Balanced and unbalanced forces introduce Grade 3 students to an essential idea in physical science: how forces affect the motion of objects. This science mini book set focuses on the relationship between balanced forces, unbalanced forces, and changes in motion, giving teachers a topic-specific resource for introducing forces and motion in the elementary classroom.

Exploring Balanced and Unbalanced Forces

Students encounter the key distinction between balanced and unbalanced forces and explore how these forces relate to the movement of objects. The topic provides an opportunity to develop foundational science vocabulary and begin explaining why an object may remain in the same state of motion or experience a change in motion when forces act on it.

Rather than treating forces as an abstract science term, the resource centres instruction on the two main types of forces named in the title. This makes it relevant when introducing a Grade 3 forces and motion unit or reinforcing an elementary science lesson about how pushes and pulls affect objects.

What Students Explore

• Balanced forces: Introduce the concept of forces that balance one another.
• Unbalanced forces: Explore forces that do not balance and their relationship to changes in motion.
• Forces and motion: Build foundational knowledge of how forces influence the movement of objects.
• Science vocabulary: Become familiar with the central terms needed to discuss balanced and unbalanced forces.

A Mini Book Format for Science Lessons

The mini book format offers a focused way to bring this physical science topic into a Grade 3 lesson. Teachers can use the set when introducing balanced and unbalanced forces, reinforcing a classroom discussion, or providing a topic-specific printable for students to revisit during a forces and motion unit.

It can also serve as a resource for independent classroom learning, science review, or additional practice when students are developing their understanding of how forces affect objects. Its focused subject matter makes it easier to incorporate into an existing elementary science sequence without introducing unrelated topics.

Curriculum Reference

The supplied curriculum reference identifies the Next Generation Science Standards (NGSS), 2013, performance expectation 3-PS2-1. This standard focuses on planning and conducting investigations to provide evidence of the effects of balanced and unbalanced forces on the motion of an object. Teachers should review the actual resource content when determining its suitability for their specific lesson objectives.

Bring balanced and unbalanced forces into your Grade 3 physical science lessons with a focused mini book resource centred on one of the foundational concepts in forces and motion.
