which has more energy a pecan or a peanut?**
 * Experiment:

calories--are the what is made into fat and food energy amount of calories in pecans/peanuts how to test for calories
 * Background Research**

 * Materials**:
 * A small bag/can of unsalted, shelled peanuts
 * A cork
 * A needle
 * A large metal juice or coffee can
 * A small metal can (like a soup can) with paper label removed
 * A can opener
 * A hammer
 * A large nail
 * A metal BBQ skewer (like the kind for kabobs)
 * About a cup of water
 * A thermometer
 * Some matches or a lighter
 * A piece of paper and pencil to record your observations

1 Carefully push the eye of the needle into the smaller end of the cork. 2 Remove the two ends of the large juice can with the can opener. 3 Using the hammer and nail, have an adult punch holes around the bottom of the large can. These are air holes that will make the can act like a chimney and will contain the heat energy focusing it on the smaller can. Then gently push the pointed end of the needle into a peanut. If you push too hard the peanut will break. If it does, use another peanut. It's also better to have the peanut at a slight angle.
 * Procedure**:


 * Hypothesis**: A pecan will burn hotter and longer than the peanut because the pecan is dryer.


 * Conclusion**: The pecan burned for 2 minutes and 20 seconds and. its highest height was 8 centimeters and the peanut burned for 1 minute 55 seconds and its flame height was 4 centimeters and tells me that it can sustain a flame longer than a peanut
