Abstract

In this Activity, students determine how many calories are released per gram when marshmallows and cashews burn and then compare the quantity of energy available from carbohydrates vs. fats. Students burn the food items beneath a metal soft drink can containing water and measure the resulting change in temperature of the water. This Activity can be used to introduce calorimetry, or as an investigation of types of food molecules.

  Abstract:
  The concept of density represents a treasure trove of demonstrations, experiments, and discrepant events. Shortly after learning about common units of measurement, students frequently learn about density as an intensive physical property. The combination ...

  Journal of Chemical Education 2009 86 (2), p 224A
  Abstract:
  This activity makes use of the Ideal Gas Law to determine the mass of a helium-filled Mylar balloon, if it were empty. The concept of buoyancy is explored as weights are attached to the balloon to bring it to neutral buoyancy, at which point the mass of ...
