CEM 141 Lecture Notes - Lecture 2: Scientific Modelling, Falsifiability, Scientific Theory
Document Summary
Can be a drawing, graph, diagram or an equation. We use them to help us make sense by explaining how something happens and predicting what will happen. Allows us to explain why a phenomenon occurs. Evidence: the data or the scientific principle being used to support your claim. Reasoning : the connection between your claim and evidence. The best available explanation of the existing evidence data or observation. Is falsifiable (can be proven false by experiment and data) May change over time as new evidence becomes available. Questions, facts, laws, hypotheses, and theories (slide 13) They retract and repel each other depending on distance. Electron shielding allows valence electrons to be shared. Electron clouds shift do to nuclear attraction.
