Solve problems using a variety of strategie Pose questions for scientific investigations and make predictions about the outcomes Design and conduct a scientific investigation exploring the relationship between two variables Use appropriate tools and techniques to gather, organize, and interpret data Compare and estimate very large/very small numbers Use appropriate measurement units Read bar graphs, line graphs, circle graphs, and tables Construct explanations, including the development of simple models, for observations made Work in small teams to investigate problems, but form own conclusions Discuss the relationship between evidence and explanations Recognize and analyze alternative explanations and procedures Communicate scientific procedures and explanations Make hypotheses and design simple experiments to test hypotheses made Recognize the variables in a situation and the importance of controlling them when conducting a scientific investigation Seek information for comparing past and present scientific
