  • Scissors
  • Straw or thin coffee stirrer (for barometer)
  • Tape
  • Ruler

  • Optional: Thermometer
  • Optional: Materials for a rain gauge (e.g., straight-sided clear container, ruler, waterproof marker)
  • Optional: Camera or smartphone for recording weather forecast video

Welcome Future Meteorologist, Aria!

Get ready to dive into the amazing world of weather! Today, we're going to become weather detectives, uncover the secrets of the sky, and even try to predict what's coming our way. Pack your curiosity, and let's begin!

Part 1: Cloud Gazing Detective (Approx. 45 minutes)

Clouds aren't just fluffy white things in the sky; they're storytellers! They can tell us a lot about the weather. Let's learn to read their stories.

  1. Cloud Research: Using the internet (search for "types of clouds for kids" or "NOAA cloud types"), research the main types of clouds:
    • Cirrus (High, wispy)
    • Cumulus (Puffy, cotton-like)
    • Stratus (Flat, grey sheets)
    • Cumulonimbus (Tall, dark, stormy!)
    For each type, find out: What do they look like? What kind of weather do they usually bring? Draw a picture of each in your notebook and write down your findings.
  2. Sky Spy: Go outside and observe the clouds today. What types do you see? Sketch them in your notebook and try to predict today's weather based on your cloud research.

Part 2: The Pressure is On! (And Off!) (Approx. 60 minutes - including instrument build)

Did you know that air, even though it's invisible, has weight? This weight creates air pressure, and changes in air pressure are a big clue for weather forecasting!

Activity: Build a Homemade Barometer!

A barometer measures air pressure. When air pressure is high, it usually means good weather. When it's low, stormy weather might be on its way!

Materials for Barometer (also listed above):

  • Wide-mouthed glass jar
  • Balloon
  • Strong rubber band
  • Scissors
  • Straw or thin coffee stirrer
  • Tape
  • A piece of paper and a pencil

Instructions:

  1. Cut the neck off the balloon to make a flat sheet of rubber.
  2. Stretch the balloon tightly over the mouth of the jar and secure it with the rubber band. Make sure it's airtight! This creates a diaphragm.
  3. Tape one end of the straw to the center of the balloon diaphragm, so the straw sticks out horizontally. This is your pointer.
  4. Place the jar next to a wall. Tape a piece of paper to the wall behind the free end of the straw.
  5. Mark the current position of the straw's tip on the paper. Label it "Start."
  6. How it works: When the air pressure outside the jar increases, it pushes down on the balloon diaphragm, making the straw point upwards. When the air pressure decreases, the air inside the jar (which is at a stable pressure) pushes the diaphragm up, making the straw point downwards.
  7. Observe your barometer over the next few days. Mark the straw's position each day. Does it go up or down? What's the weather like when it changes?

Think About It: Research online: What is "high pressure" and "low pressure" weather? How does this relate to your barometer?

Part 3: Weather Watcher's Log (Ongoing - 15 minutes per day for 3 days)

Now it's time to become a true local weather expert! For the next three days, you'll keep a weather log.

In your notebook, create a chart with these columns for each day:

  • Date & Time
  • Temperature (if you have a thermometer)
  • Cloud Types Observed (use your knowledge from Part 1!)
  • Wind (calm, breezy, windy? Direction if you can tell)
  • Precipitation (rain, snow, hail, none)
  • Air Pressure (Note your barometer reading: "straw up," "straw down," or "straw same")
  • Your Prediction for the Next 24 Hours

Try to check and record the weather at the same time each day.

Part 4: Aria's Awesome Weather Forecast! (Approx. 60-90 minutes)

After your three days of observation and with all your new knowledge, it's time to create your own weather forecast!

Your Mission:

  1. Analyze Your Data: Look at your weather log. What patterns did you see? How did the clouds, air pressure (your barometer!), and temperature change?
  2. Check the Pros: Briefly look up the official weather forecast for your area for the next day. How does it compare to what you might predict based on your observations?
  3. Create Your Forecast: Prepare a short (1-2 minute) weather forecast for your local area for the *next* day. You can:
    • Write a script and present it.
    • Draw a weather map with symbols and explain it.
    • Film a short video of yourself giving the forecast (like a TV meteorologist!). Be creative and have fun!
  4. What to include in your forecast:
    • Predicted high and low temperature (you can estimate or use official data for this part if you don't have a reliable thermometer for precise readings).
    • Expected cloud cover.
    • Chance of precipitation.
    • Any interesting weather facts you learned!

Present your forecast to your family or record it!

Wrap-up & What's Next?

Great job, Meteorologist Aria! You've explored clouds, air pressure, and made your own forecast! Weather is a fascinating and ever-changing subject. If you enjoyed this, you could explore:

  • Extreme weather (hurricanes, tornadoes, blizzards)
  • Climate change and its impact on weather
  • Building other weather instruments (like a rain gauge or anemometer)
  • Careers in meteorology

Keep observing the sky – it has so much to tell you!
