Heat Output of Diesel, Kerosene and Biodiesel in Smudge Pots

Purpose The purpose of this experiment was to compare the heat output of diesel, kerosene and an alternative fuel source in orchard smudge pots. I became interested in this idea when I was watching the news and it reported on rising diesel prices, I wondered if there was a cheaper and more efficient fuel for diesel-powered items, like vehicles or heaters. The information gained from this experiment could help people with an orchard....

Colourful convection currents

Articles Required: Three tablets of water colours, hard-glass jar. When you heat water, only a part of it comes into a direct contact with its container which is being heated. But strangely enough, the tempera­ture of entire body of water rises uniformly. So, it means that the heat absorbed by the container spreads equally throughout the entire liquid. The most interesting fact about it is that this process of heating is not haphazard and takes place in a very systematic manner. You can witness it through the experiment...

Coiling Liquids Science Experiments

Introduction :- :- Have you ever noticed how your chocolate syrup coils when you pour it on your ice cream? Or how the soft ice cream doesn't just fill your cone up like water would, that it forms large loops instead? Our hypothesis is that it is due to the thick nature of these liquids. They belong to a group known as "thyrotrophic" liquids. That is, they are liquids because they are not solid, but they are, in some cases, incredibly...
