It’s that peculiar time in early spring when the buds are about ready to bloom but the ground is saturated in mud and the air has a lingering chill to it.

It’s nice outside at times, but also gross. And this weekend may be a little cool. Fortunately, Newton has a bunch of fun family-friendly ways to keep you entertained indoors, as well as a big outdoor cleanup for those who prefer the outdoors.

Here are seven things to do in Newton this weekend.

Friday, April 24

At 7 p.m., St. Ignatius Church, 28 Commonwealth Ave., will host a concert featuring Franz Schubert’s Death and the Maiden quartet.  Suggested donation is $20.

From 10 a.m. to noon, the Charles River Watershed Association will host its annual Earth Day Charles River Cleanup, bringing together thousands of volunteers to pick up litter, remove invasive species and help with park maintenance along all 80 miles of the Charles River. Volunteers should bring their own gloves. Trash bags, picker-uppers, and other cleanup materials will be supplied to participants. Contact CWRA to see which spots are open.
