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

6. Observe and Represent Light Effects

Identify and draw re ections, colour shifts, and light patterns typical of soap bubbles

Understand that bubbles reflect and refract light in complex ways

7. Work Within Material Limitations

Adapt techniques to suit Prismacolor Scholar pencils (lighter pressure, layering, burnishing where appropriate)

Make intentional choices based on the tools provided

8. Develop Craftsmanship and Presentation

Produce a clean, refined final drawing with crisp highlights, smooth blends, and controlled edges

Present work that demonstrates attention to detail and care
