One thing to be kept in mind all along the way for Science preparation is that practice is the key here. The more you practice for every topic, the better understanding is achieved.
These topics should be practiced as much as possible. The key to solve problems is to by-heart the formulas, understand the theorems, and practice as many times as possible. Science can become your favorite subject with practice and dedication.

2. Practice, above all. The range of questions in class 7 is limited. With substantial practice, most question types will be internalized, and you won’t have to think for most questions.
3. Develop a good understanding of topics. It will help you with those challenging questions or derive formulae in the rare chance you forget. This can be done by watching videos for various topics that will help you develop an interest in the topic.
4. Understand all the concepts in as much depth as you can. And then solve different varieties of questions and problems. Attempt various topic-wise and chapter-wise tests. Also, practice mre with sample papers and previous year papers. Use your knowledge to solve some real life questions as well.
5. Give more importance to the topics which have high weightage. Solve the previous year exam papers which will increase your confidence and give you a pre-exam feel. It also helps to brush up all your concepts before the exam.
6. Don’t just read or mug up the topics but practice them. This is the most important thing which you need to keep in mind as reading Science does not help you. Instead, make a routine and give some time for practice.
Chapter 1: Nutrition in Plants
This chapter covers the process of food preparation by plants by utilising raw material present in the environment.
Chapter 2: Nutrition in Animals
This chapter is about nutritional habits of animals. You will get to know about different organs that are involved in the process of obtaining nutrition from food that you eat. It also covers about nutrition in amoeba.
Chapter 3: Fibre to Fibre
This chapter involves a study of wool and silk which are natural fibres. It also covers the steps involved in the processing of wool and silk fibre.
Chapter 4: Heat
In our day-to-day life, we come across a number of objects. Some of them are hot and some of them are cold. This chapter tries to find out how hot or cold an object is.
Chapter 5: Acids, Bases and Salts
In our daily life, we use a large number of substances which are acid, base or salt. They vary in taste and touch. They also lead to changing colours of specific substances which are called indicators. Acid and base combine and form salt which may be acidic, basic or neutral in nature. This is called neutralisation which hasimportance in our daily life. This chapter covers all these things in detail.
Chapter 6: Physical and Chemical Changes
Every day you come across many changes in your surroundings. These changes may be physical or chemical. This chapter helps you to classify changes occurring around you as physical or chemical or both in one process.
Chapter 7: Weather, Climate, and Adaptations of Animals to Climate
In this chapter, students can learn about phenomenon like why do we have different climates on different parts of the earth and how and why seasons change after a particular time. Why sometimes it is bright and sunny in the morning and then suddenly it starts to rain. You will get answers to all such questions in this chapter.
Chapter 8: Wind, Storms and Cyclones
This chapters covers many natural phenomena related to wind and the pressure difference on earth surface. You may see such phenomena like storms and cyclones on TV and in newspapers occurring frequently on the earth in various regions.
Chapter 9 – Soil
Chapter 10 – Respiration in Organisms
Chapter 11 – Transportation in Animals and Plants
Chapter 12 – Reproduction in Plants
Chapter 13: Motion and Time
Once you change your position from one place to another place, you are said to be in motion. Sometimes you cover the same distance in a short time while some times it takes a long time. We say slow and fast in these cases. Distance and time are inter-related in the form of speed.
Chapter 14 – Electric Current and its Effects
Chapter 15 – Light
Light travels in a straight line and is composed of seven colors. Rainbows is a natural phenomenon which supports this. Light also reflects back when is incident on a smooth surface. Mirrors are based on the same concept. Image is formed in the plane mirror due to reflection of light. The image formed is virtual, erect and laterally inverted.You see so many other types of optical objects also around you, like spoon, rear view mirrors in vehicle, magnifying glasses, mirrors at blind turns, shaving mirrors etc. Some of them form real image and some also forms virtual images. The mirror which is bulged out is convex mirror. It forms erect, virtual image which is smaller in size. It is also used as magnifying glass. The mirror which is bulged in is concave mirror. It can form both real and virtual image.
Chapter 16 – Water: A Precious Resource
Understand and learn about different sources of freshwater. Understand how water on the earth is managed by various processes that result in the water cycle. Understand and learn the concept of groundwater and the various terms related to it.
Chapter 17 – Forests: Our Lifeline
Observe what happens when a plant is uprooted. Understand the importance of trees and forests in our daily lives.
Chapter 18 – Wastewater Story
Understand what is sewage, how it is produced and what happens when sewage remains untreated. Learn about the various techniques that can be applied in daily life to reduce wastewater. Understand the sewage treatment process in detail.
