A simple explanation for 5-year-old kids about how flippers help animals swim better than legs.
Have you ever seen a seal or a penguin? They are special animals that live in the water, and guess what? They have flippers instead of legs!
Flippers are like wings, but they are used for swimming instead of flying. They help animals move through the water quickly and easily. Imagine how difficult it would be to swim if you had legs like us!
1. Shape: Flippers are wide and flat, which gives them a big surface to push against the water. This helps the animals go really fast!
2. Movement: When animals swim with flippers, they can move their bodies smoothly. They can go up, down, and turn quickly. Legs would make it harder to do all of these things.
3. Balance: Flippers help animals keep balance in the water. They can glide through the water without tipping over, just like a boat!
So, having flippers instead of legs is much more practical for animals that live in the water. It helps them swim better and stay safe. Isn’t that cool?
