B. Science Fest is taking place at Anu’s School. Look at the materials collected for an experiment related to the changes of substances.
Wax, sugar, spirit lamp, salt, spoon, boiling tube, stand, water, beaker, test tube holder, wire gauze
A) Choose materials from the box to show chemical change and design an experiment.
Answer:
Materials required: Sugar, Spirit lamp, Spoon, Boiling tube, Test tube holder.
Experiment: Place a small amount of sugar in a spoon. Hold the spoon with the test tube holder. Carefully heat the spoon with the sugar using the spirit lamp. As you heat the sugar, observe any changes in colour, odour, or formation of gas.

Observation:

1. The sugar will melt when heated.
2. A brown or black-coloured liquid will form as the sugar decomposes.
3. You might get a caramel-like odour.

B) Write two conclusions of this experiment.
Answer:
This experiment demonstrates a chemical change because:

1. New substances are formed (brown liquid) from the original sugar .
2. The physical properties (colour, odour) of the starting materials differ from the final product.
3. This is a permanent change.
