercury is cooler than Venus. I thought that Saturn was the only
    planet that has rings! To sum up, the "Sun" system is the largest thing
    that exists!
    Yours truly,

  16. This is a comment I am posting for Lindsay:
    Dear Mrs. Ranney and Class,
    While making the blog, we made a space post. Mia, I learned a lot about constellations, and tonight I will try to find a snake or something else! I hope all of us can keep in touch over the summer and that Mrs. Ranney will put up some posts about her summer.

  17. Dear Mrs. Ranney,

    I never knew that Mercury was the closest planet to the sun. Also, I never knew that its temperatures range from 800˚ to -279˚.
