Home Light Bulb Experiments For Kids
Hello friends, here are a home experiment on a very particular light bulb.As you will see the materials are easy to get.
Materials for light bulb experiment for kids:
- > A battery-pack (4.5 v)
- > Cable (single wire and a 2mm section).
- > A switch
- > A glass jar with a lid including (preferably airtight).
- > Plastilina.
- > A punch or other device that will help us to pierce.
After getting our equipment you are ready, get started to build your light bulb:
Step 1: We will take the top of the glass bottle and make two holes, about 3 cm distance between them.
Step 2: In the holes, we have made in the lid, insert two wires about 5 or 6 inches long. We must remember that the cables were introduced to strip the ends so we can continue our project.
Step 3: Extract it to a piece of wire, approximately 6 inches long, copper inside and give it a spiral (similar to the filament of a bulb). In this step I recommend you to make the spiral will assist her on a nail, nail or something similar.
Step 4: Once you have a spiral shaped, connect it to the bare wire ends of the cover. Here I recommend you aseguréis that the spiral and the cables are connected well, if not your own light bulb would not work.
Step 5: Now put everything inside the glass jar so that the coil hangs by cables, and close the lid. Once you have closed Put some clay in the holes where the wires go on top, so that everything stays tight as possible and seal.
Step 6: After ensuring that the bottle is tightly closed and sealed, connect a cable directly from the bottle to the terminal of the battery. The other wire will connect from the bottle to a switch and from there to the other terminal of the battery.
The upshot would be that when you press the switch to pass current, is when we see that the strand of copper (our thread) gets red hot, which is the principle of operation of a light bulb.
When you are watching the performance of your own light bulb, I recommend that if the filament (coil) takes more than 10 or 15 seconds to melt it is advisable to cut it down the spiral, so that your battery is not discharged too quickly.
