Hi friends,
The spring season brings many types of weather: warm sun (like we had this weekend), wind, rain, and sometimes snow or hail.
You already gather information about the weather to help you decide what to wear or to do outside. By building your own weather station, you can track smaller changes in the weather each day!
To track the weather at your house, make a calendar with the days of the week and space to draw a picture of the weather and write your observations about the amount of rain/snow/hail that fell, the temperature, and anything else you notice about the clouds, the wind, or the sun.
Precipitation
Place a clear jar or cup outside to measure how much rain/hail/snow fell in the last 24 hours. Use a ruler and tape to mark out every 10 centimeters for measurement.
Temperature
If you don't have an outdoor thermometer, you can use a clear jar or cup filled with water to observe changes in the temperature. Try touching the water at different times during the day. Is your cup of water colder in the morning or afternoon? Did the water freeze overnight? What clothes are you wearing today: shorts and a t-shirt or pants and a jacket? Do you feel warm or cold?
Wind
When you go outside, can you feel the wind blowing on your face? Do you see the clouds or tree branches moving? Where do you think the wind is coming from? You can build a simple weather vane to observe the direction the wind is blowing.

Materials: cardstock or cardboard, scissors, tape, stick, pen |
|
Cut the cardstock into an arrow (make the tail bigger than the tip)
and tape a pen cap onto the back of the arrow.
Cut out a square and draw a compass with north, east, south west. |
|
Find a spot outside that's open to the wind.
Place your stick through the center of the compass into the ground.
Have a parent help you line up north on your compass with true north.
Place the pen cap and arrow on top of the stick.
The arrow will move to point in the direction the wind is coming from. |
*Note: You may want to make your weathervane with a waterproof material or cover the cardstock with tape to "laminate" it
Sun and Clouds
Go out to your weather station and look up at the sky! When the sun is shining, you can look for shadows. Do you see your shadow? Can you make fun shapes with your shadow? What other shadows do you see?
Do you see any clouds in the sky? What do they look like? Do they remind you of anything? Clouds show us information about the upcoming weather.
|
Are they light and wispy and high in the sky? It's probably going to be a nice day.
|
|
Are they big and puffy like cotton balls? When these clouds turn grey they are starting to fill up with water |
|
When clouds grow very big and dark they can become storms with thunder and lightning. |
|
Does it look like there is a low blanket of grey cloud covering the sky? These clouds often produce rain or snow. |
|
Does is look like you're in a cloud? Fog is a cloud near the ground

You can make weather observations at the same time of day or many times during the day and record them on your weather calendar. I hope you have fun observing the weather this week! I'll be sharing my observations on Friday and I hope you will share yours too.
