Step Three - Engineering

How everyday items work

This year for the curious minds imitative 3rd class investigated and developed an understanding of how everyday items work.

We focused on the six simple mechanisms

The class learned that:

Mechanisms are designed to perform many functions to make our lives easier. This is called MECHANICAL ADVANTAGE.

We also learned that:

To get an object to move, you need to push it or pull it.

• A push or pull is called a force. The force makes the object move over a distance.

 • Force and distance are the two important things that are changed by a mechanism.

In groups the class researched and carried out project work on each of the six simple mechanisms which included

  1. Leavers 2. Wheels and axels 3. Pulleys 4. The inclined Plane 5. Wedges 6. Screws

Everyone had great fun and learned so much about Simple mechanisms. Well done Everyone!
