Friday Factoid Week 9

Click here for a Flashback to what we were learning in our Hawaiian homeschool 6 years ago this week.

And click here for another Flashback that has to do with today’s topic.

Teacher’s Two-Cents

I haven’t added my two-cents to a Friday Factoid for a long time, so I’m doing one now and also giving the boys a break since you have 2 Flashbacks to nibble on and they’ve had a crazy busy week.

So I want to add my two-cents to the second Flashback above about the magnetosphere and the auroras it causes and this time my two-cents comes straight out of the bank of Job.

“Hear this, O Job; stop and consider the wondrous works of God . . . Can you, like Him, spread out the skies, hard as a cast metal mirror? . . . And now no one looks on the light when it is bright in the skies, when the wind has passed and cleared them. Out of the north comes golden splendor; God is clothed in awesome majesty.”

Job 37:14-22

Job is one of my favorite books in the Bible because I’m always amazed at the depth of scientific knowledge people of his time had and the conclusions they came to about God through what they observed in nature. They truly believed God made Himself known through creation.

The passage quoted above is a great example of that. It might sound very primitive and ignorant to our ears to hear an ancient person describe the sky as “hard as a cast metal mirror.” But when you think about the earth’s magnetosphere, that description actually makes a lot of sense!

The entire earth has a magnetic field surrounding it and its job is to pull harmful particles produced by solar winds away from the earth or reflect them back toward the sun. Sounds a bit like a mirror, right? The sky may not be hard as a cast metal mirror but it certainly has the reflective, metallic-like properties of one.

And what about that light people of Job’s day seemed afraid to look upon when it shone brightly after the winds cleared the skies? Where did that golden splendor come from? “Out of the north!” Sounds a little like the Northern Lights, the Aurora Borealis, doesn’t it?

And do you know what causes those auroras? The presence of that reflective magnetosphere of course! Some of those harmful particles from the solar winds get trapped in the magnetic field and crash into our atmospheric gases causing a beautiful light show.

Events like those should do nothing less than inspire us, like Job’s friend, to “Stop and consider the wondrous works of God.” He is indeed, making Himself known through them!

Friday Factoid Week 8

There is no atmosphere on Mercury which means it is very hot during the day and very cold during the night. Venus however, has so much atmosphere it remains 870 degrees all the time. The atmosphere is made of thick, lightening producing clouds of sulfuric acid moving at 220 miles per hour.  Also, my mom said to add this link to an old post (Titus, 14)

A day on Venus is longer than a year. It takes Venus 243 earth days to make one rotation but it only takes 225 earth days for it to orbit the sun. It also rotates in the opposite direction of the earth.  Here is a link to some silly things I wrote about Venus when I was 5 (Nate, 11).

Venus is the Morning Star and Venus is the Evening Star and it is so bright it can make shadows and it has volcanoes.  Mom’s adding this stuff from Hawaii for you to see (Gideon, 5).


Friday’s Factoid Week 7

Our sky looks blue because our atmosphere scatters the blue light waves but Mercury doesn’t have any atmosphere so the sky is always just black even during the day when the sun is out. Also because there is no atmosphere it gets 800 degrees during the day and -290 degrees at night. Also my friend Benji got to see a SpaceX rocket launch and his mom took this picture (Sam, 9).

Mercury is the fastest planet in our solar system. It goes around the sun 4 times faster than the earth so a year on Mercury is 88 Earth days. But Mercury rotates really slow so a day on Mercury lasts for 59 Earth days. I wrote about Mercury on our blog when I was 7 but I don’t think I knew what I was talking about (Joel, 13).

Here’s that Friday Flashback Joel was talking about and another really yummy one just for fun!
