conductivity of different solutions

electricity will go though the water but the light bulb will not go on so we will add things like salt, vinegar, lemon juices, soap that is just four things but we will do more than that to see if the cerent going though is good to turn on the light bulb

I think that when the current runs through the water with nothing added to it, will not light up but when there are more conducive things in it the light bulb will go on


We got most of our research from electro boom and from lots of videos on YouTube my dad also helped us out with some of the planning going through the idea. When we were researching the ideas that we found out more like ingredients that we could put into the water to make the light bulb turn on and some ingredients that didn't work so much.


Are variable in our science project was the solutions that we were putting into the water to test if they were conductive or non-conductive This was the main thing that we changed during our whole thing everything else stayed the same fries just me the same amount of current and Visa same light bulb same bowls


we will be adding stuff like salt and different liquids to the water to see how much we need to put in to turn the light bulb on. and we will Meijer the resistance of the water and Meijer the current going through the wires


I observed that when you put the salt in the water the light bulb lit up beacause it is conductive  and a lot of current was running threw the water.But when we tried it with other things like lemonade powder it was not conductive and there was not that much currency going through the water 💧.


We are trying to measure the conducktivety of different solutions to measure we user a mutimeter



In conclusion for us doing the solution conductivity testing, we found out that if there are more minerals in what we are putting in the water it has more current going through which makes it easier for the light bulb to turn on.


we will be applying different solutions to test each one are more conductive

Sources Of Error

-We found out that we had to use DC current instead of AC because we needed more power to turn on the light bulb 

- Also when we went to go shopping for our project we forgot a few things but we still made it work 


I think this project was really fun and a good thing for others to learn in the future.  it is a good thing to know the conductivity of different solutions one it shouldn't hurt to learn new things 2 give things  I try 3 And if you are in the bathtub and you get electrocuted you should not be bathing with salt so you'll probably be fine yeah.
