## Activity Introduction

Quick summary: In this lesson, students will use their knowledge of forces, energy and the laws of motion to investigate an issue in society – the coward punch. They will learn about the coward punch in context, investigate the factors that affect the force of a punch, explain these using motion principles and perform calculations for forces and energy in a collision.

​​The STOP the Coward Punch education package aims to spread awareness about the devastating effects of the coward punch on our community. ​​This education package was developed by a team of experts, including a youth worker, education specialist and specialist teachers and references the latest research and laws on coward punches.

Learning intentions:

• Students will investigate what causes large forces in a punch
• Students will perform calculations involving forces, energy and Newton’s Second Law
• Students will understand that the motion resulting from a coward punch is sufficient to cause significant injury or death.

### Australian Curriculum Mapping

Content descriptions:

Year 10 Science:

• Energy conservation in a system can be explained by describing energy transfers and transformations (ACSSU190)
• The motion of objects can be described and predicted using the laws of physics (ACSSU229)

Syllabus outcomes: SC5-10PW, SC5-11PW

Relevant parts of Year 10 achievement standards:

Students explain the concept of energy conservation and represent energy transfer and transformation within systems. They apply relationships between force, mass and acceleration to predict changes in the motion of objects.

Topic: Social Issues

This lesson is part of the wider unit of work STOP the Coward Punch: Science – Years 9 & 10.

Time required: 60 mins.

Level of teacher scaffolding: Medium to High – teacher will moderate class discussions, run group activities and facilitate learning around a topic of violence which will require sensitivity and nuance.

Resources required:

• The Science Behind The Punch Article – one copy per student (digital or printed)
• Device capable of presenting video and images to the class
• Scientific calculators
• Student devices with internet capability (optional)
• Student Worksheets – one copy per student.

Teacher content information:

The STOP the Coward Punch campaign
STOP the Coward Punch by Danny Green aims to eliminate the coward punch from society and save lives in the process. Since 2000, over 172 Australians have been killed by a coward punch and many more were injured. The coward punch leaves a devastating ripple through society, mentally and physically scarring family, friends and survivor
