2022 Curriculum - Grade 4 - Machines & Mechanisms - Ontario Science STEM

UPDATED IN 2022! BOTH GOOGLE SLIDES AND PDF VERSIONS INCLUDED!

New Ontario 2022 Science Curriculum - Grade 4 – Machines and Their Mechanisms. This product was created to cover the NEW 2022 Ontario Science Grade 4 curriculum – Machines and Their Mechanisms.

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

There are 134 activity sheets that cover the expectations in the new science curriculum. This massive unit contains readings, diagrams, experiments, true/false, and much more!

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 this unit to learn more about how it can benefit your students. We know you will love this no-prep, just print, time-saving resource!
