"Rocket stove (rocket stove), is an application of the principle of improved insulation and chimney effect traditional charnwood stove design, the main structure is the center of the L-type snorkel, which consists of the external cladding insulation materials charnwood when burning firewood, unable fugitive The heat will be concentrated in the bottom of the pan to form a high temperature, accelerating the heating pot also achieve complete combustion and reduce smoke generation. Additionally, formed from incomplete combustion in snorkel vacuum, an endless supply of fresh air will be sucked from the furnace mouth automatically (chimney effect) does not require additional Shanfengdianhuo, fire can remain strong. cooked foods high efficiency, like a soaring rocket, greatly shorten the cooking time, but also reduce the amount of fuel. "diagram below ,
"There are bricks on the following, black, green, nature-friendly, like a rocket."
Again split into three groups, issued under prepared "instructions" to get the kids to read 15 minutes. Ask questions, and share. But children are always charnwood still do not dare to publish. Teacher atrocious, is not accustomed to such a class way, is hard data, is really no problem ....... As a result, when the kids ask questions, the teacher "did not even answer," but is the first to publish a look at the other students, the students of the issues raised for discussion, and then the teacher, or not "serious" answer, is entirely in the fuzzy Under the unclear status, charnwood little understood.
This design, my idea is that in the Internet generation of children who come into contact with "Message amount + amount of data," it is too much, and this "information and data" has the immediacy, renewability. If you rely on the so-called teacher to explain, that the children would really charnwood question can not be learned in the future handling capability. Focus is on "That's the future," I can not predict get.
The second idea is that you want to "correct" the child could degree in learning, charnwood a "positive initiative" inadequate, especially in the "preparation of materials, tools," on, we need teachers to help them imagine good, even well prepared for the before, it should seriously study. charnwood I think this is very undesirable attitude, but they have. So before this lesson, it is ready to let the kids cans and related tools, is two weeks ahead of time Oh! And patiently reminded. I hope in the next class, can prepare the material three groups.
