Beware the Fish! by Gordon Korman, 1980.
In spite of MacDonald Hall’s prestigious reputation, it is continually plagued by money problems. The students can’t help but notice all the budget cutbacks, and now, there are rumors that the school might even have to close permanently. The last thing anyone wants is to leave MacDonald Hall. Bruno, the school’s resident idea man and master prankster, decides to spearhead a movement to raise money and publicity for MacDonald Hall so they can save the school!
Bruno, his best friend Boots, and their other fellow students try everything they can think of to spread the word about what a great place MacDonald Hall is so that enrollment will go up and the school can earn enough money to stay open. They enlist the help of the girls at the nearby finishing school to help them break a world record. The school’s science whiz, Elmer, shows the boys some of his inventions in the hope that one of them will make the school famous.
Unfortunately, as usual, nothing turns out as planned. World records are extremely difficult to break, and Elmer’s inventions backfire. One of his inventions backfires in such a way that it comes to the attention of the local police, and even the government becomes convinced that a gang of terrorists may be operating somewhere in the vicinity of MacDonald Hall.
The boys try to keep their activities secret from their headmaster, Mr. Sturgeon (or, as the boys nickname him, “The Fish”), while government agents snoop around, looking for the head of the organization that’s been issuing cryptic messages over television signals, a shadowy figure known only as “The Fish.”
This book is part of the MacDonald Hall Series (or Bruno and Boots series). It is currently available online through Internet Archive.

When they reach the state park, Dennis Ten Foot Bridge, who is the last of his tribe, tells the students about his tribe, teaches them wilderness skills, and leads them in group activities. One evening, Joey goes out to practice some rowing on the lake by himself, and he sees what looks like a large ghost at the top of a hill However, everyone knows that Joey lies about a lot of things, so at first, no one believes him. At least, no one except Adam.
The Return of the Third-Grade Ghosthunters by Grace Maccarone, 1989.
They try to use scientific methods to study the haunting. They measure the placement of the furniture to see if anything moves while they’re out and sprinkle flour on the floor to get footprints. But, even though they watch carefully and don’t see anyone enter the bunk house, when they go inside, everything is a mess, and the flour doesn’t appear disturbed. Everyone else is about ready to admit that this one is a real ghost, but Adam has another theory.
The Haunting of Grade Three by Grace Maccarone, 1984.
Most of the group members are misfits in one way or another. Norma Hamburger is a shy girl, frequently teased about her last name. Debbie Clark is a talkative girl who’s really into science. Chuck Webber, Adam’s best friend, is the class clown, always telling stupid jokes (and one of the main people who teases Norma about her name). Danny Biddicker is strong and good at sports, but he worries that he’s not as smart as the others. Joey Baker feels overshadowed by his large family, so he tells tall tales to get attention. The other kids don’t understand and get annoyed with his lies. By working together, they not only learn the secret of Blackwell House, but they learn more about each other and become a real team and friends.
The D- Poems of Jeremy Bloom by Gordon Korman and Bernice Korman, 1992.
Jeremy tries to make the best of things, but somehow (partly through his own fault and partly by accident), he continually manages to do things to annoy his poetry teacher, Ms. Terranova (or, as the kids call her, Ms. Pterodactyl, thanks to a mistake Jeremy made when he said her name on the first day of class). Every single poem Jeremy writes during the year receives the same grade: D-. The book is divided into different periods of Jeremy’s work, along with an explanation about what Jeremy did during each period to tick off his teacher. At the end, the reader can be the judge: Are Jeremy’s D- grades because he’s a terrible poet or because his teacher is mad at Jeremy for everything else he does during the year? (The answer is pretty obvious.)
