Chalmers Street P.S. is celebrating Earth Day!  Wednesday April 22 is Earth Day, and students will be taking part in many Earth-friendly activities throughout the week.  Primary and Junior classes have signed up for a school-yard clean-up, and many students are enjoying environment-centred learning in the classroom!  Chalmers has also joined with other schools in Waterloo Region for Spring Walk To School Day.  More details to come!
