Features • Made of Plastic and Metal • Design to prove the effect of Thermal expansion and contraction • Great physical teaching aids for teacher
Description The experiment demonstrates the phenomenon of thermal expansion and contraction of metallic and non-metallic objects. This experiment can cultivate students' thinking ability, and enable students to learn a method to explore physical laws. The product is made of lightweight materials, which are pressed at high temperature, protected from moisture and treated with anti-corrosion. Let the steel ball pass through the ring several times to show that the steel ball can pass through the ring at a normal temperature. Heat the steel ball for 3-5 minutes, and then pass the steel ball through the ring. At this time, the steel ball expands due to heat, so it cannot pass through the ring. Let the steel ball cool naturally, and the steel ball can pass through the ring.
