Invention convention ideas

As your students start brainstorming invention convention ideas, you may hear them say they can't think of anything to invent. In invention conventions, students generally develop creative innovations to solve real-world problems.

Annually, more than 100,000 students also participate in Invention Convention Worldwide. Students are ultimately invited to present their inventions at Nationals by way of local contests. Teams of up to four students may participate, and this year's competition will be held virtually. Find your local Invention Convention program here.
