Rainy Days

  Get the kids outside on a rainy day. Allow them to collect rain in buckets and then measure the amount of rainfall received. Splashing around in puddles provides children with the exercise needed to stay healthy. Allow children to get muddy. Molding mud into shapes helps stimulate and improve small motor functions. Record how the rainfall stimulates the five senses (see, smell, taste, touch and hear). After the rain stops, observe the ground and plants and discover which worms and insects become visible.
  
  

Snow Days

  Tie a piece of white cloth to a short stick and hide it in the snow. Divide participants into groups and see which group finds the flag first. Repeat the activity several times to determine a winner. Instead of an egg hunt, host an ice cube hunt. Hide ice cubes in the snow and see how many each participant can find. Allow limited time so the ice cubes may be counted before they melt. Build a snowman and play a snowman hat toss game. Obtain several weather resistant hats. Toss the hats toward the snowman and try to "ring" the snowman's head.

  Fly various types of kites on a windy day. Observe which ones fly higher and steadier than others. Observe and record sounds such as rustling leaves, whispers and whistling noises. Try to locate the source of the sounds. Fly paper planes inside and then fly them outside. Record how the wind affects the planes. Take an umbrella outside and observe the force of the wind and how the wind changes direction.
  
  

Sunny Days

  Get out in the sunshine and organize relay races and backyard ballgames. Set up a volleyball or badminton net and host a tournament. Get into swimsuits and run through water sprinklers. Provide a shaded area for rest and cooling down, and provide healthy snacks and water. Play on the driveway or sidewalk with colored chalk or clay. Make Sun Clay from water, salt and cornstarch. Sun Clay doesn't dry out in the sun like other molding clay mixtures. Get the whole family involved and plant a garden. Plant a variety of flowers that bloom all summer long and observe their reaction to different weather conditions.
