Innovation Day Science Project

My Innovation Day project is based on the Grade 4 science unit of Pulleys. We have learnt about fixed and moveable pulleys. I used a fixed pulley system for my project because it was on a sick so it was not a movable pulley.

For my hypothesis, I said: “I think it might work because of the total of four pulleys. Three big ones and one small one. The big pulleys connect to each other. They do that because when the stick gets pulled, it pulls the pulleys that pull the road up. The small pulley connects the stick to the big pulleys.”

This is a video for how to make a simple drawbridge:

Here are my results:

My conclusion is:                                                                                                                      My hypothesis was incorrect because I realised that the only way to connect the pulleys to the structure was to either hot glue it to one of the sides or to tape it. They both would have made it unable to spin/move/turn.

  1. As much as I like this specific post, since you did not due an “About Me” page [Hint, hint!], let me first ask the obvious question…what’s with the name? Should I know who Barny the Headless Chicken is from another source or is this an avatar all of your own making? I would love to know more…

    …as for THIS post in particular, I like the way you included both video and text to help us better understand your Innovation Day project. I also appreciate when people name their mistakes, so your hypothesis was incorrect, that’s where the learning comes from!

    Keep up the great work!
