In order to participate in the Massachusetts Invention Convention, there are certain restrictions and requirements.

All inventions must have an associated 4-6 minute video (3-6 minutes for K-2nd) created according to the guidelines Create Your Video.  Also, each student must submit documentation associated with the invention, including the Invention Log or Journal, and the Virtual Display Board slidedeck. The video and invention documentation must be submitted through the registration system no later than March 26th in order for a student to participate.

Here is the rubric to help you in your process. 

In summary, this is what must be submitted to complete an entry into the Massachusetts Invention Convention:

• Remember that animals are not allowed at in-person Massachusetts Invention Conventions; however this year since your submission is purely virtual if you made an invention for your pet you may include your pet in your demonstration video, and of course you can include photographs in your virtual display board. 

• Keep the cost of your invention under $50. Using recyclable materials and repurposing safe materials is fully acceptable and encouraged.

• (For in person Invention Conventions Only) The display board must be no larger than 24”’ with the wings folded in. However, this year due to our online event please follow the guidelines provided above.CAM_8406.png

• Each inventor must have a COMPLETED, SIGNED Invention Log.

• The invention does not have to be a working model, but the inventor needs to be able to explain how it would work. If it can be operational, it should be.

• Inventors may not use lighters, matches, candles or any other open flame or heat source or anything material or liquid considered combustible.

• Inventions may not contain biohazards or utilize any materials that are, or could become dangerous.

• Other restrictions include: electric stun guns, martial arts weapons, guns, replica guns, ammunitions, fireworks, knives of any size, mace, pepper spray, or any device or substance in which the original purpose is to harm or maim. 

• A note on choosing a category: When registering, inventors are asked to select a category for their invention. The categories are used as broad descriptors to help judges recognize inventions in different spaces.  Many inventions fall under multiple categories, in fact, most do. The inventors know their invention best and should choose the category that best describes it.  


Ignite the spark of invention and entrepreneurship in your students and set them on a course to shape a better future.
