Scientific Decision-making

Loading Content

Out:

Personal choices are part of everyday life. Whether choosing what to wear in the morning, what to have for lunch, or which college to attend, our days are filled with decisions. Do we approach decision-making in a systematic and organized way? Perhaps not often enough, particularly when making decisions that affect our health, or that of our family members.

Using examples related to cardiovascular health, the Scientific Decision-making unit helps high school and middle school students learn how to make evidence-based decisions.
