Friday’s Factoid 5 (by Titus and Joel)

We took a field trip up Mauna Kea. It is almost 14,000 feet high and has 12 giant telescopes on top. We got up in the middle of the night and drove to the top when it was still dark. We saw the glow of the lava from Kilauea Volcano. We saw the sunrise. It was more beautiful than a sunset and lasted for a long time. It was freezing cold even though we were in Hawaii (by Joel,7).

We ate donuts on Mauna Kea and then drove all the way down to the other side of the island. We went to the Planetarium at ‘Imiloa and learned about how the Hawaiians used the stars to find their way in their canoes. To get back to Hawaii they rowed toward the Southern Cross when it was 6 degrees in the sky. Then we went for a hike where there was a waterfall by the ocean and we had a picnic and climbed trees. There were parrots in the trees (by Titus,8).

An amazing but exhausting day. Sea level to 14,000 back down to sea level then all the way back around the Big Island (which really did seem big after all that driving). Have to share a few highlights for me. I’ve never seen the moon so bright or so close. We had to squint when looking at it like you would looking at the sun. Next was seeing the glow of lava inside the Kilauea crater thousands of feet below us and half an island away. Seeing and hearing the telescopes operating with their eyes to the sky was also pretty cool. The sunrise over the Pacific was spectacular. But the most memorable sight of the day was seeing the shadow of Mauna Kea cast by the rising sun out over the ocean. Totally surreal. Had to share a photo.

We are learning about the sun and tried to do some real science experiments but there has been lots of clouds and also Sam drank one of our control cups of water and spilled the egg we were cooking so those experiments didn’t work. We have a new pet duck and we got to burn one of his feathers with a magnifying glass. That was fun (by Joel,7).

We also learned about thermonuclear fusion which are little explosions inside the sun
that make it burn. The sun is getting brighter and hotter. If the sun was really billions of years old then a long time ago it would not have been able to burn a feather or cook an egg or make plants grow or keep us warm (by Titus,8).

So the solar science experiment kit I picked up at a garage sale was a bit of a disappointment. It was pretty chinsy to begin with but a series of cloudy days and an overly curious pre-schooler didn’t help. Just a heads up, I payed under a buck for the unopened kit but found the same thing on-line for $15-$25. Total rip-off. The same experiments can be performed with any-old thermometer, magnifying glass, and roll of tinfoil. Oh, and if you want to know more about the whole thermonuclear fusion thing and how it provides evidence for a young earth and solar system click on this article from ICR. 429

Friday’s Factoid 3 (by Titus and Joel)

This week we learned about the sun and other giant stars like Betelgeuse which is twice the size of the Earth’s orbit around the sun. But the biggest star they’ve found is the Big Dog star. Canis Majoris is 7 quadrillion times bigger then earth. Last night Mom woke me up and we went out by the ocean where we could see millions of stars. Jupiter was shining very bright and we saw 4 of the giant stars around it. We saw Betelgeuse, Rigel, Sirius and Aldebaran. This video shows how big some of the stars are. by Titus

All of these stars make noises but we can’t hear them because sound doesn’t travel in space. But God can hear them. You can listen, too, on this video. by Joel

How cool that our hymn this week mentioned the song of the stars!
“Forever singing as they shine, ‘The hand that made us is divine!”
I’ve added a new page to the top of the site called “Hooray for Hymns.” I’ve requested folks to add their own favorite hymns to the list we started by leaving a comment. Let’s join in the celestial chorus of praise to our Lord!
