We woke up late, again, but early enough to catch the last fifteen minutes of the free breakfast provided by our hotel, the Days Inn. We ate waffles, cereal, toast, and drank orange juice. This was our second day in Omaha and we headed back to the Aquazone to by a few more Olympic Trial shirts for friends. We also managed to get one more autograph from Kaitlyn Sandeno, a gold medalist, and a former world record holder.
Once we’d finished all our shopping, we drove to the Bob Kerrey Pedestrian Bridge. The bridge stretches across the Missouri river, and you can stand on it, with one foot in Iowa and one foot in Nebraska at the same time.
We also saw the Louis and Clark museum. Next, we drove to Souix City, Iowa. We visited another Louis and Clark museum. This museum was larger, and had a interactive exhibit. It had talking, human-like robots, acting out Lewis, Clark, President Jefferson, and other important people.
After browsing the museum, we drove back to Omaha, watching acres and acres of green corn sway. When we finally got to the hotel, we ate Subway, and fell asleep.
The Muscular System is made up of muscles. There are two main types of muscles, voluntary muscles, and involuntarily muscles. There are also Skeletal muscles, Smooth muscles, and Cardiac muscles. Smooth Muscles are like the muscled that line the inside of your stomach. Cardiac and Smooth muscles are involuntary. Involuntary means that do things without you having to think about it. Voluntary means you need to think about it to do it. Skeletal Muscles are voluntary because you think before you move and your brain has to tell your muscles to move. Bones and muscles have to work together to allow you to move.
The skeletal system is made out of our bones and our cartilage. Cartilage is tissue that’s flexible, like the cartilage in our noses. Some main type of bones are ribs, femurs, pelvis, and fibula. The place where two or more bones meet are called joints. Some types of joints are pivot joints, gliding joints, hinge joints and ball-and-socket joints. Your knee is a ball-and-socket joint. A pivot joint, for example, is found in the neck. If we didn’t have bones, we would be a lump of cartilage, skin, and organs. Bones are what make up our structure and shape. Our bones also allow us to move. If we didn’t have bones, we would have to stay still our whole lives! That would be pretty boring! They also protect some of your organs.Your ribs, for example, protects your lungs and heart. Strings of tissues that hold our bones together are called ligaments. Ligaments also help to keep us moving.
