Curated OER
Hands-On Humidity
Students examine why humidity changes throughout the day. They study the concept of relative humidity, absolute humidity, and dew point temperature. They interpret phase diagrams and explain why relative humidity typically falls and...
Curated OER
The Drinking Bird
Students discover how the "drinking bird" functions. In this investigative lesson, students discover what makes the drinking bird drink by analyzing relative humidity, temperature, and barometric pressure.
Curated OER
Dripping Wet or Dry as a Bone?
Students use a sponge and water model to explore the concept of relative humidity and create a percent scale. They define humidity and saturation, build a simple humidity/saturation model, collect, predict and interpret data, and create...

Do Cities Affect the Weather? (Making a Cloud in a Bottle)
The dynamics of a city can have a drastic effect on the weather. A hands-on lesson asks learners to build a model to illustrate how city pollution provides a nucleus for condensation. The greater the pollution, the greater chance for...
Curated OER
Weather Variables Lab
Students examine what happens when air temperature drops and gets closer to the dewpoint. They perform a lab activity which illustrates the effects on humidity, precipitation and barometric air pressure.

How Clouds Form
Young scholars analyze how clouds form. In this cloud formation lesson, students brainstorm types of clouds and what they think they're made of. Young scholars conduct an experiment to see how clouds form and discuss their observations....
Curated OER
Storm That Drowned a City
Students use a map to locate New Orleans and watch a video on the destruction of Hurricane Katrina. As a class, they watch a demonstration on how a wetland can reduce the impact of a hurricane. In groups, they perform their own...
Curated OER
Condensation
Middle schoolers explain how water changes from vapor to liquid with a change in temperature by engaging in this experiment. They use a worksheet imbedded in this lesson to guide their inquiry.
Curated OER
Global Water Cycle & Heat Flow
Students experiment to discover how different variables affect the water cycle. They do hat flow experiments and construct a computer heat flow model.
Curated OER
Surface Meteorological Observation System (SMOS)
Students monitor local surface weather conditions for at least 30 days. They interpret the data by graphing it and detemining percentages.
Curated OER
Nature's Air Conditioner
Students observe the process of transpiration in leaves. They measure how much water a leaf gives off in a 24-hour period, calculate the volume, and answer discussion questions.
