Easy-To-Do Experiments to Teach Children about Heat Transfer

Heat transfer occurs in many ways such as using a heat press machine to generate an imprint. Check this out. Educating children about the fundamentals of heat transfer can somewhat be challenging. Many children find it difficult to learn this knowledge through textbooks only that is why it is vital for schools to teach via experiments that are fitted to the children’s level of understanding for them to have a better grasp of what and how heat is transmitted. There are numerous inexpensive experiments that can be done or conducted promptly.

Here are some experiments that can effectively teach the concept of heat transfer

Conduction is the transfer of heat energy from materials that have a greater temperature to materials that have a lesse temperature through heat conductors. One example of conduction is when you cook food using a pan. Heat is transferred to the pan, then transferred to the out layer of the food to the inside.

  • The Coin Conduction Experiment. This is a simple test that makes use of coins to teach children about heat conduction. Position six coins on an even surface, this will symbolize atoms. Toss another coin in the direction of the set of coins. The coin tossed symbolizes an atom with extra kinetic energy. Notice what happens to the other coins, this reaction signifies a transfer or transmission of kinetic energy. This is a similar concept that can be observed and realized in heat conduction.

Heat transfer in the convection method is transmitting heat through movement produced within a liquid. As the fluid warms and becomes hotter, it begins to rise and become less dense. On the other hand, the cooler and denser substance sinks under the effect of gravity, which therefore results in heat transfer.

  • The Sunlight Conduction Experiment. This experiment is not difficult to prepare and can well explain to children how sunbeams can be absorbed in liquid to produce energy. Fill up a basin or a bowl with cold liquid. Let the children feel the water. Afterward, position it under a sunny location and leave it there for two hours. Ask the children to feel the liquid’s change in temperature. The warming of the liquid is the result of it absorbing sunlight.

Radiation. When heat is transferred through radiation, this is known as radiant heat and doesn’t essentially need a channel to carry or move it.

  • The Radiation Experiment. Explaining to children the basics of heat transfer by radiation can be performed without difficulty and out of harm’s way. Lead the class outdoor and position them in a shaded area. Ask them if they feel hot or cold. Then, position them under the sun and ask the same question. The warmth felt under the sunny location symbolizes radiation which can be understood as a succession of waves given off by the sun which heats the ground.
