Hey guys,
Warning - I am a complete Noob in this sort of thing
I'm developing some information on electronics for my school project. I'm trying to get as much fun, and easy stuff as I can. I will probably need to know a little bit about what is going on, but really the knowledge does not need to be intensive as it's only at a grade 6 level. To clarify, I am not in grade 6. I am actually a university student doing my Bachelor of Education, and am working on this project for my science class. The project involves developing a resource that can be used to show kids some basic concepts about science or society. I choose electricity. In grade 6 students will look at simple things like how it can be created, parallel and series, etc.
My main reason for posting here is to figure out what's going on with my initial testing. I have been looking up some info on building batteries by using differing metals in a liquid. But before I even tried that I was curious if I could get electricity while using similar metals and instead differing liquids.
I started with lemon juice mixed with water in a glass, and water in another glass. I was able to generate 100 mV.
I then tried milk to see if maybe this was in some way related to pH. I didn't really notice any large difference but was still able to generate electricity.
My question is, is there any relation to the chemicals involved that can be used to create electricity in this way? Or am I just noticing the residual electrons/electrolytes moving around between the two chemicals to balance themselves out? Or something completely different?
Also, if anyone has some good ideas, or directions they can lead me to basic electronics and working with energy it would be great.
I am currently looking to see if I can build various home made electronic parts that would be simple to do. For example, a water bottle capacitor. And then figure out if I could put all of these things to use in a make-shift electrical circuit, to perform some sort of work. Ideally i'd be performing more work than lighting a light bulb. In an ideal world I'd be creating so much energy out of simple things that I could do something like run a DIY motor to power a DIY helicopter. Or something equally as cool. I'm trying my best to avoid the two electrodes in a lemon to light an LED as much as I can.
