  Scientific Explanation: Glass is a smooth surface, so light reflects off it easily. When light hits the glass, some of it goes through, and some of it bounces back. This is called reflection. We can see our reflection because the light that bounces back carries the image to our eyes. Child-Friendly Explanation: Light hits the glass and jumps back — like a ball bouncing on the ground! That’s why we can see ourselves in windows sometimes. The glass works like a mirror when light shines on it. The glass is shiny, so the light likes to bounce on it. That’s why windows look bright and sometimes show our face when the sun is shining. It’s like the glass is saying, “Hello! I can show your reflection!". Open-ended Questions: -Do you think the light can bounce somewhere else? Where? -What happens if we move the flashlight closer or farther? -Do you see the same thing if you turn off the light? Why? Short Hands-on Activity: “Reflection Hunt!” Give children a small flashlight. Let them shi...

Scientific Explanation: Frost forms when the temperature outside drops below freezing. At night, water vapor in the air touches cold surfaces, like metal or glass, and turns into tiny ice crystals. This process is called freezing or frost formation. Cars cool down faster because metal loses heat quickly, so water freezes more easily on them. Child-Friendly Explanation: Sometimes the night gets really cold, and the tiny water drops in the air turn into ice. That’s why the car looks like it has a shiny, icy blanket in the morning! It’s just water that froze because the car got very cold. Open-Ended Questions: -What would happen if the weather stayed warm all night? -Do all surfaces freeze the same way? Why or why not? Hands-On Activity: “Make Your Own Frost”  Place a metal spoon or small metal cup in the freezer for 10–15 minutes. Take it out and hold it in the open air or breathe gently on it. Tiny white frost crystals will form on the cold metal. Let children observe how fast the f...

  Scientific Explanation: Iron rusts when it reacts with oxygen and water in the air. This reaction forms a new substance called iron oxide, which we see as orange or brown rust. Rust makes iron weaker because the metal slowly breaks down. Moist places make rust form faster because they have more water in the air. This process is an example of a slow chemical change. Child-Friendly Explanation: Iron objects can change color when they stay in rain or water. The metal mixes with air and water, and it slowly turns orange and crumbly. It’s like the metal is getting old and tired. That orange color is called rust! Open-Ended Questions: -Where have you seen rusty metal before? What do you think caused it? -How long do you think it takes for rust to form? Why? -What changes can you see on the metal when it starts to rust? Hands-on Activity: Take children outside or around the classroom. Ask them to look for metal objects: door handles, fences, bicycle parts, chair legs, etc. Let them gues...

Scientific Explanation: Flowers need water, sunlight, and air to stay healthy. When a flower does not get enough water, it loses moisture from its petals and stem. This process is called dehydration. Without water, the cells inside the flower shrink, and the petals become soft, dark, and dry. This shows how important water is for keeping plants alive and beautiful. Child-Friendly Explanation: Flowers are like living friends. They need to drink water to stay happy! When they don’t get enough, their petals become dry and fall down. Just like we need food and water every day, flowers also need care to stay bright and strong. Open-Ended Questions: -Why do you think flowers change when they don’t get water? - How can we help flowers live longer? -What do flowers need to stay healthy? Short Hands-on Activity:  Give children two flowers. Put one in a cup with water and the other in an empty cup. Ask them to guess which flower will stay colorful longer. Over a few days, let them observe t...
