Identifying Dependent and Independent Variables Instructions: For each of the following research designs‚ identify the dependent and independent variables. 1. To investigate the effects of exercise on mathematical problem-solving ability‚ a researcher assigned subjects to one of two groups. One group did 50 jumping jacks and the other group did 200. After exercising‚ both groups did a set of math problems. 2. A researcher hypothesized that talking to plants enhances their growth. To test her hypothesis

pedagogical model comparison project will center round elementary literacy‚ which includes pre-kindergarten through fifth grade. Pedagogy‚ as defined by Watson and Wildy (2014)‚ is the “set of instructional techniques and strategies which enable learning to take place and provide opportunities for the acquisition of knowledge‚ skills‚ attitudes‚ and dispositions” (p. 83). It is important to recognize that literacy acquisition in the early elementary grades focuses on children learning the foundational

Experiment 3: Solution Calorimetry: Thermodynamics of Potassium Nitrate II. Abstract A determination of thermodynamic variables of KNO3 is presented. KNO3 was heated and dissolved in varying volumes of distilled water. Upon dissolution‚ the KNO3 solution was removed from heat and the temperature was recorded once crystals formed. For each solution‚ ∆G the Ksp were found with the temperature and molarity values. ∆H and ∆S were found through the linearization of the data with

What is the SI unit of force? What are the fundamental units of force? 4. Why is force a vector? 5. A chair is pushed forward with a force of 185N. The gravitational force of Earth on the chair is 155N downward‚ and the floor exerts a force of 155N upward on the chair. Draw a free-body diagram showing the forces

later found out that the crown may not have been of pure gold‚ but made of a gold and silver mix. Hiero called in a young man by the name of Archimedes because he was capable of revealing the truth. How did Archimedes use his principle to solve King Hiero’s problem? One day‚ while Archimedes was getting into the bath tub‚ he noticed that the more he walked into the tub‚ the more water that ran out of the tub. He found out that when an object is immersed under water‚ there is a volume

Variable Geometry Turbocharger Turbochargers works on the simple principle of increasing the intake air density by compression. Being able to fill more air into the combustion chamber will allow more fuel to be added to produce more power. However the operation of the turbocharger relies solely on the exhaust gas velocity to drive the compressor. Thus the compressor will be at optimum operation range when the engine is under heavy load. When the throttle is opened‚ it will take a certain period
