Maryland College and Career-Ready Standards
MD.1.0. Skills and Processes: Students will demonstrate the thinking and acting inherent in the practice of science.
1.A.1. Constructing Knowledge: Gather and question data from many different forms of scientific investigations which include reviewing appropriate print resources, observing what things are like or what is happening somewhere, collecting specimens for analysis, and doing experiments.
1.A.1.b. Select and use appropriate tools hand lens or microscope (magnifiers), centimeter ruler (length), spring scale (weight), balance (mass), Celsius thermometer (temperature), graduated cylinder (liquid volume), and stopwatch (elapsed time) to augment observations of objects, events, and processes.
1.A.1.c. Explain that comparisons of data might not be fair because some conditions are not kept the same.
1.B.1. Applying Evidence and Reasoning: Seek better reasons for believing something than 'Everybody knows that...' or 'I just know' and discount such reasons when given by others.
1.B.1.a. Develop explanations using knowledge possessed and evidence from observations, reliable print resources, and investigations.
1.C.1. Communicating Scientific Information: Recognize that clear communication is an essential part of doing science because it enables scientists to inform others about their work, expose their ideas to criticism by other scientists, and stay informed about scientific discoveries around the world.
1.C.1.a. Make use of and analyze models, such as tables and graphs to summarize and interpret data.
1.C.1.d. Construct and share reasonable explanations for questions asked.
1.D.3. Technology: Examine and modify models and discuss their limitations.
1.D.3.a. Explain that a model is a simplified imitation of something and that a model's value lies in suggesting how the thing modeled works.
1.D.3.b. Investigate and describe that seeing how a model works after changes are made to it may suggest how the real thing would work if the same were done to it.
1.D.3.c. Explain that models, such as geometric figures, number sequences, graphs, diagrams, sketches, number lines, maps, and stories can be used to represent objects, events, and processes in the real world, although such representations can never be exact in every detail.
1.D.3.d. Realize that one way to make sense of something is to think how it is like something more familiar.
