Building Science concepts through real experiences.
If LPG is an odourless gas, then how do we detect a gas #leakage? Ans. This is not done by adding rotten cabbage or eggs !! Instead it is done by adding a chemical odourant named Ethyl Mercaptan to the LPG Gas. Ethyl Mercaptan, a sulfur compound is a clear…
Earth vs Venus – while they are two planets in our solar system, the former is the third planet while the latter is the fourth planet in the solar system. In addition, the mass of the former is much more than the latter. The latter is very close to the…
In the summer, because of thermal expansions, the electric wires sag, and in the winter, due to contraction, they may break. As a result, when setting up the wires between the poles, it’s important to keep them somewhat loose in the summer so that they don’t break in the winter due…
In this activity, you will make your drawings move around by letting it float on water. What makes this possible is the interesting chemistry of dry erase markers. These markers are usually used to write on white boards or glass surfaces and can easily be erased to make space for…
Soap molecules consist of a hydrophilic (“water-loving”) end and a hydrophobic (“water-fearing”) end. Water molecules are polar molecules that can dissolve other polar molecules. Fat (and oil) molecules are nonpolar molecules, so they cannot dissolve in water. Milk is a mixture of water, fat, vitamins and minerals. When soap is…
Let’s make our own Glider Plane! A glider is a fixed-wing aircraft that is supported in flight by the dynamic reaction of the air against its lifting surfaces, and whose free flight does not depend on an engine. Most gliders do not have an engine, although motor-gliders have small engines…
Elephant toothpaste is a foamy substance caused by the rapid decomposition of hydrogen peroxide using potassium iodide or yeast and warm water as a catalyst. How rapidly the reaction proceeds will depend on the concentration of hydrogen peroxide. Because it requires only a small number of ingredients and makes a…
Sublimation is the transition of a substance directly from the solid to the gas state,without passing through the liquid state. Sublimation is an endothermic process that occurs at temperatures and pressures below a substance’s triple point in its phase diagram, which corresponds to the lowest pressure at which the substance can exist as a liquid. The reverse process of sublimation…
It is the 21st century and children in almost every other household seem to be hooked to electronic devices. From watching shows to playing video games, parents seem to be worried about the number of hours their children spend in front of these devices and are even more concerned about…
Why does it rain? What is a cloud? How do machines work? Is there a difference between climate and weather? These are a few out of many 100 questions that students wonder about every day. Thinking from a learner’s mindset, they want to get out into the field and try…
While the phenomenon of identical twins may sound easy to comprehend, it is extremely important to understand what we mean by the term “Identical Twins” before diving deep into its features and other characteristics. Identical twins, also known as monozygotic, are twins that have been developed from a single egg/sperm.…
