an experiment
|
|
today,i conduct an experiment about destroying a material. in the first,the teacher told us the theory about the experiment.and then,we must do it with myself.we press a very big force to the material.them we observed the phenomenon.with the time go,the stick that made by iron became thinner and thinner,and broke to two sides at last.we wrote down the data,and calculated the result.then ,the experiment was over. i am sorry to tell something boring to you,but i want to improve my English level by writing more. thank you. |
