His experiment, “Does the number of paddles affect the speed of a rubber band-powered boat” demonstrated impressive research and creativity—truly deserving of the top spot!
Winning Project Ideas

    • Rainbow Fire Kit

      “We used this experiment for the 8th Grade Science Fair - testing certain chemicals to make colored fire for fireworks. It worked great, plenty of chemicals to work with. Highly recommend for an engaging experiment to explore chemical reaction, electromagnetic spectrum, and color theory.”

      — Laura K.

    • Electrolyte Challenge Kit

      “Kit was very easy to assemble, all instructions can be read online, provided with detailed pictures. This experiment in particular, in my opinion is one of the best for high school project. Shipment was fast (within 3 days). Would HIGHLY recommend to the others!”

      — Irena E.

    • Sugar Metabolism Kit

      “Great kit that really helped with this year's science fair project. The site gave us great instructions that we printed that were written simply and in depth that my middle schooler could follow easily. Would definitely recommend and will look at other available kits for future projects.”

      — Suzanne W.
