Laboratorios virtuales. 1º o 2º Bachillerato. Muy buenos. Requieren Sockwave Flash

Virtual Labs
The Virtual Labs Series produced by the Howard Hughes Medical Institute (HHMI) has won top honors in the Pirelli INTERNETional Award competition. More than 1,200 multimedia entries competed for the Top Pirelli Prize, which recognizes the best multimedia products designed to use the Internet to educate about science and technology. Read on...

The lab will familiarize you with the science and techniques used to make transgenic flies. Transgenic organisms, which contain DNA that is inserted experimentally, are used to study many biological processes. In this lab, you will create a transgenic fly to study circadian rhythms.

The purpose of the lab is to familiarize you with the science and techniques used to identify different types of bacteria based on their DNA sequences. Not long ago, DNA sequencing was a time-consuming, tedious process. With readily available commercial equipment and kits, it is now routine. The techniques used in this lab are applicable in a wide variety of settings, including scientific research and forensic labs.

The focus of this lab is on heritable diseases of the heart. You are cast here as a virtual intern to accompany a doctor examining three different patients. Each patient is examined using more than one diagnostic tool, and at each stage, the doctor will invite you to examine the patient yourself and ask for your opinion.

Record electrical activities of individual neurons while you deliver mechanical stimulus to the attached skin. Inject fluorescent dyes into the neurons to visualize their morphology. Identify the neurons based on the morphology and the response to stimuli, comparing them to previously published results.

Components of the immune system called antibodies are found in the liquid portion of blood and help protect the body from harm. Antibodies can also be used outside the body in a laboratory-based assay to help diagnose disease caused by malfunctions of the immune system or by infections.
This virtual laboratory will demonstrate how such a test, termed an enzyme-linked immunosorbent assay (ELISA), is carried out and show some of the key experimental problems that may be encountered.
