Boys and girls, let’s do an experiment (实验) in today’s lesson.

What we need:

How we do the experiment:

1.Pour tag water into the glass until it is about 2/3 full.

2.Drop the egg carefully into the glass and watch it going down towards the bottom.

3.Add about five spoons of salt to the water. Test to see if the egg goes up.

4.Add more salt if the egg is still at the bottom.

The science behind it:

Things go down in the water when they are denser (密度更大的) than the water. By adding salt, we make the water denser. Once the water is denser than the egg, it goes up and floats (漂浮) on the water.

You can also try other things to see if you can have the same result.

文章大意:本文主要介绍了中国的小学和初中开始开设劳动课程,让学生意识到劳动教育的重要性。

【推荐3】①Since last September, primary and junior high schools have offered labor courses. That has made students realize the great importance of labor education, encouraging students to do activities such as cooking, decorating houses and volunteer work. Some students in China were given specialized homework during the winter vacation.

②Xue Youmei, a Grade 7 student, spent the winter holiday in Guangxi doing her specialized homework. Everything about village life was novel to Xue who was used to city life. She joined her family to work in a farm field planted with Chinese water chestnuts (荸荠). Xue, wearing a pair of gloves, helped her father pick up water chestnuts in the field.

③For Yang Liqiao, a Grade 6 student, the past winter holiday gave her a new identity (身份) — rubbish sorting guide. Yang wore a volunteer’s T-shirt and recorded the situation of the rubbish sorting work at her community. Yang also invited her classmates to walk around the park nearby to pick up rubbish on the ground. Yang’s father found labor activities offered students a chance to get knowledge, which was not caught at class.

④Here are two more examples about the specialized homework. To let students enjoy play-based learning, some students were asked to work with parents to decorate their homes with New Year paintings. The purpose of the task was to develop students’ new thinking and creation. And some were required to collect physics-related Chinese poems, make an analysis (分析) and draw a conclusion.
