Activity Name: Burning of Camphor in Changes around Us
In this experiment, we will observe the burning of camphor and note the changes that occur during the process. Camphor is a substance commonly used in rituals like “harathi” and has various other applications, including insect repellent and medicinal use.
- Dish or container
- Lighter or matchstick
Step by Step Procedure:
- Take a small quantity of camphor and place it in a dish or container.
- Ensure you are in an open-air environment or a well-ventilated area.
- Use a lighter or matchstick to ignite the camphor and observe the process of burning.
- Initially, camphor changes from a solid state to a liquid state before it starts burning.
- The camphor will produce a flame and continue burning until it is fully consumed.
- During the burning process, the quantity of camphor reduces as it turns into gaseous products and dissipates into the air.
- You may notice a distinct smell as camphor burns, which is one of its characteristic properties.
- After the burning process, the original camphor is no longer present in its initial form.
- Perform the experiment in a safe and well-ventilated area to avoid inhalation of fumes.
- Handle the camphor and the flame with caution to prevent accidents or burns.
- Keep the experiment away from flammable materials and ensure proper fire safety measures are in place.
Lesson Learnt from Experiment:
Through this experiment, we observe that the burning of camphor is a chemical change. During this process, camphor undergoes a transformation, changing its state from a solid to a liquid and finally to gaseous products. Additionally, a new substance, such as carbon dioxide and water vapor, is formed during the combustion of camphor.
