Participate in three activities that look at the earth's limited water supply and the changes water goes through as it enters each phase of the water cycle. The resource is complete with three activities that demonstrate the changing...

Dive into a lesson on the hydrosphere with this Powerpoint presentation. Building on prior knowledge of the water cycle, young scientists learn what happens to water after it falls as precipitation and explore the...

Did you know that California produces two thirds of the fruits and nuts consumed in the United States? That it produces almost one third of the vegetables? Did you know that scientists warn that California is facing the onset of a...

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

Fifteen million children under the age of five die each year due to diseases in their drinking water. Water pollution is the topic of lesson 34 in the series of 36. Scholars, through reading and discussing, study numerous aspects of...

According to the Mauna Loa observatory, carbon dioxide levels increased by 3 ppm in our atmosphere between 2015–2016. Individuals analyze carbon dioxide data from around the world and then share this with a home group in lesson...

Students study the amount of potable water on the Earth. In this water lesson, students examine the amount of potable water as compared to all the water on the Earth. They discuss why many parts of the world do not have access to good...

What is reflectivity, and what does it have to do with the Earth's climate? As reflectivity is measured by albedo, scientists can gather information on Earth's energy balances that relate to global warming or climate change. Budding...

Krill is a very small ocean animal that is key to keeping the ocean ecosystem going. The class reviews food webs and chains, learns about the importance of krill, discusses krill anatomy, builds a model of a krill, and then has a...

Dry ice is extremely cold — it is -109.3°F or -78.5°C. Scholars observe and explain the molecular motion associated with melting. Then they design their own experiments to speed up the melting process. Finally, a teacher presents a...

A fish that lives in the desert? You and your class can meet the desert pupfish as they examine its habitat, the role humans play in diminishing water supplies, and how climate change might impact this fishy friend. There are four short...

Explore the amazing power of glaciers with a hands-on earth science experiment! After first learning basic background information, learners go on to create their very own chunks of frozen water and gravel in order to...

If the majority of our planet is covered with water, why do we need to bother conserving it? With a thorough and varied investigation into the location and types of water on the earth, learners will gain an understanding of why this...

Students are introduced to the components and importance of the water cycle. They are shown how groundwater moves using a model. Students list 9 places on earth where water is found. They define the terms cycle and water cycle.

A truly hands-on and inquiry based learning activity bridges all the lessons in the series together. Beginning with a discussion on average global temperatures, young meteorologists use real-world data to analyze climate trends in order...

Students analyze density. In this density lesson, students experiment with floating an egg. Students discover that salt added to water changes the density of the water allowing an egg to float.

First graders drop items into water, and discuss why some things float and others sink.

Students comprehend how satellites use remote sensing to produce images. They use supervised classification with Landsat images. Students recognize that the earth's surface has different basic land surfaces that reflect/emit different...

Eighth graders are introduced to the Earth's hydrologic system including the cycling of water in the atmosphere and the movement of water on the surface of the planet using the Great Lakes watershed as an example.

Students explore the states of water. In this water states lesson plan, students observe ice over time and the changes that take place. Students read a related text and draw their observations in a journal entry. Students discuss the...

How is sea coral like a thermometer? Part three of a six-part series from NOAA describes how oceanographers can use coral growth to estimate water temperature over time. Life science pupils manipulate data to determine the age of corals...

"Waiting to Move," a photo essay by Ciril Jazbec, brings into sharp focus the threats posed by climate change. Class members examine images of Shishmaref Island and the Native Alaskan Inupiate coastal villages that are impacted by rising...

Students are introduced to the processes of evaporation and condensation as they observe physical changes in water. They observe how matter changes from a solid to a liquid state. Students are explained that steam is water in its gaseous...

Students perform experiments measuring water pressure. They record their observations after poking holes in plastic bottles filled with water with the lids on and then off. They discover the role gravity plays in the water flow.
