Uses computers to help students identify variables controlling pendulum period. A program written in BASIC for the Apple computer is provided. The activities are useful for developing science skills, mathematics skills, and computer skills. (PR)

Provides background information on DNA fingerprinting, and describes exercises for introducing general biology students at the high school or college level to the methodology and applications of DNA fingerprinting. (PR)

Describes how lectures, laboratories, and role playing can be used to introduce students to the importance of water quality of water used for plant growth. (PR)

Describes having students write lab reports that concentrate more on writing and independent thought. Students take the role of scientists writing about their findings for publication. The teacher acts as a journal editor, reading the reports and either accepting them for publication or suggesting ways for improvement. (PR)

Presents a problem-solving activity in which students determine the effects on the water level in a pool when rocks are removed from a boat floating in the pool and placed into the water. Students discuss the problem, design an experiment to test solutions, conduct the experiment, and draw conclusions. (MDH)

Clarifies the issues of animal rights as they effect animal use in research and education through an examination of the current use of animals, a historical look at animal use, and a consideration of the philosophical underpinnings of the animal rights and pro-use viewpoints. (PR)

Discusses possibilities for improving undergraduate-level general-education biology courses, particularly through the development of interesting and focused laboratory presentations. Advocates problem-based learning and improving the communication skills of laboratory teaching assistants. (Author/WRM)

Describes two science activities concerning water density and shares an idea for combining these activities into a third, completely new activity. Demonstrates the joy of rekindling the spirit of scientific thinking in a typical classroom. (PVD)

Discusses the importance of science education in early childhood education and describes different approaches in incorporating physics into the preschool curriculum. Provides examples of experiments and encourages parent participation in children's science activities. Concludes by looking at science as an equity issue and emphasizes that science…

In this article, the author discusses "The Biology of Food" course. This course--a large lecture course with no laboratory section--is a mixture of kitchen chemistry, post-eating food metabolism, origins of different foods (from crop breeding to evolution), and ecological and environmental impacts of farming and harvesting practices. Nearly every…

Current reform documents place a strong emphasis on students' understandings of the nature of science (NOS). Interestingly, the importance of this educational outcome is not new and has been agreed upon as important by most scientists and science educators for the past 100 years. Despite numerous attempts, including the major curricular reform…

As a science subject leader and year 6 teacher in North Bristol, the author has spent the last few months exploring how an interactive whiteboard (IWB) can be used to teach science skills, particularly those that are repeatedly highlighted as problematic, such as analysis and evaluation of evidence. The IWB came with software called…

Question-asking is a basic skill, required for the development of scientific thinking. However, the way in which science lessons are conducted does not usually stimulate question-asking by students. To make students more familiar with the scientific inquiry process, we developed a curriculum in developmental biology based on research papers…

The Zimbabwe Secondary School Science Project (ZIM-SCI) developed student study guides, corresponding teaching guides, and science kits for a low-cost science course which could be taught during the first 2 years of secondary school without the aid of qualified teachers and conventional laboratories. This ZIM-SCI study guide presents activities…
