Investigating Science is a course on the scientific process/thinking that drives the STEM-related areas.
It looks at the reasoning and problem-tackling strategy that led to the following things all working pretty well: trains/planes/cars, cancer cures, electricity, sanitation, fertilisers, antibiotics, vaccines, MRI machines, computers, mobile phones, nuclear bombs, genetic modification, coal power, spaceflight and A.I., to name a few.
Learning about modes of thinking that have proved very fruitful in problem-tackling in innovative fields in the past is a great way to start activating higher innovative skills.
If you want to end up in STEM or in science communication, science journalism or science education this stuff is made for you!
If you want to end up in a job entangled with technology and research (like medicine or tech companies), or which requires evidence-based decision-making, Investigating Science is a great add-on for those paths too.
