The MHA Science Fair is held annually. It is open to homeschooled students in grades K-12.

Registration for the 2020 Science Fair is now closed.

  • To support teaching science to homeschooled kids
  • To provide a forum for them to share and present the results of their work

The Basics

There are 3 ways to participate in the MHA Science Fair:

  1. Conduct an experiment, using the scientific method, and share your method and results (pre-registration required)
  2. Research a scientific topic of interest and present what you have learned (pre-registration required)
  3. Engineering competition at the fair (NO pre-registration) This activity will be done at the fair by anyone interested.  More information will be posted closer to the event.

Use the appropriate rubric to help prepare for the science fair:

Rubric Experiment grades 4-12

Rubric Research grades 4-12

Rubric K-3

What to expect the day of the Science Fair.  Participants should check in and set up their displays between 1pm and 1:30pm.  Refer to the Science Fair Handbook for details about the displays.  Tell people about your amazing projects!  Check out other students’ projects.  Participate in the engineering challenge.  Judges will come around to talk with you about your project if you wish.  Awards will be given out when the judges have made their final decisions.  Please stay until the awards are announced.

Each year we have an engineering challenge. Our engineering challenge in 2018 was Watercraft from PBS kids. Materials will be provided at the Science Fair, and all entries in the engineering challenge need to be made from start to finish at the Science Fair with the materials provided.  The engineering challenge is free and open to any students who wish to participate.

Judging is available, but optional for grades 4-12 for experimental and research projects. Grades K-3 and older kids who do not wish to be judged will have the opportunity to talk to the judges about their projects and will each receive a participant ribbon.

Each judged entry will require: *

  • pre-registration
  • a project display
  • a brief oral presentation for the judge

Non-judged entries are expected to meet all requirements except the oral presentation.

*More information in the Science Fair Handbook. Both new and experienced science fair participants are urged to read the handbook.

Middle School and High School students who wish to enter their Regional Science Fair must use the Project Rules and Guidelines outlined by the Minnesota Academy of Science. While the MHA Science Fair is good practice for a Regional Science Fair, there is no advancement from our fair to Regional Fairs. High School and Middle School Students who wish to participate their Regional Science Fair should register through the Minnesota Academy of Science.  Participants for the State Science and Engineering Fair are chosen from the Regional Science Fairs.
