Properties of Sound: Reflection, Refraction, Diffraction
Investigating how sound waves interact with their environment, leading to phenomena like echoes.
Key Questions
- Explain what causes the 'echo' effect when sound hits a distant wall.
- Analyze how sound waves refract when passing through different mediums.
- Compare the reflection and absorption of sound by various materials.
ACARA Content Descriptions
About This Topic
Interactive Storytelling moves beyond the linear 'beginning, middle, end' to explore narratives where the audience has agency. In Year 9, students design non-linear experiences for games, apps, or interactive films. This topic aligns with ACARA's focus on using digital technologies to create complex, multi-layered media artworks.
Students learn to create 'branching narratives' where user choices lead to different outcomes. This requires a high level of logical thinking and empathy, as students must anticipate how an audience might react. This topic is best taught through collaborative problem-solving and 'paper prototyping', where students map out their stories physically before moving to digital tools, ensuring the narrative logic is sound through peer testing.
Active Learning Ideas
Inquiry Circle: Branching Maps
Using large sheets of paper and sticky notes, groups map out a 'Choose Your Own Adventure' story. They must ensure every choice leads to a logical conclusion and that there are no 'dead ends' in their narrative.
Simulation Game: The User Test
Students act as 'players' for another group's paper prototype. They make choices and the 'creators' must manually move them through the story, noting where the player got confused or where the story felt most engaging.
Think-Pair-Share: The Ethics of Choice
Students discuss a game where they had to make a 'moral' choice. They share with a partner how that choice made them feel more (or less) connected to the story compared to a movie where they have no control.
Watch Out for These Misconceptions
Common MisconceptionInteractive storytelling is just for video games.
What to Teach Instead
It is used in marketing, education, and interactive documentaries. Active workshops on 'branching paths' show students how these techniques apply to many digital platforms.
Common MisconceptionYou need to be a coder to make an interactive story.
What to Teach Instead
The core of the work is the narrative design. Tools like Twine or even hyperlinked Google Slides allow students to focus on the 'story' rather than the 'code'.

Planning templates for Science
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.
