Students consider that ammonium nitrate is used as a fertilizer and an explosive. They study the chemistry of ammonium nitrate and consider the advantages and disadvantages of this compound. The dual nature of Ammonium Nitrate was...

Students examine the effects of nitrates and phosphates on the dissolved oxygen levels in different water sources. For this series of 3 lessons, they consider the reasons for nitrate and phosphate level increases and their effects on...

Students study the quality of water by running chemical tests on the water. First, they measure pH, temperature, phospates, and nitrates in tap (drinking) water and an outdoor water sample. Then they post and evaluate the results of...

Students investigate the effects of pollution on marine ecosystems. They read and discuss an article, identify the effects of pollution on marine life, conduct research on local nutrient pollution, and conduct local water quality studies.

What does it mean to be a good steward? Middle school environmentalists learn to care for their state's waterways through research, a guest speaker, and poster activity. Groups must locate and learn more about a river basin and the human...

What's in your water? And, why is water quality so important? Enhance your class's level of water appreciation through a lesson plan that demonstrates the necessity of water quality. Environmental enthusiasts explore the EPA's Clean...

Learners discover correlations in food preferences of invertebrates, and assess stream health through use of kicknets, invertebrate keys, CBL systems and probes.

Learners take a virtual trip to a Catfish Aquaculture Pond and analyze soil bacteria to determine how many nitrogen cycle bacteria are present. They graph the number of colonies present and use data to determine ammonium levels in the soil.

Students identify patterns and relationships from data that is collected and solve variables.  For this investigative lesson students study ocean productivity, the nitrogen cycle and phytoplankton then answer questions.

Students experiment with local lake water to determine the health of the lake waters. They explore the human impact on the lake water, hypothesize and share inferences in a scientific report.

Students are introduced to biomolecules and their roles in livin systems. They are introduced to the "Elements of Life." Students write down and define the "Elements of Life." They are asked why they think those elements are essential...

Students explore human discovery by reading historical stories in class. In this inventors lesson, students define the terms scientist, invention, inventor and discovery before discussing the many differences between them. Students read...

Learners construct flow diagrams of the carbon and nitrogen cycle processes. They identify sequences in each cycle that are affected by human impact and present their research to the class.

Fourth graders study the Texas City Disaster, the largest industrial accident in United States history. They examine the explosions of the SS Grandcamp and the SS High Flyer and their effect on the oil refining center of Texas City and...

Young scholars trace a molecule of water through the water cycle including each of its three loops. They describe why evapotranspiration demands the largest portion of total precipitation falling on a forested watershed.

Students begin the lesson plan by noting the many ways in which to use peanuts. In groups, they use the internet to research the work of George Washington Carver. They discover the allergies and nutritional information of the peanut and...
