5 Best Science Kits of 2026

My Top Picks

The [National Geographic Mega Science Lab](https://www.amazon.com/s?k=National+Geographic+Mega+Science+Lab&tag=thetestedhub-20) was the runaway favorite with fifteen experiments spanning chemistry, geology, and physics. The [Snap Circuits Pro SC-500 Electronics Kit](https://www.amazon.com/s?k=Snap+Circuits+Pro+SC-500+Electronics+Kit&tag=thetestedhub-20) is my pick for introducing circuits, and the kids built over a hundred working projects from a single box. The [Thames and Kosmos Chem C3000 Chemistry Kit](https://www.amazon.com/s?k=Thames+and+Kosmos+Chem+C3000+Chemistry+Kit&tag=thetestedhub-20) is the most advanced option in this guide and feels like a real intro chemistry course. For younger scientists the [Learning Resources Beaker Creatures Liquid Reactors](https://www.amazon.com/s?k=Learning+Resources+Beaker+Creatures+Liquid+Reactors&tag=thetestedhub-20) is gentle, mess-controlled fun. The [4M Crystal Growing Science Kit](https://www.amazon.com/s?k=4M+Crystal+Growing+Science+Kit&tag=thetestedhub-20) is the most rewarding patience experiment I have ever given a kid, with crystals forming over several days.
