A group of fourth- through sixth-graders is spending time this summer talking about and acting on ways they can make a difference during Northwest Library's aptly named Make a Difference Club.

The club, which met for the first time on June 21 and will continue to meet on Tuesdays at 4 p.m. through July 12, has already discussed ways to help the elderly. Suggestions ranged from mowing their lawns and holding doors open for them to listening to and remembering their stories. The 18 participants made Fourth of July cards for the library's homebound patrons.

Planting seeds and seedlings was the activity for last week's session, during which kids discussed ways to improve the environment.

During future get-togethers, ways to help animals (where those attending can make catnip toys for the Capital Area Humane Society) and make a difference in the community will be considered.

In addition to the Make a Difference Club, Worthington Libraries has several programs planned for fourth- through sixth-graders.

Fans of the Harry Potter series are invited to a magical night this Friday, July 8, at 5:30 p.m. at Northwest Library. Games and a costume contest will be followed by a Harry & the Potters concert at 7 p.m. in the library's back yard. Don't miss songs like "Gryffindor Rocks," "The Missing Arm of Viktor Krum" and "Slug Club!"

Old Worthington Library will host a Wiffleball Home Run Derby on Tuesday, July 12, at 2 p.m., where competitors get 10 pitches but can earn more by correctly answering literature and sports trivia questions.

Tweens can also take on members of the Columbus Clippers baseball team during a Wii Baseball contest, scheduled at Old Worthington Library on July 15 at 11 a.m.

Safety pins, soda tabs, duct tape and other items will be transformed into stylish accessories during Trash to Trendy: Accessorize, which will be held at Worthington Park Library on July 21 at 2:30 p.m.
