Have you seen tiny droplets of water on the leaves? It looks beautiful, doesn’t it? Kids like splashing dews from the leaves and enjoy their morning time. Besides this, they must have seen water droplets on a glass of water or a glass window. But, they might not be aware of how these dews are formed. How does dew form? To teach them about this concept, you can conduct science experiments for kids. These experiments will help them learn about the reason behind its occurrence.

Dew is the water droplet that forms on the surface of leaves or any objects that when the water vapor condenses into a liquid at low temperature. The water vapor is condensed into a droplet when the temperature drops. The droplets on the leaves or grass look like a pearl. Sometimes, children might get confused with rainwater. But, it is important for children to know that the dew is formed due to the condensation of water vapor. And, it is not rainwater that is accumulated on the surface of the object.
What is a Dew?
Dew is a water droplet that is formed due to the condensation of water vapor. Most of the time, you must have seen dew on leaves, grass or any other objects when there is an increase in the humidity. You can even witness this on the glass window on a summer morning. The dew is formed when warm air comes in contact with a cool surface. Dew helps plants in reducing water stress. Plants can retain moisture and become resilient even during dry conditions. They can survive drought conditions very easily. It reduces the temperature of the plant during the summer season. Besides this, dew also helps in the germination of seeds. It gives moisture to the soil for the seeds to grow into a sapling and then into a mature plant.
Fun Facts about How Does Dew Form?
- Dew is formed in the night when the temperature drops.
- The water vapor condenses into a droplet on the object.
- The temperature at which the condensation occurs is called the dew point.
- If the temperature reaches below the dew point, it becomes frost.
- The dew point is higher in humid regions compared to the dry regions.
- Dew helps plants to retain moisture even during drought or dry conditions.
- Cool air cannot hold water vapor as compared to warm air.
- Dew is observed in leaves, grass, a glass of water, glass window, etc.
- Dew helps in reducing the transpiration process in the leaves.
- Dew helps in increasing the humidity and absorption of water.
- Dew keeps plants cool and hydrated during hot conditions.
- Cactus can survive with the moisture obtained from the dew.
- It helps in retaining the moisture in the plants.
Easy Science Project: How Does Dew Form?
To teach the kids about the concept of dew and how it is formed, you can make them do experiments at home. Dew undergoes a condensation process which is basically a change of water vapor into a liquid. How does dew form? It forms when the temperature drops. The place where humidity is high such as coastal regions, tend to observe more dew than other areas. Dew is mostly like to form during the night time when the temperature drops. To explain this, check out the simple experiment for kids given below.
Aim of the Project
To perform and observe the experiment on how a dew is formed using the material available at home. This experiment will give a clear understanding of the concept and factors that are responsible for forming dew on the objects.
- Two glasses
- A cup of ice
- A cup of water
- Post stick
- A marker
- Take a glass and fill it with water kept under room temperature.
- Label it as A on the post stick and paste it on the glass.
- Take another glass and label it as B using the post stick.
- Add a cup of ice into the glass and fill it with water kept under room temperature.
- Keep the two glasses aside for 15 to 20 minutes.
- Finally, observe and record the changes.
It is observed that glass B showed droplets of water on the surface of the glass compared to glass A. It means that dew is formed when the water vapor changes into droplets of water when the temperature drops. The process of changing the gaseous state to a liquid is called condensation. The water droplets that see outside the glass is the condensation process. This is a simple experiment to teach kids about the formation of dew on the surface of objects.
Benefits of Learning about Dew
Some of the benefits of learning about dew are mentioned below:
- Develops understanding of the condensation process in children.
- Enables children to gain knowledge on objects that form dew on their surfaces.
- Imparts scientific knowledge on dew to children.
- Helps in understanding the importance of dew in the ecosystem and the environment.
- Enhances the learning experience of children.
- Helps in learning about the importance of the condensation process in the water cycle.
- Creates interest to explore and experiment about dew in order to acquire knowledge.
- Improves the academic performance of children when asked about dew in the exams.
- Motivates children to perform experiments on dew once they understand the concept.
- Enables children to explore objects that form dew so that they can learn practically and understand them better.
Frequently Asked Questions on How Does Dew Form?
How does dew form?
Dew is formed when the water vapor changes into a liquid after the temperature drops. The temperature at which the dew is formed is known as the dew point.
What are the benefits of learning about dew?
The benefits of learning about dew are that it helps children learn about the condensation process. They can learn and understand the importance of dew in the ecosystem.
