Coloca los cables a través de la ranura y cierra cuidadosamente la placa de Petri. Es importante que permanezca cerrada para que el reloj no se moje. Ranura para los cables Prepara la "fuente de alimentación" con cualquier fuente de energía natural que desees. ¿Qué combinaciones hacen que el reloj funcione durante más tiempo? Anota tus conclusiones en la siguiente tabla (como en el ejemplo): e.g.: ELECTRODOS MATERIAL SOLUCIÓN HORA DE INICIO FECHA HORA DE FINALIZACIÓN FECHA Cobre y zinc limón detergente 08:00 h jueves 12/1 11:46 h domingo 15/1 Comprueba si tienes suficiente electricidad observando si se enciende el LED. Recuerda que el LED sólo funciona cuando esta conectado en la dirección correcta. La misma regla sirve para el módulo de reloj. Cuando consigas encender el reloj, abre la placa de Petri y verás dos pequeñas placas de metal en el dorso del módulo de reloj LCD. Son para ajustar la hora como en los relojes LCD o de pulsera. Mira el módulo LCD desde la parte de atrás. El contacto del lado derecho es el contacto de modo. Púlsalo y el modo aparecerá. Púlsalo dos veces y aparecerá el número 12: A. El contacto del lado izquierdo es para ajustar la hora, pulsa el contacto de modo y después el contacto ajustado para fijar los minutos. Al terminar, cierra cuidadosamente la tapa de la placa de Petri. Usa un clip o un bolígrafo para ajustar la hora VISTA POSTERIOR DEL MODO DIGITAL Usa un clip o un bolígrafo para cambiar el modo Recuerda: si el reloj se para, tendrás ajustarlo de nuevo. 3 Experimento 5. La lámpara o reloj de limón Equipo: Electrodo de aluminio. Electrodo de latón. Electrodos de cobre. Electrodos de zinc. 3 – 4 limones. Sigue experimentando con varios tipos de "lámparas" y relojes. Podrías fabricar una lámpara de limón, como en este ejemplo. Zn Zn Cu Cu Zn Cu EL RELOJ DE LIMÓN Zn Brass Cu Brass Este experimento como casi todos, sólo funciona si los cables hacen contacto PERFECTAMENTE con todos los electrodos. Si uno no hace contacto, el LED no se enciende. Asegúrate de que los cables y los electrodos están perfectamente limpios. Si hace falta, inténtalo añadiendo otro limón y otro par de cables. Asegúrate de que los limones son jugosos. Si es necesario, añade agua. Al Al
(EN) Produce your own clean electricity! Using just the energy of a lemon and this kit you can make a clock work. Enjoy science! WARNING: Certain experiments require adult supervision. Be careful when using parts with sharp points or edges. The Magnesium ribbin included in your kit is highly flammable. Do not use this material in any way other than described in the experiments! Keep it away from any source of heat. If for any reason this material burns, DO NOT INHALE THE FUMES! PARTS LIST Experiment console ● Electrodes- Magnesium strip ● Electrodes- Aluminum ● Electrodes- Brass ● Electrodes- Copper ● Electrodes- Zinc ● Electrodes- Carbon ● <strong>Clock</strong> module ● Led ● Wires ● Rubber (latex) tube ● Plastic tube ● Steel wool ● pH paper (indicator paper) ● Funnel ● Instruction manual ● Measuring spoon ● Paper clip ● Polystyrene square ● One and a half volt (1½ V) AA batteries required (not included) ● Certain household substances required INTRODUCTION This kit is called “Nature´s Electricity” because it shows how electricity can be produced from several materials containing chemicals that react when they come in contact with various metals, just like a battery. A battery is made of Zinc and a Carbon rod, which are placed between a chemical paste. When you make your own natural battery, the same process occurs as in the ordinary batteries you are familiar with. The electric current flows because a chemical reaction takes place between the metals and the acids in the vegetables, fruits, soaps, etc. In some experiments, you may find that one piece of fruit, such as a lemon, can produce lots of electricity, enough to light up a LED or the clock module. In other cases, you may have to use 3 or 4 or even more pieces of fruit to get good results. This is very much the same as with batteries. In certain cases, 1 battery will be enough, and in others, you may need 2 or 3 or even 4 batteries. THE EXPERIMENT CONSOLE 1 Wires from clock 2 Test tubes 3 Petri dish lid with LCD clock module already in place 4 Small test tube 5 Rectangular container 6 Wires from clock 7 Rectangular container 8 Test tubes 9 Legs to stand console upright (Snap in place) 10 Petri dish lid with LCD clock module already in place 11 Small test tube 12 Top console cover Preparing the electrodes Become familiar with the parts of the experiment console. Be very careful when handling the clock module. Keep the petri dish covered so that the clock will not get wet. Abbreviations You will use electrodes made from various materials. Chemists use recognised abbreviations for most of these. Aluminium al magnesium mg Iron fe zinc zn Carbon c copper cu Test tube t.T. Note: the carbon electrode is black, the aluminum one is shiny silver, and the zinc electrode is a dull greyish silver. The magnesium ribbon is similar in color to the zinc electrode, but is thinner and has no holes. Caution: this activity must be performed with adult supervision. Be very careful when slicing the rubber and plastic tubing! Your kit includes rubber and plastic tubing. These need to be cut into pieces about 1/4 of a inch (6-7 mm) lengths. Each cut piece should look like this: Cut the tubing very carefully with a good pair of scissors. These pieces of rubber and plastic are necessary to attach wires to the electrodes. Preparing carbon electrodes Step 1 : take a slice of the rubber tubing and slip it over the carbon electrode. 4 Step 1: Carbon electrode with rubber slice Step 2 : take a wire and push its exposed end into the rubber tubing so that touches the carbon. Step 2: Insert exposed end of wire into rubber slice Step 3 : bend the end of the exposed wire upwards to prevent the wire from pulling out. Step 3: Bend exposed end of wire over rubber slice PREPARING MAGNESIUM ELECTRODES WARNING: The Magnesium ribbon included in your kit is highly flammable. Do not use this material in any way other than described in the experiments! Keep it away from any source of heat. If for any reason this material burns. FLAMMABLE DO NOT INHALE THE FUMES! Divide the Magnesium strip into Thumbtack three parts, and cut careflly with a pair of scissors. Each piece should be about one inch (33 mm) long. On one end of each of the Piece of magnesium Magnesium electrodes, pierce two holes as shown in the illustration. Use a thumbtack very carfully to do this. Exposed end of wire Thread the exposed end of one threaded through piece of of your wires through both magnesium holes as illustrated. Cover the wire and Magnesium strips with the rubber tubing. Now your Magnesium Wire and magnesium covered electrode is also ready for use. by rubber tubing Preparing All Other Electrodes For the Zinc and all other electrodes, use the plastic tubing. Use it in the same way as explained and illustrated above. NOTE: The two kinds of tubing serve three important functions: a) Like an elastic band, the tubing holds the wire to the electrode, ensuring good electrical contact. b) It shields this contact from unnecessary contamination. c) It helps to prevent one electrode from touching the other, when both are immersed, one above the other, in the same test tube. The drawing here shows you how to use the LED attached to electrodes.
