Inquiry-based teaching methods can include the use of local resources such as school site environments and nearby natural areas. Field trips to local natural areas can be cross-curricular. Teachers can cover the standards from several content areas. When thought through carefully, field based environmental education can actually be a wise use of instructional time. It also provides an opportunity to see and experience science in action.
Environmental education is a better fit with science than all the subjects listed.
Add EE to the idea of cross-curricular instruction. In addition to visiting an area, students who regularly visit one place will assume the responsibility for making sure the animals that live there have a good habitat. Numerous groups offer free or low cost programs for students that enable them to see plant and animal adaptations in a variety of habitats. Again, these field based experiences can be cross-curricular with an easy link to instruction of the science standards. Students can study this area over the course of the school year to observe and record the changes that occur.
