Weather Experiments for Kids by Topic
These weather experiments are grouped by key science concepts to make learning easier and more meaningful.
Cloud and Rain Experiments
These experiments help kids understand how clouds form and why rain falls.
Rain Cloud in a Jar
Create a cloud using shaving cream and watch rain fall through it. This model shows how clouds hold water until they become too heavy and release precipitation.
Cloud in a Jar
Make a real cloud inside a jar using simple materials. This demonstrates how water vapor condenses into tiny droplets to form clouds.
How Does Rain Form
Explore how water builds up in clouds and falls as rain. This activity helps explain the process of precipitation in a simple, visual way.
Cloud Viewer Activity
Head outside to observe and identify different types of clouds. This builds observation skills and connects experiments to real weather.
Wind and Air Experiments
These activities show how moving air creates wind and affects weather patterns.
Tornado in a Bottle
Create a spinning vortex to model a tornado. This demonstrates rotating air currents and helps explain how tornadoes form during storms.
DIY Anemometer
Build a simple tool to measure wind speed. This shows how scientists track and study wind in real life.
Wind Vane
Make a wind vane to track wind direction. This helps kids understand how air moves in different patterns.
DIY Windmill / Wind Turbine
Build a wind-powered model to explore how moving air can generate energy.
Temperature and Air Pressure Experiments
These experiments explore how temperature and pressure changes affect weather.
DIY Thermometer
Create your own thermometer to observe temperature changes throughout the day. This helps kids understand how temperature is measured.
DIY Barometer
Measure changes in air pressure with a simple model. This shows how pressure changes can signal weather shifts.
Hot and Cold Air Experiment
Compare how warm and cool air behave differently. This demonstrates how temperature affects air movement.
Balloon and Jar Air Pressure Experiment
Use a balloon and jar to see how air pressure changes affect objects. This helps explain how pressure influences weather systems.
Temperature Tracking Investigation
Take temperature observations further with a simple investigation.
Track temperature at different times of day or in different locations (sun vs. shade) and compare your results.

This activity helps kids:
- collect real data
- identify patterns
- understand how the sun affects temperature
Storms and Weather Energy
These activities help kids explore powerful weather forces like storms.
Lightning (Static Electricity Experiment)
Create static electricity to model how lightning forms. This shows how energy builds up and releases in the atmosphere.
Light and Energy Experiments
These experiments show how sunlight plays a role in weather.
Shadow Tracking Experiment
Track how shadows change throughout the day using the sun. This shows how Earth’s rotation affects sunlight and helps explain changes in time and seasons.
💡 Shadow length and direction change throughout the day and across seasons as the sun’s position shifts.
Rainbow Experiment
Use water and sunlight to create a rainbow. This demonstrates how light bends (refraction) to form colors.
Solar Oven Experiment
Use sunlight to heat food and explore solar energy. This shows how the sun transfers heat to Earth.
Water Cycle and Weather Patterns
These activities explain how water moves through the environment.
Water Cycle for Kids
Explore evaporation, condensation, and precipitation. This helps connect weather events to the larger water cycle. Winter water cycle variation here.
DIY Rain Gauge
Measure how much rain falls over time. This introduces data collection and real-world weather tracking.
Build a Homemade Weather Station
Take your weather experiments further by building a simple weather station to track real data over time.
A weather station combines tools like a thermometer, rain gauge, wind vane, and barometer to help kids observe daily weather changes—just like real meteorologists.

Weather Science Concepts for Kids
These experiments help explain:
- Water Cycle: evaporation, condensation, precipitation
- Wind: air moves from high to low pressure
- Temperature: the sun heats Earth unevenly
- Clouds: formed from water vapor in the air
- Air Pressure: changes in pressure affect weather patterns
Weather and Seasons
Weather changes throughout the year, and these changes are connected to the seasons.
As Earth orbits the sun, different areas receive varying amounts of sunlight, which affects temperature, weather patterns, and daylight hours.
