A beach blanket is a big flat cloth you lay out so your bottom doesn't touch the hot, scratchy sand. It also gives the whole family a clean spot to share snacks.

Beaches are some of the windiest places around because there are no trees to block the breeze. That strong steady wind is just what a kite needs to soar high.

Sandwiches are an easy picnic food — you just put filling between two slices of bread and wrap them up. They don't need heating, so they travel well from home to the park.

The ocean is an enormous body of salt water that covers most of the Earth. It is home to more kinds of fish than any pond, river, or lake.

Bikes (short for bicycles) have two wheels and pedals that you push with your feet. Riding them around the park is a favorite way to have fun and get exercise.

Shells are the hard homes that snails and clams leave behind after they are gone. Waves wash them up onto the shore, where kids love to collect the prettiest ones.

Wind is air that is moving fast, and a strong gust can lift a hat right off your head. You can't see the wind, but you can feel it and watch it push trees and leaves around.

Lemonade is made by mixing fresh lemon juice with water and sugar, then adding ice. The sweet-and-sour flavor tastes extra good when you are hot and thirsty from playing.

Fireflies only light up when the sky is dark, because their tiny glow would be invisible during the day. That's why they come out at night, flashing like little yellow-green stars.

Think about where each item protects or covers you: umbrella overhead for shade, swimsuit covers your body in water, sunglasses sit on your eyes, and flip-flops slide onto your feet.
