Butterflies begin their journey in a grade 7 classroom

These little critters may be smaller than a teacup, but they're about to embark on a journey across the continent.
It's migration time for Monarch butterflies.
And for some Ottawa students, that means letting go of their classroom pets.
Grade Seven students at Glen Cairn Public School have been raising nine Monarch butterflies since school began earlier this month.
Today, they're releasing them to the wild.  Shelley MacWhirter is the teacher in charge of the project.
