A College student is snacking on chips while watching television.

Why might he consume a larger portion of chips if not the whole bag, than he plans to?

The label on the bag says that a serving consists of about 20 chips. The bag contains 11 servings, and each serving provides 150 Calories.

If the student eats half the bag (half servings), how many Calories will he have ingested?

How might he moderate his portion size without counting every chip he eats?

What activity might he do to burn off those calories ingested?
