First of all The scissors and paper are designed and made of balanced birds by themselves. It is important to explain the principle of the focus and fulcrum by the balance bird. In addition, it also uses bamboo sticks, wire, and nuts to make simple balance teaching aids. Teachers use 13 iron nails and base positions to think about how to stand so many iron nails on the base. First try to let the teachers think about how to place it. Everyone is very enthusiastic about such experiments. Unfortunately The teacher was successful. The professor finally answered the common method of swinging and other special pupils for everyone. Finally, the magnet was used to maintain a balance. In addition to the balanced concept and the concept of magnetic lines, the teachers also expressed a lot of benefits. At the end of the event, the aluminum can in use in life, add water to present as long as the center of gravity and the fulcrum are correct, how to place it will stand up.
