Okay, so imagine we have a pig. Like Wilbur from Charlotte's Web. Now, when we want to make something yummy out of him, we can take his belly and cut it into thin strips. These strips are bacon! We usually cook them on a pan or in the oven until they are crispy and delicious.
Now, if we want something different, we can take other parts of the pig and turn them into ham. Ham is usually from the pig's back legs. We take the meat and put it in a salty solution or smoke it to give it a special flavor.
So, bacon and ham are both made from pigs, but they come from different parts of the pig and have different tastes. Bacon is crispy and savory while ham is salty and meaty. Both are very yummy, but some people might like one more than the other.
