The main goals of these activities are to help students learn how a convex lens can serve as a magnifying lens and how light travels and creates images. These explorations will introduce middle school students to different types of lenses and how they work. Students will observe and describe how lenses bend light that passes through them and how…

In this extended earth science activity, students create a hands-on model of a volcano to achieve an understanding of volcanic structure, lava flows, formation of lava layers, and the scientific work of archaeologists and geoscientists. During this simulation activity, students have opportunities to learn science as inquiry and the nature of…

Virtually every student knows someone who has battled cancer. It is a topic that is of great interest to many students because of their personal connection to the subject. Mitosis is an important topic in a middle school unit on cells and cell processes (National Science Standards, Grades 5?8: Life Sciences: Content Standard C). Studying cancer…

This article is an outline of what the author did in his classroom to incorporate the help of two volunteer engineers to create a powerful learning unit and cumulative review for his eighth-grade physical science students. This unit reviews what students have learned during the school year regarding force, motion, Newton's laws, gas laws, and…

An activity called "Project Physics, a Classroom Without Walls" was started during the spring of 2003 at the amusement park in Mirabilandia (Italy). Many thousands of students from Italian middle and high schools are today participating in the initiative. Under the guidance of trained tutors, they perform physics experiments on some of…

Learning in educational settings most often emphasizes declarative and procedural knowledge. Studies of expertise, however, point to other, equally important components of learning, especially improvements produced by experience in the extraction of information: "Perceptual learning." Here we describe research that combines principles of…

Chemistry should be fun and exciting, but much preparation and skill are needed by the teacher and students in working with chemicals. Unfortunately, accidents do happen and things can blow up, but these incidents can help be prevented by knowing and following proper safety procedures. Knowing which chemicals are appropriate for the middle level…

An infrared (IR) thermometer lab offers the opportunity to give science students a chance to measure surface temperatures, utilizing off-the-shelf technology. Potential areas of study include astronomy (exoplanets), electromagnetic spectrum, chemistry, evaporation rates, anatomy, crystal formation, and water or liquids. This article presents one…

Wondering how to make the study of the immune system and infectious agents more relevant to your students' lives? The online adventure series, Medical Mysteries, can provide the context and motivation. The series combines the drama of television's "CSI" episodes with science to address several of the National Science Education Content Standards.…

In this paper, the authors describe their development of an introductory laboratory course in microbiology that is geared towards students in grades 8-10. The course was developed as part of the Mentoring for Science Program at Harvard Medical School, an outreach program created by the Minority Faculty Development Program, directed towards…

An experiment is reported that investigated the development of students' understanding of the numerical value of fractions. A total of 200 students ranging in age from 10 to 16 years were tested using a questionnaire that required them to decide on the smallest/biggest fraction, to order a set of given fractions and to justify their responses.…

The recent promotion of inquiry-based learning techniques (Uno, 1990) is well suited to the use of animals in the classroom. Working with living organisms directly engages students and stimulates them to actively participate in the learning process. Students develop a greater appreciation for living things, the natural world, and their impact on…

This paper presents the development of a 3-D virtual environment in Second Life for the delivery of standards-based science content for middle school students in the rural Appalachian region of Southeast Ohio. A mixed method approach in which quantitative results of improved student learning and qualitative observations of implementation within…

"The Dirty Water Challenge" is a fun activity that teaches children about their environment in an engaging and practical way. Inquiry is embedded within the practical--students have to design, plan, and then build their own design of water filter. Students are exposed to important concepts from a variety of scientific disciplines, including how…

A summer outreach program, which was implemented for the first time in the summer of 2004, that provided middle school girls with an opportunity to conduct college-level analytical chemistry experiments under the guidance of female graduate students is explained. The program proved beneficial to participants at each level.
