What are simple
machines? Where can they be found? Why are they important
to use? Why do we need them? These are
all very good questions that students may not always know the answers
to because they do not really think about using them. However, we
use simple machines of some kind daily.
machines are tools that make work and life easier for us, and they have
few or very little moving parts. Some of
the most commonly used simple machines include the following:
lever, inclined plane, wheel and axle, wedge, screw, and pulley.
These can be easily found at playgrounds, at school, or at home.
Students need to understand that some items that are made by using
simple machines include wheelbarrows, flag poles, wheelchair ramps, and
bicycles. These items are used every day of our lives without us
even thinking about them whether it is at work or at play.
