The process of coral island formation is often difficult for middle school students to comprehend. Coral island formation is a dynamic process, and students should have the opportunity to experience this process in a synergistic context. The authors provide instructional guidelines for constructing a coral island. Students play an interactive role…

Flowering plants that live underwater in marine and estuarine habitats (seagrasses) are important because they support human food sources, such as crabs and fish, as well as endangered animals, such as turtles and manatees. Seagrasses are now known to be declining globally, largely as a result of increasing pressure from human populations living…

Dead zones--areas experiencing low levels of dissolved oxygen--are growing in shallow ocean waters around the world. Research has shown that dead zones form as a result of a specific type of pollution, called nutrient enrichment or eutrophication, and are found in almost every coastal zone where humans have large populations. Concepts related to…

In the activities presented in this article, students mimic real scientists while constructing predictions and scientific explanations about surface currents. The activities are inspired by and couched within true scientific inquiries regarding the ocean and the North American Great Lakes. Students engage in a classroom inquiry and use map-reading…

The implications of Earth's ocean being little explored may not be immediately evident to individuals who are not ocean literate. For this reason, initiatives to improve ocean literacy must articulate compelling reasons for ocean exploration. A lesson plan that addresses this issue has been developed as part of the education and outreach program…

This interdisciplinary activity promotes science, technology, and language arts and is well suited for upper elementary grade students. In the activity, students' research about a teacher-assigned weather phenomenon facilitates their study of the weather. When they have completed their research, students word process a paper summarizing their…

The authors introduced polar science in a fourth-grade classroom by means of 3 hands-on activities that addressed (1) the melting of glaciers and ice, (2) the differences between the North and the South Pole, and (3) the geography and landforms of Antarctica. An assessment 4 months after the original activity showed that students remembered the…

This activity targets students' misconceptions about embryonic and adult stem cells while also addressing an important grades 9-12 science content standard. The authors designed the activity to provide students an opportunity to explore differences between embryonic and adult stem cells prior to formal explanation. The overarching goal of this…

The purpose of this activity is to inform students about earthquakes and their movements and to give students an idea of how a seismograph works. Even though students may not experience an actual earthquake, the hands-on activity of creating a seismograph will give students an opportunity to visually explore concepts related to earthquakes.…

Learning about the water situation in other regions of the world and the devastating effects of floods on drinking water helps students study science while learning about global water quality. This article provides science activities focused on developing cultural awareness and understanding how local water resources are integrally linked to the…

Science education reached the headlines of the local newspaper: "Foundation donates $33M! American Chemical Society gets support for chemistry teaching." This windfall came from the Hach Scientific Foundation in Fort Collins, Colorado. The $33 million will go to continue three programs initiated by the Hach Scientific Foundation. One program will…

In this investigation, students make predictions and observations of a counterintuitive phenomenon. Given the scenario of a boat filled with a set of large rocks placed in a swimming pool, the students investigate what happens to both the water level in the pool and the level at which the boat floats when the rocks are taken out of the boat and…

Students in life science classes need an introduction to biomes, including an introduction to the concept, key biotic and abiotic features of biomes, and geographic locations of biomes. In this activity, students in seventh- and eighth-grade science classes used a directed exploratory Internet activity to learn about biomes. The author tested…

Although children often characterize animals by the animals' color or pattern, the children seldom understand the evolutionary and ecological factors that favor particular colors. In this article, we describe two activities that help students understand the distinct evolutionary strategies of warning coloration and camouflage. Because both of…

The authors present an activity to help high school students conceptualize the sociopolitical complexity of global warming through an exploration of varied perspectives on the issue. They argue that socioscientific issues such as global warming present important contexts for learning science and that the social and political dimensions of these…
