The rest of Astronomy

We did end up learning more about Mars. We even did this experiment where we had three jars of sand and one had a chemical reaction, one had no reaction, and the other had a reaction with something living (yeast.) This was to show how we can test for living things on Mars.


That day we also learned about the outer planets. Jupiter, Saturn, Uranus and Neptune. I had the kids learn the saying "Many Vampires  Eat Monsters Jumping Squares Using Nuts" to memorize the planet order. I know most people learned "My Very Educated Mother Just Served Us Nine Pizzas" but I learned the Vampire one as a child, so we did that one.

The next lesson we learned about other elements of the solar system. This included the outer edges of system which of course includes Pluto. We learned about it's weird barycentre and created a model (btw my phone was in for repairs, so that's why I have horrible photos.)


Also, it included comets and we learned why the tales always point away from the sun.


The next class was about space exploration. We talked about natural and artificial satellites. We talked about propulsion, gravity, and exploration. Umm I can't find any photos. I think we actually did comets this day because we ran out of time on the other day.

Anyway, next class we talked about the moon. We talked about the phases and we had ourselves be the earth, this Styrofoam ball be the moon and a lamp be the sun. It really helped bring it home.


Although our faces weren't as close as this. It was just a cute photo. Anyway, I finally realized that the "dark side of the moon" is actually lit up by the sun as much as any other side, but is called the dark side because we never see it!  I don't know why this took me so long to realize.

The next lesson we learned more about the moon, but we also learned about the earth's rotation.

IT WAS PERFECT! Serendipity often happens with homeschool. It just so happens that I got to the point in the book where we’re learning about solstices on the day of winter solstice! We also learned about the Zodiac and why the suns rays effect different parts of the earth differently. 



Our next lesson (boy, just going through all these lessons makes me realize how much science we've really done! Go us!) We learned more about the earth's rotation. We learned about different evidence of the earth being round and the sun going around the earth. We watched this awesome youtube about the earth not being flat. It talks about a group of people who insist that the earth is flat. I loved it!



We talked about sundials, and I guess you can make a compass out of a sundial, but I couldn't figure it out.



Then we went on Christmas break. I told everyone that we could only do one science class a week from now on, and it was really good timing. One: because I was getting burnt out, and two: I was done with astronomy.

The first lesson of the year was about the study of the earth . We talked about fossils and geological history. We briefly talked about energy as well because of fossil fuels.

As part of this, we made our own "fossils" by taking tiny toy dinosaurs and pressing them in play dough and then putting plaster of Paris in the indents. 




And that's it! Whoo hoo for science!
