Welcome to blobs.org - science put simply (and with lots of friendly blobs!). For user-friendly scientific explanations, you've come to the right place. Ranging from DNA to the heart, there is a wealth of resources from which to choose, and all in an accessible format designed to cater as far as possible to the most inexperienced of users.

Science?

Sitting in the classroom day-after-day failing to understand a thing the teacher's talking about? Or perhaps entertaining a desire to develop what you learnt at school? It's annoying when scientific subjects just don't make sense. Sometimes it's because there's too many long words; other times there aren't enough clear pictures.

This website tries to solve those two difficulties, integrating colourful illustrations with a friendly tone to make science accessible and understandable. With heavily linked articles to draw the reader to other areas, blobs.org is hopefully very helpful!


Charity?

blobs.org started a few years ago with a scheme designed to help charities make money by using corporations' associate schemes to generate funds at no cost to anyone (except for the big wigs of the companies!) but unfortunately no charity has yet been attached to this project. Until that's sorted, watch this space!
