Explain how observations can lead to new knowledge and new questions about the natural world.
In prior grades students learned that scientific investigations involve trying to answer questions by making observations or trying things out. In grades 2-3 students learn to conduct different kinds of investigations. Although students may not yet be able to plan investigations alone, they can carry out investigations in collaboration with other students and support from the teacher. Actions may include observing and describing objects, events, and organisms, classifying them and making and recording measurements. Students should also display their data using various tables and graphs, make inferences based on evidence, and discuss their results with other students.
Scientific investigations are designed to gain knowledge about the natural world.
