Students identify and describe the stages in the water cycle. Using plants, they determine if they play a role in the cycle and measure the water the plants give off. They complete an experiment to determine if deciduous or coniferous...

First graders investigate the different stages of the water cycle. They conduct Internet research and complete a water cycle WebQuest. Students identify what happens at each stage of the water cycle, and write about each stage in their...

Students complete a water cycle project. In this Earth science lesson, students use recycled objects from around their homes to illustrate the water cycle. Students illustrate evaporation, condensation, precipitation, saturation, ground...

Middle schoolers use common materials to construct a working model of the water cycle. They then observe and explain evaporation, condensation, precipitation and percolation as aspects of a continuing cycle. Students also complete...

The majority of this presentation is a collection of diagrams and graphs that back your lecture on biogeochemical cycles. The last few slides define ecosystems and the Gaia hypothesis. You may find these slides valuable, but will...

Scientists listen to the story of Wadja Egnankou who works to save African mangrove forests. They experiment with refraction and the introduction of particulate matter to water. They conclude with creative writing about the need for a...

Students analyze water samples to see the contaminants and then use the Internet to find the sources of the contamination.  In this investigative water lesson plan students analyze water and work together to solve the mystery of...

Students use stream trays covered in different types of rocks or soil to investigate infiltrates and runoff. In this water pollution instructional activity, students work in groups with stream trays that have different substrates. They...

Students use NASA photographs and hands-on activities to compare the amounts of land and water on our planet. They discover that the world has five oceans and that they cover seventy percent of Earth's surface. Students learn how this...

Bubble, bubble, boil and trouble! What causes common substances like baking soda and vinegar to react the way they do? Welcome your junior chemists to the wonders of acid-base chemistry using a comprehensive and fun...

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...

Provide your class with the opportunity to view our carbon cycle close up. Young scientists research the cycle of oxygen as it completes the tasks of photosynthesis and respiration. They explore the importance of carbon in an ecosystem...

Students recognize that all of the water on earth cannot be used for drinking and that the percentage of ground and surface water is a small percentage.  In this water lesson students identify ways to conserve water. 

As an example of nature's water filtering system, young ecologists conduct an experiment in the lab. They construct a funnel out of a plastic bottle, fill it with specified layers of materials that simulate layers of soil, then run muddy...

Students compare quantities of water. In this water lesson students examine the hydrologic cycle looking for the amount of fresh water that is available. Students use information from charts and diagrams.

Students create a water filter according to given criteria. I this chemistry lesson, students evaluate the importance of water in their lives. They develop a book or brochure on the water treatment process.

Pupils observe and discuss what happens when water turns to ice and when ice turns into water. In this freezing and melting lesson plan, students observe ice and water and complete hands on activities that change their properties.

Knowing about the hydrologic cycle is the first step to understanding the carbon cycle. Upper graders discuss the earth's water content, polar ice caps, and the concept of the ecological cycle as it applies to carbon, nitrogen, and other...

Students analyze the impact of climate variability and change utilizing a broad span of topics over a wide range of grade levels. This three lesson plan unit is easily adapted for the various instructional levels listed.

Begin a full lesson on climate change by demonstrating how carbon dioxide gas contributes to increased temperatures. Be aware that pressure inside the antacid-containing bottle in Activity 2 may cause the lid to fly off; keep viewers at...

Crawl into the world of the darkling beetle with this scientific investigation. Watch as the insects move through the larval, pupal, and adult stages of life, recording observations along the way. Discuss the necessities of life as young...

The blue king crab and the red king crab live in the same range but never in the same region. The third lesson in the series of five focuses on the blue king crab and the impact the changes in water temperature is having on its...

How do temperature changes affect ocean currents? Scholars explore convection currents by demonstrating the flow of water in a baking dish. They use ice, heat, and food coloring to see currents. Then, they draw conclusions about their...

Just as rocks move through the rock cycle, your giddy geologists will move descriptions around until they are all in the correct category. After cutting out several types of rock movement, learners determine whether the action is...
