This article outlines how to incorporate argumentation into a forensic science unit using a mock trial. Practical details of the mock trial include: (1) a method of scaffolding students' development of their argument for the trial, (2) a clearly outlined set of expectations for students during the planning and implementation of the mock…

This article presents an authentic writing opportunity to help ninth-grade students use the writing process in a science classroom to write and illustrate picture books for fourth-grade students to demonstrate and share their understanding of a biology unit on cells. By creating a picture book, students experience the writing process, understand…

This activity introduces the science of "forensic palynology": the use of microscopic pollen and spores (also called "palynomorphs") to solve criminal cases. Plants produce large amounts of pollen or spores during reproductive cycles. Because of their chemical resistance, small size, and morphology, pollen and spores can be…

Learning about microscopic things, such as cells, can often be mundane to students because they are not able to see or manipulate what they are learning about. Students often recall learning about cell division through memorization--thus they find it tedious and dull. Few opportunities exist that allow students to explore and manipulate cells or…

Pressure increases rapidly with depth in a water body. Ocean and Great Lakes scientists often use this physical feature of water as the basis of a fun pastime performed aboard research vessels around the world: the shrinking of polystyrene cups. Depending on the depth to which the cups are deployed, the results can be quite striking! Capitalizing…

Reaction time, the time between a stimulus and a person's reaction to it, is a concept familiar to most teenagers, particularly in the context of driving. We describe a simple inexpensive activity that utilizes students' creativity and invokes the scientific method in order to explore reaction time. The goal of the activity is to give students a…

Teachers often struggle with controversy when teaching biological evolution in American schools. Research indicates that curriculum with a nature of science (NOS) focus quells controversy (McComas 2004; Scharmann 2005; Staver 2003). This article presents a 5E NOS series that is a first step in a NOS curriculum that situates student understanding…

The Bee Hunt! project and curriculum are designed with cultural and environmental sensitivity in mind. In this project, K-12 students develop their awareness and understanding of science and investigate North American pollinator declines. Bees, butterflies, and other pollinators are integrally connected to the pollination of the world's crops for…

This lab activity uses inquiry to help students define heat. It is generic in that it can be used to introduce a plethora of science content across middle and high school grade levels and across science disciplines that include biology, Earth and space science, and physical science. Even though heat is a universal science phenomenon that is…

This article discusses how sixth through twelfth grade science teachers can engage their students in the design and implementation of sustainable energy projects as part of a unit of study on energy. The project challenges students to engage in an energy project that gives them the opportunity to make a difference in their local community and the…

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…

For curriculum content-related reasons, inquiry activities can be difficult in classrooms unless the activities are approached in a manner that makes variations among student group findings understandable in the context of the study. Studies of individual animals and plant reactions to stimuli, such as insect exploratory behavior, allow the…

The authors illustrate an effective lesson-planning technique known as unpacking for the broad topic of water. Interconnections among science disciplines are shown for numerous possible subtopics. Two lesson sets are included, the first dealing with properties of water and the second dealing with water as a resource. (Contains 1 table and 4…

Even though photosynthesis is an obligatory part of the science curriculum, research has shown that students often have a poor understanding of it. The authors advocate that classroom coverage of the topic of photosynthesis should include not only its biochemical properties but also the role of photosynthesis or photosynthetic organisms in matter…
