The London (that’s London, Ontario folks) District Catholic School Board has a website called Rich Performance Tasks, or RPT’s for short. The website is no longer updated, but the tasks are still there for others to access. They are real-life tasks that bridge different subjects. There are tasks for all grade levels and most subject areas within the Ontario curriculum. Each task has both a student and a teacher page. If you click on the teacher page, then you have access to pre-task activities, exemplars, and curriculum tie-ins.
If you click on the science tasks link, then you are brought to divisional science projects. There are tasks designed for primary, junior, and intermediate grades, and it appears that the goal was for students to work together across grade levels.
If you are only looking for science-based tasks, then I have some of my projects posted for all to use. Enjoy.
Note – This website is no longer accessible to the public…..sigh…..
