In their Science classes, Year 5 have been learning the unit: Materials and the students have been investigating solids, liquids and gases. The students took part in different experiments when they were offline and they have also taken part in experiments online such as slow evaporation and testing solubility.

在科學課上，五年級學生一直在學習單元：材料，學生們一直在研究固體、液體和氣體。這些學生在線下課時參加了不同的實驗，他們也參加了在線實驗，如揮發和測試溶解度。

In order to help them remember the technical Science vocabulary from this unit, the students created videos of them showing how to do the Science experiments. By teaching others it helps them to have a deeper understanding of what they"re learning and it can help them to remember what they"ve learnt. It also encourages them to practice their English speaking skills and presenting skills too whilst we are offline. As you can see from the video, the students have done an amazing job and they"re all presenting in their second - or even their third language!

為了幫助他們記住本單元的技術科學詞匯，學生們制作了展示如何進行科學實驗的視頻。通過教別人，他們可以更深入地了解他們正在學習的內容，并記住所學的內容。這也鼓勵他們在線下練習英語口語和演講技巧。正如你從視頻中看到的，學生們做得非常出色，他們都在用第二種甚至第三種語言演講！

Other students can benefit from their videos by watching and learning how they can do fun Science activities at home with their siblings or parents using minimal equipment. Whilst we are offline, the students are unable to take part in some of the practical activities that they might usually do at school, but this is a way for them to take part in practical activities where they can learn lots and be away from screens. You can do all of the experiments by using things that you have around the house - but students should please make sure they ask for parental permission and help to clean up any mess afterwards.

其他學生可以通過觀看和學習如何在家中與兄弟姐妹或父母一起使用最少的設備進行有趣的科學活動，從而從他們的視頻中受益。當我們進行線上課時，學生無法參加他們通常在學校進行的一些實踐活動。這個活動他們參加實踐的一種方式，他們可以在實踐活動中學到很多東西，遠離屏幕。你可以用家里的東西做實驗，但學生們應該確保他們得到家長的允許，并在之后幫助清理亂糟糟的東西。

Thank you to the supportive parents and siblings of the students in Year 5 for helping them organise the materials and film their Science experiments.

Amazing work, Year 5! You should continue to be proud of yourselves for your hard work online and your brilliant presenting skills and explanations! Keep it up!

感謝支持五年級學生的父母和兄弟姐妹們，幫助他們整理材料并拍攝他們的科學實驗。

五年級的作品太棒了！你們應該繼續為自己在網課的努力以及你出色的演講技巧感到驕傲！堅持下去！

This activity links to the following Cambridge learning objectives.

該活動與以下劍橋學習目標相聯系。

5Cp.02Know the main properties of water (limited to boiling point, melting point, expands when it solidifies, and its ability to dissolve a range of substances) and know that water acts differently from many other substances.

了解水的主要性質（限于沸點、熔點、凝固時膨脹以及溶解一系列物質的能力），并了解水的作用與許多其他物質不同。

5Cp.01Know that the ability of a solid to dissolve and the ability of a liquid to act as a solvent are properties of the solid and liquid.
