The class began with an introduction by MHI Group employees to the products manufactured locally at the Mihara Machinery Works. This was followed by a talk by a guest speaker from the NPO Kodomo Uchu Mirai Association (KU-MA) to arouse the students' curiosity toward space and their sense of adventure. He explained the principles that enable a rocket to fly in terms the students could easily understand.
Next, the students took up the challenge of making "syringe rockets." Working in groups, the children considered what they should do to make their rocket fly higher and straighter, and they proceeded to devise various ways and enjoyed experimenting with them.
Finally, the children watched an experiment, conducted by one of the instructors, using a plastic bottle filled with water. Air was inserted into the bottle gradually, until ultimately the pressure caused the water to gush out. The children let out squeals of surprise seeing the power wielded by air.
Going forward, MHI Group will continue to convey the fun of science (and science classes!) to children through monozukuri as our way of developing the next generation and contributing to our local communities.
