Reflection Questions
| Answers1. Our model needed two bones, which were two cardboard tubes. Our model needed three muscles, which was a tennis ball, and two metal strings. We were hoping that these muscles would work, but they did not. 2. Our tennis ball was similar to real muscle because it stopped the two bones from touching (Cartilage). Another way that it was similar to real muscles is that they both got the job done, making your elbow bend properly. Our actual model though did not do that. A difference was that our model looked so plain and dull. It was just a basic model of an elbow joint with nothing much really to it. Another difference was that you had to make your elbow move mechanically. You had to pull the strings up and down to bend it. 3. The model would not be able to bend properly. The model would bend to much. I am thinking of this just like a real life situation. You grab a rubber band that you found and play with it. Overtime the rubber band gets more stretched out and you can stretch it a lot more far back. 4. Ligaments are short bands of flexible tissue that holds together joints, bones, and cartilage. Tendons are strong tissues that connect a muscle to a bone. Cartilage is a material that keeps your bones from touching. 5. This activity was fun because you got to be creative and use tools to build a working product. This lesson was putting you to the test on your human body skills engineering skills, and how creative you are. 6. This activity was challenging because you had to work cooperatively with your partner. Many of the habits played a big part in this lesson like habit six, habit four, and habit two. In my opinion I thought it was really hard to work with a partner in this project. You feel like doing it your way but your partner has a good idea too and it is hard to let go of your ideas. |
