Discover the secrets contained in fossilized feces. Few topics in middle school classrooms capture students' enthusiasm and interest as do coprolites. These trace fossils offer classroom opportunities for integrated life and Earth sciences study, a stranger-than-fiction history of science, and an opportunity to solve mysteries. (Contains 8…

Middle school students often struggle when writing testable problems, planning valid and reliable procedures, and drawing meaningful evidence-based conclusions. To address this issue, the author created a student-centered lab handout to facilitate the inquiry process for students. This handout has reduced students' frustration and helped them…

In this inquiry-based project, student-generated questions became the basis for student-directed individual and group projects that provided practice with problem solving, critical thinking, and research skills while digging deeper into the Earth science curriculum. The author used her students' high-level questions to provide relevance,…

The "What's the "matter" With XOD" activity addresses students' misconceptions and refines their ideas about phases of matter. This activity introduces the characteristics for solids, liquids, and gases, and begins a discussion about physical and chemical changes and how matter can cycle through different phases. Depending on class size and…

As educators we must ask ourselves if we are meeting the needs of today's students. The science world is adapting to our ever-changing society; are the methodology and philosophy of our educational system keeping up? In this article, you'll learn why web logs (also called blogs) are an important Web 2.0 tool in your science classroom and how they…

Design briefs are plausible situations in which students are asked to solve problems given limited materials, a specific time frame, and a number of rules and limitations. It is the author's contention that the design brief, an established format in technology education, can serve as a unique approach to extend and assess everyday science…

Problem-based learning experiences that extend at least two weeks provide an opportunity for students to investigate a real-world problem while learning science content and skills in an exciting way. In this article, students are challenged by the president of the United States to serve as employees of the Federal Emergency Management Agency to…

Explains modeling as a teaching approach and presents two examples of modeling, one example of poor modeling and one example of good modeling. (YDS)

Genetics is often a fascinating but difficult subject for middle level students. They can see the results of genes in every organism, but trying to visualize what happens at the level of genes is challenging for concrete thinkers. The author discusses an approach that helps students understand how genotypes can translate into phenotypes, then…

Presents an activity that uses basketball shoes to introduce the concept of friction. Discusses setting up, friction fundamentals, and fun friction facts. (JRH)

From the start of the year, the author's goal is to teach his students to be metacognitive thinkers. This means that they will think about what they are doing during each step of the inquiry process. The author uses a variety of methods to enculturate students into using the thinking processes and developing the dispositions necessary for them to…

Discusses strategies for overcoming common student misconceptions. Strategies include using pretests followed by teaching techniques planned to contrast new information with students' previous ideas; using pretests followed by time for students to question ideas and test their knowledge; and giving students a real-world task that can only be…

Presents an activity using logic mystery stories that students solve by asking yes-or-no questions. Helps students discover the reasoning behind good questioning and provides for practice with instant feedback from the teacher. Includes sample stories. (MKR)

Describes an activity designed to teach students geology vocabulary while challenging them to solve the case of the missing marble. Can be adapted to teach vocabulary for different topics. (JRH)

Describes a science competition challenge that has students solve several hands-on physical science problems, thus reinforcing both problem-solving skills and science knowledge. (PR)
