This Black Friday, we're a little obsessed with Lego. And with so many great Black Friday deals on science and STEM-themed Lego sets — including the Botanicals range, nature-themed sets, animals, space and more — we wanted to share them with you.

Lego is forever. Modern Lego sets include classic worlds like Lego City, franchise collaborations with beloved characters like Super Mario, and exciting new adventures in Lego Dreamzzz, where shark ships ply the skies.

As Black Friday draws ever closer, I've been keeping a keen eye on the best Lego deals popping up around the internet. Reviewing Lego sets and writing about Lego forms part of my day job at That Brick Site, and I've been collecting Lego for a decade — so I'm putting my expertise to good use to help you save some money this Black Friday.
