Brake fluid and school science 6

This Association for Science Education (ASE) publication about brake fluid was developed in association with Shell Chemicals UK Ltd. At the time the company employed about 500 people at its Carrington plant.

The booklet contained guidance for teachers and notes for students. It included activities suitable for students aged 12 to 14.
