Rekreasi Sains

Koyakkan kertas terpakai yang bersih, campurkan dengan air, tambah beberapa titis pewarna makanan dan kisar dengan bantuan orang dewasa. Campuran menjadi pulpa.

Rekreasi Sains
Langkah 1

Kertas dicampur dan dihancurkan

Koyakkan kertas terpakai yang bersih, campurkan dengan air, tambah beberapa titis pewarna makanan dan kisar dengan bantuan orang dewasa. Campuran menjadi pulpa.

kertas + air + kisar → pulpa
Kertas + air + kisar = 纸加水再打碎
把干净的旧纸撕成小块,加水,请大人用搅拌机打碎。纸和水混在一起变成纸浆(pulpa)。纸浆里有很多细细的纤维。例子:把旧报纸泡水一晚,用手一捏就变成糊状。注意:搅拌机的刀很利,只能由大人操作。
Kertas + air + kisar = paper + water + blend
Tear clean used paper into small pieces, add water, and let an adult blend it. The paper and water become a soft mixture called pulpa, or pulp, full of tiny fibres. Example: Old newspaper soaked overnight turns mushy when you squeeze it. Watch out: The blender blades are very sharp, so only an adult may operate the machine.
Langkah 2

Penurasan menyingkirkan air berlebihan

Tuang pulpa melalui penapis supaya sebahagian besar air keluar sementara serat kertas tertahan. Tekan dengan cermat.

pulpa → tapis → serat tertahan
Penurasan = 过滤
把纸浆倒进滤网,大部分水会流走,纸的纤维被留在网上。再轻轻按压,挤出多余的水。这样纤维才能连成一张纸。例子:用滤网沥煮好的面,水流走,面条留下。注意:按压太大力会把纤维压破洞,要轻轻按。
Penurasan = filtering
Pour the pulp through a screen. Most of the water drains away while the paper fibres stay on top. Press gently to squeeze out extra water so the fibres can join into a sheet. Example: Draining cooked noodles in a colander lets water out but keeps the noodles in. Watch out: Pressing too hard can tear holes in the wet fibre layer, so press softly.
Langkah 3

Ratakan dan keringkan

Bentukkan lapisan nipis di atas dulang, tekan rata dan biarkan kering sepenuhnya. Helaian kering boleh digunakan untuk kad asal sendiri.

ratakan → tekan → keringkan → helaian
Ratakan dan keringkan = 压平并晾干
把纤维在托盘上铺成薄薄一层,压平,然后让它完全干透。干了以后就是一张自己做的再生纸。可以用来做手工卡片。例子:洗好的衣服摊平晾干,比揉成一团干得快。注意:还没干透就撕下来,纸会破,要耐心等。
Ratakan dan keringkan = flatten and dry
Spread the fibres into a thin layer on a tray, press it flat and let it dry completely. The dry sheet is your own recycled paper, ready to become a handmade card. Example: Clothes spread flat on a line dry faster than clothes left in a pile. Watch out: Peeling the sheet before it is fully dry will rip it, so be patient.

Apakah hasil kertas dan air yang dikisar?

Kertas dan air dikisar = 纸和水打碎
题目问:纸加水打碎后,得到的是什么。线索是“kertas”“air”和“dikisar”。回想第1步打碎后的糊状东西叫什么。水蒸气和铁粉都不是纸变成的,可以用来排除。例子:香蕉加牛奶打碎,会变成浓浓的奶昔。注意:打碎后的东西是湿软的,不是一张纸。
Kertas dan air dikisar = paper and water blended
The question asks what we get after blending paper with water. The clues are 'kertas', 'air' and 'dikisar'. Recall the soft mushy mixture from Step 1. Water vapour and iron filings do not come from paper, so you can rule them out. Example: Blending banana with milk gives a thick smoothie. Watch out: The blended result is wet and soft, not a finished sheet of paper.

Apakah fungsi penapis?

Fungsi penapis = 滤网的作用
题目问滤网有什么用。回想第2步:纸浆倒进滤网后,水和纤维各去了哪里。想想滤网会不会把纤维溶掉,或马上把纸浆弄干。例子:泡茶用的茶隔,让茶水流下,茶叶留在里面。注意:滤网不是把所有东西都挡住,有东西会流走。
Fungsi penapis = the job of the filter
The question asks what the filter does. Recall Step 2: when pulp was poured onto the screen, where did the water go and where did the fibres go? Ask whether a screen could dissolve the fibres or dry the pulp at once. Example: A tea strainer lets tea pass through but keeps the leaves inside. Watch out: A filter does not block everything; something passes through it.
