Answer: (a) The beaker is suspended from a spring balance. If an object is added to the beaker, the net weight held by the spring balance increases. Thus, the reading of the spring balance will increase by the weight of the cork.

(b) The beaker is suspended from a spring balance. If an object is added to the beaker, the net weight held by the spring balance increases. Thus, the reading of the spring balance will increase by the weight of the heavy metal.

Theme : There are different types of changes in our surroundings which are slow/tast, reversible/irreversible, periodic/non-periodic and physical/chemical. In a physical change, no new substance is formed while in a chemical change, a new substance with properties different from the elements forming that substance is formed. Learning of these changes helps in developing different scientific skills. LEARNING OUTCOMES The children will be able to : illustrate different changes occurring in nature with examples learned in previous classes. perform some activities to show some well-known changes. differentiate between physical and chemical changes and classify the changes. INTRODUCTION Change is a universal phenomenon. Almost all substances undergo change. While some changes are easy to detect, some are so small that they are difficult to identify. These changes have been taking place around us continuously, such as day and night, change of seasons, growth of plants and animals, ripening of fruits, burning of fuel, melting of ice, cooking of food, etc. The change can be, natural and manmade, slow and fast, periodic and non-periodic, desirable and undesirable, small and large, reversible and irreversible, temporary and permanent, etc. All these changes are exciting and each one of them has a reason behind it. Since most of the changes are different in nature, it is necessary to study them in detail. SLOW AND FAST CHANGES The changes that take longer time to complete are called slow changes. They take hours, days, months or even years to occur. Examples : Rusting of iron, change of seasons, formation of curd from milk, a child growing into an adult, formation of fossil fuels from dead plants and animals, etc. Physical and Chemical Changes
