Provides outdoor homework assignments that are hands-on learning activities covering all academic areas and requiring very little material or expertise. Activities can be adapted for grades 1-6 and should be evaluated on the basis of effort, creativity, presentation, and the amount of information gathered. Contains 16 references. (DDR)

Describes a curriculum designed around a series of investigative, macroscopic problems that enable students to learn the big picture of modern biology for themselves. Presents a hands-on investigative activity that gives students an accurate, easily grasped analogy for DNA expression. (JRH)

Presents a strategy for teaching students about electricity. Uses concrete activities to enlighten students about electron flow, resistance across a wire, and uses of electrical power. (JRH)

Provides activities that explore the concept of solubility using correction fluid. Topics include oil versus water solubility and whole milk versus fat-free milk. (DDR)

Describes some inquiry-based labs in which students identify starch in popped popcorn, then determine whether starch is present in the kernels prior to them being cooked. Students distinguish monocot and dicot stems as well as determining whether boiling kills tissues in seeds that have been soaked in water. (DDR)

This paper reviews science education research conducted with students having behavioral disorders. Both textbook-based approaches and activities-based approaches were found. Guidelines for teaching science to this population are provided, such as making participation in desirable activities contingent upon appropriate behavior and providing…

Presents an activity that uses the study of earthquakes to provide a rich educational experience to reinforce and expand students' knowledge of the structure of the Earth, provide an application of physics concepts such as force and energy, and present these topics integrated with a unit on mathematics. (JRH)

Demonstrates the need for a three-dimensional model as an aid for teaching students why eclipses do not occur every two weeks, as falsely indicated by two-dimensional models such as books, chalkboards, and computer screens. Describes procedure to construct the model. Indicates question related to seasons likely to arise from such a model and…

Describes experiments to culture cells in a laboratory that provide students with hands-on experience in manipulating cells and a chance to observe cell growth characteristics first hand. Exposes students to sterile technique, cell culture, cell growth concepts, and eukaryotic cell structure. (JRH)

Presents the plans for y-suspension, coupled, and double pendula and explains in detail why they move as they do. The mathematics that describes the motion is examined. (DDR)

Summarizes research into how children perceive three-dimensional objects. Focuses on the difficulty that students have in appreciating how the orientation of the semicircular canals affects balance and space perception. (DDR)

Describes a procedure developed by students that measures the mass concentration of particles in a polluted urban atmosphere. Uses a portable fan and filters of various materials. Compares students' data with official data. (DDR)

Proposes that it is critical for children to understand and appreciate plants, and that gardening can be integrated into the regular school curriculum. Gives examples of "pizza garden" and flower garden projects related to math, science, language arts, creative arts, nutrition and health, physical education, Earth stewardship, music, social…

Presents Living in Water, an aquatic science curriculum for grades five through seven that includes 50 activities divided into six sections. Focuses on the nature of content of the related workshops. (DDR)

Presents an overview of a museum teacher-in-residence program in which support is given for the development of curriculum materials relating to hands-on science instruction. (DDR)
