Hesston College will host an Earth Day celebration from 10 a.m. to 2 p.m. April 18 on the Hesston College campus. The come-and-go event is free and open to the public.

Coming just after the college’s week-long Sustainability Week followed by a week-long Wellness Week, the day’s theme will be “Lean, Clean and Thinking Green.” Activities will focus on conservation, recycling and solar energy and how to make those principles sustainable for the long term.

Classes and individuals from the science and math departments will present conservation methods for energy and water.

Physics students will offer presentations and rides on the electric bicycle and tricycle and will display a mode of a fuel cell car. They will also present a solar design for producing electricity for the campus science bulding. Nick King of King Solar in Hutchinson, Kan., will be on hand to answer questions and discuss solar photovoltaic installations. Environmental biology students will present information about their classroom material while microbiology students talk about water treatment. Members of the Hesston College Maintenance and Facilities staff will also talk about conservation efforts on campus.

Solar-cooked snacks will be offered from 11:30 a.m. to 1 p.m.
