Today we will finish our work for our green badge by writing a letter to Blue Peter.

In your letter you need to write what you have done to help the environment and include pictures.

Once you have written your letter you can post it to Blue Peter (ask for mum or dads help with this). You will need to include: your name, date of birth, home address and postcode.

Then post it to: Blue Peter, MediaCityUK, Salford, M50 2BH.
