How would you introduce the concept of evaporation to the foundation phase? Create a simple experiment they can conduct.

Introduction:
Today we are going to learn about a process called evaporation. Evaporation is when a liquid turns into a gas. Have you ever noticed how a puddle of water disappears after a sunny day? That's because the water is evaporating into the air!

Simple Experiment:
Materials needed:
- A small bowl of water
- A marker or tape
- A sunny window or a lamp

Instructions:
1. Place the bowl of water in a sunny window or under a lamp.
2. Use a marker or tape to mark the water level in the bowl.
3. Leave the bowl in the sunny spot for a few hours.
4. Check back on the bowl after some time and observe what happened to the water level.
5. Discuss with the children how the water has disappeared and explain that it has evaporated into the air.

Discussion questions:
- What do you think happened to the water in the bowl?
- Why do you think the water disappeared?
- Can you think of other examples of evaporation in everyday life?

This simple experiment will help children understand the concept of evaporation in a fun and hands-on way.

Introduction:

"Have you ever wondered why wet clothes dry out in the sun? Today, we're going to learn about something called 'evaporation' that makes this happen!"

Experiment:

Materials:

- Shallow dish
- Water
- A piece of cloth (e.g., handkerchief, tissue paper)

Instructions:

1. Fill the dish with a shallow layer of water.
2. Dip the cloth into the water and soak it.
3. Gently squeeze out excess water and place the damp cloth on the edge of the dish.
4. Take the dish outside or place it in a sunny area.

Observations:

Over time, students will observe that the water in the dish decreases and the cloth becomes drier.

Explanation:

"When water is exposed to heat, such as the sun or warm air, some of the water molecules gain energy and turn into a gas called 'water vapor.' This process is called 'evaporation.' The water vapor escapes into the air, making the water level decrease and the cloth dry."

Discussion:

- Discuss that evaporation can also happen from our bodies when we sweat, which helps cool us down.
- Explain that evaporation is important for the water cycle, as water evaporates from oceans and lakes into clouds, forming rain or snow that returns to the ground.
