In this article, the author describes an activity using physical models -- each a clear plastic box enclosing a miniature coastal town, complete with real water in the "ocean." This activity shows students a natural cause-and-effect relationship that is scientifically simple, yet even many adults don't grasp the worldwide implications:…

STEM is a commonly used acronym in today's education world. Parents hear the term and hope their child's school will be embracing it, teachers plan units encompassing it, even those outside the education realm have heard it and think it is important. But, do students actually understand the four disciplines and can they clearly express what they…

This article describes how one preschool teacher turned a luau celebrating moving on to elementary school as a springboard for a lesson on pollution. Over the course of one hour, this teacher introduced and provided a whole group lesson on pollution, and the responsibilities people share to protect the environment.

This column contains exercises to challenge content knowledge. This month's issue discusses ways to remove CO[subscript 2] from the atmosphere.

Human-made pollution is a large and complex problem that has harmful effects on communities and ecosystems. Understanding these impacts is essential, but it can be daunting when many types of chemical pollution are difficult to conceptualize, especially for elementary school students. Something every student can understand, however, is trash.…

Makerspaces have become very popular in education because they "provide hands-on, creative ways to encourage students to design, experiment, build, and invent as they deeply engage in science, engineering, and tinkering" (Cooper 2013). Not only do makerspaces provide a safe learning environment for students to develop their 21st century…

Place-based education is a form of teaching and learning that allows the teacher to understand the cultural norms of the learners and ensure that cultural norms and local content are reproduced within the classroom so that learning is meaningful, student-centered, and applicable. The traditional definition of place-based education focused on…

Acid rain is the collective term for any type of acidified precipitation: rain, snow, sleet, and hail, as well as the presence of acidifying gases, particles, cloud water, and fog in the atmosphere. The increased acidity, primarily from sulfuric and nitric acids, is generated as a by-product of the combustion of fossil fuels such as coal and oil.…

The term acid rain describes rain, snow, or fog that is more acidic than normal precipitation. To understand what acid rain is, it is first necessary to know what an acid is. Acids can be defined as substances that produce hydrogen ions (H+), when dissolved in water. Scientists indicate how acidic a substance is by a set of numbers called the pH…

Some of the background factors and deleterious effects of oil spills are discussed. A classroom activity which demonstrates an oil spill, how the oil affects feathers, and one clean-up method is presented. A list of recent oil spills and three additional resources are included. (CW)

No two oil spills are the same. Logistically, oil spills are a nightmare because they are unanticipated and uncontrolled events. Oil spills present a threat to wildlife and coastal resources, concerning everyone from local residents to state environmental agencies and the federal government. Thousands of people may be involved in a significant…

Investigations with Wisconsin Fast Plants can make the subject matter come alive...or dead, depending on the experimental treatment. This became apparent when a university-based teacher educator and a fifth-grade teacher collaborated on a professional development experience aimed at increasing understanding of how science inquiry could be used…
