Halloween STEM Challenges are collaborative, brain-busting work disguised as fun! Ghosts in the Graveyard is from Bone Bridge® STEM Challenges and it's all about pulleys.

The basic premise:

Students work in partners or groups against a criteria & constraints list to create a ghost transporter that lifts cotton ball “ghosts” from the ground to the top of a pulley. (For younger students, the teacher will set up the pulley; for older students, the teacher will provide materials and students will include the pulley and attachment as part of their designs.)

This resource comes with a Grapes in the Vineyard version, so you can use this any time of year, without Halloween references.


Note: This is the printable version. If you are in a 1:1 / paperless classroom, you will want to check out the digital option for use with GOOGLE SLIDES (TM) instead.

If you have questions about which version is right for you, please feel free to leave me a question using the product Q&A below.


Materials you’ll need to do the activity are easily modified.

Sample/suggested materials for each student or group:

  • Pulley system (dowel and ~6 ft. of rope). One per class or testing station will do. (See photos in “Measuring Results”)
  • Medium or large binder clip (1)
  • Small paper plates
  • Ghosts (cotton balls or marshmallows)
    • Amount depends on total materials provided, but at least one bag per class will be needed for testing.
    • Can substitute grapes, marbles, etc. for a non-Halloween version
    • If you have the time or an aide/volunteer, draw on ghost faces with a sharpie.
  • String, ribbon, or twine (2 – 3 yards)
  • Scissors


– Markers and extra rope (to make small pulleys at each student workstation)

– Tape (constrain to ~12 in.)

– Cable ties

– Pipe cleaners

– Coffee filters or foil

– Multiple sizes of binder clips

– Single hole punch

– Carabiner (alternate attachment for pulley)


Product includes:

NGSS aligned standards, Grades 2 – 8

Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success.
Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem.
Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions.
Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.
Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.
