Simple Energy Experiments

Introduction to simple energy experiments:
The energy means the capacity to do work. The energy of every object is depends on the work done by that object. If more is the work done by the object then more is the energy in the object and vice versa. There are several types of energy. The work and the energy are the equivalent form of each other so that the unit of energy and the work is same. The energy is a scalar quantity. There are so many experiments based on the energy. Here we discuss some of the simple experiments based on the energy.


Simple energy experiments:


Here first we discuss a water energy experiment. This is one of the simplest experiment based on the water energy, it also gives an idea of power of sun and harvesting by the solar energy in our daily life. The main materials required are large bowl from the kitchen, any clean plastic sheet, a drinking glass, some amount of table salt, any food colour, ordinary tap water and a small stone. Mix the food colour and the table salt in the water. Now place the glass in the centre of the large bowl. Now cover the bowl containing the glass with the plastic sheet. The plastic sheet is little loose on the mouth of the bowl. Now place the small stone at the centre of the plastic sheet so that the stone dip in the plastic sheet and it is exactly above the glass. Now place the whole set up in the sun light.

Here we observed that the plastic sheet and the salty coloured water trap the heat energy from the sun so that the temperature of the bowl containing water increases. Now the result is the evaporation of water from the salty and coloured solution. The water vapour reaches the plastic sheet and then condensed at just below the stone and runs down in the glass. This is the water free from the colour and the salt.


Concluding simple energy experiments:


This shows that how the solar energy works to purify the water and how the plants get the water for the harvesting. Because the solar energy is the renewable source of energy and it is free of cost so we use this method on the large scale to purify the water.
