They are hives, welt hives to be exact. You sound like you are allergic to pollen. As you are a minor, ask your parents to arrange a allergy test for you so you know what your allergies are. They will tell you if you are a little allergic or a lot allergic to certain things. For the hives, ask your parents to get some dye free benedryl. I recommend dye free, as it is less drowsy then. On your field trip try taking some benedryl throughou the day (follow the directions on the box). But ask mom and dad first hon.
