Week 4 of the Medford Farmers Market, the “School’s Out Summer Fun” edition, will feature live folk and children’s music from Alex Cumming from 3:30 to 5 p.m., and the acoustic guitar duo of Rishava Green and Adam Ritchie from 5 to 7 p.m. Visit the market’s website for the list of this week’s 19 vendors, which include Henna Inspired: Artwork and Design by Karyn Alzayer. Activities will include a scavenger hunt offered by the Toyary, a toy lending library platform that’s all about driving learning through play in a way that’s friendlier for the environment and for families.

Also, at 4 p.m., WalkMedford will offer a family-friendly, all-ages walk to the market from Whole Foods. Meet walk leader Audrey Stanwood at the bridge at Auburn Street for a walk along the Mystic River path. Colorful and creative attire is encouraged.

The market takes place from 3 to 7 p.m. every Thursday through October 13.
