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...

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,...

The Alaskan wilderness contains every imaginable element of the water cycle: it has flowing streams, cool spring rain, and frozen glaciers. Pupils use a series of worksheets to identify and define evaporation, condensation, and...

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...

To prepare for a performance task assessment, class members review the stages of the water cycle and then individuals assume the roles of drops of water for a Reader's Theater exercise. The script, a graphic depicting the water...

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,...

Young scientists transform themselves into rivers, oceans, clouds, and drops of water in order to explore the water cycle. After assigning and explaining to students their different roles in the activity, the teacher reads aloud a...

Here's a wonderful activity on how substances change states. Groups of learners are given trays with a chocolate bar, a piece of paper, an ice cube, and a balloon. During the activity, the groups closely observe the changes that each...

Fourth graders identify a physical change as one that results in a change in size, shape, or state of matter. After an initial teacher-led discussion and demonstration, groups of students get together to perform an experiment which...

Take young scientists on a trip through the water cycle with this interactive science activity. After setting up a series of ten stations representing the different places water can be found, children use the included printable dice...

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...

Plasma is the most common phase of matter in our universe. Scholars explore the change of energy as molecules change phases of matter. They rotate through stations, graphing the changes in energy level.

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...

Here is part one of a two-part instructional activity in which scholars investigate the changing states of water—liquid, solid, and gas. With grand conversation and up to three demonstrations, learners make predictions about what they...

Here is part two of a two-part instructional activity in which scholars investigate the changing states of water—liquid, solid, and gas—and how energy from heat changes its molecules. With grand conversation, two demonstrations, and...

Encourage peer collaboration and assist with the creation of visual aids to identify carbon, water, and nitrogen cycles as your class learns more about nature. They discuss relative information, create a visual aid...

Rain, rain, go away—wait, there it is again! Elementary scientists learn how rain works its way through the stages of the water cycle with a series of classroom lessons and hands-on activities.

Through a PowerPoint presentation and the embedded animation and video, earth science enthusiasts find out about the moisture in the soil beneath our feet. In the animation, follow a water molecule on its path through the water cycle. As...

Your class sets up a mini water cycle model to examine the process. Then they watch an animation, following a water molecule through the cycle. A well-developed lab sheet guides learners through the lesson and a PowerPoint presentation...

Open learners' eyes to the challenge of finding safe drinking water – something we often take for granted in our country. The PowerPoint presentation includes images, graphs, diagrams, and even a video to stimulate discussion on how we...

Environmentalists test stream water for temperature, pH, and turbidity. Each group shares their information and then the class makes an overall evaluation of the water quality. A slide show sets the backdrop for the teaching portion and...

An excellent instructional activity on the water cycle! In it, learners should gain a general understanding of the water cycle, along with how water first falls as precipitation, then ends up coming out of our faucets. This instructional...

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...

Equip young campers with important survival knowledge with a set of engaging lessons. Teammates work together to complete three outdoor activities, which include building a shelter, starting a campfire, and finding directions in the...
