The Return of the Third-Grade Ghosthunters by Grace Maccarone, 1989.
This is part of the Third Grade Ghosthunters series.
The same kids who were assigned to figure out the mysterious happenings at their school are now going on a field trip to a farm with their class. They’ll be spending a couple of days on the farm, sleeping over. Adam has been looking forward to the trip, and he brings his ghost hunting gear with him, just in case. He hasn’t lost his taste for ghost stories since their last adventure.
At first, things are pretty normal. Then, during the night, the boys hear howling and see apparitions of a ghostly wolf in their bunk house. Could the farm be haunted? Or is this some kind of mean joke? Perhaps it’s the work of the class bully, Jeff? The ghost hunting committee assembles again to solve the mystery.
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 solution has an interesting twist to it. It’s a good mystery for kids beginning chapter books who like a little creepiness in their reading.
The book is currently available online through Internet Archive.
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 Treasure of Kilvarra by Elizabeth Baldwin Hazelton, 1974.
Without the amulet to protect her, Christie continues her search for the treasure. An accidental injury takes her to the place where it is hidden, but it’s a dangerous place. Caught in a terrible storm, the children explore an ancient stone tower. There, Christie sees the ghost of a long-dead monk, gesturing to her, begging her to follow him to the treasure that she seeks. The monk died protecting it, and it’s a very unexpected but wonderful treasure indeed. But, getting out of the place is going to be even more dangerous than getting in.
The Dastardly Murder of Dirty Pete by Eth Clifford, 1981.
Harry Onetree and the girls find a ghost town with a hotel, an opera house, and several other buildings. Although Harry only means to look around for a little while, he forgets to set his parking brake (something else Mary Rose warns him about, which he ignores), and their car rolls backward into a ditch. Since it’s getting dark, they’re stranded in the ghost town for the night. But, they’re not alone there.
The Ghost that Came Alive by Vic Crume, 1975.
They tell the kids that the house is supposed to be haunted and people can often hear the ghost of Andrea Cliff calling out in the night. The kids soon hear this spooky voice themselves, calling for help. Trapped in the house with the ghost and unfriendly people, the Blairs decide that they have to figure out what’s really going on, but the danger is worse than they know, and Jenny’s premonition of doom is getting stronger all the time . .
The Case of the Haunted Health Club by Carol Farley, 1991.
Flee Jay thinks this is spooky, but Clarice doesn’t believe in spirits. In order to investigate further, the two girls accept part time jobs helping the fortune teller and her nephew to clean up the building so they can move in new exercise equipment. “The spirits” continue sending warnings in the form of red dye in the Jacuzzi and threatening messages. Clever Clarice uses logic to point out how most of these things were accomplished but is surprised when Flee Jay reveals something that she overlooked.
