What impact do humans have on greenhouse gas emissions? What are the natural causes of these gasses? Thanks to the carbon cycle, carbon dioxide eats away at the earth's atmosphere with the intensified help of humans. Young scientists...

The fifth installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program defines dead zones and how they form. Pupils then examine data from the Gulf of Mexico to determine dead zone formation.

After reading an article about irrigation on Canadian farms, learners participate in a discussion. They individually write an opinion paper about the surrounding issues. A lesson like this can be used in an earth science class when...

Fourth graders create a biome of their choosing in a terrarium. Terrariums are observed and results recorded daily for 2 weeks. They observe/record changes in the water within their terrarium and use the data to write sentences...

Incorporate art and poetry into an early elementary science lesson about cloud formation. With fun and engaging activities that follow a natural learning progression, youngsters will develop key vocabulary and conceptual understanding...

Students study the water cycle including condensation, evaporation, and precipitation. In this water cycle lesson, students watch a video and access assigned web sites to investigate the water cycle. They complete an experiment with a...

Learners discuss and interpret background knowledge on poster copy given on the water cycle. Students complete the included activity sheets using the poster as a reference in small groups. Learners identify and name where water can be...

Fifth graders study the water cycle. In this science lesson plan, 5th graders distinguish among evaporation, condensation, and precipitation phases of the water cycle.

Learners investigate the water cycle. They observe a demonstration of the water cycle involving ice, water, bowls, and steam, explore various websites, and listen to the book, "The Magic School Bus: Wet All Over: A Book About the Water...

Students investigate how the ocean plays a part in the water cycle. In this earth science lesson, students locate a puddle outside and mark it with chalk. Students observe the changes in the water during the next two days.

Fourth graders study the water cycle and clouds. In this water cycle and cloud lesson, 4th graders determine the definition of condensation and watch a demonstration in which the teacher makes a cloud in a bottle. They discuss the water...

Students complete a WebQuest. In this water cycle lesson, students investigate the cycle through a WebQuest activity. Students research the water cycle through Internet resources and create a documentary video of their process.

Students identify the different types of water and explain in what proportions they exist on Earth. They identify and correctly label the parts of the water cycle and how these parts interact with each other. Students identify the...

Learners explore clouds.  In this weather lesson, students identify the steps in the water cycle, define condensation and evaporation, and relate this information to cloud formation.  Learners perform a cloud experiment,...

Students are able to explain how the water cycle recycles the earth's water supply. They are able to make use of the knowledge of land forms learned in social studies. Students are able to form a hypothesis on how/why the water cycle...

Students continue their examination of the existence of life on Earth. In groups, they determine the role of the water cycle and other biogeochemical cycles play in keeping balance on Earth. They participate in experiments to discover...

Sixth graders review how and which plants operate in terrariums. In groups, they follow instructions to make their own terrarium and place different types of plants in it. To end the lesson, they review the steps in the water cycle and...

Young scholars create their own water cycle in a terrarium. In this water cycle lesson, students research the water cycle and complete a worksheet using the Internet. They create a water cycle of their own in a jar with stones, sand,...

Students examine the water cycle and the factors that interact with watersheds.  In this watersheds lesson students describe the purification process, trace the flow of infiltrate water through aquifers, and research the Internet to...

Third graders draw the rain cycle. In this rain cycle lesson the students listen to the story The Legend of the Bluebonnet by Tommie DePola. As they listen to the story they sketch what is happening. The students write a sentence for...

As part of a unit, this lesson familiarizes youngsters with components of a rain garden. They speculate about the role of an assigned component in contributing to a rain garden, and ultimately, in the health of the local watershed. Each...

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...

First graders identify the different stages in the hydrologic cycle. To study earth science, they investigate how sunlight affects the earth's temperature. They also discuss how the sun's energy is transformed.

Students examine the rock cycle by watching videos and then use creative storytelling techniques to tell the story of a rock as it undergoes geologic changes.
