タイトルにある"kagome"は英語オリジナルなワードには思えません。
でも小文字から始まっているので、ケチャップのカゴメさんでもなさそう。
さては「籠目」かな？と読み進めてみると、２パラ目にその説明がありました。
Exotic materials known as kagome superconductors can play host to a rare state of matter in which electric currents form “loops” around unit cells in the material’s crystalline lattice. This discovery, made by researchers at Switzerland’s Paul Scherrer Institute (PSI) together with international collaborators, could reveal new information about how superconductivity emerges in materials where complex effects such as frustrated magnetism and intertwined orders play a major role.
Kagome metals are named after a traditional Japanese basket-weaving technique that produces a lattice of interlaced, corner-sharing symmetrical triangles. ★When the atoms of a metal or other conductor are arranged in this so-called kagome pattern, their electrons behave in unusual ways, giving rise to interaction-driven electronic phases of matter that can be identified by studying symmetries of the material.★
a lattice（格子）は、下図では六角形パターンのことですね。
引用部分★最後の文章★を分解してみましょう。
主語は１つですが、内容は因果関係を含めて盛りだくさん！
①When the atoms of a metal or other conductor are arranged in this so-called kagome pattern, ②their electrons(主語) behave in unusual ways, ③giving rise to interaction-driven electronic phases of matter ④that can be identified by studying symmetries of the material.
①ある金属または他の導体の原子がこのいわゆる籠目パターンに配列されると、
②その電子の振る舞いが異常になる。
③このため、相互作用による電子相が生じる。
④この電子相は、この物質の対称性を研究することで特定し得る。

How many layers do you have in your cup?
（音量maxにすると、うっすらと英語の説明が入っています）
Water and oil are not mixed, but make layers.
Let’s pour oil and water.
Which is on the other? Which is under the other?

Properties of metals

propertyは物の特質や特性を意味する単語です。可算名詞です。
金属のpropertiesを読んでみましょう。
A property is a word used to describe a material or object and tells us something about it.
- Metals are usually shiny. The shine that we see when light reflects off the surface of a metal is called the lustre of the metal.
- Most metals are hard and they feel heavy.
- We say metals are dense as their particles are packed close together.
- Metals conduct electricity and heat well. (You will learn more about electricity next term. In Grade 6, you will learn about metals as conductors of electricity.)
- Metals are malleable (they can be shaped into flat sheets) and they are ductile (this means they can be made into thin wire)
- Most metals can be heated to high temperatures without melting or changing their shape, which is one of the reasons why pots and pans are made of metal. Can you think of any other reasons why pots and pans are made of metal?

受粉についての英文です。
正確に読めますか？書けますか？
The flowers produce pollen. Insects carry the pollen from one flower to the next. This is called pollination.
- The pollen fertilises the ovules in the flower.
- The fertilised ovules now develop into seeds.
- The seeds are then dispersed and start to grow in a new place.
- Seeds can be dispersed in different ways.
Look at the pictures showing ways in which seeds are dispersed.
Discuss these four ways and explain how you think the seeds are adapted in each method to be the most efficient.
