Changing State: Condensation
When you have a cold drink and you notice the water forming on the outside, it is literally pulling the water from the surrounding air to form the condensation. After watching a demonstration of condensation forming on a glass,...

Condensation
It's time to break the ice! If you are doing all of the lessons in the unit, children have already seen that increasing heat increases the rate of evaporation, but is the opposite true? Does decreasing temperature cause more condensation...

Heat Transfer and Cooling
Astronauts train underwater to simulate the change in gravity. An out-of-this-world unit includes three hands-on activities, one teacher demonstration, and a discussion related to some of the challenges astronauts face. Scholars apply...

Condensation Station
Where does the water come from? Pupils conduct an experiment to learn more about condensation. Scholars fill two cups with ice water and isolate one from the surrounding air. They then use a coffee filter to compare the amount of water...

Evaporation Sensation
Where did the water go? Learners conduct an experiment to see how the difference in temperature affects evaporation rates. Scholars continue to investigate evaporation by comparing water and alcohol evaporation rates. Pupils experiment...

What Is the Water Cycle?
Small groups place sand and ice in a covered box, place the box in the sunlight, then observe as evaporation, condensation, and precipitation occur. These models serve as miniature water cycles and demonstrations of the three phases of...

The Water Cycle
Young scientists get their feet wet as they learn about the water cycle in this series of activities. Whether they are observing how evaporation causes puddles to dry up, or how plants put water into the atmosphere through...

Solar Distiller
Explore the sun's ability to distill contaminated water with this simple set of classroom experiments. After filling two glass bowls, one with muddy water and the other with salt water, they are covered with plastic wrap and placed...
Virginia Department of Education
Heat and Thermal Energy Transfer
How does radiation affect our daily lives? Answer that question and others with a lesson that discusses radiation and its use in thermal energy transfer through electromagnetic waves. Pupils investigate vaporization and...

Weather Stations
Transform your classroom into a fully functioning weather station with this series of hands-on investigations. Covering the topics of temperature, precipitation, wind patterns, and cloud formation, these activities engage young...
National Wildlife Federation
The Water Cycle
Observe the water cycle from the comfort of your classroom with this excellent earth science experiment. Working collaboratively, young scientists first create terrariums complete with hills, plants, lakes, and an...

The Cycle of Water
Young water cycle enthusiasts discover the water they have been using has been cycling around the earth for billions of years. Through presentations, learners will understand that water has three states and how these forms...

Smoke on the Water
How do clouds form? Learners demonstrate the formation of clouds and the water cycle by testing four different setups in a plastic bottle. They identify the key components of a cloud to help them understand the process of cloud...

What is the Water Cycle?
Dive into an exploration of the water cycle cycle with this simple earth science lesson. After first discussing where rain comes from, young scientists define the terms condensation, evaporation, transpiration,...

The Hydrologic Cycle
There is the same amount of water on earth now as there was when it was formed. The water from your faucet could contain molecules that dinosaurs drank! Young scientists build their own hydrologic cycle model and observe...
