Fall is in full-swing, which in New England means cooler air, a shower threat, some wind, some warm sun—basically a weather salad. That’s what’s forecast this weekend, too.

Newton has a plethora of fall fun for the whole family, especially on Sunday. Take in a concert or a book talk. Bring the kids to a farm or take them on a hayride.

Here are five things to do in Newton this weekend:

Saturday, Oct. 5

At 1 p.m., The Scandinavian Cultural Center will host a book talk by Sally Fronson about her new book, “Big in Sweden,” a coming-of-age novel. Admission is free, but registration is requested.

Sunday, Oct. 6

From 10 to 11:30 a.m., All Newton Music School will host a Con Brio Sunday Brunch Concert featuring violist Scott Woolweaver, who has curated a program of songs inspired by Mozart, Bach, Tchaikovsky and more. There will be sandwiches, coffee and orange juice. Admission $35.

From 9:30 a.m. to noon, the Newton Community Farm at 303 Nahanton St. is hosting a Fall Family Party featuring pumpkin decorating, scavenger hunts, seedling guessing games, and more. Admission is free.

From noon to 4 p.m., Historic Newton is hosting Newton Hayfest, where all ages can learn to churn butter, dip candles, press apples, and other 19th century activities. This is at the Jackson Homestead at 527 Washington St., and you can drop in at any time from noon to 4 p.m.

From 3 to 5 p.m., the Classical with a Twist series kicks off the Cherry Street Music season at The Allen Center with a concert, “Champions for Change,” featuring works in honor of Mstislav Rostropovich, a musician and staunch human rights advocate, performed by CSM Director Allison Eldredge, Max Levinson and Andres Guerra. The concert will include compositions from Prokofiev, Chopin and film composers Maurice Jarre (“Dr. Zhivago”) and John Williams (“Memoirs of a Geisha”).
