On these pages you'll find illustrated instructions for almost 70 practical investigations, most of which can be used as starting points for open-ended work.
The NCBE's policy is to make all of its publications available free-of-charge, on-line (usually as Adobe Acrobat PDF files).
Printed copies of most NCBE publications are also available for a small price (see 'MATERIALS' from the Web site's front page).
The pages in this 'PROTOCOLS' section contain hints and tips, plus recipes, Web links and additional resources that you won't find in the printed documents.
We always try to use inexpensive equipment and materials wherever possible, and when these items are not readily-available to schools, or available at a reasonable price, the NCBE endeavours to supply them.
