Now about our trip to the Science Museum. It's a school holiday so you must wear<br />school uniform. When we're inside the museum you must walk quietly and behave<br />politely. Can we take photos in the museum Miss Scott? Yes you can take photos in<br />one or two rooms but you mustn't take photos when you see the no photos sign<br />and you mustn't eat or drink inside the rooms when things are on show. But miss<br />what about lunch? I didn't say you mustn't eat or drink at all Rick. There's a<br />picnic area in the museum. You can have lunch there. Great that sounds fun.
