Rice flour as a heat insulator for learning media for students with special needs
The objective of this study was to determine the use of rice flour as a heat insulator for learning media for students with special needs. Experiments were done method by testing rice flour placed on the wall that heat radiated by bulb lamp with various intensities (i.e. 8, 10, and 12 W). The results showed that rice flour is a good heat insulator. This is confirmed by the test results using thermocouple tools showing a decrease in temperature of the insulator testing toolbox. The rice flour caused the heat from the lamp inside the box to be restrained from spreading out completely. The concept of heat radiation and the change of heat adsorbed by rice flour was explained, which can be further developed for learning media for students with special needs. The results of this study are expected to facilitate teachers in providing understanding to students in understanding the occurrence of heat insulators, especially for students with special needs.
