Grade 4 - Ontario Science Bundle - STEM Included - Updated 2026

Updated in 2026 - Grade 4 - Ontario Science Bundle - STEM Included - This product was created to cover the NEWLY UPDATED Ontario Science Grade 4 curriculum.

***Strand A: STEM/Coding has been added to this unit at no extra charge!

Most importantly, we have made cross-curriculum connections to the grade 4 language program. Students will practice reading comprehension strategies (making connections, questioning, visualizing, and inferencing) as they work through this unit.

Check out the preview of these units to learn more about how it can benefit your students. We know you will love this no-prep, just print, time-saving resource!
