Answer: Cotton is a special type of fabric that helps keep us cool when it is hot outside. Here's how it works:
Example 1: When you wear a cotton t-shirt on a hot day, it helps you feel cooler because it lets air in and takes away sweat.
Example 2: A pair of cotton shorts can keep you comfy while playing outside because they are light and help keep you dry.
Example 3: A cotton hat can protect your head from the sun and keep your head cool while you are at the park.
Fun Fact: Cotton comes from the cotton plant, and it is grown in warm places. That's why we often use it for summer clothes!
