Unschooling will look like whatever your child makes it. Don't expect it to look anything like anyone else's unschooling. Though it can probably help blow your mind open to the possibilities to hear about a range of different experience with different kids in different families. So, with that in mind...
I have a 9-year-old unschooler, and her three older siblings also unschooled through the tween years. For us unschooling at age 9 seemed to involve a lot of getting out and experiencing and learning about the bigger world. Making friends, doing small but significant bits of real work (cooking for the family, yard work, volunteering for community events), taking up organized sports, learning about natural science, world history, politics, religions, geography. By age 11 it was starting to turn inwards again ... but not within the family, instead within the self. My pre-teens spent a heck of a lot of time chilling, cocooned in their bedrooms or on the couch, listening to music, reading, surfing the internet, watching videos.
My youngest can sometimes spend six hours a day on the computer. She is definitely a child with teen siblings: she loves social media, on-line TV sitcoms like Community and 30Rock, fantasy/sci-fi, nature documentaries, and on-line games like scrabble, sudoku, draw-me and such, as well as more complex games like Minecraft and Portal 2. She also reads most days. She makes her own breakfast and lunch. She often bakes muffins or cookies. She practices violin. Three or four days a week she gets out for some exercise: volleyball, gymnastics, mountain-biking, trail-running, snowshoeing, eg.. She likes doing a bit of bookwork; maybe an hour three or four days a week. She has a few organized activities she attends: gymnastics, a violin master class, an occasional civics homeschoolers' workshop, a weekly art class. She likes to run errands with me, whether to the post office, or driving the older kids places, or shopping. She sometimes listens to podcasts, watches the news, reads the newspaper. She hangs out with friends and siblings. And she talks .... just keeps up a flow of conversation with whoever is available, offering thoughts and ideas, asking questions, listening, observing, thinking aloud, taking stuff in.
Occasionally she delves into something with gusto, persistence and a long-term goal. A year and a half ago she decided to collect wild herbs and fruits and roots, dry them, craft herbal tea blends and sell them at the local market. A few weeks ago she wanted to build a topographical map representing our local region and created a stunning layered 3D model. Last summer she decided to learn to read the alto clef on viola and worked hard at it for a few weeks until she mastered it. These deep learning jags don't happen often with her, but they are reassuring when they take place.
So in summary, her learning is mostly pretty capricious, except for the scheduled out-of-home activities. Some days make her unschooling look pretty lazy and unproductive. But the net result over the long term is a pretty darn robust education.
