双语科学小制作：熔岩灯制作

Today, we are going to wrap up our science project with a fun and interactive bilingual activity. 今天，我们将用一个有趣而互动的双语活动来结束我们的科学项目。

For this activity, we are going to make a lava lamp using simple household items. 这个活动中，我们将使用简单的家居用品制作一个熔岩灯。

Here's what you'll need: 以下是你所需要的材料：

• A clear plastic bottle 一个透明的塑料瓶
• Water 水
• Vegetable oil 植物油
• Food coloring 食用色素
• Alka-Seltzer tablets 阿司匹林泡腾片

First, fill the plastic bottle about three-fourths full with vegetable oil. 首先，用植物油将塑料瓶装满四分之三左右。

Next, fill the rest of the bottle with water, leaving a little bit of space at the top. 然后，用水将瓶子装满，留一点空间在顶部。

Now, add a few drops of food coloring to the bottle. You can choose any color you like! 现在，向瓶子里滴入几滴食用色素。你可以选择任何你喜欢的颜色！

Finally, break an Alka-Seltzer tablet into a few pieces and drop them into the bottle. 最后，将一片阿司匹林泡腾片打碎成几块，放入瓶子里。

Watch as the mixture starts to bubble and fizz, creating a mesmerizing lava lamp effect! 观察混合物开始冒泡和发泡，产生迷人的熔岩灯效果！

This activity not only introduces children to the concept of density and chemical reactions, but also provides an opportunity for them to practice their bilingual skills. 这个活动不仅向孩子们介绍了密度和化学反应的概念，还为他们提供了练习双语能力的机会。

Now, let's take turns describing what we see happening in both English and our second language. 现在，让我们轮流用英语和我们的第二语言描述我们所看到的情况。

Great job, everyone! I hope you had fun exploring science in a bilingual way. Well done on completing our science project! 太棒了，大家！我希望你们通过双语方式探索科学的过程中玩得开心。完成我们的科学项目真是太棒了！
