Investigating airflow over shapes
By the end of this activity, students should be able to:
- describe how airflow separation affects drag
- test different shaped objects using a hairdryer and pieces of thread to find where airflow remains attached and where it becomes separated
- identify shapes that create the least separation and relate this to which shapes will have the least drag.
