Eric Warren SIMS 307: Systematic Innovation Homework #4 – Using a Small Set of Operators Consider the following problem formulator diagram. It describes the problem of how an object puncturing the radiator in your car (the thing holding the water for the cooling system) causes the water to run out so it cannot circulate through your engine and remove the heat. This allows the heat to build up and damage your engine. Below are several I-TRIZ operators. Each operator gives you a hint about some

sweeter than sugar. On its own‚ it is said to have a metallic taste so it is often combined with other sweeteners. It is good for cooking and can add the sweet taste to cookies and cakes. Acesulfame potassium - It is almost 200 times sweeter than sugar. It can be used in baking and cooking and there have been no claims against it causing problems.

ELECTRICITY (CLASS – X) QUESTIONS FOR PRACTICE 1. State the law that governs the strength of the current passing through a metallic conductor when a p.d is applied across its end. Illustrate this law graphically? 2. Why is an ammeter connected in series and voltmeter in parallel in a circuit? 3. In an experiment the current flowing through a resistor and potential difference across it are measured. The values are given below. Show that these values confirm Ohm’s Law and also find the resistance

reaction of Iron with Copper(II) Sulfate Purpose: In this experiment we will use stoichiometric principles to deduce the appropriate equation for the reaction between metallic iron and a solution of copper (II) sulfate. This reaction produces metallic copper‚ which is seen precipitating as a finely divided red power. Materials: Flask beaker Copper solution Balance Hot plate •150 ml beaker •1 gram of iron power •30 ml of CuSO₄ Procedure:

Flame Tests By: Jordan Anthony‚ Zack Balog‚ and Evan Degraw Regents Chemistry class‚ Union Springs High School‚ 4th period January 19/2015 The purpose of this lab was to see what colors are characteristic of particular metallic ions in a flame test and use their characteristic color to identify other elements. Another purpose is to understand how fireworks work. This experiment will help one understand how a flame test is performed and that every metal has a unique bright

Caribbean man who wakes up every day in London‚ dreaming he is in the Caribbean. The poem is written in 3 main stanzas‚ with the final line being separate to the 3. There is no definite rhyme except for the occasional couplet for example ‘of grey metallic soar’ followed by ‘to dull north circular roar’. This occasional rhyme helps the poem become more typical of the poetic style and allows the poem to be more easily read. The poet writes in a laid back manner‚ with no use of punctuation which allows
