Oz-e-Science: Physics Year 2 V2

Physics Year 2 is the study of what things are made of, how they move and how they get energy. It aligns to the Australian Curriculum Science Understanding: 

• ‘Explore different actions to make sounds and how to make a variety of sounds, and recognise that sound energy causes objects to vibrate (AC9S2U02)’ 

Success Criteria

• Explain how force applied to materials creates sound. 
• Show how force on materials makes sound. 
• Explain how movement (kinetic energy) converts into sound energy. 
• Observe how movement (kinetic energy) converts into sound energy. 
• Describe how different materials vibrate to produce sound. 
• Observe how different materials vibrate to produce sound. 
• Describe how sound waves travel through different mediums. 
• Investigate how sound waves travel through solids. 
• Explain that humans sense sound through hearing and feeling. 
• Investigate sensing sound through hearing and touch. 
• Explain sound intensity and its measurement. 
• Investigate sound intensity and its measurement. 
• Explain the difference between noise and music. 
• Identify pitch variations. 
• Explain how sound is sometimes absorbed or reflected. 
• Explain how sound is sometimes absorbed or reflected. 
• Recall what we have learned about sound in this Unit. 

Learning objectives

In lessons 1 to 10, students learn about:  

1.  how force applied to materials creates sound. 

2.  how movement (kinetic energy) converts into sound energy. 

3.  that vibrations of materials create sound waves. 

4.  how sound waves travel through different mediums. 

5.  how we sense sound through hearing and feeling. 

6.  sound intensity and its measurement. 

7.  the sound of music. 

8.  how sound is sometimes absorbed and sometimes reflected by certain materials. 

9.  the speed of sound. 

Assessment

End-of-Unit Assessment 
The last lesson is the End-of-Unit Assessment which has a variety of question formats (e.g., label the diagram, circle the correct answer) to assess student mastery of content from the unit.  
The End-of-Unit Assessment is in the Teaching Guide. Teachers copy the assessment and distribute to students at testing time.
