Eligibility Criteria

• Age: 8 Years - 11 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Child (0-17)

You may qualify if:

• English-speaking families that agree to participate; 3) residents of SNAP-eligible communities in Franklin County, Ohio.

You may not qualify if:

• Inability to functionally participate in harvesting; accommodations can be implemented in the future for children with special needs
