What is he known for? Leonardo was fascinated by flight and designed many flying machines, including a flying suit and a helicopter-like device. Although he didn't build a working flying machine, his designs laid the groundwork for modern aviation. Leonardo created a famous drawing called “The Vitruvian Man” which depicts a man in two superimposed positions with his arms and legs apart inside both a square and a circle. It represents the connection between the human body and geometry. Botanical studies Leonardo had a keen interest in nature and studied various plants and animals in detail. His detailed botanical drawings were ahead of their time and still admired by scientists and artists today. The Last Supper Another famous painting by Leonardo is “The Last Supper”. It depicts the moment when…

The composition of paper Paper is made from wood pulp, which is obtained by breaking down trees into fibres. The fibres are then mixed with water and other additives, such as chemicals, to create a pulp. This pulp is spread onto a screen and pressed to remove excess water, resulting in a thin sheet of paper. The main component of paper is cellulose, which gives it strength and flexibility. The process of paper recycling Collection: The first step in paper recycling is collecting used paper. This can be done through recycling bins at schools, offices and recycling centres. It’s important to separate different types of paper, such as newspaper, cardboard and office paper, to ensure efficient recycling. Eco-warriors recycle for a brighter future! Remember, reduce, reuse and recycle paper to create…

Here are some examples: Glass packaging: Recycled glass is commonly used to produce new glass bottles and jars. By using recycled glass, we reduce the demand for new raw materials, conserve energy and lower carbon emissions. Fibreglass: Recycled glass can be converted into fine fibres and used as a reinforcing material in fibreglass products. It is widely used in insulation, roofing materials and even in the production of sports equipment like surfboards. Construction and infrastructure: Crushed recycled glass, known as glass aggregate, can be used as a substitute for traditional construction materials such as gravel and sand. It is utilised in road construction, concrete and landscaping applications, providing an eco-friendly alternative. Decorative and artistic applications: Recycled glass is valued for its unique and attractive appearance. It is often used in…

By choosing recycled paper products, we contribute to reducing waste and supporting sustainable practices. Paper crafts and art: Recycled paper can be used for creating various crafts, such as origami, greeting cards and papier-mâché sculptures. Artists and craft enthusiasts can unleash their creativity while promoting environmental awareness. Insulation and…

Here are a few examples: Packaging industry: Recycled plastics are commonly used in the production of food containers, bottles and packaging materials. By using recycled plastics, we reduce the need for new plastics production and help conserve resources. Textile Industry: The fashion industry has embraced recycled plastics, using it to create fabrics for clothing and accessories. These fabrics are often known as “eco-friendly” or “sustainable” textiles, as they reduce the reliance on petroleum-based materials. Construction Industry: Recycled plastics can be transformed into materials used in construction, such as plastic lumber, insulation and even bricks. These materials are durable, lightweight and resistant to rot, making them an excellent alternative to traditional building materials. Automotive Industry: Recycled plastics is also finding its way into the automotive industry. It is used to manufacture car…

But, did you know that these adorable creatures are facing a huge problem? It’s called litter, and it’s something that we humans leave behind in the parks, like plastic bags, candy wrappers and bottles. When we don't clean up after ourselves, it can really harm these small animals and the places they call home. Mice, for example, might get tangled up in pieces of trash, making it hard for them to move around and find food. Snails could mistake small bits of plastic for their favourite snacks, but eating litter can make them very sick. And for cute rabbits, lizards and frogs, litter can be like a dangerous obstacle course that they have to navigate every day. But wait, here’s the good news! We can all be superheroes for these…

PAPER – A tale of ancient wisdom (Around 105 AD) Imagine a world without paper! Long, long ago, people wrote on stones and animal skins. But then, a fantastic discovery changed everything: paper! The ancient Chinese created paper from mulberry trees, helping knowledge and stories to spread far and wide. In the 15th century, the printing press was invented, leading to a significant increase in the demand for paper and the spread of knowledge and literacy. Paper is light, easy to write on and it made books accessible to many. Today, we still use paper for books, drawings and important documents. But remember, using too much paper can lead to cutting down too many trees, which harms our environment. GLASS – The magic of transparency (Around 3500 BC) Have you ever peered…
