We took part in a Bricks4Kidz workshop. Each girl in the class made a scissors lift using lego and a motor.
We learned that:
* A scissor lift makes it easier to lift things in a factory, and also offers a larger work platform than a ladder can provide.
* It is called a scissor lift because the crisscross arms that raise and lower the work platform look like scissor blades.
* Scissors as well as a scissor lifts are both examples of a simple machine called a lever. The place where the arms meet is called the fulcrum.
* The force changes from horizontal to vertical at the fulcrum.
As you can see from the pictures, we really enjoyed ourselves.
