- development
- experiment is supported by data- visual, verbal or mathematical
- modeling
- conclusions made on basis of facts or premises rather than direct observation
- inferring
- broad and comprehensive statement on what is thought to be true, supported by considerable evidence and may tie together several related hypotheses
- theory
- an instrument that produces an enlarged image of an object and to show details

- differentiation
- through evolution when favorable traits replace unfavorable traits
- descent with modification
