Choosing a field trip location Field trip locations pre-approved for bus funding We have developed a list of field trip locations and activities that are pre-approved for bus transportation from Hennepin County. See the pre-approved environmental field trip locations (PDF) for sites and activities. Field trip locations not pre-approved for bus funding You can go to field trip sites not listed in this document, but you will have to provide more details about the field trip location and activities and how they align with the county’s goals for this program. Field trips must occur within the seven-county Twin Cities metro area. Field trips that haven’t been pre-approved for bus funding should address one of the following topics: Preventing waste, recycling and properly disposing of hazardous waste: Topics covered include what can be recycled in our community, how the recycling process works, what products are made from recycled materials, and why recycling is important. Additional topics covered include preventing waste, reusing materials and resources, identifying and properly disposing of hazardous materials, and reducing the amount of hazardous products we use. Sustainability and green infrastructure: Explore how humans interact with the environment to get things we need like food, water and energy, how we can build infrastructure that protects the environment, and what actions we can take to be good stewards. Topics may include farming and food systems, green building, renewable energy, and water infrastructure. Understanding ecosystems: Learn about what an ecosystem is, how we impact ecosystems, and what we can do to protect, preserve and enhance ecosystems. Activities illustrate human interaction and impact on our environment and the plants and animals that live in it.
