Experimenting With Levers and Pulleys by Daphne and Ellie M.

Using a kit with levers and pulleys we decided to experiment and created some simple machines from the instructions booklet. We made a see-saw (lever), a pair of scissors (lever), a flagpole (pulley) and a balance scale (lever).  The see-saw and scale reminded us of the ‘lift the teacher challenge’ because you could lift a heavier load using a lighter load by positioning the heavy load closer to the fulcrum! Here is a video of the machines we made:

  1. Dear Daphne and Ellie M.,
    I really like the video that you have made.
    Also, I really like how you actually built a type of
    pulley and a type of lever and it was very well built.

  2. Dear Daphne and Ellie,
    I loved your ideas. I think I will try some of them at home.
    You are very creative.

    1. Dear Nethmi and Penny,
      Thanks for commenting! If you want to build them at home I think you can use other materials (lego maybe) or by combining parts from different kits. I am glad you liked our video and simple machines!

    1. Dear Marialena,
      Thanks for commenting! I also liked the scissors a lot too! 🙂 The kit we used is a K’NEX Levers and Pulleys kit. Ms. Maratou has asked me to bring it in so you will see it this week!
