believe that concentration affects viscosity in such a way as that the stronger the concentration of the solution‚ the stronger the viscosity of the solution. Variables Independent variable: * Concentration of C6H12O6 Dependent variable * Time it takes to pour 1cm3 of the C6H12O6 solution as an indirect measurement of the viscosity of the solution Controlled variable Temperature of the solution | Controlled by putting all solutions in a water bath set at 35°C until they have reached

experiment Aim: The aim was to find the effect of holes on a parachute‚ varying their size and number. Hypothesis: 1. By increasing the number of holes‚ the time it will take to the parachute to reach the ground will be longer and its flight will be more balanced. 2. By increasing the size of the hole on the parachute‚ the time it will take to the parachute to reach the ground will be shorter and its flight will be less balanced. Apparatus: - garbage bag (squared shape with rounded angles)

think or act instantaneously. The time required to take action depends systematically on mental and physical processes that precede an overt response. Thus throughout the areas of psychology‚ conclusions about the nature of mind and body have been based onmeasurements of human reaction time. Past uses of reaction time data extend from studies of elementary sensory mechanisms (e.g.‚ Green & Luce‚ 1973) to studies of perception (e.g.‚ Garner‚ 1962‚ 1970). Reaction time has a been a favorite subject of

Experiment No. 1 Word Association Test Objective This experiment aims to determine which type of association test (the free association or the partially controlled association test) will elicit a shorter reaction time and that which will elicit more response word. Review of Related Literature Read (1993) distinguished three types associations on the basis of “preliminary drafting of items”: (a) paradigmatic (“The two words are synonyms or at least similar in meaning‚ perhaps with one being more

Bali Aim: The aim of this experiment was to determine the spring constant “k” of a spring using Hooke’s Law and Simple Harmonic Motion. Theory: Part 1: We know from the theory that the Time Period “T” for any spring that undergoes simple harmonic motion: T = 2π * √ (m/k) Where “T” is the Time Period of the spring; “m” is the mass attached to the spring and “k” is the spring constant of the spring used. After mathematically manipulating the equation to make k the subject of the equation

Palmeri claim that superordinate level advantage is only present at short stimulus presentation times. They suggest that at short presentation times‚ categorization relies more on contextual cues provided by the background‚ rather than actual object information. We aim to find if the superordinate level advantage at short presentation times can be attributed to contextual cues. We compared human reaction times when categorizing bird pictures as containing either an animal (superordinate level)‚ or bird

this is because there will be more downward pull from gravity‚ as the terminal velocity for a paper helicopter is low. Variables: Independent variable will be the mass that we change throughout the experiment. The dependant variable will be the time that we measure for the helicopter to reach the floor. Finally the controlled variables include‚ the helicopter itself. As well as the height from which the helicopter is released. Apparatus: Paper‚ Scotch tape‚ Scissors‚ Ruler Method: Create
