You may already have everything you require if your school or organisation received one of our survey packs.
If not, you can print out a colour copy of the survey pack documents on this page. You'll also need a few everyday items including:
- pH strips (available from most garden centres)
- sachet or small amount of mustard
- sachet or small amount of vinegar

The survey should take you no more than 60 minutes to complete. Don't worry if you are unable to answer all the questions, your results are still valuable to us - even if you didn't find a single earthworm!
