Science Sampler : The scientific method -- Is it still useful?
Many scientists and science educators contend that a structured scientific method does not exist, while others might argue that the scientific method is too simplistic in its approach to scientific inquiry. This article addresses the dilemmas surrounding the scientific method, and provides suggestions that will enable you to ?meld the method with process skills.?
Ocean Surface Topography from Space
The Global Conveyer Belt shows how the oceans move energy from the tropics to the poles and back again in order to moderate Earths climate. This is accomplished through long-term ocean circulation. This on-line tutorial about ocean circulation features text, pictures, and satellite imagery with links to topics such as ocean heat transport, the coriolis effect, hills and valleys in the ocean, measurement and motion in the wind and ocean, changes in sea height over time, and El Nino.
5.3 Global warming
To be able to understand the importance of the environment for our health, we need to know a little about the interdependence between environment and humankind. This unit will look at interactions between plants, animals and the physical and chemical environment, as well as considering ways in which humans have altered, and are altering this environment. These changes have health implications that are not always immediately obvious. Frequently, we initiate changes that are going to have their ef
Rice farming and rural life in Vietnam
Photographs and text tell the story of rice and rural life in Southeast Asia, with an emphasis on the highlanders, or Montagnards.
Plant Tissue Culture Systems as Instructional Tools in the Biological Sciences
To introduce students to basic techniques of plant tissue culture and determine the effects of amino acids on growth of carrot or corn plant callus.
Geranium bloom
Time-lapse photos or video show progressions from the start of an event to the end of the event. These time-lapse photos illustrate the opening of a geranium flower to absorb sunlight. Biological processes require time.
Mealworm pupa
Mealworms go from the larval stage to the pupal stage. In the pupa, they transform into the adult beetle.
