This unit is a different and fun way to engage students with an extremely important topic, climate change, which cuts across scientific and nonscientific disciplines. While climate change itself may not be listed in the curriculum of every science class, the authors contend that such a unit is appropriate for virtually any science curriculum.…

Having students design their own methods regarding data collection during a lab may help them formulate appropriate investigative procedures. The authors use a modified gallery walk to develop science skills. (Contains 3 figures.)

In the exciting, "out of this world" activity described here, students measure the Earth using meter sticks while measuring their shadows in two distant locations. To obtain the size of the Earth, students discover the connection between the measurements of the shadows and a model of the spherical Earth following the method developed by…

Proportionality should be a central focus of the middle-grades science and mathematics curricula and concepts such as density can be introduced and taught in both disciplines, highlighting for students the connections between science and mathematics. This month's column describes how teachers can utilize the "The Atlas of Science Literacy" and…

This article contains a foldout entitled Natural Gas and the Environment for use in helping students become more aware of the relationships that exist between humans and the environment. Suggestions for classroom integration of this subject into your curriculum are also provided. (ZWH)

Presents an activity on the electrostatic phenomenon known as induction. Reviews the principles illustrated by each of the activities described in this series. (DDR)

Presents a modification of a procedure for making and launching hot air balloons made out of garbage bags. Student instructions for balloon construction, launching instructions, and scale diagrams are included. (DDR)

Explains why performance tasks should be used for assessment in hands-on science programs. Lists guidelines to help teachers construct valid tasks for student or program evaluation. Illustrates the guidelines by discussing a chromatography task from the Second International Science Study test. (PR)

Teaching science in middle school is both rewarding and demanding. Creating an exciting learning environment with a rich science curriculum that engages all students is challenging enough. Monitoring the progress of as many as 150 individual students and knowing that they understand the science concepts we are teaching can be overwhelming. How can…

With such curriculum gaps, it is hardly surprising that middle school children's understanding of botany is limited and riddled with misconceptions. Knowing that plants supply the oxygen to sustain most life forms and provide the primary energy source of most food webs is a core idea of science. Investigating non-native species is one way to…

The brain is a truly fascinating structure! It controls the body and allows everyone to think, learn, speak, move, feel, remember, and experience emotions. Although the brain is a single organ, it is very complex and has several regions, each having a specific function. These functionally diverse regions work together to allow for coordination of…

Presents an activity that focuses on insects and the choices they make in response to sensory input. Involves students and teachers in inquiry-oriented investigations and presents details of preparation, a discussion of the teacher's role, and a materials list. (DDR)

Details the use of computer technology for classroom presentations to students. Includes tips on software, hardware, and monitoring student opinion. (DDR)

Presents a concept-map scheme that provides a consistent syntax and grading system for using concept maps as assessment tools. The grading scheme awards points for demonstrating hierarchies, relationships, branching, and cross links. Examples showing the use of the key are presented. (PR)

Suggests gardening to help middle school students improve their problem solving and mental abilities. Focuses on the benefits of having a school nutrition garden, and indicates that students can learn about the importance of a healthy diet and share their peers' cultural heritage by growing ethnic foods.
