When you tap a domino, it falls and knocks over the next one. This is like a cause. The first domino falling is the cause, and the next domino falling is the effect. Without the first tap, the rest wouldn’t fall. Just like when you smile at someone, and they smile back. Your smile is the cause, and their smile is the effect.
Think of a seed planted in the ground. When you water it and give it sunlight, it grows into a plant. The water and sunlight are the causes, and the plant growing is the effect. If you don’t water it, the plant won’t grow. It’s like when you eat your veggies and you grow strong. Eating veggies is the cause, and growing strong is the effect.
Imagine a puzzle. Each piece you place is a cause, and the beautiful picture you see when it’s done is the effect. If you don’t put the pieces together, the picture won’t appear. Just like when you practice drawing, you get better. Practicing is the cause, and getting better is the effect.
