Overview

Grade 3 Science Forces and Motion is an Ontario print-only lesson bundle designed for classroom-ready instruction, with 8 worksheets and PDF answer keys with rubric for quick grading and targeted feedback.

This unit brings students from measuring and comparing motion to predicting movement using forces, slopes, gravity components, friction, and net force. Across the set, students practice using evidence from observations and data, explain cause-and-effect relationships, and build confidence applying their ideas to new situations.

Use the included materials to support a standards-aligned unit in a way that’s easy to plan, ready to print, and straightforward to assess.

What's Included

• ✅ Comparing Speed Using Distance Over Time Grade 3 Science Worksheet Ontario – Students compare speeds by interpreting distance-over-time relationships and reasoning about which object moves faster.
• ✅ Grade 3 Predicting Motion From Forces and Slopes Science Worksheet Ontario – Students predict motion outcomes by connecting pushes/pulls and slope conditions to expected movement.
• ✅ Grade 3 Measuring Distance and Speed Worksheet | Ontario Science Activity – Students practice measuring distance and calculating speed to support evidence-based claims.
• ✅ Grade 3 Inclined Motion and Gravity Components Science Worksheet Ontario – Students analyze how gravity contributes to motion on inclines and use that evidence for explanations.
• ✅ Grade 3 Friction and Resistive Forces Worksheet | Ontario Science Activity – Students identify how friction and resistive forces change motion and direction, then justify their reasoning.
• ✅ Grade 3 Forces as Pushes and Pulls Worksheet | Ontario Science Activity – Students classify forces as pushes or pulls and connect force direction to observable changes in motion.
• ✅ Grade 3 Net Forces and Directional Motion Science Worksheet Ontario – Students determine how net forces influence direction and movement, using patterns in the data.
• ✅ Net Influence and Motion Worksheet Grade 3 Science Ontario Activity Pack – Students synthesize the unit concepts to explain net influence on motion in new, practical scenarios.

Skills & Standards

Within the Ontario framework, this Grade 3 Science Forces and Motion unit supports core ideas about forces as causes of change in motion. Students strengthen crosscutting concepts such as cause and effect (how forces lead to changes in speed or direction) and systems and interactions (how slope conditions, gravity components, friction, and resistive forces work together).

Students also build modeling and analytical reasoning by interpreting measurement information (distance and time), using relationships to compare speeds, and applying those patterns to predict outcomes. Each worksheet emphasizes evidence-based explanations: students move from observation to claim, then back to supporting details from the provided situation.

Aligned to {standards}, the set develops skills in force identification (push vs. pull), recognizing how different forces affect motion, and determining how net force influences directional movement and overall “net influence” on an object.

Perfect For

• Teachers seeking structured instruction
• Sub plans
• Homework or review
• Intervention or centers
• Assessment preparation

How to Use

Plan for a typical 1–3 week sequence that follows a clear progression: start with measuring and comparing speed, move into predicting motion using forces and slopes, and then deepen understanding through inclined motion, friction/resistive forces, and net forces leading to directional motion. The final worksheet supports end-of-unit synthesis of net influence on motion.

Try these classroom routines: (1) begin each day with a 5-minute warm-up that revisits one key idea (speed, slope prediction, or friction effects) using a question from the set; (2) use guided practice during the middle worksheets to model how to turn observations into explanations of force-driven motion; (3) administer exit tickets after the net force and synthesis pages so students can demonstrate application ability and build confidence with targeted feedback using the provided rubric.
