How to create a potato battery

Introduction

• Greeting: Hello, I hope that everyone is having a good morning.
• Attention getter: Did you know that potatoes have another use other then been used to cook with? They have electrical energy! Yes a boring plain potato can be used to give power to a small LED clock.
• Specific Purpose: To inform and demonstrate to the audience how to make an electrical connection using simple materials.
• Preview of the main idea:

I. The materials needed
II. The steps in the process
III. The end result

Body
I. Acquiring materials- The first thing to be done for the experiment is getting the materials that are needed. 4 things are required for this experiment.

A. Material 1- Potatoes- You will need 2 potatoes.
B. Material 2- Nails- You will need 2 copper nails and 2 galvanized nails.
C. Material 3- Wiring- You need 3 different copper jumper wires.

1. 3 different copper wires with alligator clamps.

D. Material 4- Clock- A LED single battery clock is required.

1. Either a single AA battery or single AAA battery clock.

II. Putting the materials to use – The second step is to use all the materials to make the appropriate connections for the experiment to work.

A. Potatoes- You will need two fairly sized brown potatoes.

1. Call one potato A
2. Call one potato B

B. Nails- Each of the four nails will be placed in both of the potatoes.

1. Place one copper nail in one side of each potato.
2. Place one galvanized nail in each potato on the opposite side insuring the nails do not touch.

C. Clock- The clock must be an LED that requires little power to operate and uses only one AA or AAA battery.

1. Make sure that no battery is in the clock, if there is then remove it

D. Wiring- Each of the three wires are important for the electrical connection.

1. Connect the first jumper wire from the copper nail on potato A to the positive terminal on the clocks battery port.
2. Connect the second jumper wire from the galvanized nail on potato B to the negative terminal on the clocks battery port.
3. Last connect the third and final jumper wire to the remaining galvanized nail on potato A and the remaining copper nail on potato B.

III. The outcome- After making all the appropriate connections the clock will have power.

A. Power to the clock- By using potatoes and their ability to release electrical energy through chemical reactions the clock now has enough power to display the time.

Conclusion
• Brake light: Now you know just how easy it is to make power with potatoes.
• Re-state purpose: This demonstration was to inform you how to power a clock using
• Summary:

I. Having the correct materials.

...undertaken to give an overview of the latest findings and statistical data on the issue especially on soil, water and food cycle. The World Health Organization (WHO) recommends a safe limit for As in drinking water of 10 mg LÀ1. A recent survey looked at the As concentrations of drinking water from deep wells in 64 districts in the country and found that 59 had concentrations >10 mg LÀ1 and 43 had concentrations >50 mg LÀ1. Contaminated groundwater is also used for irrigation of paddy rice, which is the main staple food for the population. This practice enhances the level of As in the soils rendering them unsuitable for agriculture. A few recent studies have reported that 85–95% of total As in rice and a vegetable was inorganic, which outlines the need for more studies for standardization. Arsenic concentration is higher in Bangladeshi soils,...

The Power of Packaging

...The Power of Packaging Alice Louw & Michelle Kimber The Customer Equity Company* In recent years packaging has developed well beyond its original function as merely a means of product protection and now plays a key marketing role in developing on shelf appeal, providing product information and establishing brand image and awareness. As packaging’s role in the marketing mix gains momentum, so research into this arena becomes increasingly important. Given the potential for packaging to successfully achieve marketing goals; does research into packaging truly reflects its value within the marketing mix? Do we fully understand the role that packaging plays in a marketing environment and how best to leverage this tool to influence consumers? If packaging is so important, what is the best way to measure its effectiveness? * The Customer Equity Company is a wholly owned subsidiary of TNS (UK) which has been set up to develop the marketing sciences and support brand equity and Commitment modelling worldwide. 1 What is packaging? The definitions of ‘packaging’ vary and range from being simple and functionallyfocused to more extensive, holistic interpretations. Packaging can be defined quite simply as an extrinsic element of the product (Olson and Jacoby (1972)) - an attribute that is related to the product but does not form part of the physical product itself. “Packaging is the container for a product – encompassing the physical appearance of the container and......

Hsc Chemistry Notes

...Chemistry Notes 2010 Core Module 1: Production of Materials Contextual Outline Humans have always exploited their natural environment for all their needs including food, clothing and shelter. As the cultural development of humans continued, they looked for a greater variety of materials to cater for their needs. The twentieth century saw an explosion in both the use of traditional materials and in the research for development of a wider range of materials to satisfy technological developments. Added to this was a reduction in availability of the traditional resources to supply the increasing world population. Chemists and chemical engineers continue to play a pivotal role in the search for new sources of traditional materials such as those from the petrochemical industry. As the fossil organic reserves dwindle, new sources of the organic chemicals presently used have to be found. In addition, chemists are continually searching for compounds to be used in the design and production of new materials to replace those that have been deemed no longer satisfactory for needs. This module increases students’ understanding of the implications of chemistry for society and the environment and the current issues, research and developments in chemistry. 1.1 Construct word and balanced formulae equations of all chemical reactions as they are encountered in this module: • Acid reactions: o acid (aq) + base (aq)  salt (aq) + water (l) o acid (aq) + active metal (s)  salt (aq) + hydrogen......

...-1- DANIEL GOLEMAN’S EMOTIONAL INTELLIGENCE: WHY IT CAN MATTER MORE THAN IQ (1995)1 False facts are highly injurious to the progress of science, for they often long endure. But false views, if supported by some evidence, do little harm. (Charles Darwin, The Descent of Man and Selection in Relation to Sex, 1871)2 Since its publication in 1995, Daniel Goleman’s Emotional Intelligence: Why It Can Matter More than IQ has been the flagship of a fleet of books that Goleman has authored or co-authored, and the foundation text of a world-wide movement that claims that what has been universally regarded as intelligence is merely one type of intelligence – cognitive intelligence – and is not as important as another type of intelligence – emotional intelligence. As the dust jacket of Emotional Intelligence proclaims, it is, “The groundbreaking book that redefines what it means to be smart.” In this document, I will analyze every book and article that Goleman adduced to denigrate the importance of cognitive intelligence, and even more, the tests that measure it. I will demonstrate that not one of them says what Goleman claims it says, and many say the opposite.3 No one denies that emotional strengths and social abilities often contribute to social and occupational success. But Goleman knew two crucial facts about them that he did not tell his readers. In the introduction to Emotional Intelligence, Goleman wrote (pages xi-xii), This mapping [of emotional intelligence] offers a......
