- This heat conduction demonstrator is designed for middle school physics classes, effectively illustrating the differences in thermal conductivity among various solid materials. - The experiment involves heating a heat storage block, which transfers heat through a uniform heat conductor rod. This setup allows students to visually observe how heat travels through different materials by using large rods positioned in a pit to showcase the heat transfer process. - To conduct the experiment, place the demonstrator on a stable surface. Apply butter to the concave surfaces of each heat conductor rod and insert a match vertically into the cavity. Heat the heat storage block with an alcohol lamp. As the experiment progresses, students will witness the matches fall off the rods in succession, highlighting the varying thermal conductivity of the materials. - After completing the experiment, ensure the heat conductor rod is completely cooled before cleaning it. Apply a light oil coating for maintenance and proper storage. Handle the instrument with care to avoid dropping or damaging the heat conducting rod. - This instrument is ideal for teaching practical physics concepts, making it suitable for classroom demonstrations, science fairs, and educational workshops. It provides a hands-on learning experience that enhances student engagement and understanding of thermal properties in materials.
