  • Teacher Surveys for teachers will be provided at the end of the field trip experience. This feedback is important to us so that we can ensure that the activities we share with the students are meaningful and help teachers meet state science standards for science.

  • Student Pre and Post Survey may be required* for students. A link will be provided and will be the responsibility of the teacher to ensure that students complete it in a timely manner before and after the visits. Failure to complete these requirements may affect your chances of attending future EDI field trips.

  • Photo Release Forms should be printed and sent home with students prior to first field trip visit. It is important to EDI to share photos with grant partners to see progress of our programs and to apply for future funding. Forms can be found here. Please let the coordinator know day of anyone who cannot be photographed.

  • Chaperones are LIMITED TO ONE PER CLASSROOM. If you have a special situation please contact the education coordinator at It will be your responsibility to inform the chaperones of their duties. Unfortunately, we have had several disruptive chaperones and would like to avoid these situations when possible to ensure the quality of the experience for all students. Please choose wisely.

    • We ask that parents/chaperones do not talk on their cell phone during their visit especially when they are with a group.

    • We ask that parents/chaperones do not talk over the field instructor or carry on conversations with other chaperones or with the students when information is being share by the field instructor.

    • We ask that parents/chaperones do not feed students while on the trails. Each field instructor has a designated break time (normally right after the hike) for students to grab a quick drink of water, a rest in the shade and use the restroom.

    • We ask that parents/chaperones do not disrupt the group to take photos of their students. Please only take action shots that do not require that the students be pulled away from the activity. There will be time during lunch for photo ops.

    • EDI will ask a parent to leave the group if they are being disruptive and affecting the quality of the experience for other students.

    • PLEASE! PLEASE! PLEASE! Choose your chaperone wisely and explain to them that this is an educational field trip and that we are sharing important information with the students that supports their classroom learning.
