      Sketchbook experimentation: water-like marks

      Lesson details

      Learning outcome

      I can use watercolours and a paintbrush with increasing control

      Key learning points

      1. Know how to care for a paintbrush
      2. Know how to use a paintbrush to create a wide variety of marks with watercolour
      3. Use marks to depict water, including reflections

      Keywords

      • Paintbrush - a tool that you use to put paint on paper

      • Watercolour - a type of paint that you mix with water to make it look soft and see-through

      • Reflections - when you see an image of something in a shiny surface, like water

      Common misconception

      Paintbrushes can be left dirty and used again without cleaning.

      Remind children that paintbrushes like to be cleaned and left on top of water pots so the next artist can use them.

      Teacher tip

      For this activity, pupils could be seated at tables or use a vertical surface to experiment with a variety of marks.

      Equipment

      paintbrushes in a variety of sizes, watercolour palettes, waterpots
