Let's refer back to the Force and Motion Lesson Summaries page that you began using during the Force and Motion: Engage section.
How does the Grade 2–Force and Motion lesson build on the grade 1 and kindergarten lessons? How does it support the grade 3 and grade 4 lessons?
The kindergarten lesson focuses on magnetic and nonmagnetic materials. Grade 1 looks at how magnets push and pull. Grade 2 observes how magnets are used in everyday life. Grade 3 introduces gravity as a force, how to measure force using a spring scale, the concept of work, and simple machines. Grade 4 introduces the force of friction and how to design an experiment. Each grade level depends on the grade prior to lay the appropriate cognitive foundation. It is very important that we each do our part to help our students be successful.
