Introduction to Biological Classification
Students will explore the historical development and importance of classifying living organisms.
Key Questions
- Analyze the historical reasons for developing classification systems.
- Evaluate the benefits of a universal naming system for species.
- Differentiate between common names and scientific names for organisms.

About This Topic
This topic introduces Year 7 students to the foundational elements of visual language: line and texture. In the Australian Curriculum, students explore how mark-making is not just a technical skill but a primary tool for expression and communication. By experimenting with different line weights, directions, and qualities, students learn to convey weight, movement, and emotional states. This unit also emphasizes the tactile nature of art, encouraging students to observe and replicate textures from their local environment, including natural patterns found in the Australian landscape.
Understanding these elements is essential for developing visual literacy and a personal artistic voice. Students begin to see that a jagged line feels different from a fluid one, and a rough texture evokes a different response than a smooth surface. This topic comes alive when students can physically experiment with various drawing tools and participate in collaborative critiques to see how their peers interpret different marks.
Active Learning Ideas
Stations Rotation: The Texture Lab
Set up four stations with different mediums like charcoal, graphite, ink, and wax crayons. At each station, students must replicate a specific natural texture found in the schoolyard, such as eucalyptus bark or sandstone, focusing on how different tools change the tactile feel of the drawing.
Think-Pair-Share: Emotional Lines
Provide students with a list of emotions like 'anxiety,' 'calm,' or 'energy.' Students draw a single line representing each emotion individually, then pair up to compare their marks and discuss why certain line weights or shapes feel more 'anxious' or 'calm' than others.
Gallery Walk: Mark-Making Mystery
Students create a non-objective drawing using only line and texture to describe a secret object. Classmates move around the room with sticky notes, writing down the physical qualities they perceive (e.g., 'sharp,' 'fuzzy,' 'heavy') based solely on the visual evidence.
Watch Out for These Misconceptions
Common MisconceptionTexture is only something you can feel with your hands.
What to Teach Instead
In visual arts, we distinguish between tactile texture and visual (implied) texture. Active drawing exercises help students realize they can use 2D marks to trick the eye into seeing a 3D surface.
Common MisconceptionA 'good' line must be perfectly straight or smooth.
What to Teach Instead
Students often strive for mechanical perfection, but expressive art relies on varied line quality. Peer observation sessions help students see that 'broken' or 'sketchy' lines often carry more character and energy.

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.
