Certainly! Here's an example of classical conditioning:
Imagine a dog that loves to eat. Every time the dog sees the owner carrying a bag of dog food, it starts to drool in anticipation of the food. However, the owner also has a bell that they ring before they bring out the food. At first, the sound of the bell doesn't mean anything to the dog, and it doesn't drool. But after several repetitions of ringing the bell before feeding the dog, the dog begins to associate the sound of the bell with the presence of food. Eventually, just ringing the bell is enough to make the dog drool, even if there is no food present. In this example, the sound of the bell has become a conditioned stimulus that elicits a conditioned response (drooling) because it has been associated with the unconditioned stimulus (food).
