Without worms, gardens aren't very happy. Worms do important work in the soil so plants can grow. And they do it all without arms, legs, lungs or eyes! Find out how many hearts a worm has and why you should never leave a worm in the sun. Level Pre-1 readers are aimed at children who are starting to read. Basic language, word repetition and short, simple sentences help kids read with confidence. This project has been made possible in part by the Government of Canada.
