You may be surprised to learn that many grocery stores offer field trips to young children. If you can get a group together, most are more than willing to give your children a behind the scenes tour. You can visit the back where the milk and eggs are stocked and feel how cold it is. Sometimes you can see where they store the fresh meat (yuck!). They will give you a tour of the produce section. And many will take you to the back of the bakery, where you can see how cookies are made and even sample some goodies. This is a quick, fast-paced tour that most children enjoy! If you can’t get a group together, lead them on a tour yourself. Show them the different types of fruits and vegetables. Maybe even let them each pick one out to buy and take home to try. You could even ask the people behind the counters more about what they do.
As an extension, it would be fun to set up your own grocery store at home based on what you saw on your field trip. You can save old cereal boxes and clean out milk containers and the likes for this. How fun (and educational) would this be!
