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...

Curious physical scientists follow a lesson on the properties of water with this lesson on distillation. They observe a miniature water cycle model that filters dirty water into clean water. These two lessons combined are an enriching...

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...

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...

Join the tree house detectives in learning about the processes of the water cycle, water conservation, water treatment, and water as a limited resource.

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...

Keep within a water budget. Learners find out that less than 2.5% of Earth's water is available to drink—and that there is a fixed amount of water. Scholars read an interesting article comparing the available water to a game of Monopoly...

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,...

Environmental explorers examine the campus and take note of living organisms. Introduce them to the biosphere and the questions of the day: How much water can be found in the biosphere? A slide show helps you along, and even contains a...

You've heard of farm to table ... but what about farm in classroom? Junior agriculturalists embark upon a two-week journey into the science of growing things. Based upon the classic terrarium in a two-liter experiment, the lesson goes...

As a stand-alone or as part of the intended unit, this is a valid investigation of what causes condensation to occur.  By limiting the amount of air around a cold cup of water and comparing it to one out in the open, they find that...

Here's a wonderful lesson 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...

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...

The earth has a love-hate relationship with carbon. Learners complete a series of nine lessons that begin with an examination of the role of carbon in Earth's systems. They then relate changes in climate and weather to changes in the...

Don't desert a resource on the desert! Scholars work in groups to build on their ideas from the previous lesson to design a sustainable guest village in the Saguaro National Park. Each group produces a PowerPoint presentation to share...

What better way to make predictions about future weather and climate patterns than with actual climate data from the past? Young climatologists analyze data from 400,000 to 10,000 years ago to determine if climate has changed over...

In the summer of 1815, snow fell every month in New England. Was this related to the volcanic eruption of Tambora in Indonesia earlier in the year? Young scientists design their own experiments to research the long-term effect a volcanic...

Is your class in the dark about photosynthesis? Shed some sunlight on an important biological process with a thoughtful activity. After answering questions to help determine their level of knowledge, learners work with chemical equations...

Note the way that plants change during the season by adopting a plant on your school campus. After your class chooses their plant, they research the plant's needs, how it differs from other plants, find ways to support their plant's...

This is one in several lessons that explore the relationship between temperature and phase changes of water. After some discussion, elementary physical scientists place wet paper toweling on a hot and a room-temperature water bag...

Class members explore the carbon cycle in the final installment of the 10-part Discover Your Changing World series. They play a simulation game where they walk through the steps carbon takes as it cycles through the different layers...

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...

Focused little scientists will flitter their arms back and forth across the room with excitement as they learn the life cycle of a butterfly and how living things grow and change over time.
