Science fairs for kids have come a long way from showcasing vinegar and baking soda volcanoes. In keeping pace with evolving trends in STEM, technology, and science innovation, kids joining science fairs today can be challenged to work on projects in robotics, software development, AI, and engineering. And that’s not to cast any shade on vinegar volcanoes!

Kids, parents, and educators who attend science fairs, whether at the State, National, or International levels can be challenged to use their ingenuity to build cool projects, flex their problem solving skills, and boost their creative and critical thinking. A lifetime’s inspiration for scientific thinking can begin with a single spark, and events like science fairs for kids are designed by top educators to light the candle of knowledge for the kids of today who will be the scientists of their generation.

What’s more is that in today’s virtual environment, many science fairs for kids take place virtually, offer digital events, or provide educational opportunities for kids alongside in-person science fairs. Join live online science camps this summer to get ready for upcoming fairs, including Quantum Frontiers, rocket camp, space exploration camp, atom secrets, electromagnetism camp, and more.
