August
Cool down with water! Run through a sprinkler, take a swim in a pool, visit the beach, spray yourself down using a squirt bottle.
Play in the sand! Visit the beach, a playground, or your backyard. Build a sandcastle or write your name in the sand.
Fun with bubbles! Blow bubbles and see how many you can catch or pop!
Play on the playground equipment at your school or local playground! Climb ladders, swing on a swing, slide down the slides, etc.
Help your family have a barbeque - shuck the corn, gather condiments, fold the napkins, etc.
