Notes SPI 0807. Inq. 1 B 0807. Inq. 1 Dependent Variables (Variables and Controls) Science Tennessee SPI Objective: Design a simple experimental procedure with an identified Instructions for Students (dependent variables) control and appropriate variables. 1) View this Power. Point presentation in slideshow mode. 2) You can find instructions about how to do this by doing a Essential Question(s) Google or by searching You. Tube. 1) Whatsearch are dependent (responding) variables? 3) you it in slideshow mode, pressfrom the right-arrow 2) After How is anhave independent variable different an keyboard button to advance through the presentation. dependent variable? 4) If you need help, please communicate with your teacher. Check for Understanding Design and conduct a simple experiment that includes an independent variable, and controls.

What is a Dependent Variable? Ø Often called the "responding variable" because it is the response to the previously introduced independent variable. Ø …is the result that you observe after you introduce the independent variable. Ø In other words, first you introduce the independent variable, and then you observe the response which is called the… Dependent Variable Also called "Responding Variable"

Example: A scientist is conducting an experiment to test how sunlight affects plant growth. Ø She places one corn plant 1 meter away from a sunlamp. Ø She places one corn plant 2 meters away from a sunlamp. Ø She places one corn plant 3 meters away from a sunlamp. Corn plant 01 Corn plant 02 Corn plant 03 The independent variable is the distance from the sunlamp What is the dependent (responding) variable in this example? Hint: What is the response to the distance from the sunlamp? Dependent variable is the plant growth

Example: A student conducts an experiment. He uses three types of sour candy. He gives one piece of candy to each participant and records their facial expressions to estimate how sour each candy is. The independent variable is the type of sour candy What is a dependent (responding) variable in this example? Hint: What is the response to the different types of candy? Dependent variable is their reaction (facial expressions)

Example: A student uses three types of Elmer’s glue to determine which type has the strongest bond when gluing two pieces of writing paper together. She places 2 grams of glue on each sheet and then measures how much force it takes to pull them apart. Liquid-washable Trial 01 Glue Stick-washable Trial 02 Glue Stick-nonwashable Trial 03 The independent variable is the type of glue What is the dependent (responding) variable in this example? Hint: What is the result from using the different types of glue? Dependent variable-how much force to pull apart the paper
