List the two variables that ultimately determine the method of cooking, when a food item is fully cooked to its appropriate internal temperature.

Scenario 1A chef is trying to figure out if adding salt to the top of their lasagna will change how fast cheese melts.They put four lasagnas, with different amounts of salt, into the oven at 180ºC. They then timed how long the cheese took to melt on each lasagna.Question 8SavedIdentify the independent variable.Amount of saltOven temperatureTime to melt the cheeseType of cheeseI'm not sureQuestion 9SavedIdentify the dependent variable.Amount of saltOven temperatureTime to melt the cheeseType of cheeseI'm not sureQuestion 10SavedDetermine a testable hypothesis for this investigation.Scenario 2You are setting up an investigation to answer the following testable question:Does the water temperature affect the time it takes to boil an egg?Question 11Identify the independent and dependent variables. Independent variableDependent variableQuestion 12SavedDetermine a testable hypothesis for this investigation.Question 13Identify two controlled variables and explain why they need to remain the same.Controlled variableReason for control
