Question 52
Contribute to a class presentation or display about the work that scientists have done about how smoking affects health. Choose one of these questions, or think of another question of your own about how scientists have found out about the effects of smoking on health. Some have several parts; do not worry if you do not have time, or cannot find information, about every part.
- When did scientists first begin to think that smoking was bad for health? What made them think this? How did they share their ideas?
- What evidence is there that smoking is bad for health?
- What evidence is there that smoking has a negative effect on the development of a fetus?
- How have people responded to this evidence? Has the number of people smoking decreased in most countries? Has the number of women smoking during pregnancy decreased in most countries?
Scientists cannot ask some women to smoke during pregnancy as an experiment. They collect information, look for correlations and publish methods and results so that other scientists can examine them.
