Clouds in Kitchen in Rain – Class 6 Science Experiment

Chapter Name: Rain

Activity Name: Clouds in Kitchen in Rain

Activity Description:

In this experiment, we will observe the formation of clouds and explore the similarities between the evaporation of water from water bodies and from a heated bowl in the kitchen.

We will also discuss the changes that occur in the sky and atmosphere before it rains, as well as the changes in clouds before rainfall.

Required Items:

• Vessel filled with water
• Stove
• Plate
• Cool water

Step by Step Procedure:

1. Take a vessel filled with water and place it on a stove.
2. Heat the vessel slowly and observe it for some time.
3. After a couple of minutes, cover the vessel with a plate.
4. Wait for a few minutes and then remove the plate. Observe the inner surface of the plate for any changes.
5. Pour some cool water on the plate and observe what happens.
6. Compare the evaporation of water from the surface of water bodies and the evaporation of water from the heated bowl in the kitchen.
7. Take note of any similarities between the two cases.

Experiment Observations:

1. Upon heating the vessel, water starts to evaporate and forms steam.
2. When the plate is placed on top of the vessel, water vapor condenses on the inner surface of the plate, forming tiny droplets.
3. The droplets on the plate resemble clouds.
4. Pouring cool water on the plate causes the droplets to merge and form larger droplets, similar to the process of cloud formation.

Precautions:

• Handle the hot vessel and plate with caution to avoid burns.
• Ensure a safe distance between the flame and the vessel to prevent accidents.
• Use appropriate protective equipment, if necessary, when handling hot objects.

Lesson Learnt from Experiment:

1. The experiment demonstrates the process of evaporation, condensation, and cloud formation.
2. It highlights the similarities between the evaporation of water from water bodies and the evaporation of water from a heated bowl.
3. Water vapor plays a crucial role in the formation of clouds.
4. Clouds are formed when moist air rises and cools, causing the water vapor to condense into visible droplets or ice crystals.
5. Clouds are carried by winds from the sea to the land, and the colder upper layers of the atmosphere cool the clouds, leading to the possibility of rain.
6. Not all clouds cause rain, and specific changes occur within the clouds before rainfall.
7. The experiment encourages observation skills and understanding of the natural processes involved in weather phenomena like rain.
