An oxygen generating apparatus for education is provided to improve the utility by generating oxygen by using peroxide and manganese dioxide and verifying the amount and pressure of the oxygen by using a balloon and a fan. An experiment stand has vertical frames and horizontal frames horizontally installed between the vertical frames. A peroxide supply unit(20) is installed on the upper horizontal frame to store peroxide. An oxygen generating unit(30) is installed on the lower horizontal frame to receive the peroxide. An oxygen-level verifying part(40) collects oxygen generated from the oxygen generating unit. An oxygen distributing unit(50) has two valves(51,53) discharging the oxygen and two pipes(57). An oxygen-pressure verifying part(60) is installed to one of the pipes of the oxygen distributing part. A flame experiment part(70) is installed on the oxygen distributing part. |
