Teach Your Child Science

1 It is important to make your child interestedin science from an early age. Most young children ask a lot of questions andyou should give careful scientific answers. Don't only give facts，but try to give explanations as well.

2 Science is not just knowledge；it is a way of thinking，a method of findingout about the world. We see something. We try to explain it，and we test our idea by setting up an experiment. One day you comehome and find the plant on the table has fallen over. You think it might be thewind from the open window or the cat，so you close thewindow，but leave the cat in and see what happens （you can also try leaving the window open and shutting the cat out）.Of course，you remember there may be a thirdexplanation.

3 Ask your child to get a piece of string，some salt，a glass of water and an ice cube （冰块）.Tell her to put the ice in the water，and thenput one end of the string on the ice，leaving the otherend over the side of the glass. Put a little salt on the ice. Wait a minute，and then pull the string； it should beattached to the ice. Ask the child：“What has happened？”

4 Probably she won't know. Ask her whetherfresh water or salt water freezes into ice first. If you live near the sea andhave a cold winter，she should know fresh water freezesfirst as she will have seen that happen Show her how to test the idea byhalf-filling two paper cups with water，adding salt toone. Then put them in the icebox and check every three minutes. Write theresults in a table. The conclusion will be that salt changes the behaviour ofwater. Thinking about the string，we see the salt turnedsome of the ice into water. Then the salt went away into the water and the icefroze again leaving the string attached.

5 Then you can ask，“Willwater with salt boil at the same temperature as water without salt？”She can think，tell you her idea and （taking care because of the heat）you can testit in the kitchen.
