However, it is useful to consider the following general framework for a generic scientific method (see Fig. l.3): Steps in the Scientific Method 1. Making observations. Observations may be qualitative (the sky is blue; water is a liquid) or quantitative (water boils at 100°C; a certain chemistry book weighs 2 kilograms). A qualitative observation does not involve a number. A quantitative observation (called a measurement) involves both a number and a unit. 2. Formulating hypotheses. A hypothesis is a possible explanation for an observation. 3. Performing experiments. An experiment is carried out to test a hypothesis. This involves
