First of all, teachers can introduce the concept of temperature to children by showing the principle of thermometer. Teachers can use different objects, such as ice, water and air. Show the reading of thermometer to children and explain the state and properties of objects at different temperatures. For example, when the temperature drops, water will solidify into ice, and when the temperature rises, water will become gaseous steam.
Then, the teacher can guide the children to carry out simple experiments and deeply understand the concepts of heat and temperature. For example, you can use two cups, pour hot water and warm water respectively, and then let the children touch the surfaces of the two cups and feel the temperature difference between them. Children can feel the difference in heat and temperature by touching cups with different temperatures.
In the course of the experiment, the teacher can also let the children carry out simple heat conduction experiments, such as grasping an ice block with their hands and then letting the ice block gradually melt in their hands. Through this experiment, children can understand the heat conduction process deeply and understand that the heat conduction speed between different objects is different.
In addition, in the daily life of kindergarten, teachers can help children understand the application of heat and temperature through daily activities. For example, when cooking, children can observe the boiling and bubbling of water and understand the boiling point and boiling principle of water. In summer, children can observe the melting process of ice cubes and understand the influence of temperature on objects.
In a word, heat and temperature are the basic contents in children's science education. Through experiments and games, children can learn more about the concepts and applications of heat and temperature. In this process, teachers need to patiently guide and help children explore and learn in practice, and cultivate their interest in science and spirit of inquiry.
