In this activity, I show how high school students apply their knowledge of density to solve an unknown variable, such as thickness. Students leave this activity with a better understanding of density, the knowledge that density is a characteristic property of a given substance, and the ways density can be measured. (Contains 4 figures and 1 table.)

NASA CONNECT is an annual series of free integrated mathematics, science, and technology instructional distance learning programs for students in grades 5-8. This video presents the World Space Congress 2002, the meeting of the decade for space professionals. Topics discussed range from the discovery of distant planets to medical advancements,…

Procedural understanding should be taught to students for an understanding of the 'nature of science'. Considers some of the concepts of evidence that are particularly important to biology, and discusses how and why these ideas could be taught. (Contains 21 references.) (Author/YDS)

Describes how teachers can use wheels of tricycles, bicycles, and trains to stimulate children with mathematics, relative position, and engineering concepts. Techniques are offered for measuring circumference of a bicycle wheel, gear ratios, and pedal wheel circumferences. Comparative data are given for various sized wheels. (Author/SA)

Explains the implementation of forensic science in an integrated curriculum and discusses the advantages of this approach. Lists the forensic science course syllabi studied in three high schools. Discusses the unit on polymers in detail. (YDS)

Demonstrated in this article are some of the capabilities of a spreadsheet program using data obtained in gas law experiments and a computer interface system. The ability to organize and analyze data which a computer can provide for the student is emphasized. (KR)

Plant tissue culture has developed into a valid botanical discipline and is considered a key area of biotechnology, but it has not been a key component of the science curriculum because of the expensive and technical nature of research in this area. This manual presents a number of activities that are relatively easy to prepare and perform. The…

Discusses the advantages of using discrepant events in elementary school science classrooms in terms of motivation and problem solving skills. Describes the materials, procedures, and reasons behind five discrepant activities. (YP)

Described in this article is a problem-solving activity which integrates the application of microcomputers with the learning of physical chemistry. Students use the program with spectroscopic data to calculate the thermodynamic properties and compare them with the values from the thermochemical tables. (Author/KR)

The main advantage of using these concepts lies in the reduction of algebraic work involved in solving certain dynamics problems. A brief analytical treatment of the acceleration center and a description of a virtual work principle for equipollent systems in the kinetics of rigid bodies are provided. (MVL)

In May 2005, the International Technology Education Association (ITEA) was funded by the National Aeronautics and Space Administration (NASA) to develop curricular units for Grades K-12 on Space Exploration. The units focus on aspects of the themes that NASA Engineers and Scientists--as well as future generations of explorers--must consider, such…

Lunar Nautics is a hands-on curriculum targeted to youth in grades 6 to 8, that allows the students to design, test, analyze and manage a space mission from initial concept to project funding. Lunar Nautics provides opportunities for development of problem solving skills and critical thinking skills that are needed to design, organize and manage a…

This book offers broad, practical strategies for teaching science and engineering courses and describes how faculty can provide a learning environment that helps students comprehend the nature of science, understand science concepts, and solve problems in science courses. The student-centered approach focuses on two main themes: reflective writing…
