Preparation
Make rice glue for class.

Warm-up and introduction: 10 mins
- Ask children to think about the following before they begin: What will be on your waste mountain? Cars? Toilets? Paint tins? Toys? Rats? Bottles? Seagulls? Where is your mountain – in the city, countryside, by the sea, dumped in a river? You may add extra details such as: birds flying above it.

Development: 40 mins
- Invite children to draw a life-size plastic bottle in outline on paper. Instruct them to start with darks, tearing or cutting out shapes from colour sheets to stick into their outline. Ask them to build up the image of bottle in three tones from dark to light.
- Instruct students to apply rice glue with brush and allow to dry.
Each child should try to make as many images of waste objects as possible and work together on further images. When dry, cut out all collages and assemble into a large group image to create a gigantic waste mountain. Children can also cut shapes out of coloured printed papers to add to the waste mountain.
- Ask children to decide how big they want their waste mountain to be. Invite them to use lining paper sheets as a base and if their mountain is enormous, to stick several lining papers together.
- Encourage students to draw out their mountain shape. Using a wash* of brown printing ink and some brushes, ask them to stain their mountain brown.
- When this is dry, invite them to start at the bottom of the mountain and stick their collage objects.

Conclusion: 10 mins
- When complete, discuss and talk to children about how to prevent creating real waste mountains.
- Discuss the possibility of writing a story inspired by the waste mountain, and raising awareness within the school.
* A wash is a small amount of ink diluted with water.
