An introduction to the physical and chemical behaviour of water, for teachers.
Includes a suggested lesson sequence.

Students explore the concept of surface tension (cohesion), through an activity.
Teacher notes include a demonstration with a charged balloon and water, and another with bubbles.

Students explore the concept of breaking surface tension through the experiments 'Plummeting Pepper' and 'Racing Fish'.
Teacher notes include two more experiments, 'Floating Paperclip' and 'Colour Chaos'.

Students explore the concept of adhesion (capillarity) by investigating the capillarity of plant fibres.
Teacher notes include demonstrations and further activities; 'Capillarity in glass tubes', 'Twisted paper towel', 'Coloured flower', 'Stains' and 'Minimise your footprint'.

Students explore the concept of accurate measurement using laboratory equipment, with a little assistance from our WASP.

Students review the concepts of cohesion and adhesion by considering some sample scenarios and completing a word sleuth (seperate document).
