15 Fun ideas for Science with LEGO

Here at Science Sparks, we love LEGO®. My children play with LEGO® or DUPLO® every day, and it’s been fantastic for helping them develop fine motor control and logic skills and for learning to read and understand instructions. We use LEGO® for building, making up imaginative stories, and, of course, for experiments and investigations. These are some of our favourite science ideas with LEGO®.

More ideas for learning with LEGO®

We reviewed some great DUPLO sets from LEGO Education recently, and I cannot recommend them enough. I also bought my 7 year old a set of LEGO Education Doors, Windows & Roof Tiles which he hasn’t stopped playing with. They’ve been fantastic for reinvigorating his love for building freely.
