1. Observation. The observations about the world can be open-ended, this part of the experiment is important for getting children curious about their surroundings! In this dissolving experiment, the observation could be: Some solid materials dissolve in water. 2. Question. There can be no experiment without a question!
Experiment Basics. Learning Objectives. Explain what an experiment is and recognize examples of studies that are experiments and studies that are not experiments. Explain what internal validity is and why experiments are considered to be high in internal validity.
