Workshops
AHHAA workshops open the door to the nuts and bolts of the world of science.
Occasionally we still wonder why soap washes our hands clean? Or why it hurts to put your hand on a hot stove? What really happens in a test tube when substances interact to cause an explosion? Are all bacteria bad? What is blood pressure? Do I have high blood pressure and what is it for?
AHHAA workshops are an exciting way to immerse yourself in the world of science and experience it through a magnifying glass. The workshop programme is designed to stimulate all five senses!
Intriguing discoveries, exciting tests, explosive experiments and knowledge-based explanations are just part of what AHHAA workshops have to offer.
