生活中的数学小妙招？

妙招1-多算:中英文基础知识需要多背。数学基础知识呢——计算?这时候你需要举起手中的笔来计算更多。不仅要在学校多做数学,还可以给自己一些在家做不到的数学多练习。

妙招二——多想再写。有的同学遇到一些简单的问题就回想:“这么简单,是不是小菜一碟!”往往这样思考的结果会是错误的。然而,当他们遇到难题时,学生们会站在那里,大汗淋漓。然而,这些行动和想法都是错误的。这种情况下,你要静下心来,慢慢管理条件,然后再写。

妙招三——独立思考。有同学一遇到自己不会的问题就跑去问家长同学。这样做不对。正确的做法是先想想,他们想不出来。问家长老师同学都不晚。上课的时候,往往只是几个同学举手发言。这时候你要学会独立思考,不要一直依赖其他同学的回答,要有自己的定位。

生活中的小知识小实验化学？

1.石墨导电实验

把一根石墨电极或6B的铅笔芯和导线连接在一起，接通电源后，灯泡是否发亮？这个实验说明了什么？

实验说明：①从废旧干电池中拆取石墨电极，市场上6B铅笔芯不常见。②可利用手电筒里的干电池及小灯泡。③可用单面胶带纸把电池、铜丝、小灯泡等固定住。

2、鸡蛋壳与酸的反应

取一个小玻璃杯，放入洗净的碎鸡蛋壳，然后加入一些醋精（主要成分是醋酸），立即用蘸有澄清石灰水的玻璃片盖住。仔细观察有什么现象发生。根据实验现象推测鸡蛋壳里可能含有什么物质。

生活中的数学知识有哪些？

生活中实用的育儿小知识？

育儿小常识

　　1.只要孩子的手脚是温的，一般暂时不会生病。每晚给孩子洗脚或洗澡时，发现孩子的小脚凉了，就可能要生病了，这种情况多数是受凉了，赶紧给孩子煮生姜红糖水：一岁前的孩子，红糖水加一小片生姜煮就可以了，2-4岁的加2片姜，5岁以上加3片姜。喝过后，让孩子赶紧上床睡觉，第二天再喝一次，一般就能及时控制住。

　　2.如果孩子只是小手凉，脚是热的，说明孩子衣服穿少了，要及时给孩子加衣服。

　　3.孩子吃东西老是呕吐或想吐，说明孩子也是受凉了，按上面第一条的方法处理。

　　4.只要孩子不舒服了，首先看舌苔。舌苔发白的就是受凉，在想想这一两天里都给孩子吃什么了，如有寒凉的食物，赶快停掉，再给孩子喝点姜汤水;如果孩子舌苔是 红的，只要给孩子多喝水，或煮萝卜水、梨水给孩子喝，晚上睡觉时再给孩子搓搓脚心，几十下就可以了，孩子的内热很快就会消了。

　　5.晚上睡觉是关键，只要不受凉，再注意饮食上少吃寒凉的食物，孩子一般是不容易生病的。

　　6.如果孩子只是鼻塞，就看他的舌苔，如果舌苔发白，就按风寒感冒的食疗方吃;同时可以给孩子搓搓背部，将背部搓热，孩子的鼻子就通了。

Is the mathematics in the life little subtle move?

Does subtle move 1- calculate: more?  of ≈ of  of Щ of  of J of field of Jiu of  of Ping of damask of  of ≈ of  of apricot ⑽ act bets Chu   to attack at that time you need? the pen in raising a hand will calculate more. Want to make maths more in the school not only, still can give oneself much practice of maths of a few impracticable is in the home.

Subtle move 2 -- want to be written again more. Do some classmates encounter a few simple questions to think back to: ? Stop? of pay mellow horsefly is cole dishful! " the result that often thinks so can be a mistake. However, when they encounter difficult problem, students can stand over, kubla khah dripping wet. However, these actions and idea are wrong. Below this kind of circumstance, you want static next hearts come, run a condition slowly, write again next.

Subtle move 3 -- think independently. The classmate encounters him won't the problem runs to ask the parent the fellow student. Such doing incorrect. Right way is to think first, they want not to come out. Ask the parent Laoshi the classmate is not late. When attending class, often be speech of raise one's hand of a few classmates only. At that time you should learn to think independently, do not depend on the answer of other classmate all the time, want to have oneself fixed position.
