Yes! Colibrita, I have taken my students into town and walked around asking them Vocabulary questions.
I have also been able to explain aspects of British culture which they saw, but didn �t understand.
I asked lots of questions.
"What is the name of that, in the station/shop/house/cinema/hotel/etc?"
"How many cars/people/children/doors/etc. are there here?"
"How many colours can you see? As you say the name, point to the colour, please."
"Tell me the name of something that you can see which is --- green/made of wood/moving/a person/something you can eat/an animal/etc. Point where it is, please!"
"I Spy with my Little Eye, Something beginning with �S �, and then everyone must try to guess what it is. Snake? --- No! Shop? --- No! Sausage --- Yes, Maria, Sausage! Now it �s your turn, Maria."
"I can see a Taxi. Can anyone spell �Taxi � for me?"
"What is the name of that man in the blue uniform?"
"Tell us the work that he does, please."
"What is the name of this shop?"
"Tell me 6 things that they sell in this shop."
"We can see the traffic lights. What will be the next colour?"
"We are in the fruit shop/etc. What is the name of this vegetable/fruit/flower? How do you spell it?"
"Students, I want you to make notes, and when we return to Class, I want you to write a short essay, describing 5 interesting things that you saw today."
"Maria, you are a stranger in this town. Robert, you live in this town. Maria, you want to go to the Toilets/Museum/Supermarket/Cinema/House Number 25/Nearest Lamp Post/etc. (which is near us) so you ask Robert the directions. Robert, you give Maria directions from here to that place. You must both use polite Greetings and Farewells".
"Students, from here, if we walk straight ahead and take the first left, what can we see/what is the name of the Street/are we in the Park or at the Railway Station/etc?
If there is a Park, an Open-Air-Market, Street Entertainment, a River, a Farm, a Railway Station, etc. these can be excellent topics.
I hope that I have helped.
