This is an investigation of whether the real world behaves as predicted by the hypothesis. Scientists (and other people) test hypotheses by conducting experiments . The purpose of an experiment is to determine whether observations of the real world agree with or conflict with the predictions derived from a hypothesis. If they agree, confidence in the hypothesis increases; otherwise, it decreases. Agreement does not assure that the hypothesis is true; future experiments may reveal problems. Karl Popper advised scientists to try to falsify hypotheses, ., to search for and test those experiments that seem most doubtful. Large numbers of successful confirmations are not convincing if they arise from experiments that avoid risk.  Experiments should be designed to minimize possible errors, especially through the use of appropriate scientific controls . For example, tests of medical treatments are commonly run as double-blind tests . Test personnel, who might unwittingly reveal to test subjects which samples are the desired test drugs and which are placebos , are kept ignorant of which are which. Such hints can bias the responses of the test subjects. Furthermore, failure of an experiment does not necessarily mean the hypothesis is false. Experiments always depend on several hypotheses, ., that the test equipment is working properly, and a failure may be a failure of one of the auxiliary hypotheses. (See the Duhem–Quine thesis .) Experiments can be conducted in a college lab, on a kitchen table, at CERN's Large Hadron Collider , at the bottom of an ocean, on Mars (using one of the working rovers ), and so on. Astronomers do experiments, searching for planets around distant stars. Finally, most individual experiments address highly specific topics for reasons of practicality. As a result, evidence about broader topics is usually accumulated gradually.
Just wondering -I have a child who struggles with comprehension issues and decoding strategies but has fluency. The school is doing a RTI for the next 12 weeks to document If he has a reading disability using this program . He has been in reading recovery for the last years and did not have great progress but per LD director at school they can't test for LD because they were not doing interventions specifically for comprehension ??!?!???!? I'm sort of livid! But don't know if I have the right to be! Ahhhhkkk! Some input would be great - an upset parent oh and there doing this program one on one not in a group setting wich it seems like it's supposed to be in a group! -upset Mom
Once the fire is detected, the alarm system will alert the fire department and relevant authorities on your behalf, saving you precious time for evacuation.
Confinement of the fire:
It is vital once a fire is detected and the alarm sounds that fire retardant doors and paneling contain the fire within the initial area. This is critical not only for staff and employee's to evacuate the building but also to safeguard against any wider spread damage.
Fire retardant doors and paneling are a requirement under the National Building Regulations (SABS 400). As part of our company credo, we offer a free risk assessment and will help you to improve risk areas.
Fighting the fire:
Fire Action offers a variety of equipment assist with bringing the fire under control at the earliest possible stage. This includes fire extinguishers, fire hoses, water sprinkler systems and gaseous retardants. The decision as to which is best for you is determined by your specific environment and our highly trained staff would be happy to advise you based on a full assessment.
