This document provides an overview of key concepts in science including hypothesis, observation, experiment, variable, control group, procedures, data, precision, accuracy, inference, and evidence. It then lists steps for a scientific experiment and asks questions about scientific investigations and models. The questions cover topics such as the four things scientists do, how people solve problems, types of scientific investigations, the difference between observations and inferences, why scientists' conclusions are based on evidence, and ways to investigate different types of questions.
