Your online resources

When you subscribe to Letterbox Lab you get our amazing science kits straight through your letterbox. But the fun doesn’t stop there – there’s so much more to discover online! We’ve collated videos, recipes, extra science activities and curriculum links to supplement the science experiments in your kits.

Before each box arrives you will receive an email containing the code that unlocks the online resources that go with it. We also print the code in the ‘Welcome’ page of each booklet and on the safety information sticker on the base of each box. On newer books the code is also printed on the back of the book.
