# Activity: Bee-Free Barbecue

If you've ever been pestered by bees at a picnic, you might think that a barbecue would be better if there were no bees at all.

Not so! Without the bees to pollinate crops, your barbecue would have no mustard, no ketchup, no pickles, no lemonade.

In this activity from the Smithsonian, students explore what foods the barbecue would be missing if there were no bees. A student handout and teacher instructions are provided.
