Observacions i context
This exercise can be used to highlight the importance of observing our surroundings in order to detect new needs, as well as to explain how technology helps us solve problems that arise in society. Another cross-curricular topic is how women have always been in charge of housework, an unfair situation that we need to change with our behaviour and the way we relate to others.
We can link Josephine Cochrane's invention to other everyday inventions made by women in the late 19th and 20th centuries: the sewing machine (Helen Blanchard), the hypodermic syringe (Letitia Geer), the coffee machine (Melitta Bentz), the disposable nappy (Marion Donovan), the lifeboat (Maria Beasley), the ink pen (Bette Nesmith Graham) or the windscreen wiper (Mary Anderson).
