How ice cream is made(endo/exothermic reactions). I did it in 4th grade and i was the coolest kid for a month, i made a shitload of ice cream,too.
Grow a flower or something in hydro vs soil with the hypothosis of the Hydro will do better. Or if you can't afford a little hydro setup then do a comparison on them both in dirt but one getting nutes and one on straight water.
WIN. That is so cool even I think you're cool as hell for that I can see now all those lil kids getting hyper off ice cream lol.
Thats a dick thing to say, considering this guy is just asking for suggestions, not for us to do his project for him. gtfo. Ice cream sounds good though dude, id go with that
It was a joke. Is he like your man or something? The guy is asking for ideas for a 4TH grade science project. Can't he think of any on his own?Umm off the top of my head a fucking potato turned into a battery?
You can set up a cheap hydro bubbler from a storage tub lightproofed, a net pot, hydroton, a fish tank air pump and air stone. Total like $20. But the ice cream is obviously going to be a hit with the kids and is easier.
How to make methamphetamines..... But really, go with the icecream. I remember those little science fairs and all the kids would make like batteries n shit and then you'd see a long line behind the icecream stand and everyone loved it. So yeah go icecream.
study the effects of an ounce of steak soaking in diet pepsi for a week vs mountain dew, or somthing.. idfk. lol, volcanos are always cool
I did this on my own just for fun, but you could try using electrolysis to separate the sodium out of table salt, or, even better, lye soap, because the table salt will release chlorine gas when you separate it from the sodium. Might not be an ideal elementary school project because you have to heat the lye soap to a very high temperature(i forget the exact temp) and then pass electric current through it, but its cool as hell, because you can then use the sodium to make "explosions" by throwing it in water You could also try something like making an HCL battery, but once again it involves dangerous materials, so it depends on how much the school will let you get away with. Those are just what I can think of off the top of my head.
