Bays Mountain Planetarium

Bays Mountain Planetarium
By Keegan

Our co-op visited Bays Mountain Planetarium. The planetarium had just been redone so it looked beautiful. It had a better stargazer and better 3-D abilities. We watched a program called Connections. We were on Pegasus' back and we went through the galaxies. One part we went through our own Milky Way galaxy and saw lots of planets. The program pointed out some of the constellations like Orion's Belt, The Drinking Gourd, Pegasus, and The Big Bear.

Natural History Museum- Gray Fossil Site

Gray Fossil Site
By Keegan, McKenna and Braden

We went to the Gray Fossil Site with our co-op. This site was found when the road workers were digging to widen a road. They found bones from the Micene period. They stopped building the road and scientists from ETSU have been digging for bones ever since. Some of the fossils they have found are: alligators, red pandas, lizards, snakes, short faced bears, camels, shovel tusked elephants, saber toothed cat, rhinos, and tapirs (see picture). This site has the most tapir fossils (over 50) in the world.




First we watched a movie about the digging. Then we toured the museum and saw many of the bones and animals that had been found. Then we went outside and saw the actual dig sites. There were men there actually digging for the rest of a shovel tusked elephant. Then we went to the rhino pit and we saw a bunch of limestone rock. Then we went to a tent and we started to look for bones ourselves! One of the boys in our co-op found some type of bone.

Hands on Museum

We went to the Hands on Museum and dissected a squid. Rayanna was my partner. First we needed to look at the outside of the squid and study it. It had spots called chromatophores. They are different sizes so that it can camouflage itself. Then we cut inside the squid. We learned that a squid has three hearts. The squid has two tentacles, the rest are arms. The squid has a beak inside of its mouth. The squid even has ink inside of its body. We burst the ink sack and tried to write our name with it. It was not very easy to write with squid ink. It has a pen-like thing inside to hold the shape of its body. Have you ever seen a squid before? If you have, have you noticed that it doesn't swim smoothly but instead it swims in spurts? Well, the thing that helps the squid move like that is called a siphon.

The purplish color is the ink after the sack was burst. The blue and pink is artificial dye injected into the squid to help one study the veins and arteries.


My favorite part of the squid was the chromatophores. They are little dots on the bottom of the squid and are all different sizes. They camauflage the squid. The mouth is very cool. It is under the tentacles on the top. My partner was Mitchell. The gills looked like leaves on the side of the squid. The gills are used for breathing. A squid has a beak. It is in a little ball down its throat. We split the ball and the beak looked a little like a bird's beak. We got a toothpick and busted the squid's ink pouch. We used the ink to write our name. Our squid was a male. Almost everyones was a male, but there were a couple of females. The females have a fluffy mass inside their body that males do not have.

There were 20 kids participating in the squid dissection.



We went to the Hands On Museum, and I got to learn about about Madagascar Hissing Cockroaches. I got to pet the cockroach. The cockroaches live in Madagascar. They are called Hissing Cockroaches because they hiss at you. But when I held it, it did not hiss at me. It did not hiss at anybody. They are bigger than other cockroaches. Look at the picture below these words. When the lady put her hand out with the roach, she turned it upside down. The roach did not fall off because there is a sticky pad and claws on the roach. The lady told us that it kind of tickles, but it does not hurt when she holds the roach upside down and it sticks on.
By Braden



There were about 15 kids participating in this program while the other kids dissected the squid.




The Hands on Museum has a grocery store that is fun to play in. In the picture below, I am buying everything in the store. There is a cash register that gives fake money out. Ronnie showed me how to get the money out of the cash register.
