Chapter 5 Outline •Sensation is the detection of physical energy from the environment which weencode as neural signals. •When we organize and interpret our sensations‚ it is known as perception •The beginning level of sensory analysis is also known as bottom- up processing •Top-down processing is the information processing guided by higher-level mental processes‚ as when someone constructs perceptions drawing on our experienceand expectations. •Bottom up processing is sensory analysis that begins

Unit 3 The Characteristics of Electricity ( pg 296 ) Day 1 Electrostatics - study of static electricity Neutral objects - materials that do not carry a charge Conductors allow charges (electrons) to flow through them easily. E.g. metal Therefore no matter how hard that you rub a metal tap no static charge will build up because the electrons that you are giving the tap just keep on moving up the tap and down the water line until they reach a ground. Insulators do not allow charges

A sloping surface‚ such as a ramp. Makes lifting heavy loads easier. The trade-off is that an object must be moved a longer distance than if it was lifted straight up‚ but less force is needed. Examples: Staircase‚ Ramp Lever: A straight rod or board that pivots on a point known as a fulcrum. Pushing down on one end of a lever results in the upward motion of the opposite end of the fulcrum. Examples: Door

energy relates to electrical energy Materials and Method In order to complete this experiment we used a combination of electrocalorimeter (immersion heater and calorimeter)‚ power supply‚ ammeter (0 to 3 A)‚ voltmeter (30 V)‚ rheostat‚ connecting wires‚ thermometer‚ stopwatch‚ laboratory balance‚ and ice. In order to obtain the data‚ the DataStudio™ software is set up on the computer to use the temperature sensor on the apparatus to collect steadily the temperatures at specified time interval

Automotive engines have gone through tremendous changes since the automobile was first introduced in the 1880s‚ but all combustion engines still have three requirements that must be met to do their job of providing power – air‚ fuel‚ and ignition. The mixture of air and fuel must be compressed

with aluminum foil. The electroscope is a simple instrument that can help detect the presence of static electricity. If a glass rod were rubbed with a piece of cloth then placed near the ball‚ the ball will be attracted to the rod. After a few seconds of contact with the rod‚ the ball will be repelled. Why? If a plastic rod were rubbed with flannel or wool‚ and the rod placed closed to the ball‚ the same result will be observed. Both the silk and woolen pieces of cloth also show signs of having been
