Explain how energy entering the ecosystems as sunlight supports the life of organisms through photosynthesis and the transfer of energy through the interactions of organisms and the environment.
Describe how organisms may interact with one another.
Students use patterns, relations and functions to model, represent
and analyze problem situations that involve variable quantities. Students analyze, model and solve problems using various representations such as tables, graphs and equations.
B. Represent, analyze and generalize a variety of patterns and functions with tables, graphs, words and symbolic rules.
F. Use representations, such as tables, graphs and equations, to model situations and to solve problems, especially those that involve linear relationships.
1. Represent and analyze patterns, rules and functions, using physical materials, tables and graphs.
5. Produce and interpret graphs that represent the relationship between two variables.
Students should recognize that science and technology are interconnected, and that using technology involves assessment of the benefits, risks, and costs. Students should build scientific and technological knowledge, as well as the skill required to design and construct devices. In addition, they should develop the processes to solve problems and to understand that problems may be solved in several ways.
Students develop scientific habits of mind as they use the processes of scientific inquiry to ask valid questions, and to gather and analyze information. They understand how to develop hypotheses and make predictions. They are able to reflect on scientific practices as they develop plans of action to create and evaluate a variety of conclusions. Students are also able to demonstrate the ability to communicate their findings to others.
Students realize that the current body of scientific knowledge must be based on evidence, be predictive, logical, subject to modification, and limited to the natural world. This includes demonstrating an understanding that scientific knowledge grows and advances as new evidence is discovered to support or modify existing theories, as well as to encourage the development of new theories. Students are able to reflect on ethical scientific practices and demonstrate an understanding of how the current body of scientific knowledge reflects the historical and cultural contributions of women and men who provide us with a more reliable and comprehensive understanding of the natural world.
Students use mathematical processes and knowledge to solve problems. Students apply problem-solving and decision-making techniques, and communicate mathematical ideas.
