This is the third in a series of exercises designed for my elementary and middle school students. The activity helps students develop foundational shading skills through exploring the techniques used to render a translucent object with an iridescent surface.
Students are guided to:
1. Demonstrate Precision and Control
Use a compass to draw a clean, accurate circle (maximum 2.5")
Maintain neat edges and careful pencil control within a small format
2. Build Colour Intensity on Black Paper
Layer coloured pencils effectively on black paper to create visible, vibrant colour
Understand how darker surfaces affect colour brightness and layering
3. Apply Iridescent Colour Blending
Blend a range of colours smoothly to create an iridescent (rainbow-like) effect
Transition between colours without muddying or over-blending
4. Use Highlights and Contrast to Create Transparency
Apply bright highlights and strong contrast to make the bubble appear glossy and see-through
Use the black paper strategically as part of the shading
5. Create the Illusion of Form and Volume
Use curved colour bands and value changes to show the round, spherical shape of the bubble
Suggest light wrapping around the surface
The Bubble Exercise
Class of 2025-26 Grade 7
Students really engaged with this exercise as we got to explore using brighter and more vibrant colours. Throughout the lesson, students engaged in replicating by breaking complex details down into simple shapes, creating coloured gradients based on the techniques learned in the matte sphere exercise, and closely following demonstrations shown on a large screen.
They demonstrated patience, perseverance, and a willingness to work through moments of discomfort and self-doubt. I am deeply proud of their effort and focus throughout the process.
