Elephant Toothpaste Elephant Toothpaste Hi! I'm a 5th grade teacher and I'm wanting to help some of my students make the elephant toothpaste activity into a Science Fair type project. I'm wondering what would be the best way to measure the height of the reaction. I'm also wondering if you have any other variables that you could change other than the type of container or the strength of the peroxide.

HELP! Butene or but-1-ene? HELP! Butene or but-1-ene? As part of my project, I need to explain why we use the name but-1-ene instead of butene, although they have the same organic structure. How do I explain why but-1-ene is chosen? Thank you!! Re: HELP! Butene or but-1-ene? Hello there, It's worth doing a little bit of your own research for this to have a more complete answer, but long story short: "but-1-ene" is more specific than "butene." But-1-ene is one version… Read more
Kidney stone project Kidney stone project Hi! For my science fair project, I want to simulate the effects of Flomax compared to natural alternatives in breaking a kidney stone. For the kidney stone, is it simple to make calcium oxalate crystals? If so, how would I go about making them? If not, are there any alternatives I can use instead to accurately simulate the process of the kidney stones breaking? I have read an article where they used calcite crystals, however, I do not know if that… Read more
