INTERMOLECULAR forces, DATA analysis, INSTRUCTIONAL systems design, CHEMISTRY, PHYSICAL sciences, and EDUCATION
Connecting abstract science concepts to real-world phenomena and experiences proves difficult for many learners, and intermolecular forces are counted among the more challenging topics because of their abstract nature. Mastery of intermolecular forces is crucial to chemistry, physical science, general biology, and molecular biology, as they influence physical properties of substances, protein folding mechanisms, and the DNA double helix. The intermolecular forces activity presented in this article is designed to foster concept-building through students' use of concrete, manipulative objects, and it was developed to be pedagogically sound. Data analysis via pre- and posttesting and subsequent exam questions indicated that students who had the opportunity to participate in the activity were better able to identify and apply intermolecular forces both immediately after completion of the activity and also at the end of the semester. This activity has broad applicability in its usefulness to AP chemistry or biology, general chemistry, organic chemistry, biochemistry, physical chemistry, general biology, and molecular biology, as intermolecular forces are relevant to all these content areas. In addition, the intermolecular forces activity is editable so educators from a variety of courses or educational levels could modify it for use to meet their particular instructional goals. [ABSTRACT FROM AUTHOR]
SOIL chemistry, WATER chemistry, SPATIAL variation, and WATERSHEDS
The article presents the study which examines the spatial and temporal variability in surface water chemistry, organic soil chemistry and hydrologic indicators at three poor-fen complexes in two boreal catchments in Northern Alberta. The examination is intended to offer insights into the dominant controls on surface water chemistry. The relation between exchangeable base saturation and potential of hydrogen (pH) of organic soils with surface water chemistry at two of the fen complexes is cited.

CHEMISTRY, FOOD science, FOOD packaging, COOKING, MATHEMATICS, ENGLISH people, INFORMATION services, TECHNICAL writing, and STUDENTS
The article reports on the connection of Food Science Class with the basic principles in Chemistry. It covered the basic principles of chemistry, organic chemistry, biochemistry and microbiology. Other topics involved in it are the study of food production, processing and packaging and its principles were linked to real-life applications with food. It also dealt on Math and English skills and integrated the major fields of scientific study with nutrition, technology, history and food preparation. Its laboratories involved data collection, development of tables and technical writing and are designed to help students apply Math and Algebra 1 skills through calculation of mass percentages, averages and density and showed students on which procedure worked best and why.
