When teachers don't understand
Teaching should be informed not only by the content of the discipline but also by the lives of the students.
ATP sünteesi mõjutavad tegurid
TÜ Loodusteadusliku hariduse lektoraadi vastavatel kursustel (Loodusteaduste visualiseerimine) osalenud õpetajate koostatud interaktiivsed mudelid bioloogiliste protsesside tundmaõppimiseks. Kuigi mudeleid ei saa lugeda lõplikult viimistletuks, on nad õppeprotsessi visualiseerimiseks asjakohased: kasvõi ideede saamiseks. Kasutajal on soovitav fail enne oma arvutisse salvestada ning vajadusel täiendada.
Cactus
Cacti have many thorns that prick potential predators if touched or eaten.
Arachnids: Tick
One reason why ticks are considered to be arachnids is because they do not have antennae like insects do. Ticks suck blood from animals and are sometimes difficult to remove from the host's skin.
Female Artemia closeup
Close-up full body view of a female Artemia under one quarter-inch in size.
The San Joaquin kit fox
San Joaquin kit foxes are nocturnal and hunt small mammals at night. They make dens and stay in them during the day to conserve water and energy.
EPTOMS Ozone (7-26-96 - 12-4-00)
This animation shows the total ozone as measured by Earth Probe TOMS since the earliest measurements by that instrument. Days on which no data was taken appear as blank.
Global Methane Isosurface Wave
An animation of a three-dimensional isosurface of global methane in the atmosphere evolving over time, from a global data assimilation model. The globe of the Earth starts out opaque, then becomes transparent in order to more clearly see the structure of the isosurface. The isosurface exhibits wave breaking in the southern hemisphere.
The Middle East Dust Storm
Dust storms are an every day occurrence in Saudi Arabia. This storm is of an unusual size.
Landsat Witnesses the Destruction of Mesopotamian Ecosystem
In one of the greatest ecological disasters of our time, the ancient marshlands of Mesopotamia are systematically being converted to dry salt flats as a result of human mismanagement of the regions water resources. Landsat satellite imagery reveals that in the last 10 years, wetlands that once covered as much as 20,000 square km in parts of Iraq and Iran have been reduced to a small fraction of their original size. The authors of a new report released by the United Nations Environment Programmes
Hurricanes as Heat Engines
As water vapor evaporates from the warm ocean surface, it is forced upward in the convective clouds that surround the eyewall and rainband regions of a storm. As the water vapor cools and condenses from a gas back to a liquid state, it releases latent heat. The release of latent heat warms the surrounding air, making it lighter and thus promoting more vigorous cloud development.
Hurricane Hernan, September 1, 2002
Hurricane Hernan located 625 miles west-southwest of the southern tip of Baja California. Hernan has maximum sustained winds of 130 knots with gusts to 160 knots. The overall structure of the storm is shown in this animation with rain amounts being shown through color. Yellow represents 0.5 inches of rain or more, green shows 1.0 inches of rain and red shows 2.0 inches or more.
Digital Earth Workbench: 3D Hurricane Luis
The Digital Earth Workbench is an interactive application that runs on a SGI Onyx Infinite Reality system and is controlled by an Immersive Workbench, tracked stereo glasses, and a tracked wand. The application allows an unprecedented freedom to roam georeferenced datasets at multiple resolutions and timescales. This animation is one of a series of direct screen captures of the application in operation. The occasional menu appearance denotes direct intervention by the operator to add or delete d

Ozone measurements from Earth Probe TOMS for February 1, 1997 through May 31, 1997 showing the formation of an Arctic ozone hole
Arctic Ozone from TOMS: September 1, 1999 through November 30, 1999
Total ozone over the arctic for September 1, 1999 through November 30, 1999, as measured by Earth Probe TOMS
Global TRMM Rainmap, August - September 2003 (WMS)
This is a three-hour global rainmap from August 27 through September 8, 2003, as observed by the TRMM satellite.
Ethical Issues in Public Health
Lectures and small group discussions focus on ethical theory and current ethical issues in public health and health policy, including resource allocation, the use of summary measures of health, the right to health care, and conflicts between autonomy and health promotion efforts. Student evaluation based on class participation, a group project, and a paper evaluating ethical issues in the student's area of public health specialization.
Bioinformatics and Computational Biology Solutions Using R and Bioconductor
Covers the basics of R software and the key capabilities of the Bioconductor project (a widely used open source and open development software project for the analysis and comprehension of data arising from high-throughput experimentation in genomics and molecular biology and rooted in the open source statistical computing environment R), including importation and preprocessing of high-throughput data from microarrays and other platforms. Also introduces statistical concepts and tools necessary t
Training Methods and Continuing Education for Health Workers
This course in Training Methods and Continuing Education for Health Workers identifies the role of training and continuing education as an important component of health service and personnel management. Participants will be guided through the steps of planning training and continuing education activities for a range of health workers from managers to village volunteers. The course draws on real life examples from community-directed onchocerciasis control, village health worker programs, and pate
Problems in the Design of Epidemiologic Studies (Grant Writing)
Presents the methodologic and logistic problems involved in designing and conducting epidemiologic studies. Students participate in the preparation of a research protocol for a study in a human population. Offers an opportunity to critically evaluate the adequacy and scientific merit of research protocols, develop an appreciation of the ethical aspects of conducting research involving human subjects, and apply methods and principles learned in earlier (340.601 - 603) and current courses to speci
