"Key Roles of WBCs"

White blood cells are key immune defenders.

create a rainbow

Rainbow appears after summer rains because sunlight is refracted, scattered, and reflected by water droplets in the atmosphere, creating a spectrum of colors. The water droplets act as tiny prisms, separating sunlight into its component colors and forming a beautiful color arc that we see as a rainbow. To create a water rainbow, you can use a garden hose or sprayer to create a mist of water droplets. Stand with your back to the sun and mist the water into the air at a low angle. If the sunlight is at a direct angle and there are enough water droplets in the air, you may see a rainbow form. Playing with water droplets and sunlight can be an interesting and magical way to create your own mini rainbow. Just remember: you need a source of sunlight and enough water droplets in the air to see the colors of the rainbow.
