Explore forces and motion in Grade 7 Science through five real-world investigations that challenge students to identify forces, determine net force, and explain how objects move. Focusing on Motion and Stability: Forces and Interactions, this learning stations resource connects the relationship between force, mass, and acceleration to everyday motion.

Investigate How Forces Change Motion

Students examine the forces acting on objects and determine the direction of the net force. They explore how balanced and unbalanced forces affect motion, with particular attention to how unbalanced forces change an object's speed or direction. The activities also develop an understanding of how an object's mass and the net force acting on it relate to acceleration.

Rather than treating force and motion as isolated vocabulary terms, the investigations encourage students to apply these physical science concepts to real-world situations and explain why objects move the way they do.

What Students Work On

• Identify the different forces acting on an object.
• Determine the direction of the net force.
• Explain how unbalanced forces affect an object's speed and direction.
• Use the relationship between net force, mass, and acceleration to explain motion.
• Record investigation information and reflect on learning through a station wrap-up.

What's Included in the Download

• Five station cards presenting the real-world investigations.
• A station recording sheet for documenting student work.
• A station wrap-up for reviewing the investigation experience.
• An answer key PDF with a dedicated teacher guide.

The included teacher guide contains Learning Objectives, Teaching Tips, Discussion Questions, and Common Mistakes. This gives teachers additional support for preparing the activities, guiding classroom conversations, and addressing misconceptions about forces and motion.

Practical Classroom Uses

Organise the five station cards into a learning stations lesson for your Grade 7 physical science class. Students can work through the investigations, use the recording sheet to document their thinking, and complete the station wrap-up to revisit the main ideas. The teacher guide and answer key PDF provide useful reference material when preparing instruction and reviewing student responses.

This resource also offers a focused option for reinforcing net force and acceleration during a unit on forces and interactions. It can support classroom practice, lesson activities, and review of how force and mass influence changes in motion.

Curriculum Connection

Designed for Grade 7 Science, this resource is identified with the Next Generation Science Standards (NGSS), MS-PS2-2. Its focus on forces, interactions, net force, and changes in motion makes it relevant to middle school physical science instruction.

Give students opportunities to investigate forces in context, explain changes in motion, and connect net force, mass, and acceleration through practical classroom learning.
