Document Summary
Qualitative (descriptive in nature) or quantitative (involving measurements: observations systematic recording of natural phenomena; may be, hypothesis possible explanation for the observation developed based, experiment a procedure for testing a hypothesis. Most useful when: theory developed from a hypothesis consistent with experimental data upon facts collected from previous experiments as well as scientific knowledge and intuition. May be correct, but must be testable with an experiment. and is a unifying principle that explains experimental results. Scientific notation is a way to write: how do you convert from degrees celsius to kelvin and vice versa? extremely large/small numerical values in an efficient way. Joules: explain the difference between accuracy and precision. Nanotechnology is the study and production of materials and structures that have at least one dimension between 1 nm and 100 nm, where one nanometer is one billionth of a meter. Nanoparticles have unique properties that vary with size and composition. Energy the capacity to supply heat or do work.
