Bumble bees are valuable pollinators of native and cultivated flora. Despite our knowledge of bumble bee nest site selection, most efforts to attract bumble bees to artificial domiciles have been met with limited success. Creating and evaluating artificial domiciles provides students an opportunity to investigate a real problem. In this lesson,…

The method for extracting and separating hydrophobic photosynthetic pigments proposed by Katayama "et al." ("Japanese Journal of Phycology," 42, 71-77, 1994) has been improved to introduce it to student laboratories at the senior high school level. Silica gel powder was used for removing water from fresh materials prior to…

Malathion is an organophosphorus insecticide, which is often sprayed to control mosquitoes. When applied to aquatic habitats, malathion can also influence the embryogenesis of non-target organisms such as frogs and fish. We modified the frog embryo teratogen assay in "Xenopus" (FETAX), a standard toxicological assay, into an investigative…

ChemSource is designed as a strategy to help preservice and inservice high school chemistry teachers promote student learning more effectively. Its major premise is that well-designed laboratory investigations are an important avenue for cultivating student interest, engagement, and meaningful learning in chemistry. The SourceBook component of…

One of the most valuable resources for obtaining exemplary instructional materials for the classroom is teachers. This booklet contains numerous laboratory activities compiled from submissions by recipients of the National Association of Biology Teachers' Outstanding Biology Teacher Award (1989-92). Topics are sorted into the following sections:…

This manual presents a design for teaching science principles and mathematics concepts through a sequence of activities concentrating on weather, solar food dryers, and nutrition. Part I focuses on the effect of solar energy on air and water, examining the concepts of evaporation, condensation, radiation, conduction, and convection. These concepts…

Designed to present interesting facts about science and to heighten the curiosity of primary age students, this book contains activities about the natural world and numerous black and white illustrations. The activities specifically focus on the human body and encourage a positive self-concept. The theme of the first section is air--the breath of…

Designed to address the major conceptual problems associated with respiration and photosynthesis, this module can be used with high school students or college nonscience majors including those in elementary education. It is one in a series developed by the project Overcoming Critical Barriers to Learning in Nonmajors' Science Courses. The…

Many educators assert that the acquisition of thinking skills by students is of primary importance to science education today. This study was designed to examine the effect of an instructional approach on achievement in science process skills when compared to a more conventional method of science instruction. The DIAL(SPS)2, a directed approach to…

The National Science Teachers Association (NSTA) has assembled this collection of reprints to assist teachers in organizing a science fair, working with students and establishing equitable judging procedures. The NSTA position statement on science fairs is included. The 24 reprints in this volume are geared toward elementary and middle school…

This guide was developed with the intention of helping teachers and school site administrators in California review the elementary science curriculum and compare it to an idealized model that is presented in the document. Part I of the guide provides a summary of a number of characteristics considered to be important to a strong elementary science…

This guide, the first in a series of three, provides the Spanish-speaking intermediate science student and teacher an opportunity to review selected science concepts and processes through activities which emphasize the applicability of scientific knowledge in the professional world. The three components in this guide deal with (1) ecology (what…

Project SOAR (Stress on Analytic Reasoning) is a pre-college summer program for natural, health, and mathematics science majors jointly developed and conducted by the Departments of Biology, Chemistry, Mathematics/Computer Science and Physics/Pre-Engineering at Xavier University of Louisiana. The program objective was to increase performance in…

THIS BULLETIN DESCRIBES SIMPLE PIECES OF EQUIPMENT AND DEVICES TO AID TEACHERS AND PUPILS IN DEVELOPING NATURE STUDY PROGRAMS, PARTICULARLY IN SITUATIONS WHERE EQUIPMENT IS TOO EXPENSIVE TO PURCHASE. ALTHOUGH IT IS DESIGNED PRIMARILY FOR ELEMENTARY TEACHERS, SOME OF THE IDEAS CAN BE USED BY HIGH SCHOOL TEACHERS. THE TEACHING AIDS SUGGESTED ARE…
