scientific inquiry - the ongoing process of DISCOVERY in science; diverse ways in which they study the world, hypothesis - a POSSIBLE EXPLANATION for a set of observations or ANSWER to a specific question, variables - factors that CAN CHANGE in an experiment, independent (manipulated) variable - the ONE variable that a SCIENTIST CHANGES during an experiment, dependent (responding) variable - the variable that changes as a RESULT in an experiment, controlled variables (constants) - the factors in an experiment that STAY THE SAME, controlled experiment - an experiment in which only ONE VARIABLE IS CHANGED at a time, data - the FACTS, FIGURES, and other evidence GATHERED through observations, control group - a GROUP SEPARATED from the rest of the experiment where it cannot be influenced by a change in the independent variable, the person running - The time it takes to run a mile depends on the person's running speed. What is the independent variable?, time - The time it takes to run a mile depends on the person's running speed. What is the dependent variable?, same distance (mile) - The time it takes to run a mile depends on the person's running speed. What is a controlled variable?, amount of water - The height of bean plants depends on the amount of water they receive. What is the independent variable?, height of the bean plant - The height of bean plants depends on the amount of water they receive. What is the dependent variable?, both bean plants - The height of bean plants depends on the amount of water they receive. What is a controlled variable?, the temperature of the air - The higher the temperature of the air in the oven, the faster a cake will bake. What is the independent variable?, the time it takes for the cake to bake - The higher the temperature of the air in the oven, the faster a cake will bake. What is the dependent variable?, the oven, the pan, the cake mix - The higher the temperature of the air in the oven, the faster a cake will bake. What are the controlled variables?, different depths - Students measured the temperature of the water at different depths in Lake Skywalker and found that the temperatures varied. What is the independent variable?, the temperature of the water - Students measured the temperature of the water at different depths in Lake Skywalker and found that the temperatures varied. What is the dependent variable?, the same lake - Students measured the temperature of the water at different depths in Lake Skywalker and found that the temperatures varied. What is a controlled variable?, different ages - Students of different ages were given the same puzzle to assemble. The puzzle assembly time was measured. What is the independent variable?, assembly time - Students of different ages were given the same puzzle to assemble. The puzzle assembly time was measured. What is the dependent variable?, the puzzle - Students of different ages were given the same puzzle to assemble. The puzzle assembly time was measured. What is a controlled variable?,
