Science in our daily life ! (Teacher can translate this live)
Basic science concepts behind few daily applications of science
Cooking: Heat energy is transformed to the cooking vessel in the form of radiation, conduction and convection. After the heat energy is passed the dal and vegetables boil and combine to give sambar, etc., Therefore, physics as well as chemistry is involved. And you also have to add grains, water, salt etc. in correct measurement. Hence maths plays a major role too.
The food which we eat takes many chemical reactions to produce energy like protein, fat, etc and blood. Biology as well as chemistry is involved in this process.
Household appliances:
Mixer / Juicer: It converts the electrical energy into mechanical energy. It uses the principle of centrifugal force.
Refrigerator: Electrical energy is converted to heat energy where cooling takes place.
