To participate in the Invention Invasion:


You can work alone or as a part of a group, with other Cabot students and/or with Cabot parents. Students in a group can be either from the same grade or from different grades.

What Do I Need To Do?

Each individual or a group should create a hands-on invention or experiment and a poster that explains the scientific principles that make your invention or experiment work. All materials that come to school must be safe. No invention should require access to electrical outlets.

Invention or Experiment –

  • Demonstrating your idea is one of the most important parts in becoming an inventor. For your invention, you can either create your own experiment to demonstrate a scientific principle, or select one from one of the Science webpages.  This page contains links to other websites with ideas for your experiment.
  • If it is too difficult to set up the experiment on the night of the Invention Invasion, set up the equipment used for your experiment, and use the poster to explain how it works. Use pictures, drawings or videos to demonstrate the results of your experiment.
  • The experiment does not have to work; if it doesn’t work, explain in the poster what you expected it to do, why you think it did not work out, and what you could try to make it work if you had more time.
  • Pay close attention to safety when setting up or working on your experiments.


A poster is your way of sharing the ideas of your invention with other people. Use the poster to show results of your experiment and explain the scientific principles that make it work.  Your poster should include the following information:

  • Names and grades of everyone in your group
  • Title of your invention
  • Brief explanation of the scientific principle that makes it work
  • Brief explanation of your results — did the experiment work? If it did not, what could you do differently to make it work next time?
  • Can you think of other places that your invention can be used? How does it help people? Are there other inventions that might be used with yours?
  • Information on posters can be either printed or handwritten.  If you are using information from a webpage, please include the webpage title; if you are using information from a book, please include book title and author
  • Pictures on the posters may be drawn with crayons, markers, or pencils.  Pictures may also be photocopied from a book or downloaded from the Internet; if you do use a picture from another source, please include the title of the book or the webpage from where it was downloaded.

Registration –

You must register to participate in the Invention Invasion.  You can register either online or by filling out an online registration form.  Paper forms can be either sent back via a backpack or dropped off in the Invention Invasion box in the Cabot School office.  Directions for online registration are attached on the next page, along with the Registration Form.  Registration must be completed by Tuesday, March 5th.

Setup –

  • Participants may start setting up at 5:30pm.  Please check in at the Welcome Desk when you arrive.
  • Each participant or group will be assigned to a table that may be shared with other participants.
  • All displays must be ready by 6:00 pm, when the event begins.
  • During the event, make sure that you have enough time to walk around and learn about other inventions.
  • If possible, one member from your group should remain with your display at all times to answer questions from other event attendees.
  • At the end of the event, please take with you everything that you brought, and leave the invention area the same as it was before you got there.

If you have any questions, please email
