scientific method

scientific method

1. First we need scientific hypotheses: • Use the words • Amount; depends on; quantity; temperature; solvent (e.g. coffee)

2. A pendulum is any mass which swings back and forth on a rope, string, or chain. Pendulums can be found in old clocks and other machinery. A playground swing is a pendulum and so is the ride in the photograph below. The length of time it takes the mass to swing all the way over and back, once, is called the period of the pendulum.

3. The Scientific Method is traditionally presented in the first chapter of science textbooks as a simple recipe for performing scientific investigations. Though many useful points are embodied in this method, it can easily be misinterpreted as linear and "cookbook": pull a problem off the shelf, throw in an observation, mix in a few questions, sprinkle on a hypothesis,

   • The linear, stepwise representation of the process of science is simplified, but it does get at least one thing right. It captures the core logic of science: testing ideas with evidence.
     • 1.The simplified, linear scientific method implies that scientific studies follow an unvarying, linear recipe.
       • The simplified, linear scientific method implies that science is done by individual scientists working through these steps in isolation.
         • The simplified, linear scientific method implies that science has little room for creativity.
           • The simplified, linear scientific method implies that science concludes.

4. The process of science is iterative. Science circles back on itself so that useful ideas are built upon and used to learn even more about the natural world. This often means that successive investigations of a topic lead back to the same question, but at deeper and deeper levels.
