Wet Air

Students create psychrometers to measure the humidity of the air.  In this meteorology activity, students make a wet-bulb thermomter and place it next to a dry-bulb thermometer to measure the relative humidity in the room.

Explore the impact of wildfires with a reading passage about ecosystems. Pupils read the passage and respond to five questions related to the content of the text.

A slide show serves as the backdrop for a lesson on the moisture in Earth's atmosphere. Through it, mini meteorologists learn about the attributes of the atmosphere and actually use data-collecting weather tools to make observations and...

Fahrenheit? Celsius? What's the difference, and where did these two temperature scales originate? Your pupils will learn all about these topics by reading the passage included here. After reading, individuals respond to five questions...

Students measure humidity in the classroom. In this weather lesson, students use a psychrometer to measure the humidity in the classroom. Students complete a lab packet.

A hydrophobic substance (water hating substance) is added to differently colored sand which means that when the sand is dumped into a bowl of water, it doesn't get wet - at all! This is an impressive trick, and is easy to do. All you...

Nearly 400 years have passed since the thermometer was first created! But guess what? The principles are still the same. It works based off of expansion and contraction. Have small groups create thermometers and test them out in...

Using the wet bulb-dry bulb method, students will compare the temperature of a dry temperature sensor and a wet temperature sensor. By comparing the temperatures, students will be able to find the relative humidity. After completing the...

Students use a sponge and water model to explore the concept of relative humidity and create a percent scale.

Learners 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...
