Most kids love watching any sort of construction going on. It could be a house, a street, a high rise, anything. It’s a fascinating process.
If you know of some going on in your area, with a good, safe place to watch for a time, it can be a fun thing to do with the kids. You can talk about what goes into making a building and the different tools and equipment they’re using.
It’s also a good activity to do over time if it’s close enough. Go by once a week or so and see the changes. So long as there’s decent progress it can be pretty impressive.
