School/group staff (teachers, paras) are free, as such we do expect that you make sure your students use our space appropriately. Additional guests or visitors are at the $9 admission fee. Please be sure to let us know how many adults to expect. Also, during your visit, we expect all adults to supervise your group, correcting any misbehavior on the part of students. All guests are expected to be respectful and follow our posted rules. While exhibits can break down from normal use, willful damage will not be tolerated. While not all of our exhibits are intuitive, and may need an adult to help explain how to use them, this shared learning is a part of the fun you get to have with your students.
