The two main variables in an experiment are the independent and dependent variable. An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment. The dependent variable is 'dependent' on the independent variable. As the experimenter changes the independent variable, the effect on the dependent variable is observed and recorded. For example, a scientist wants to see if the brightness of light has any effect on a moth being attracted to the light.

Have a question regarding the ribs cooked today. This was the first cook on the Traeger Texas for ribs since I purchased it. The Traeger was set on 225 and the outside temp was around 40. The controller did a great job whenever I checked to be around this reading.The issue I have is the ribs cooked for 7.5 hours.e: Spare ribs on the Traeger-question.

Secone way, I use 225 setting for 3 1/2 hours, foil for 1/2 hour, remove foil and sauce.
