No matter where we live, each and every one of us depends on transportation to some degree. Whether it's in our own personal cars or on public transportation shared with others, transportation is an important technology developed by engineers. Our focus in this unit will be on the Maglev train!
An engineer's job is never done. Testing and improving a Maglev is hard work. Fourth graders have to think about the dimensions of their train, how to keep their passengers safe, and how to carry more passengers if their train has done so safely. Transportation engineers must think about efficiency, so having more passengers moved safely from one place to another means they have reached their goal!
