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!

Our Solar System

For science this week we studied our solar system. Did I tell you we do science twice a week? (Well we're SUPPOSED to, and this week we did.) Well, I figured that since I was in Vanuatu for half this semester and who knows about next semester, we need to do double duty to get through the content.

The first lesson we talked mostly about planets' rotation around the sun and how gravity and the laws of physics (mostly inertia and centripetal force) effect all that. We also talked more about the sun.

As part of this we talked about how a spinning planet works like a gyroscope and gives it stability.


Friday's lesson (which I moved an hour later because I was late getting back from Lethbridge...I love the moms who are so easy going with me!) We talked a little more about the entire solar system, but then focused on the inner rocky planets. We'll need to talk more about Mars because we didn't get to some things.


And by the way, those books that were "lost" in the mail ended up being at Babb after all! So now I am definitely ready for teaching!

Constellations

We also had the FIRST science club in this house!!! We focused mostly on constellations. I thought we had some pretty magical moments. We went into my dark storage area and brought out Maxwell's constellation globe. They passed it around while I read greek myths about the constellations.


They also made their own constellations and we talked about how constellations are completely dependent on your viewing perspective. The kids had a good question: How far away from earth would you need to be before the constellations don't look familiar? I have no idea. Good science fair question.

Inro to the Universe

Thursday and Friday we're SUPPOSED to do science, but I've only done two classes so far.

The first class was an introductory to astronomy. We talked a bit about how to study stars, including how to find the North Star. We also spent quite a bit of time talking about telescopes and how they work. This of course brought up light and lenses and all that Jazz.


The other class we had, we learned about the expansion of the universe and red shift. We talked about why the milky-way looks hazy, why stars twinkle, and what makes a star bright.

We also talked about the movement of the stars in the sky, and used an umbrella globe to illustrated this:


but that's all the classes we've done because, well, MOSTLY because I couldn't get my science book! I was SO annoyed. I ordered all the books I needed to do science. I got two of them, but one got lost in the mail. I went ahead anyway, but then after two lessons I felt stuck. I ordered ANOTHER one of the same book. THAT ONE got delayed in the mail too! (still not here)

Finally our house closed and we moved all our stuff in the garage. The highlight of the move for me was to open a school box and find THIS:


Science is up and in full force now folks (ummmm except I'm gone to Calgary this Friday picking Dustin up from the airport......)

Heart/Circulatory System

We did our last science class in Cardston. It was epic. It was a last minute Halloween Party. We studied the heart, and took our pulse, studied our veins, and saw if we could move liquid as effectively/fast as a heart could (we couldn't) and then we DISSECTED TWO HEARTS!!!

One boy said "My mom would throw up if she were doing this." I personally was not squeamish at all, and was so excited by it, but I can imagine that some might not feel that way, after all, just look:


That's a cow artery.

We got a dear heart, but some of the top had been cut off (come on butcher! Don't you know this is SCIENCE?-jk)


But it was the cow heart that stole my class's heart--hehehehe, yah---

Look how HUGE it was!:


I think this is my favourite homeschool photo of myself. I debating about putting it as my Facebook profile photo hahaha.

But I found out I told my kids a fib. I said a whale's arteries were big enough to swim in. They went home and researched it, and proved me wrong....oops.

Skeletal System

For science we studied bones. That's when my favourite moment of science EVER happened. I brought out my little skeleton man and said "Bones protect our organs. Look at his head. What is the most important thing to be protected?" And quiet Hunter Blackmore shouts out:

"OUR BRAINS SO THE ZOMBIES WON'T GET THEM!!!"

Bwahahahahah! I just laughed and laughed. That was awesome.

We talked about the structure of bones, bone's joints, their strength, and what happens if you break them. We made a spine as one of our activities, and I let them take it home. It was a balloon head with a string as the spinal cord and thread spools as vertebrae and buttons as disks.


We also looked at xrays....I think my mom bought this kit for me...

Semipermeable Membranes

This week we studied the cell some more. Specifically that it has a semipermeable membrane. We made naked eggs (the scandal.)


And we put corn starch into water with iodine, but this didn't work like it has for me in the past. I guess my plastic was too high quality. The iodine was supposed to be able to go through the plastic and into the cornstarch, changing it to dark blue, but it didn't.


Oh well,
