Details an investigation concerned with the composition of a grape to illustrate how food and nutrition topics can drive inquiry-oriented science learning. Students design experiments that surround the development of a fictitious new beverage. (DDR)

Developed is a classroom activity that illustrates the scientific method. The importance of observation, interpretation, and prediction is discussed. The activity uses pictures of the surface of Mars. (KR)

Describes how students in a geoscience course are introduced to geographic information systems (GIS), a computer-assisted system for the acquisition, storage, analysis, and display of geographic data, through a practical experience involving collecting data and inputting it into a GIS program called IDRISI. (MKR)

Provides background information on the Science Education Quantitative Literacy (SEQL) project that is designed to enhance student laboratory experiences by working together on data collection and analysis. Includes details of an activity from the project curriculum on how many drops of water can be placed on a penny. (DDR)

Surveys internet sites that provide resources for science teachers and their students. Focuses on topics related to science and society, sound, optics, professional development, and tips for searching the internet. (DDR)

Outlines how students and teachers can use the internet to gather data on earthquakes all over the world, explore the data using database and spreadsheet programs, and predict earthquakes or formulate other hypotheses. (DDR)

Building and racing mousetrap cars is a common activity in many eighth- and ninth-grade physical science classrooms. However, once students have raced their cars, most mousetrap assignments come to an end. In this article, the authors developed a project to help teachers get more mileage out of mousetrap cars. The Mousetrap Car Project addresses…

Defines action research in terms of science education, delineates the process, provides the rationale for research into practice, and gives an example of putting this process into action. Includes some tips for data collection and analysis. (DDR)

State-of-the-art digital cameras open up enormous possibilities in the science classroom, especially when used as data collectors. Because most high school students are not fully formal thinkers, the digital camera can provide a much richer learning experience than traditional observation. Data taken through digital images can make the…

The study of "zonation", the distribution of plants and animals into distinct spatial areas, is a great way to introduce students to basic ecological concepts. Students can conduct methodical, quantifying surveys of zones in areas as diverse as mudflats, beaches, forests, wetlands, and fields. Students collect data from these areas with field…

Presents an instructional framework for real-world, problem-based studies that can be used in a variety of settings. Discusses background knowledge, problem exposition, data collection and analysis, data synthesis and solution presentation, and career information. (JRH)

Many varieties of data acquisition systems are now available for science classrooms. Most systems consist of a range of sensors--typically called probeware--connected to an interface unit usually described as a datalogger due to its capacity to record data from these sensors. Although some systems operate independently, most units connect to a…

Probeware is increasingly being implemented in science classrooms because it is less expensive than it used to be and improvements in hardware and software have made it more accessible to students and teachers. Many probes or sensors can now simply be connected to a computer, calculator, or other handheld device, and will immediately begin to…

Explains the use of contingency tables as a tool in assessing variables to determine whether a relationship exists. Develops an example hypothesis step-by-step, noting the scientific processes and attitudes being addressed. Cautions that a large difference, which suggests a relationship, is not explanation since correlation does not guarantee…

This activity uses ice crystals to introduce middle school and high school students to the collection, preparation, examination, and manipulation of scientific data. (PR)
