Roasting a marshmallow using reflected sunlight was part of the fun at the Tucson Earth Day Festival in 2011. This year’s celebration will take place at The Children’s Museum Tucson.

Pima County Department of Environmental Quality will join the Tucson Earth Day Festival celebration Saturday, April 21, at the downtown Children’s Museum Tucson and Armory Park at 200 S. Sixth Avenue.

The festival is free and runs from 10 a.m. to 2 p.m. Dozens of exhibitors will offer interactive hands-on activities, sharing information and displays related to transportation choices, native plants, healthy air, water conservation, sustainability, energy efficiency, waste reduction and more eco-minded topics.

Numerous opportunities will be available to discover how helping the planet helps you, too.

Because April is Bike Fest month, consider riding your bike to the event and safely park at the free Bike Valet Parking area. The Sun Link Streetcar and Ronstadt Transit Center are a short walk away from the festivities.

The Children’s Museum Tucson will be free for the day (adults must be accompanied by children, and children must be supervised by adults).

The Department of Environmental Quality, along with other Pima County departments, sponsors the Tucson Earth Day Festival to promote a healthy, sustainable community. At DEQ’s booth, play the Spin & Learn Wheel of Wisdom to test your environmental acumen and win a prize.
