Yes, as long as it was a required trip by the school.
Per Illinois Publication 132, page 3 linked to below.
You will be allowed 25 percent of your student’s qualified
education expenses after the first $250. Your total credit may
not exceed $500 in any year, regardless of the number of
qualifying students.
What are qualified education expenses?
In general, qualified education expenses are the amounts paid
in excess of $250 for tuition, book fees, and lab fees at the
school where the student is enrolled in kindergarten through
twelfth grade during the regular school year.
Specifically, qualified education expenses include the amount of
tuition (including summer school classes required for
elementary or secondary graduation requirements).
book fees paid for the rental of books that were required as a
part of the school’s education program.
lab fees paid for the use of supplies, equipment, materials, or
instruments that were required as part of a lab course in the
school’s education program.
For example, if you rented a musical instrument from the
school (not from a business)
for a class, or
for participation in an extracurricular activity that resulted
in a credit toward completion of the school’s education
program,
this rental expense qualifies as an education expense.
