Students can be taught to solve numerical problems by using the unit system. Conversion operations from one unit to another can be easy by this method. Several examples are presented. (PS)

Describes a scavenger hunt activity that has been used successfully with middle school students in an earth science course. This activity includes items that call for library research rather than the collection of objects, emphasize real-world connections, are skill-oriented, ask for originality and creativity, and are just for fun. (JRH)

Describes how to construct a simple DC electric motor. (MKR)

A game used for test review based on the television game show "Jeopardy" is described. Sample categories, rules, models for category cards, answer pockets, and answer cards are included. (KR)

Several suggestions are provided for making life-science programs effective in junior high schools. Teacher's job can be made lighter if advanced planning and execution are done wisely. Problems ranging from shortage of space to final grading are discussed. Workable solutions are suggested for each situation. (PS)

Describes an activity for grade 7-9 students previously introduced to topographic maps and profile lines. Two profiles of equal scale are used to help students appreciate the tremendous size of mid-ocean rift valleys. Procedures and examples of completed profiles are provided. (JN)

Describes activities to introduce middle school students to the metric system. Involves converting common cookbook recipes from English to metric measure and then having students reconvert the recipes and prepare them as an assignment. (JRH)

Instead of teaching scientific laws and principles in a classroom situation, author involved junior high students in reconstructing an automobile from ole parts in junkyard. The community showed interest by providing old, unusable materials needed for the project. (PS)

A physical science activity that helps students understand biological adaptation is described. The ease with which something can move through its surroundings depends on its shape. This idea is presented using different shapes of paper and bars of soap. These shapes are then compared with the shapes of fish. (KR)

Activities in which students can learn to determine the history of a tree from the growth pattern recorded in the rings of a cross-section of a tree are described. Activities include background information, objectives, a list of needed materials per group, and procedures. Cross-sections of four different tree types are included if real tree…

This form is used as a measurement of student's on-task activities. It indicates the incorporation of science skills into each individual student's repertoire and provides a record of the activity to assure parents, board members, and teachers that learning is taking place in the classroom. (PR)

Explains the terms resonance and amplitude, the relationship between them, and the effects of resonance in our daily lives. Introduces pendulum activities that explain how resonance works. (YDS)

Provides directions for the construction of two different kites in the junior high school science classroom. (JR)
