they are cold blooded and the cold weather makes them slower. Being cold blooded‚ means that it adapts to the climate more as the temperature changes. Experimental Design The controlled group is the group where all the mealworms where at room temperature. The experimental variable was that we needed warm water and ice. The experimental set-up was that we made a hot and cold climate for the mealworms. For the hot climate the temperature kept rising and the cold climate went down

Special Methods Special methods of communication are methods that are used to help a service user with specific language needs to communicate. These methods are non-written and non-verbal communication for service users that suffer from impairments which can cause then to communicate effectively (Classroom Notes‚ 2014) The first special method is British Sign Language (BSL) which is a method of communication that is used to communicate with service users who have a hearing impairment. BSL can be

(DPPH) for estimating antioxidant activity Songklanakarin J. Sci. Technol.‚ 2004‚ 26(2) : 211-219 The use of the stable free radical diphenylpicrylhydrazyl (DPPH) to estimate the activity of antioxidants is reviewed. Current applications of the method are examined‚ particularly the use of the parameter EC50 (substrate concentration to produce 50% reduction of the DPPH). Some recommendations are made as to the most suitable ways of carrying out this assay and evaluating the data produced. Key

Introduction In order to identify new materials‚ scientists use a variety of chemical and physical methods to determine molecular masses. One of these methods includes the Dumas method for determining the molecular weight of a volatile liquid. This method‚ which was proposed by John Dumas in 1826‚ makes use of a volatile liquid (vaporizes at a relatively low temperature) and allows this liquid to be heated in a water bath to a known temperature and escape from a flask through a tiny opening (Giunta

THE SCIENTIFIC METHOD A ‘Hypotheses‚’ said Medawar in 1964‚ ‘are imaginative and inspirational in character’; they are ‘adventures of the mind’. He was arguing in favour of the position taken by Karl Popper in The Logic of Scientific Discovery (1972‚ 3rd edition) that the nature of scientific method is hypothetico-deductive and not‚ as is generally believed‚ inductive. B It is essential that you‚ as an intending researcher‚ understand the difference between these two interpretations of the

Survey Research * The major purpose of all surveys is to describe the characteristics of a population. * Rarely is the population as a whole studied‚ however. Instead‚ a sample is surveyed and a description of the population is inferred from what the sample reveals. Types of Surveys * There are two major types of surveys: cross-sectional surveys and longitudinal surveys. * Three longitudinal designs commonly employed in survey research are trend studies‚ cohort studies‚ and panel studies
