Science Standard 8

Understanding Science series (Revised Edition) is a product of thorough research and analysis of the existing course books in the market. It takes cognisance of the fact that science is best learnt through doing rather than listening. As such, it is a tremendous improvement of both the previous version of itself and any other course book in the market. It emphasises challenges faced by modern-day learner and presents concepts in the most simple and easy-to-understand manner. It is developed in line with the revised curriculum of 2003 and incorporates all emerging issues in Science! 

The following features make the series a unique one and therefore the course book series of choice for teaching Science: 
• Concepts are organised in clear chapters written in simple language with short and easy-to-understand notes. 
• Contain appropriate and full colour illustrations making them very attractive and pupil-friendly. 
• Has Practice Exercises at the end of each subtopic, Revision Exercises at the end of each topic and a Chapter Summary of the main concepts learnt at the end of each unit for quick revision.
