The tree house detectives go galactic with their latest project by traveling to Mars and also seeing how the Moon affects the Earth. They visit the largest radio telescope in the world and help look for intelligent life in the universe. The tree house detectives prepare for an out-of-this-world vacation as they explore the future of space travel.…

Describes a learning activity when students construct a model of a buried valley by using computer assistance. Explanation of the problem includes mathematical models and illustrations. (MA)

This teacher's guide, with accompanying videotape, presents an episode of the NASA SCI Files. In this episode, one of the tree house detectives has had an accident and cannot get into the tree house. Using problem-based learning, the rest of the gang investigates the world of simple machines and physical science and "pull" together to…

Describes a learning module designed to help students use the factor labeling method in problem solving. (ZWH)

This curriculum unit describes geothermal energy in the context of the world's energy needs. It addresses renewable and nonrenewable energy sources with an in-depth study of geothermal energy--its geology, its history, and its many uses. Included are integrated activities involving science, as well as math, social studies, and language arts.…

The relationship between specific gravity, salinity, and density in brine solutions is investigated. Students construct hydrometers to reinforce concepts learned in oceanography. Background information, salt requirements for the unknowns, directions, and reproducible worksheets are included. (KR)

Presented is the best understanding of the flaw discovered in the optics of the Hubble Space Telescope and the possible solutions to the problems. The spherical aberration in the telescope's mirror and its effect on the quality of the telescope's imaging ability is discussed. (CW)

Describes a lesson plan for use in physical geography, earth science, and social studies classes. Suggests that students will find the problem solving approach interesting and will use knowledge of earth-sun relationships, absolute location, and place. Includes objectives, two days of learning activities, evaluations, resources, and an activity…

Describes an extended problem-solving activity utilizing drift-bottles that encourages students to deduce probable and great-circle drift-bottle routes, to use logic based on unit calculations, and to estimate the distance traveled and the minimum velocity of these drift-bottles. Includes materials needed, learning objectives, procedures,…

Presented are 27 science activities for secondary school science instruction. Topic areas include microbiology, botany, biochemistry, genetics, safety, earthquakes, problem solving, electricity, heat, solutions, mechanics, quantum mechanics, flame tests, and molecular structure. (CW)

Describes activities in which students learn that it takes teamwork, problem solving, and personal commitment to save the environment. (PR)

Describes a computer program written in Microsoft BASIC for use on personal computers to calculate travel times of refracted waves in layered structures with arbitrary dipping interfaces. Exercises for student use are given to illustrate some of the basic properties of reversed refraction travel time graphs. (TW)

This curriculum guide lists science topics and concepts, learning outcomes, and sample learning objectives (in three columns), separately for grades 1-3 and for grades 4-6. Topics/concepts, in the first column, describe the major parts of the subject under consideration. They define broadly the content to be included in the study of each subject…
