Another time on The Simpsons in "Lisa the Simpson" Lisa forgot about a school agriculture project, so she makes a pig by sticking some pushpins into an eraser.
Which was done earlier in Simpsons Comics. Ralph Wiggum entered the same thing in a school art show. He didn't place.
From a Halloween episode:
Bart: From 'A' apple to 'Z' zebra, Baby's First Popup Book is 26 pages of alphabetical adventure!
Ms. Krabappel: Bart, you mean to tell me you read a book intended for preschoolers?
Bart: Well, most of it.
Holden from The Catcher in the Rye, wrote a hilarious and definitely unresearched exam essay on the Egyptians.
Sam on iCarly once turned in an orange for a project about environmental efficiency. She got an A. Inverted in the same episode when Freddie and Carly each do elaborate projects (Carly created an electric scooter, Freddie a large composter) and they both fail, having to go on a root and berry trip with their teacher.
Calvin and Hobbes: Calvin writes a report about bats in which he calls them bugs, uses a lot of vampire myths, and includes an "illustration" consisting of the Batman logo with fangs added. He thinks that having a professional binder will cover up for his lack of research, but it backfires when everyone in the class calls him out for saying bats are bugs.
Another time, Calvin and Susie had to do a joint presentation about the planet Mercury. Despite regular reminders from Susie, Calvin failed to do any research for his part of the talk, tried to stall for time by launching into a Stand-Up Comedy routine, and in the end simply made up outrageous things on the spot. Cue Susie advancing toward him with her fist.
Dave Barry has a few columns about this. In one, he describes one of his projects as being entitled "The Phases of the Moon", consisting of a styrofoam ball, half of it scribbled black with a pen, on a string. He goes on to say that his fellow students found it amusing to use the ball in their own projects, so he ended up with a big Official Science Fair Project Cardboard and nothing else. His wife's project (Movement of the Waves) was described as a pan of water in which a pen was swished around, causing waves.
A Robot Chicken skit begins with an elaborate battle between costumed heroes and villains, one of whom is called Mockingbird. The skit then cuts to a classroom, revealing the whole thing was a kid's attempt at a book report on "To Kill a Mockingbird". The teacher sighs, "Couldn't even spring for the Cliff's Notes, huh?"
A young Shawn from Psych did a book report on Charlotte's Web without reading to the end. Failure ensued.
There's a Saved by the Bell episode in which Zack needs to do a family heritage project. All he knows is that he is part Native American, so he just uses a whole bunch of stereotypes (and Screech) to present his project. You bet your life he's forced to redo his project.
Including one biology project on whether or not plants sneeze.
Played with and subverted in The Troop: Jake forgot to do his potato clock for school, but Felix didn't. It would obviously be identified as a Felix project if it was perfect, so he "Jaked it up" a little to get Jake a passing grade but not an A.
Peter has a habit of doing this in FoxTrot, including writing an essay on Moby-Dick in two and a half hours.
On an early Boy Meets World episode, Feeny assigns the class a project on what their future might be like. Cory just shows up in a baseball uniform and claims he'll be a pro ballplayer. Feeny's line of questioning shows that Cory hasn't put much thought into it, and he is given a chance to try again.
In Osmosis Jones, during a Flashback to a science fair, a struggling student was given a project about using oysters to filter water. The teacher remarks that the student most likely just started the project the morning of the science fair, but that she was going to give him an A anyway to give him a leg up. Mr. DiTorre ate one of the oysters, and Ozzy made him puke. Which got Ozzy "suspended for use of unnecessary force."
Brick from The Middle often has to do these - paradoxically, he's probably the smartest of the Heck kids, but he gets distracted easily at school, and thus is not paying attention when the assignment is handed out. One notable example is when he's elected class historian and has one whole year to do a slideshow for graduation day. He doesn't remember to do it until a week before.
