12 Earth-themed Lego STEM Projects

Build and learn about the environment with these LEGO themed STEM projects for Earth Day!

I love to use colorful, hands-on ways to inspire kids to think about STEM concepts.  And it always helps to fit it to a current event of topic they love to explore too -- like these 18 Ocean STEM projects we shared last summer.

With Earth Day coming up this week, taking some LEGOs outside to build a few of these STEM themed projects seems like a great idea to me! Today's colorful activities include fun ways to learn about earth science, conservation efforts and other eco-friendly behaviors.

Earth-themed Lego STEM Activities

I absolutely adore the cross-over of science & engineering with these LEGO activities!  The kids are just thinking "Cool! LEGOS!" and yet there's so much learning taking place at the same time.

And even better, the LEGO company has announced that they're going to make LEGOs even better by using sustainable materials to create the bricks!  Always love to see innovation like that :)

If you're an experienced builder, the first thing you're going to ask is "What type of bricks do we need?

I'm going to make it easy for you -- improvise! 

That's one of the beautiful things about creating with LEGOs anyway -- building on the fly :)

If you don't yet have a set of LEGOs, we've include a few suggestions along with affiliate links to items we love! 

I would highly recommend starting with one of the Classic LEGO sets -- they come in lots of colors and sizes so choose the one the kids like the most and they'll be more likely to pull it out to play. 

I would also get a LEGO base board if you don't have a lot of room or a LEGO Table (if you want storage too) so the kids have an easy place to build!
