Using Dichotomous Keys
Students will practice creating and using dichotomous keys to identify unknown organisms based on observable characteristics.
Key Questions
- Design an effective dichotomous key for a small group of objects or organisms.
- Evaluate the efficiency and accuracy of different dichotomous keys.
- Analyze how a single ambiguous characteristic could invalidate a dichotomous key.
ACARA Content Descriptions
About This Topic
Symbolism in still life allows students to bridge the gap between the physical world and abstract ideas. In this topic, Year 7 students investigate how everyday objects can carry deep cultural, personal, or historical meanings. This connects to the ACARA focus on responding to and interpreting artworks. Students look at how objects like a wilting flower, a worn boot, or a specific local fruit can represent themes like time, hard work, or Australian identity.
This unit is particularly relevant in our multicultural society, as it encourages students to consider how different cultures assign different meanings to the same object. For example, a seashell might represent a holiday to one student but a connection to saltwater Country for another. This topic is most effective when students engage in collaborative problem-solving to 'decode' still life arrangements and then create their own symbolic 'self-portraits' using only objects.
Active Learning Ideas
Formal Debate: The Meaning of the Object
Display a single, mysterious object (e.g., an old key or a cracked mirror). Divide the class into groups, each assigned a different 'perspective' (e.g., a historian, a poet, a child), and have them debate what the object symbolizes from that viewpoint.
Inquiry Circle: Cultural Symbol Hunt
Students work in groups to research how a specific object (like a bird or a bowl) is used in different cultural art traditions, including Indigenous Australian art and Asian art, presenting their findings as a visual 'map' of meanings.
Think-Pair-Share: The Symbolic Self
Students choose three items from their bags or pockets that represent a part of their personality. They explain their choices to a partner, who then suggests one additional object that could represent the student based on what they've learned about them.
Watch Out for These Misconceptions
Common MisconceptionSymbols have one fixed meaning that everyone knows.
What to Teach Instead
Meaning is often subjective and culturally dependent. Active discussion helps students realize that an object's symbolism changes based on the context of the artwork and the viewer's background.
Common MisconceptionStill life is just about drawing things accurately.
What to Teach Instead
While technical skill is involved, the 'life' in still life comes from the story. Using role-play or storytelling exercises helps students shift focus from 'what it looks like' to 'what it says.'

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.
