JECOMPRIS School Supply Physics Experiment Material Solid Metal Thermal Expansion Contraction Demonstrator

Package List 1 x Set of Physical Teaching Features – Size: About 23.00X4.50X3.00cm/9.04X1.77X1.18in light – Color: As Shown apparatus – Material: Plastic, and magnetism experiment kits – At this time, the metal ball expands due to heat, so it cannot pass through the ring physics laboratory set. – Heat the metal ball for 3-5 minutes, and then pass the metal ball through the ring ring and ball science. – Design to prove the effect of thermal expansion and contraction aerogel. – Let the metal ball pass through the ring several times to show that the metal ball can pass through the ring at normal temperature elementary equipment. – Great physical teaching for teacher physics demonstration equipment. Goods Information thermal expansion experiments tools This physics experiment material is made of material, which is and lasting for use.experiment accessory Let them learn physics with happy.science It can exercise students’ ability, train their observation capability, thinking and analytical skills
