適用年齡：5-6歲
活動(dòng)目標(biāo)：
1、引導(dǎo)幼兒觀察了解溶解現(xiàn)象，明白條件不同，現(xiàn)象也不同。
2、培養(yǎng)幼兒的觀察力及探究興趣，體驗(yàn)成功的快樂與喜悅。
3、滲透sugar, water, chopsticks, dissolve, cup，drink-maker, waiter,

活動(dòng)過程：
1、第一次調(diào)制飲料
（1）你們喜歡喝飲料嗎？這有許多材料，你們可以選擇自己喜
歡的進(jìn)行調(diào)制。
Boys and girls, do you like drinking?

你調(diào)的是什么飲料？飲料粉去哪了？

2、討論：在調(diào)制飲料的時(shí)候，飲料粉/糖去哪了？（溶解了）

How can it dissolve fully? (I can put more water; I can mix them with chopsticks: I can……)
3、體驗(yàn)條件不同，現(xiàn)象也不同。
（1）驗(yàn)熱水溶解快，涼水溶解慢。
  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）通過操作觀察到冰糖（塊狀）溶解的慢，糖（粉末狀）溶解的快。
