CEM 141 Lecture Notes - Lecture 1: Scanning Tunneling Microscope, Falsifiability, Atomic Theory
Document Summary
Scientists : ask questions, design experiments, gather and analyze data and evidence, make claims, develop models, explanations and theories. Scientific questions can be answered by: doing experiments, making observations, taking measurements. *all must be done in a replicable way* Atomic theory- the idea that matter is composed of atoms. You need evidence if you are going to make claim. A model will allow you to predict what will happen under any given circumstances. Can be a drawing, a graph, a diagram or an equation. We use models to help us make sense by: Predicting what will happen, they make testable and quantifiable predictions. We could imagine lots of different models that would help us understand when we add cold to hot. We can develop an explanation or scientific theory to help us explain why. Often there are many levels of responses that are possible. Reasoning: the connection between your claim and evidence.
