One of the most alarming impacts of projected climate change is a significant rise in sea level. Sea level has varied by hundreds of meters over geologic time, yet these changes have generally been slow paced, allowing ecosystems to adjust to changing land surface and marine habitats. Since the Industrial Revolution, anthropogenic emissions have…

The United Nations has proclaimed 2011 as the International Year of Chemistry and, as part of that designation, has invited teachers worldwide to participate with their students in the Global Water Experiment (IYC 2010). Students have the opportunity to take part in four different water-related investigations to assess water quality and then share…

Water is one of our most precious resources. However, for many in the United States, having fresh, safe drinking water is taken for granted, and due to this perceived lack of relevance, students may not fully appreciate the luxury of having safe running water--in the home. One approach to resolving water-quality issues in the United States may…

Take advantage of teen internet savvy and redirect students' online travels toward exploration of our environment through streaming real-time data (RTD). Studies have shown that using RTD adds relevancy to students' learning experiences and engages them in scientific investigations. (Contains 14 online resources and 5 figures.)

Case studies are an excellent method for engaging middle school students in the current work of scientists. Students learn to think like scientists as they decide how to investigate the dilemma presented in the case study. This article describes one such case study, the Fish Kill Mystery, which takes place at a popular vacation spot--the beaches…

Water is an essential resource for all living things. How we live on our watershed can impact water quantity and quality. It is important to recognize how humans alter watershed dynamics, but students often find it challenging to visualize watershed processes and understand how decisions that they make as individuals and together as a community…

The Oregon 4-H Wildlife Stewards program has been training teachers and volunteers to convert school grounds to education sites by constructing schoolyard wildlife habitats since 1997. The publication "What Can We Learn at the Pond? 4-H Wildlife Stewards Master Leader Guide" (Bourdeau 2004a) was written to support the program's focus on developing…

Biobottles are miniature ecosystems made from 2-liter plastic soda bottles. They allow students to explore how organisms in an ecosystem are connected to each other, examine how biotic and abiotic factors influence plant and animal growth and development, and discover how important biodiversity is to an ecosystem. This activity was inspired by an…

Presents a three-day mini unit on purification of drinking water that uses the learning cycle approach. Demonstrates the typical technology that water companies use to provide high-quality drinking water. (JRH)

The American Geological Institute is helping teachers and geoscientists to emphasize the importance of inquiry and active investigation of the world around by selecting "Eyes on Planet Earth: Monitoring Our Changing World" as the theme of this year's Earth Science Week. The activity on the back of this month's poster insert, "Monitoring the…

Describes an integrated student-designed investigation in which students explore different aspects of the Chagrin River including the river ecosystem, velocity and average depth, river flooding, water quality, and economic and political factors. (JRH)

Describes the watershed management approach for preserving water resources. Considers pollution sources ranging from industrial discharge to agricultural leachate and runoff and evaluates its impact on the total watershed environment. (JRH)

Investigating local watersheds presents middle school students with authentic opportunities to engage in inquiry and address questions about their immediate environment. Investigation activities promote learning in an investigations interdisciplinary context as students explore relationships among chemical, biological, physical, geological, and…

Teachers can use inquiry to make sure that student learning is hands-on and minds-on. There are many levels of inquiry and teachers can even include some of their favorite cookbook labs after modifying them. Inquiry does not always mean lots of time, money, materials, and mess. One of the most important things that inquiry does require of…
