Teach Your Child Science 1．It is important t。make y。uT child l‘nterested in science from an early age．M0st young children ask a 10t of questions and you should give careful scientific answers．Don’t only giVe facts but try t0 glve explana- tions as well． 2．Science is not iust knowledge；it is a way 0f thinking，a method 0f finding 0ut about the world.We see something．We try to explain it，and we test our idea by seiting up all expefimem．One day you come home and find the plant 0n the table has fallen over．Y0u think it might be the wind from the open windOW 0r the cat．so vou close the window，but lcave the cat in and see what h印pens(you can also try leavlng the window open and shuning the cat out)．Of course，you remember there may be a third explanation． 3．Ask vour child t。geI a piece。f string，some salt，a glass 0f water and an ice cube(冰块)．Tell her to Dut the ice in the water，and then put one end 0f the string on the ice，leaving the 0ther end over the side 0f the dass．Put a lime salt on the ice．wait a minute，and then pull the string；it sh叫ld be attached toeice．Ask the child：“what has happelled”． 4．Probably she won’t kIlO
W．Ask her whether fresh water 0r salt water freezes int0 ice first．If vou live near the sea and have a cold winter，she should know fresh water freezes first as she will have seen that had．pen-Show her how to test the idea by half—filling tWO paper cups with water，adding salt t0 oile．Then put them in the icebox and check every thtee minutes．Write the Yeslllts in a table．The conelusion will be that salt changes the behaViour of water．，r11hinking about the string，we see the salt turned some 0f the ice into water．Then the salt went away into the water and the ice froze again leaving the string attached． 5．Then you can ask，“Will water wittl salt boil at the same kmperature as water witllout salt’’She Call think，tell you her idea and(taking care beeause of the heat)you can test it in the kitchen． 23．Paragrapg 1_______． 24．Paragraph 2_______． 25．Paragraph 3_______． 26．Paragraph 4_______．
