Science Project

Today is the Wallace School Science Fair, and here is LA's (Little Avenger's) project: calculating the food energy in a marshmallow!  (She's in 4th grade)

You didn't know that could be done at home, did you?   She built a simple calorimeter like this:

She calculated one marshmallow contained 45 food Calories (the heat released from the burning marshmallow to raise the temperature of 50 ml of water 9 degrees Celsius).

But best of all, LA got to eat the marshmallow.  Yum.
