Science Activity: Self-making drinking（大班科学活动：自制饮料）

适用年龄：5-6岁
活动目标：
1、引导幼儿观察了解溶解现象，明白条件不同，现象也不同。
2、培养幼儿的观察力及探究兴趣，体验成功的快乐与喜悦。
3、渗透sugar, water, chopsticks, dissolve, cup，drink-maker, waiter,
shopper等词汇，句型"I like drinking……"; "I can……"; "I want to be……"等。
活动准备：
1、环境准备：在区角内开设"饮料店"的活动。
2、材料准备：一次性杯子若干，糖、冰糖、各种饮料粉、筷
子、调羹等。
活动过程：
1、第一次调制饮料
（1）你们喜欢喝饮料吗？这有许多材料，你们可以选择自己喜
欢的进行调制。
Boys and girls, do you like drinking?
What drink do you like? (I like drinking……)
Look, there are many things. Now, choose and make it.
（2）幼儿动手操作，教师给予指导和鼓励。
你调的是什么饮料？饮料粉去哪了？
What drink do you make?
Where is the drink-powder? (It dissolves in water)
2、讨论：在调制饮料的时候，饮料粉/糖去哪了？（溶解了）
我发现有的小朋友喝完饮料后，杯底还有饮料粉，为什么？（没有充分溶解）怎样才能让它充分溶解呢？（我用 ……）
Boys and girls.
When you make the drink, where is the drink-powder/sugar? (It
dissolve in water)
I find there is still some drink-powder in the cup after drinking out, why? (Some doesn't dissolve)
How can it dissolve fully? (I can put more water; I can mix them with chopsticks: I can……)
3、体验条件不同，现象也不同。
（1）验热水溶解快，凉水溶解慢。
  These are two cups of water, put the same drink-powder and mix them, what do you find? (One dissolves quickly, and the other one slowly)
  Why? Touch the cups. (One is hot and dissolves quickly, the other one is cool and dissolves slowly)
  （2）通过操作观察到冰糖（块状）溶解的慢，糖（粉末状）溶解的快。
  Boys and girls.
   Put ice-sugar into a cup and put sugar into another one, mix them.
 

  What will happen? (The ice-sugar dissolves slowly and the sugar quickly)
4、第二次调制饮料
我们再调一次，这次要让饮料粉充分溶解。
We try it again. This time , we have the drink-power dissolve fully.
5、游戏：饮料店
（1）小朋友调出这么多的饮料，我们来开一个饮料店吧！谁
想做调制师/服务员/顾客？
