Science starts at home. Parents play a crucial role in determining how much science their children learn. This paper presents a list of tips that parents can use to help their children learn science. They are: (1) Focus on your child's interests; (2) Talk with your child about what you are doing-- make it a two-way conversation; (3) Girls are just…

Uses Newton's laws of motion to describe the theory behind the observation that when bread falls off a table it always lands butter-side down. (JRH)

Discusses descriptions of the way in which an optical system controls the quantity of light that reaches a point on the image plane, a basic feature of optical imaging systems such as cameras, telescopes, and microscopes. (JRH)

Asks the relationship between mass and skidding distance. Provides a problem with illustrations and an answer. (YP)

Presents an alternative approach to teaching Systematic Transition Metal Chemistry with the transition metal chemistry skeleton features of interest. The "skeleton" is intended as a guide to predicting the chemistry of a selected compound. (Author/SA)

Described is the subject of biological scaling for physics teachers including examples and in-depth reading. Topics are elements of scaling, terminal velocities, Lilliputian and Brobdingnagian, brain evolution, dolphin echolocation, surface tension, gravity change, food and oxygen, and seeing. Ten references on physics and size, and ten questions…

Why do people, college-bound or even in college, stay away in droves from courses in science, especially physics? Why do people know so little about the significance of Einstein's contributions which require dramatic changes in how we understand ourselves, our world, and the entire universe? Why have educational reforms failed? In this book, two…

Various phenomena in chemistry and biology can be understood through Gibbs energy utilization. Some common phenomena in chemistry are explained including neutralization, hydrolysis, oxidation and reaction, simultaneous dissociation equilibrium of two weak acids, and common ion effect on solubility. (Author/SA)

An explanation of strong base effect demonstrates that deprotonation of a reactant shifts an equilibrium toward reactants in the same way that a deprotonation of a product shifts it towards products. (Author/SA)

This booklet is designed to supplement the study of introductory chemistry. It deals particularly with the mole concept but also includes ideas for analyzing the kinds of statements that appear in all science textbooks and scientific writing. The material in the booklet should be studied after the completion of an introductory textbook study of…

Discusses the average speed differences between hydrogen and oxygen molecules contained in a jar. (YP)

This booklet presents the language used in dealing with water. The booklet is intended to provide decision-makers with an adequate base of information to analyze water sources for consumption, recreation, and industry. The first section defines water and its properties, geologic locations, domestic and industrial uses, and patterns of change. The…

This teacher's handbook provides information about the philosophy, rationale, and teaching strategies of the Science Curriculum Improvement Study (SCIS) program, as well as information about the SCIS physical and life science sequences to provide teachers with an understanding of the program's overall content and structure. Much of the material in…

The fourth of four levels in a K-12 science curriculum is outlined. In Level 4 (grades 9-12), science areas include earth science, biology, chemistry, and physics. Six major themes provide the basis for study in all levels (K-12). These are: Change, Continuity, Diversity, Interaction, Limitation, and Organization. In Level 4, all six themes are…

Answers a student's question about the emission of a positron from a nucleus. Discusses the problem from the aspects of the uncertainty principle, beta decay, the Fermi Theory, and modern physics. (YP)
