Friction and Air Resistance
Students will explore friction and air resistance as forces that oppose motion, and investigate factors that affect their magnitude.
Key Questions
- Analyze how different surfaces affect the amount of friction generated.
- Explain the importance of friction in everyday activities.
- Design an experiment to investigate the effect of surface area on air resistance.
ACARA Content Descriptions
About This Topic
Found Sound and Foley Art encourages Year 7 students to see the entire world as a musical instrument. This topic focuses on sound design and the creation of atmospheric soundscapes using non-traditional sources, from crinkling paper to recording the hum of a refrigerator. This aligns with ACARA's emphasis on experimenting with sound and using technology to create and communicate musical ideas.
Students learn the art of Foley (creating sound effects for film) and how these sounds can tell a story without a single word or visual. This unit fosters a deep sense of 'active listening' to the environment. It is particularly engaging for students who may not have formal musical training, as it prioritizes creativity and observation over traditional theory. This topic comes alive through collaborative 'sound-story' challenges and hands-on recording missions.
Active Learning Ideas
Inquiry Circle: The Mystery Sound Box
Groups are given a box of random objects (keys, bubble wrap, a whisk). They must create a 'soundscape' for a specific setting, like a 'haunted kitchen' or a 'busy rainforest,' using only those objects.
Simulation Game: Foley Studio
Watch a 30-second silent clip of an action (e.g., someone walking through a forest). Students work in pairs to perform the 'live' sound effects in sync with the video using classroom objects.
Gallery Walk: Sound Map
Students record 10-second 'found sounds' around the school. They place a QR code of their sound on a map of the school. Classmates walk around, listen to the sounds, and try to guess the source and the 'musical' quality of each.
Watch Out for These Misconceptions
Common MisconceptionMusic only comes from 'real' instruments like pianos or guitars.
What to Teach Instead
Music is organized sound. Active exploration of 'found sounds' helps students realize that timbre (tone color) is a musical element that can be found in any vibrating object.
Common MisconceptionSound effects in movies are recorded 'on location.'
What to Teach Instead
Most sounds in films are added later by Foley artists. A 'Foley Studio' simulation quickly reveals to students how creative and 'fake' movie sounds actually are.

5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
unit plannerThematic Unit
Organize a multi-week unit around a central theme or essential question that cuts across topics, texts, and disciplines, helping students see connections and build deeper understanding.
rubricSingle-Point Rubric
Build a single-point rubric that defines only the "meets standard" level, leaving space for teachers to document what exceeded and what fell short. Simple to create, easy for students to understand.
More in Forces in Motion
Introduction to Forces
Students will define force as a push or pull, identify different types of forces, and understand how forces cause changes in motion.
3 methodologies
Gravity: The Universal Attractor
Students will investigate gravity as a non-contact force, exploring factors affecting its strength and its role in the solar system.
3 methodologies
Magnetic Forces and Fields
Students will investigate the properties of magnets, magnetic poles, and the concept of magnetic fields.
3 methodologies
Electromagnetism
Students will explore the relationship between electricity and magnetism, and construct simple electromagnets.
3 methodologies
Simple Machines: Levers and Pulleys
Students will investigate how levers and pulleys change the magnitude or direction of forces to make work easier.
