The Virtual Vee Map proved successful in promoting student learning in the areas of inquiry and data analysis using resources and data available on the internet. A postsurvey found that a majority of students enjoyed collecting and interpreting the data to find an answer to their own inquiry question. (Contains 3 tables and 6 figures.)

The use of crude flower extracts to the principle of analytical chemistry automation, with the flow injection analysis (FIA) procedure developed to determine hypochlorite in household bleaching products was performed. The FIA comprises a group of techniques based on injection of a liquid sample into a moving, nonsegmented carrier stream of a…

This study aims to develop an indigenous science instructional model. The samples were divided into two groups. Firstly, 24 experts for designing an indigenous science instructional model using Delphi Technique. Secondly, three classrooms of Mathayomsuksa 3 students for developing an instructional model. The findings revealed that Delphi technique…

A simple, guided-inquiry investigation using stacked sandwich cookies is employed to develop a simple linear mathematical model and to explore measurement error by incorporating errors as part of the investigation. Both random and systematic errors are presented. The model and errors are then investigated further by engaging with an interactive…

The Child Development & Behavior (CDB) Branch of the National Institute of Child Health and Human Development (NICHD) seeks to improve the health and well-being of individuals from infancy through early adulthood by supporting research into healthy growth and development, including all aspects of child development. The study of typical child…

This manual informs tutors/evaluators and students about the Caribbean Examinations Council's (CXC) school based assessment (SBA) of integrated science skills. It includes directions for the teacher/evaluator and a student activity package. The SBA is done in agricultural science, biology, chemistry, integrated science, and social studies and is…

This classroom kit, designed by curriculum developers working with teachers and scientists from the SETI (Search for Extraterrestrial Intelligence) Institute, helps teachers guide students in the exploration of life through the multidisciplinary sciences of paleontology and exobiology. It reflects the real-life methods of science: making…

This paper describes part of a study undertaken to examine the relationship between dispositions to critical thinking, procedural knowledge in science, and formal reasoning. Three tests were administered to 346 grade 7 students at the beginning and at the end of the school year: California Critical Thinking Dispositions Inventory, Group Assessment…

Students designed and manufactured compact, shell-and-tube heat exchangers in a project-based learning exercise integrated with our heat transfer course. The heat exchangers were constructed from common building materials available at home improvement centers. The cost of materials for a device was less than $20. The project gave students…

This study examined whether there was a relationship between preservice elementary teachers' competency in science process skills and attitudes toward the field of science. Study data came from 46 students enrolled in an elementary math and science methods course during their first senior semester, just before entering student teaching. Study…

One of our most valuable and often overlooked resources is water. We can survive for a couple of weeks without food but only a few days without water. Having clean water to drink is a luxury. The water that comes out of our faucets does not always start off safe to drink. Most often it has visited a treatment plant prior to reaching our glasses.…

Rube Goldberg is famous for his very complex machines that accomplish everyday tasks. In this activity, students design and build a Rube Goldberg machine that will accomplish a simple task in no less than 10 steps. This activity requires a 120-360 minute time period for completion. (Author/SOE)

When asked to list some strong materials, people think of steel, concrete, and wood. In this activity, students learn about the force of compression and how it acts on structural components through a hands-on group problem. Using everyday products such as paper, toothpicks, and tape, students construct a structure that will support the weight of a…

This document represents the content of science education in California and includes the essential skills and knowledge students will need to be scientifically literate citizens in the 21st century. The standards include grade-level specific content for kindergarten through grade 8. A significant feature is the focus on earth science in the 6th…

Mastering science involves not only developing the skills of doing science, but also developing the skill of taking science. This paper describes how a teacher tried to help her students develop appropriate scientific ways of presenting explanations. The teacher employed a number of strategies as she and her students jointly constructed…
