The story

Eddie carries a wooden tray into the classroom, with a shiny wrapper, an empty jar and some paper on it, while Zara and Isla look on.

Eddie brought a tray of mystery objects to the classroom: a shiny wrapper, an empty jam jar and some plain paper.

Zara bends the edge of the wrapper to show its shiny inside, with Isla beside her and Eddie looking surprised.

Zara bent the wrapper. It looked like paper on the outside, but it was shiny on the inside.

Priya, in clear glasses and blue gloves, looks at the wrapper through a magnifying glass while Isla checks a tablet.

Priya looked closely at the edge, and Isla checked the descriptions and the local guidance.

Priya: “Let’s find out what it’s made of.”

Zara holds up the wrapper and asks a question while Priya listens, with Isla behind them.

Zara asked where the wrapper should go. Priya listened carefully. They couldn’t be sure yet.

Zara puts the wrapper on its own small tray with a blank card clipped to it, while Priya and Isla watch. The jar and paper stay on the big tray.

So the wrapper went on its own tray, to be checked, instead of a guess.

For grown-ups: Not sure what something is made of? Keep it to one side and check your council’s own list, rather than guessing.

Isla and Zara clip a small card with a drawing of a jar and paper to the classroom display, with Priya nearby. The wrapper waits on its own tray.

Isla and Zara made a class card for the things they had checked. The wrapper waits until someone knows for sure.

Draft, 20 October 2026. The words and pictures are not yet reviewed by an educator. The story follows the outline in our story guide.

The real-life bit

Some packaging is made of more than one material, like paper with a shiny lining. It isn’t always clear which bin it belongs in, and councils have different rules. If you’re not sure, a grown-up can check your council’s website. Gullbrae is made up. Your council’s own rules are the ones to follow.
