Argument-Driven Inquiry (ADI) is an instructional model that enables science teachers to transform a traditional laboratory activity into a short integrated instructional unit. To illustrate how the ADI instructional model works, this article describes an ADI lesson developed for a 10th-grade chemistry class. This example lesson was designed to…

Imagine recreating a tsunami's force in a bathtub or exploring the potential of geothermal energy by using steam from a kettle to illuminate a light bulb. These types of activities and more are offered in Matthew Levy and Mario Salvadori's collection of experiments and demonstrations in Earthquakes, Volcanoes and Tsunamis. More than 30 easy and…

A laboratory experiment designed as part of an upper-level undergraduate analytical chemistry course is described. Students investigate two popular soft drinks (Red Bull Energy Drink and sugar-free Red Bull Energy Drink) by NMR spectroscopy. With assistance of modern NMR prediction software they identify and quantify major components in each…

This activity discusses a unit exercise in which a physics practical was implemented during a laboratory session. The lab practical design was centered on Newton's Second Law. The practical was implemented in a high school setting. Further, through the administration of both a pre and post test we were able to assess the effectiveness of the lab…

The aim of this project is to study the quality of the discussions in groups of students during laboratory work. The project builds on a study of the role of communication in science classrooms with students aged 14-15 years. An intervention with role-playing for example reporting to another group is carried out to foster discourses that focus…

Most homes in developed countries have a sophisticated data acquisition board, namely the PC sound board. Designed to be able to reproduce CD-quality stereo sound, it must have a sampling rate of at least 44 kHz and have very accurate timing between the two stereo channels. With a very simple adaptation of a pair of regular PC microphones, a…

Teaching Science can only be successful if we are able to answer the challenges of the 21st century. Teaching Physics, Chemistry and Biology with the traditional methods is unintelligible and considered unnecessary for most students. This situation needs to be changed. Students can only develop their abilities and skills to the full extent and can…

Instructional technology is a growing field which uses technology as a means to solve teaching and learning challenges, both in the classroom and outside the classroom that is in distance learning environments. Multimedia is an interactive instructional technology used in the classroom for teaching learning process has a wide significance to the…

A general science experiment for high school chemistry students might serve as an excellent review of the concepts of solution preparation, solubility, pH, and qualitative and quantitative analysis of a common food product. The students could learn to use safe laboratory techniques, collect and analyze data using proper scientific methodology and…

Both of the national efforts to reform education (AAAS, 1993; NRC, 1996) promoted professional development experiences that engage teachers in authentic scientific research. This qualitative multiple case study used legitimate peripheral participation (LPP) as a way to examine the process by which teachers became a part of the laboratory community…

The effectiveness of mixed sensory mode presentation for beginning and experienced learners of Chinese characters as second language was investigated. Experiment 1 found that inexperienced 7th graders performed better on meaning recall in the mixed visual-audio mode than the visual mode presentation, but the superiority of these two formats was…

This article informs about the formation of a school's Institutional Review Board (IRB), presents examples of research that IRBs often encounter, elevates awareness of human subjects research concerns for faculty and staff, and discusses how emerging requirements for science competitions may affect schools, staff and students. An IRB is the group…

A 2 m long wooden beam provides an ideal demonstration tool for exploring moments. A class set is cheap and can be used at introductory and advanced levels. This article explores how such beams can be used to support learning about moments, equilibrium, vectors, and simultaneous equations. (Contains 7 figures.)

The surface-to-volume ratio is an important quantity in thermal physics. For example it governs the behaviour of heating or cooling of physical objects as a function of size like, e.g. cubes or spheres made of different material. The starting point in our paper is the simple physics problem of how cheese cubes of different sizes behave if heated…

The National Council for Social studies defines Social sciences as the "integrated study of the social sciences and humanities to promote civic competence". At the elementary school level, social studies generally focuses on the local community and family. By middle and high school level, the social studies curriculum becomes more…
