Second Grade Science Curriculum Map


Nature of Science

By the conclusion of second grade, students will understand that scientific inquiry has produced much knowledge about the world and that much is still unknown.  Students will investigate scientific contributions made by people everywhere in the world and use investigations in science to answer different questions.  Students will repeat observations of investigations to improve accuracy and measure length, volume, mass and temperature in appropriate units.  Students will make predictions based on observations rather than random guesses, conduct simple experiments safely to answer questions and recognize unexpected or unusual quantitative data.  Students will use scientific thinking skills, i.e. observing, communication, classifying, comparing, and predicting.
