Contact Forces in Action
Students will investigate forces that require direct physical contact, such as pushes, pulls, and friction.
Key Questions
- Explain how a door opens when you push it.
- Compare the force needed to pull a toy car versus pushing it.
- Design an experiment to measure the force required to move different objects.
ACARA Content Descriptions
About This Topic
Energy and Dynamics explores the 'how' of movement, the quality and weight behind every step and gesture. In Year 3, students investigate the contrast between sharp, percussive movements (like a robot or a lightning bolt) and smooth, fluid motions (like water or a drifting cloud). This topic aligns with ACARA's dance standards, which require students to explore and use dynamics to express ideas and moods.
Students learn that the same movement can mean something completely different depending on the energy used. A 'sharp' reach might look like a grab, while a 'fluid' reach might look like a greeting. This topic encourages students to become more mindful of their physical control and to use dynamics as a tool for storytelling and emotional expression.
Active Learning Ideas
Simulation Game: The Energy Machine
The class forms a 'machine' where each student adds a movement. The teacher acts as the 'operator,' calling out different dynamics (e.g., 'Smooth and oily!' or 'Sharp and electric!'). Students must instantly change the energy of their movement while keeping the same shape.
Inquiry Circle: Dynamic Duets
In pairs, students create a four-count movement sequence. They must perform it twice: once with 'heavy, strong' energy and once with 'light, airy' energy. They then ask another pair to describe the 'story' or 'character' they saw in each version.
Think-Pair-Share: Nature's Dynamics
Students think of an animal that moves sharply (like a crab) and one that moves smoothly (like a jellyfish). They share their movements with a partner and discuss what kind of music would fit each animal's 'energy.'
Watch Out for These Misconceptions
Common MisconceptionDynamics just means moving fast or slow.
What to Teach Instead
Students often confuse speed (tempo) with energy (dynamics). You can move slowly but with 'sharp' energy (like a slow-motion robot). Active exercises that separate speed from weight help students understand this subtle but important difference.
Common MisconceptionStrong movements have to be loud.
What to Teach Instead
Students often stomp when they want to show 'strong' energy. Through peer observation, they can learn that 'strength' in dance comes from muscle tension and control, which can be completely silent, making the movement even more powerful.

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.
More in Pushing and Pulling
Introduction to Forces
Students will identify and describe various pushes and pulls encountered in everyday life.
2 methodologies
Gravity: The Invisible Pull
Students will explore gravity as a non-contact force that pulls objects towards the Earth.
2 methodologies
Magnetic Forces
Students will investigate magnetic forces as another type of non-contact force, observing attraction and repulsion.
2 methodologies
Friction: Opposing Motion
Students will investigate how friction acts as a force that opposes motion between surfaces.
2 methodologies
Reducing and Increasing Friction
Students will explore methods to either reduce friction (e.g., lubrication, smooth surfaces) or increase it (e.g., rough surfaces, treads).
