The activity described in this article poses a question, provides evidence needed to answer the question, and uses a cooperative learning structure within which students analyze the evidence and create their own questions. Students see how a single cause can interact with two natural systems--the water cycle and the bald eagle food chain--to…

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…

During Cave Week, more than 200 students explore a simulated cave environment and participate in cave-related activities. Active cavers from a local club bring in equipment and photos and speak about their caving experiences. As student groups explore the simulated cave, other groups participate in different activities where they can create bat…

You may not think of engineering and squirt guns in the same sentence. However, like many examples of engineering design, the squirt gun pump mechanism is uncomplicated, yet elegant, and very inexpensive to manufacture. The design is widely used because of its simplicity and low cost. With only a few moving parts, it is able to deliver a stream of…

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…

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…

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 methods and questions for discussion, activities, role plays, and assessment methods for helping students understand the importance of water conservation. (PR)

Describes a lesson plan on the movement of water in a water cycle. Presents a water cycle table that includes explanations. (YDS)

Watching Old Faithful transform from a smoldering mound to an explosive 50-meter high geyser is enough to generate awe in any observer. Behind this stunning, visual geologic display is a triad of heat, water, and plumbing that rarely unify on our planet. But geologists are not the only scientists drawn to geysers. Biologists have recently…

Presents an exciting way to acquaint students with current methods to clean up oil spills. Students also have the freedom to create new clean-up methods as they think through the problem and experiment to find effective solutions. (PR)

A local middle school requested that the Water Center of Advanced Materials for Purification of Water With Systems (WaterCAMPWS), a National Science Foundation Science and Technology Center, provide an introduction to pH for their seventh-grade water-based service learning class. After sorting through a multitude of information about pH, a…

Describes Project WET (Water Education for Teachers) for K-12 educators. (YDS)

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…

Describes a hands-on activity, Hitting the Mark, which is found in the "Healthy Water, Healthy People Water Quality Educators Guide" in terms of its objectives, materials, background, procedures, activities, and assessment. (KHR)
