Here at Repair the World, we are service nerds and proud of it – the kind of people who think every day offers fantastic opportunities to volunteer and make a difference. So let’s just say we’re extra excited this week. Not because the weather’s been so lovely, but because it’s National Volunteer Week!

Today through April 21, people across the country are honoring America’s long tradition of service and volunteerism (seriously, it goes way back), and celebrating all the people who take time out of their days to make their communities and the world a better place.

Volunteering comes in all shapes and sizes, from helping a neighbor plant a garden or a local school paint a mural, to spending an evening at a soup kitchen or tutoring a student, lending your skills to a non-profit organization or embarking on a immersive service learning adventure. So for this National Volunteer Week, find your volunteer bliss (here are some ideas to get you started) and put your free time to great use.

To sweeten the pot, your do-gooding could win you great prizes. The Vermont-based, farmer-owned dairy cooperative, Cabot, created Reward Volunteers, a mobile app that lets volunteers age 13 and up log their service hours and win prizes for themselves and the organizations they help. Despite being hosted by a dairy coop, the prizes are definitely not cheesy – you can win ski passes, cash prizes, and even a cruise to Alaska – all for taking the time to help others.

Find out how to log your hours with Reward Volunteers here, and let us know how you’re celebrating National Volunteer Week below or by tweeting us at @repairtheworld!
