I saw a craft where layers of cheesecloth were dipped in liquid starch and then draped over a detergent bottle that had a pipecleaner wound around the neck to make raised arms. The bump over the lid becomes the ghosts head, the raised arms lift the cheesecloth for ghostly arms and the cloth was left to puddle which makes a base. When it all hardens the ghost can stand on its own, its see through and very ghostly. They added black shapes for eyes and mouth. I used the ghost for several years before it eventually collapsed.
There's a cute spider craft that I like to make. You take black paper (I think 1/2 a sheet will work) and fold it into a cone shape then tape it or glue it in that shape. Then you use another color and cut it into 8 strips and fold the strips back and forth (to make the accordion?? style fold) and then tape or glue those to the bottom of the black paper, these are your spider legs. Add eyes and attach a string to the top of black paper (the top of the cone) and hang it up! Sorry I am writing this from memory, so I hope this makes sense!
You could have students draw haunted houses. Post them up in your classroom or outside your classroom, and have students vote for the best haunted house. Give 1st, 2nd, and 3rd place ribbons out to the winners. You could also announce the winners over the intercom.
I have done the cheesecloth ghosts with my classes for years. We do it on a Friday afternoon so the ghosts can dry all weekend. The kids love it, many get very creative about draping their cheesecloth.
I usually ask for donations of small kid-size water bottles, this way the form is weighted, and use strips of aluminum foil to create arms around the neck of the bottle. I pour liquid starch into large bowls and the kids dip their cheesecloth and then drape over the form they have created.
You can buy it at the grocery store or a kitchen supply store - I'd check the dollar store in the kitchen section. Lots of people wrap their dressing in it before stuffing it into the turkey, makes it easy to remove. You also use it for straining stuff like yogurt. (I had a recipe recently that called for yogurt cheese made that way.)
on Dead Explorers for the month of October. We will be researching them and creating Tombstones, ghostly figures, skeletons, etc. to decorate the room with. The last week of October the kids will bring in a pumpkin and decorate the pumpkin to look like an explorer of their choice. As they decorate I thought they could give clues as to who their person is and at the end we will guess their explorer. Sort of like a chalk talk using pumpkins. Then they can take the pumpkins home to decorate their house or throw away. Just an idea!
I have the kids make a diorama of a haunted room. They usually do it at home and their families love to get involved. Then I thumbtack the boxes to a bulletin board in the shape of a rectangle. I then add a roof line and other details to turn it into a house. The kids love it and it gets lots of comments from others in the school.
The students can use white q-tips (whole and cut up) to create a skeleton on black construction paper. They can draw the head themselves with white chalk or crayon, or you could provide a skeleton head clip art.
