The Farmers' Markets are hopping this weekend. The Roslindale market has free Salsa lessons for all ages, and the Braintree Market has a Kids' Day full of fun activities to get kids thinking about where their food comes from and how to eat healthy. Fans of Judy Moody can celebrate the release of the new book at Judy Moody Day. The Harvard Museum of Natural History invites budding entomologists and their families to explore the science of bugs together. If you are looking to catch a movie, Muppets from Space is showing in Arlington and Finding Nemo is playing at the Prudential Center Garden this weekend. Art lovers should be sure to check out the Watson Adventures: Cats vs. Dogs Scavenger Hunt at the MFA. And if you are looking for live entertainment, check out Sir George and the Dragon at the Puppet Showplace Theater or Gustefer Yellowgold in concert.

Ah, school.  It's kind of good, isn't it? I mean because of all the learnin' and edumacating, of course. My state of near-bliss would have nothing to do with a small but meaningful number of hours during which my kid may or may not be in someone else's care under someone else's tutelage. Nope, it's all about the smartifying.

Once the homework's done, we still have time to play. This weekend offers plenty of opportunity, what with a really big rubber duck, a chance to make use of all those Frozen lyrics you've memorized, and, if you're of a certain generation, a chance to make use of all those Beatles lyrics you've memorized. You can watch dogs play in the snow (because that's totally a summer thing), or enjoy a regatta of boats made out of cardboard. (Would they even float? Because I think I just learned something. Hello, edumacating!)
 
You can also watch planes fly, get your fiesta on in Culver City, catch a bunch of outdoor movies and concerts (better hurry, the season on those is drawing to a close), learn how to talk about art, and make some art of your own. School may be in session, but you can still keep the summer fun going!

Summer is coming to an end, and your kids want to continue to do the amazing things they were introduced to in a STEM summer camp. They’re in luck, because the STEM/STEAM (the A adds Arts) offerings for kids in Boston extend into the school year. Check out these places offering unique classes that encourage them to use their creativity while learning STEM-related skills. (Take a look at some really cool places for STEM birthday parties, too.)

Sports, sprinklers, sing-alongs and lots of summer fun are all on tap for the weekend, the second to last one before the kids go back to school. Two of our top picks for the month take place this weekend. On Saturday, head to the Billie Jean King National Tennis Center for FREE tennis clinics, games and face time with pros at the annual Arthur Ashe Kids' Day, or catch the last weekend of family-friendly FringeJr theater shows.

Other cool options include NYC Audubon's annual Shorebird Festival in Queens and a Volkswagen show on Governors Island.

These are just a few of the great things going on this weekend. All of our best bets are below. You can find additional options in our Event Calendar and our Summer Fun Guide.

September may be just around the corner, but we still have a few summer weekends left to squeeze in warm weather outings! Don’t let the month of August go by without checking out one of the great festivals in NJ, like the Canal Day Music & Craft Festival or the Long Branch Jazz & Blues Festival. Duck indoors for a few hours and take in a production of the kid-friendly musical Willy Wonka Jr. at the Surflight Theatre or soak up all you can of the great outdoors with Bats for Beginners at Tenafly Nature Center or a Guided Hike at the NJ Botanical Gardens. Also, you can check out the full list of weekend activities on our Event Calendar and don't miss our Summer of Play Guide with 100s of ideas for a fun, playful, and tech-free summer!
