Photosynthesis: Plant Food Production
Students will explore the process of photosynthesis, identifying its inputs and outputs through simple experiments and models.
Key Questions
- Analyze how plants convert sunlight into energy for growth.
- Explain the role of chlorophyll in the photosynthetic process.
- Predict the consequences for life on Earth if photosynthesis ceased.

About This Topic
Portraiture in 4th Class is an exploration of both identity and technical proportion. Students begin to move away from the 'smiley face' icon toward a more realistic understanding of where features sit on the skull. They learn that eyes are generally in the center of the head and that ears align with the nose. However, the NCCA curriculum also emphasizes the 'expressive' use of color. This means that once the proportions are understood, students are encouraged to use color non-literally to convey emotion, much like the Expressionist artists.
This topic is vital for self-awareness and empathy. By looking closely at their own faces and the faces of others, students recognize the subtle cues that signal emotion. They also learn that art is a tool for communication, not just a mirror of reality. This topic comes alive when students can use mirrors for self-observation and engage in role-play to explore how different facial expressions change the 'map' of the face.
Active Learning Ideas
Role Play: Emotion Mirrors
In pairs, one student acts as the 'mirror' and mimics the facial expressions of the other (e.g., surprise, anger, joy). They then freeze and use their fingers to 'measure' how the distance between features, like eyebrows and eyes, changes with each emotion.
Inquiry Circle: The Proportion Map
Students work in small groups to lay out a 'life-size' face on the floor using string. They must use 'heads' as a unit of measurement to figure out where the eyes, nose, and mouth should go based on a set of provided proportion rules.
Gallery Walk: Color and Feeling
Display portraits that use 'wild' colors (e.g., a blue face or a bright red background). Students walk around and leave 'emotion tags' next to the portraits, explaining why the specific color choice makes them feel a certain way.
Watch Out for These Misconceptions
Common MisconceptionStudents almost always place the eyes too high up on the forehead.
What to Teach Instead
Use the 'eye-line' rule by having students physically measure their own heads with their hands to find the midpoint. Active self-measurement helps them realize that the top half of the head is mostly hair and forehead, which is a surprising revelation for this age group.
Common MisconceptionChildren think skin must be painted with a single 'flesh' tone.
What to Teach Instead
Introduce the idea of 'underpainting' with blues, greens, or pinks. Show them that skin reflects many colors. A hands-on activity mixing 'rainbow skin' helps them see that every person's skin is made of a complex mix of colors, promoting both artistic skill and inclusivity.

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.

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.
