I found an amazing science nerd gem this month in LA.... it is the California Science Center...and it is free! (except for parking, unless you want to walk). It is part of Exposition park and there are some wonderful things to see down there. They have a natural history museum, a science museum, an air and space museum and a beautiful rose garden. We ran out of time and didn't get to the natural history museum, but the rest was fun.
This is an A-12 trainer that was originally used by the CIA and then taken over by the military. It is one of the fastest planes and can reach speeds twice the speed of sound. They also used this design to make a slightly smaller, slower plane- the SR-71 that was more commonly used by our military for survallience.
I just loved this model of DNA and it is great that both my kids knew what it was.
The science center has an ecosystem section that has a bunch of rooms devoted to different ecosystems. This was the islands room and the contraption that Eli is playing with has to do with adaptations and how organisms, such as birds, change to fit their environments. The sticks had different shaped "beaks" and they had to see what food types they were better suited for. I used to do a slightly smaller scale version of this in my high school classes so I got to teach my kids the reason why they were trying to capture different objects with strange sticks.

This was in the poles room and that is a wall of ice. There were different materials in those mitts (feathers, cotton, fur, fat, etc.) so that the kids could figure out which material would be the best insulator. This also ties in with adaptations because it helps them see how animals have been able to survive in such a cold climate. (Side note- I learned something neat about a larva fish- since it lives in such cold water it doesn't have any red blood cells because they would slow down due to cold and clog up so instead it absorbs oxygen right through it's skin and gills so it doesn't need the blood to carry it. Aren't adaptations fun!)- Sorry that was a run away nerd moment!
For lunch we had brought a picnic, I though it would be nice to eat out in the rose garden.
That pretty building in the back is the natural history museum.
I just thought that these leaves were so cool.
We ate lunch in a gazebo and then walked around a little. There was a family that decided to play hide and seek with their kids, until they realized that they couldn't find their son, not the smartest idea, we are still in LA people!
After that it was off to the air and space museum. This was one of my kids favorite things. But what little boys don't love big planes!?!
This was very neat, it is an Apollo capsule from a mission that linked up with the Russian Soyez. I have to admit that I was a little teary eyed as I was describing it to the kids because it is the same design (except for the modified door mechanism) as the Apollo one capsule that had a fire during a training and all three men inside died. The men who tried to save them ran to open the hatch but couldn't get it open and watched through the small window as their friends perished. So sad!
This was a Gemini capsule. The Gemini project was to prepare for the Apollo missions. Gemini means twins which was fitting because two men would go up instead of the one in the Mercury flights previous to the Gemini program. I don't know if you can see it well but there are two seats and the men had to squeeze in there together.
After that we went back over to the science center and went through the kelp forest ecosystem. This was my favorite because it reminded me a lot of Sea World.
This was a small, and very cold, tide pool. The anemone that Donald is touching is an Anthopleura xanthegramica (woo- there are some things I still remember from college), there were also some sea urchins (Strogliocentrotus Purpuratus) and some keyhole limpets, sea stars and hermit crabs. I wish I had gotten more pictures, but my hands were wet and the center was closing in about 10 minutes so we were kind of rushed. As we left we went past the moon jelly tank and I said "Oh, look Eli, moon jellies." He said, "What are they?" So I said, "They are a type of Jelly Fish." And he replied, "You mean Sea Jelly, they are not fish!" I have taught him too well. Love my science nerds!
