According to the American Heart Association, adolescents in middle school should be eating approximately 1,600 calories a day and only about 30% of these calories should be coming from fat. With this knowledge, the students examine 7 popular snacks to see how they fit with the AHA standards- what percentage of the calories comes from fat. This activity is shocking for the children! They discover that what they think is healthy, really isn't fitting the AHA standards.
This activity not only give the students a a "real life" application of solving for percentages, but also ties in a health/science lesson.
