Plants need food to live and grow, just like us. But they are like little chefs and make their own food. This food-making process is called photosynthesis. Plants also take up important nutrients from the soil, such as nitrogen, phosphorus, and potassium. These nutrients help them build proteins, grow strong roots, and stay healthy overall. However, some plants, like mushrooms, can't make their own food. They get their nutrition from other sources. To help crops grow well, farmers often add fertilizers to the soil to give back the nutrients that plants have used up.
Important Topics Discussed in Chapter 1
Animals are somewhat different from Plants. To get energy, grow, and repair their bodies, they need to eat plants or other animals. The whole process of how animals take in food, break it down into simpler forms, and then use it is called animal nutrition. Animals that eat grass, like cows, have a unique stomach designed to digest tough plant material. Even tiny living things like an Amoeba have their own way of eating by surrounding their food.

We can measure how hot or cold something is using a thermometer. Think about why you wear different clothes in different seasons. In the summer, light-colored and thin clothes help us stay cool. In winter, we wear thick, often dark-colored clothes to keep our bodies warm. Heat has a natural tendency to move from a hotter object or place to a cooler one. This movement of heat is called heat transfer.
Important Topics Discussed in Chapter 3
Some substances are called acids, and they usually taste sour. A common test for acids is that they turn blue litmus paper red. Then there are bases, which often taste bitter and feel a bit soapy. When acids and bases mix together in the right amounts, they form substances called salts. To tell if something is an acid or a base, we use special substances called indicators, like litmus paper or even turmeric from your kitchen
Important Topics Discussed in Chapter 4
Changes happen all the time, and we can group them into two types. A physical change is one where the substance might look different, but it doesn't become a new substance. For example, when ice melts into water, it's still water – that’s a physical change. On the other hand, a chemical change results in a completely new substance being formed.
Important Topics Discussed in Chapter 5
All living organisms, from the smallest bug to the largest whale, need to respire to live. We need oxygen to unlock the energy stored in the food we eat. Humans and many other animals use lungs to breathe air. Fish have a different system; they use gills to take in oxygen from the water. Plants also "breathe"! They take in and release gases through tiny pores, mostly found on their leaves, called stomata.
Important Topics Discussed in Chapter 6
Living organisms need a proper system to move essential substances like water, nutrients, and gases within their bodies. In this chapter, we'll dive into how both animals and plants move essential substances around their bodies. Animals, like us humans, rely on a circulatory system to ferry blood, oxygen, and even waste. Plants, however, use unique internal "pipes" or special tissues to carry water and food to all their different parts. This whole process of transportation is super important, ensuring every living thing can survive, grow, and work properly.
Important Topics Discussed in Chapter 7
Plants have ways to create new plants, which is called reproduction. They can do this in two main ways: asexually or sexually. Asexual reproduction means a new plant can grow from a part of a single parent plant. This can happen through methods like budding (a small bud grows and separates), fragmentation (a piece breaks off and grows), or through spores (tiny reproductive cells). Sexual reproduction in plants usually involves flowers. Flowers have male and female parts.
Important Topics Discussed in Chapter 8
Motion simply means that an object is changing its position as time passes. Things can move in different ways: in a straight line (like a car on a straight road), in a circle (like a merry-go-round), or along a curved path. Speed tells us how fast something is moving – it’s the distance covered in a certain amount of time.
Important Topics Discussed in Chapter 9
This flow of electricity can cause different things to happen – these are its effects. There are three main effects: the heating effect (like in an electric heater or iron, where electricity makes things hot), the magnetic effect (electricity flowing can create a magnet, which is used in things like electromagnets), and the chemical effect (electricity can cause chemical reactions). In diagrams, we use special symbols to represent different parts of an electrical circuit, like batteries, bulbs, and switches.
Important Topics Discussed in Chapter 10
Mirrors reflect light in such a way that they can form images. Lenses, like those in eyeglasses or magnifying glasses, are different; they bend light as it passes through them. Lenses can also form images, and they are used in many optical instruments.
Important Topics Discussed in Chapter 11
They help influence rainfall patterns, prevent soil from washing away (soil erosion), and generally keep our environment clean and stable. It's crucial that we protect our forests to maintain the delicate balance of nature.
Important Topics Discussed in Chapter 12
Wastewater is any water that has been used and made dirty by homes (from toilets, showers, kitchens), factories, and farms. This dirty water can't just be released back into the environment because it contains pollutants and germs. It needs to be cleaned first. Wastewater treatment plants are facilities designed to clean this water through various stages, removing harmful substances and making it safe enough to be reused or returned to nature. We should all try to use water wisely and avoid polluting it to help reduce the burden on our environment.
