What do a crazy hair day, a wooden door stuck in its frame, and the weather have in common? Humidity! In this fun hands-on weather lesson students explore surprising information about human hair, the air around them, and the weather by building a hygrometer from a strand of hair, a straw, a wooden panel, and two nails. A great way to make humidity visible! Read more

What are cold fronts and warm fronts? What happens when a cold front meets a warm front? You can test this using different temperatures of water. Use food coloring to label the cold and hot water, then carefully combine the two liquids together. What happens? How do they mix? You can also fill water balloons with hot or cold water, and then float in a hot or cold water bath. How does temperature affect the movements of the balloon? You can do similar experiments with hot and cold air in… Read more

Wind is a part of our everyday weather. Its strength can range from a soft breeze to a violent storm. In this lesson, students learn how to measure wind speed by building anemometers (wind speed meters) from paper cups and straws and experimenting with them. Read more

Wind can make a cold day colder, or a hot day more pleasant. Use weather data to test the effect of wind on the temperature. How much of a change on the perceived temperature can the wind make? How is wind shear calculated? How can a wind barrier, like a wind breaker, keep you warm even if there is no insulating material? Build an instrument to measure wind speed or direction.

Students learn the difference between global, prevailing, and local winds. They make wind vanes out of paper, straws, and soda bottles and use them to measure wind direction over time. They analyze their data to draw conclusions about the local prevailing winds.Engineering Connection Understanding the patterns and behavior of global and localized winds enables engineers to design technologies that protect us from wind and exploit the energy of wind. Engineers design… Read more
