How to Make a Weather Station for Your Window

Create a simple weather station with your kids using everyday materials to track temperature, humidity, and weather patterns.

1. Gather Your Materials. You'll need a clear plastic bottle, a balloon, a rubber band, a straw, tape, a piece of cardboard, markers, an outdoor thermometer, and a small container for rain collection. Most of these items are probably already in your home. The outdoor thermometer is the only item you might need to purchase, and you can find basic ones at any hardware store for under $10.
2. Make a Barometer to Measure Air Pressure. Cut the neck off a plastic bottle and stretch a balloon tightly over the opening. Secure it with a rubber band. Tape one end of the straw to the center of the balloon, making sure it extends out like a pointer. Tape a piece of cardboard behind the straw and draw a scale with 'High' at the top and 'Low' at the bottom. When air pressure increases, the balloon pushes down and the straw points up. When pressure decreases, the balloon pulls up and the straw points down.
3. Set Up Your Thermometer. Attach your outdoor thermometer to the outside of your window or place it on a windowsill where it won't get direct sunlight. Direct sun will give you false readings that are much higher than the actual air temperature. If you only have an indoor spot, try to place it near a window that stays shaded most of the day.
4. Create a Rain Gauge. Use a clear, straight-sided container like a mason jar or plastic container. Place it outside your window or on a balcony where it can catch rainwater without being blocked by overhangs. Use a ruler or draw measurement lines on the side with a permanent marker so you can easily read how much rain has fallen.
5. Make a Weather Tracking Chart. Create a simple chart on paper or cardboard with columns for date, temperature, barometer reading (high/medium/low), rainfall, and general weather observations. Include space for kids to draw pictures of clouds or weather conditions they see. Post this chart near your window weather station so it's easy to record daily observations.
6. Start Your Daily Weather Routine. Check your weather station at the same time each day - morning works well and helps start the day with a fun science activity. Record the temperature, check whether your barometer is pointing high or low, measure any rainfall from the previous day, and empty the rain gauge. Have your kids look outside and describe what they see - sunny, cloudy, windy, or stormy skies.
