How to Bend water with Static Electricity Interesting Electricity Experiments for Kids: In this closed circuit, the free electrons from the zinc galvanic strip move towards the copper strip through the LED bulb and make it light up. As a result, the electric circuit gets closed by connecting alligator clips to the LED bulb. However, the movement of electrons inside the lemons creates an electric circuit and the circuit closes. The positively charged copper strip is more likely to attract the free electrons released from the galvanic strip. To summarize – you don’t get the electricity from the lemon but the electricity is generated based on the chemical reaction that happens between zinc, copper and acidic lemon solution. Once the electrons moves into the copper – they tend to pull couple of hydrogen ions or protons from the acidic solution to reduce them by adding electrons. These positively charged ions from zinc moves in the acidic solution which then collected by the copper. Electrolyte removes electrons from the zinc through an oxidation process. Thats where the acidic solution comes in to play – the lemon juice. This is because Zinc also has protons which cannot move through the wires. But when you connect a cathode with an anode – electrons cannot move freely. In our experiment, the copper strip has more electrons so that will work as cathode. The other electrode which gives up electrons is called anode. The one which attracts more electrons is called cathode. One of these electrodes should have the ability to attract electrons. How do Lemons produce electricity and make an LED bulb glow?įor batteries to work, we need three things 2 electrodes and 1 electrolyte. You can change the direction of the bulb to see positive results. Make sure the LED bulb is also in the right position and connected rightly. Tips: If you fail to see the LED bulb lighting up, recheck all your connections. Make sure you leave some space in between two incisions on each lemon to fix the electric wire. Such that, for a total of three lemons you will give six incisions. And give two vertical cuts about half-inch in length vertically on the surface of each lemon using a sharp knife. Step-1: As a first step, pick three to four fresh lemons and place them side by side intact. Let us learn how lemon fruit generates low voltage electricity. Using this activity, we cannot make a high voltage current. The lemon light experiment is a demonstrative activity to show children about electric circuits and how batteries work. Instructions to Perform Lemon Light Experiment Note: Adult supervision is compulsory if your children are performing this science activity on their own as we are dealing with electric circuits and knife. 1) 3 Fresh Lemons (The more lemons you use, the more power or electricity you can create)ģ) Three Copper strips or nails around 2 inches in lengthĤ) Four sets of electric wires that have alligator clipsĥ) Zinc-coated Galvanized strips or nails about 2 inches in lengthĦ) A sharp knife *Product Links are affiliate links – Your support is highly appreciated
