This investigation was part of a multi-lesson unit that gave students direct experience using increasingly sophisticated tools to make more detailed observations and measurements of light. Through these lessons, students experienced a key aspect of the nature of science (McComas 2004), namely how scientists constantly refine and modify theories as…

To introduce students to rocks and their characteristics, teacher can begin rock units with the activities described in this article. Students need the ability to make simple observations using their senses and simple tools.

A rock investigation set up as a problem-based learning mini-unit for the author's seventh grade integrated science students. To start this unit, she explains to students that NASA has sent us a container of rocks that they would like to have identified. It is up to the students to assume the role of geologists and come up with some way to…

Collecting weather data is a traditional part of a meteorology unit at the middle level. However, making connections between the data and weather conditions can be a challenge. One way to make these connections clearer is to enter the data into a database. This allows students to quickly compare different fields of data and recognize which…

This article describes an interdisciplinary unit of study on the inquiry process and experimental design that seamlessly integrates math, science, and reading using a rubber band cannon. This unit was conducted over an eight-day period in two sixth-grade classes (one math and one science with each class consisting of approximately 27 students and…

Describes an activity based on shrinkable thermoplastics in which students explore the percentage of shrinkage of a plastic ruler when it is heated. Includes science content knowledge behind the shrink, national science education standards related to this activity, and a complete guide. (KHR)

Reading Harry Potter aloud to the class one autumn sparked the students imaginations and also the authors'. As a result, that semester the author designed and taught a thematic unit based on Harry Potter. The students were able to identify with the 11-year old wizard and his adventures in a strange new world. In mathematics, language arts, and…

Describes a series of activities exploring Leonardo da Vinci's tree theory that are designed to strengthen 8th grade students' data collection and problem solving skills in physical science classes. (KHR)

In a perfect world, what would a good classroom strategy look like? It would have to work for any teacher at any grade level in any discipline; be backed by current research in learning theory; be elegant and simple to facilitate but differentiate for each student; be cost effective but use a diverse selection of materials; and be active and…

Demonstrating wave processes quantitatively in the classroom using standard classroom tools (such as Slinkys and wave tanks) can be difficult. For example, waves often travel too fast for students to actually measure amplitude or wavelength. Also, when teaching propagating waves, reflections from the ends set up standing waves, which can confuse…

Provides strategies for adapting microscope activities for students with disabilities. The following factors are considered: (1) mainstreaming strategies; (2) laboratory techniques; (3) observing and classifying; (4) vocabulary and terminology; and (5) safety. (ZWH)

Describes a project where students build their own catapults and modify them to solve four problems. Suggests the unit be integrated with a social studies unit on the Middle Ages. (PR)

An eighth-grade science teacher shares her successes and strategies for designing and implementing an individualized scientific investigation approach for students with three major problems: (1) low reading ability, (2) high absenteeism, and (3) limited background in science. (ZWH)

Describes using the movie "Jurassic Park" as a foundation for a middle school interdisciplinary unit involving science, math, language arts, history, and geography. Suggested books and activities are presented. (PR)
