Forces and Friction · Term 2

Friction: Resistance to Motion

Students will investigate how friction acts as a force opposing motion, exploring factors that influence its strength.

Key Questions

  1. Explain how different surfaces create varying amounts of friction.
  2. Analyze the role of friction in everyday activities like walking or braking a bicycle.
  3. Design a solution to either increase or decrease friction for a specific purpose.

About This Topic

Choreographing Narrative focuses on the art of making dances that tell a story or express a specific theme. In Year 4, students learn how to arrange movements into a logical sequence with a beginning, middle, and end. This topic aligns with ACARA's focus on composition, where students use the elements of dance to create original works. They explore 'choreographic devices' like repetition, contrast, and transitions to guide the audience through their narrative, whether it's a story about a bushfire, a playground friendship, or a journey across the sea.

Choreography is a collaborative problem-solving task. This topic comes alive when students can work in small groups to 'draft' and 'edit' their movements. By seeing their ideas performed and receiving peer feedback, students learn that choreography is a process of making choices, testing them, and refining them to better communicate their message.

Active Learning Ideas

Watch Out for These Misconceptions

Common MisconceptionA dance story has to be literal (like a play).

What to Teach Instead

Dance stories are often 'abstract' or 'thematic'. Active learning exercises that focus on 'emotions' (like 'fear' or 'excitement') rather than 'plots' help students understand that dance communicates through feeling.

Common MisconceptionYou need music to start choreographing.

What to Teach Instead

Some of the best choreography starts in silence to focus on the movement itself. Teaching students to 'dance the rhythm of the story' first helps them create more original movements that aren't just following a beat.

Frequently Asked Questions

What is a 'motif' in dance?
A motif is a short, distinctive sequence of movement that becomes a recurring theme in a dance. It's like a 'visual word' that the choreographer uses to represent an idea or a character.
How do I help students who 'get stuck' when making up moves?
Give them constraints! Tell them they can only move on the floor, or they must always keep one hand on their head. Active learning thrives on 'creative limitations' which force students to think outside their usual habits.
How can I assess choreography fairly?
Look for the 'intent'. Did the student use the elements of dance to show the theme they chose? Use a simple rubric that focuses on 'use of space', 'clarity of movement', and 'collaboration' rather than technical skill.
How can active learning help students understand choreography?
Active learning, such as the 'Motif Exchange', teaches students that choreography is a form of communication. When they have to teach their move to someone else, they have to be clear about the 'shape' and 'energy' of that move. This peer-to-peer interaction reinforces their understanding of dance as a structured language, not just random movement.
