Reflection#4 July 12, 2012:

A) Bridge Support for Textbook?  What worked?  What did not work?  Why?



 B) Wave Quest:  What surprised you?  What do you want to know more about waves?

  1. A) While the toothpicks (and reinforcing supports by using two toothpicks per bar) worked well, the marshmallows simply were not a powerful enough adhesive. Therefore, when the book came down, no matter how wide the structure, the middle would have been ripped into like a stack of loosely-placed Jenga blocks.

    B) What suprised me most about waves was the fact that, among other things, rogue waves are well-documented in a scientific manner. Any previous news I had heard about them depicted them as a mysterious phenomenon, akin almost to the Bermuda Triangle legends. However, scientific attempts to study them were documented in said television program. Perhaps tales of rogue waves were exaggerated for the sake of drama, which increases viewer ratings.

  2. A) The marshmallows did not work in the construction of the bridge because it was not hard enough or sticky enough to sustain the textbook.
    B) I was suprised that the ocean and water played a big part on the Earth's climate. I would like to know more about velocity and inertia.

  3. A)None of the bridges supported the book. We thought interconnected triangles would support it , but other variables such as the hardness of the marshmallows,thickness of the toothpicks, and weight of the book made the experiment fail.
    B) It suprised me that our structure didn't work because we learned in school that triangles or trusses provide the most stability in a bridge. Also, that the stickness of the adhesive would have affected the structure. I would like to learn more about sound waves because I am interested in music, and I think it would be fascinating.

  4. A)Nothing worked when trying to support the textbook. Nothing went right but everything went wrong. It didn't worked because the marshmallows were too soft and could not handle the pressure of the book. If the marshmallows were harder or tougher then there is a high possibility that this experiment would have worked.

    B)It surprised me that Ms. Cooper wanted my class to make a bridge to support a textbook out of marshmallows and toothpicks. I would like to learn more about tsunami formation and more about tsunamis in general.

  5. I found the bridge activity today very exciting since I enjoy the idea of building structures. Due to the fact that the marshmallows were significantly weak adhesives for the toothpicks to be sturdy, all the bridges were unable to hold up the textbook. If we had stronger materials as well as more time, I believe at least one of the groups could have been able build a standing structure.
    Finding out about what makes a tsunami a special type of wave was quite interesting. I would like to find out about the different factors that affect the traveling of a wave.

  6. A) The activity worked onin class today was very exciting because it required group and team work. Although none of the bridges were able to hold up the LARGE textbook, it was till quite fun playing around with squishy marshmellows that were quite weak. What could've made the bridges sturdy was using Dots or gum drops.
    B)What surprised me was that Ms. Cooper wanted us to create a bridge out of marshmellows because it was very weak. I want to know more about the structure of bridges.

  7. The toothpicks were fine. If we had a stronger adhesive then the bridge would've worked. I didn't know what a rouge wave was. I want to continue learning about them.

  8. The building bridge activity was very fun. The toothpicks had worked, however due to the fact that the marshmellows weren't hardened, the marshmellow base didn't work. They were just not stable enough to hold the weight of the book.
    I didn't know that ocean waves were created by wind and that slightly suprised me. I want to know how do swells survive such a long way if they travel very far distance from the point of origin.

  9. The bridge support competition was very entertaining and yummy. Although the marshmallows were soft, it was easy to see which supports would have worked and which ones needed a little bit more reinforcement. The groups that made complex structures that were interconnected would probably have won the challenge if they had more sturdier materials. They were layered on each level so there was support on each level. The structures that were made up of separate supports would not have worked as well because there wasn't enough of them to support the book.
    I was surprised at the creativity that was in the room because all of the groups were under pressure and very stressed out. I would like to learn more about the actual movements that occur in a wave and the and the person that understood waves first.

  10. The activity was fun but it wasn't successful. the marshmallow were weak which made the foundation of the bridge not strong enough and the weight of the book crashed every ones bridge. what surprised me about wave is the fact that it has a great impact on earth i didn't know that until we went through wave in class. i will love to learn more about wave.

  11. I was surprised that tsunamis were not caused by wind. I want to know how sea life are affected by waves.
