  1. One thing that I got wrong on the quiz was is a hockey stick a class one lever, class two lever, class three lever or is it not a lever at all? My answer was that it is a class 2 lever. The real answer was that it is a class 3 lever. I learned that a class 2 lever has the load in the middle.

  2. The question I got wrong was question 9 and the question was in second class a lever the effort force decreases as the load moves closer to the fulcrum and my answer was false but the answer was true. And one thing I learned was that a hockey stick is a third class lever. Chase

  3. I learned that a fulcrum can be anywhere and It does not have to be in the middle all the time and the question that I got wrong was the question with the"hockey stick" and I thought that it was not a lever at all and the real anwser was the hockey stick is a class three(3) lever.Katie

  4. The question I got wrong was the hockey stick one. I thought it was a class 2 lever but it was a class 3 lever instead. I learned that in all the class’ of levers the fulcrum moves to every side unlike the effort force and the load.

  6. When I took the Science test I got questions 5,8,11,12 and 13 wrong and I got questions 1-4,6,7,9 and 10 right. I learned that the farther from the fulcrum effort is, the less is required to lift the load.

  9. The question I got wrong was number 12. It said what kind of class lever is a crowbar? I thought it was a second class lever but it was a first class lever. Jason

  10. The question I got wrong was question 8 and I was surprised that my answer was incorrect. I never knew that a hockey stick was a class three lever I never even knew it was a lever until know.
